Abstract
The invention relates to a double-cropping wheat cultivation method. Wheat varieties of jinling No.1 and jinling No.2 are chosen, and jinling No.1 and jinling No.2 have already obtained the national new plant variety right. Wheat is planted in northwestern spring wheat areas which are large in temperature difference day and night and distinctive in season. The first crop of the wheat is sown in late February or early March and harvested before July 3rd, and it takes 78 to 92 days from emergence to maturing; the second crop of the wheat is sown before July 5th and harvested in the middle of September and early October, the growth period is about 90 days or so, and the yield at the year of the two crops is more than 1000 kilograms per mu. The double-cropping wheat enables growth and development rules of spring wheat to be changed violently, gives full play of the advantages of the spring wheat, widens the planting range of the spring wheat, and breaks a traditional production pattern of single-cropping.
Description
Technical field
The invention belongs to wheat cultivation technical field, particularly a kind of " two batches, a wheat " wheat cultivating method.
Background technology
In all age, take the vast region of China that wheat is principal item, due to weather, annual wheat can only be planted a season.Along with global warming, also there are great changes in the weather of north of China, and the warm time in the four seasons is elongated, and the heat of exposing to the sun is come ahead of time, and hot intensity is large, and illumination resource is more abundant, brings larger difficulty to traditional wheat planting.How, according to climatic variation, further improving wheat yield is the significant problem of this technical field.Solution has two: the first, plants and cultivate high temperature resistant wheat breed, and difficulty is larger at present; The second, cultivate short wheat breed breeding time, early recover and plant.
The present invention has taked the second way; cultivated shorter Bell's wheat one (kind power number: CNA20060438.4) with Bell's wheat two (kind power number: CNA20060439.2) kind breeding time; this kind has been applied for national new variety of plant protection, has obtained certificate.
Summary of the invention
Technical problem to be solved by this invention is to overcome 1 year defect of a batch of existing wheat planting, provides an a kind of wheat two batches of wheat cultivation technology.
The present invention realizes according to following proposal:
One two batches, wheat wheat cultivating method, kind selects to have obtained Bell's wheat one and the Bell's wheat two of national new variety of plant power, large at day and night temperature, spring wheat district, the northwest plantation of making a clear distinction between the four seasons, first batch by the end of February or the beginning of March sowing, and harvesting before July 3, from emerging to ripe 78-92 days; Second batch of sowing before July 5, harvesting at the beginning of mid-September and 10 months, about 90 days vegetative period, two batches of totals are when annual production is over 1000 kilograms of per mu yields.
The cultivation step of first batch of wheat is:
1) selection of land, whole and basal dressing routinely;
2) sowing
Thickness of sowing: broadcast the grain about 420,000/mu that can germinate, protect into fringe 400,000 left and right;
Sowing width: with 12 row sower wide-and narrow-row sowings, narrow row 12cm, wide row 18cm;
Sowing depth: face smooth soil property in field is carefully melted, seed level 3-5cm, broadcasts afterwards with the light earthing of wooden rake, in the whole overburden soils of seed, guarantees emergence rate;
3) prevent and kill off weeds in field
Agricultural chemicals is selected chlortoluron or prometryn to be watered to spray, or chlortoluron mixes soil after being watered and spread fertilizer over the fields, and prevents and kill off field broad leaved weed;
4) pour water
About April 20, fill with a water, and impose fertilizer; The second water will be filled with April 26-28; The 3rd water was filled with May 5-10; The 4th water and later each water are looked the dry wet situation of field face, Changes in weather situation, and the decision of wheat upgrowth situation, general wheat is filled with water left and right from emerging 6 times to maturation;
5) topdress
Wheat 3-4 leaves fill with a water and mu chases after 7.5 kilograms of left and right of 15 kilograms+diammonium phosphate of urea;
6) pest control
From wheat booting to maturation, at least prevent and treat three times, every minor tick 10-13 days, pesticide dosage flolimat+phoxim+Avermectin 50ml+ aphid prestige of going out, is evenly sprayed at Mai Zhushang, can not repeat to spray;
7) harvesting
At wheat, enter wax ripeness latter stage, cauline leaf is yellow dry, and wheat hardening, just can gather in.
The cultivation step of second batch of wheat is:
1) wholelyly and basal dressing
After first batch of little wheat harvesting, utilize the time to apply base manure, with rotovator, revolve 2-3 times, revolve dark 10cm left and right, a kind of farm tools is put down and is suppressed one time with stone roller is light;
2) sowing and line-spacing
With 12 row sower wide-and narrow-row sowings, wide row 18cm, narrow row 12cm, seed level 3-5cm,
Seeding quantity is calculated with following formula:
3) vernalization with emerge
After Wheat Species, speed is oozed ,Jiang field, field face with little water and is drenched and to be advisable, and must guard against broad irrigation;
4) pour water and topdress
Water will be filled with in time, diligent filling; Base manure is wanted heavy dressing; Topdress quick-acting, mu chases after 15-20 kilograms, urea, early chase after, and wheat three leaf left and right start;
When wheat growth will be seen it, sees ground, see soil moisture content and determine to the later irrigation period of 5 leaves and number of times: rainy can filling; Earth's surface is dry and cracked will fill with; The ground that soil water-reataining fertilizer-keeping is good can be filled with less; Easily ooze easily dryly and suitably fill with more; The frequency of irrigation of second batch of wheat is generally no less than seven water;
5) weeding and insect protected
Wheat 3-4 leaves evenly spray wheatland with 2.4-D butyl ester, and emphasis is prevented and kill off broad leaved weed; Wheat eliminates aphis with flolimat+phoxim+Avermectin is anti-after emerging, and blackly touches worm, mythimna separata etc.; During wheat growth, also will hold concurrently later and prevent and treat two spotted spider mite, the blue or green worm of Lay etc., once, wheat is no less than four or five times throughout one's life in control in general about 13 days;
6) harvesting
The wheat wax ripeness end of term, seed hardening, stalk leaf is also yellow dry, harvesting in time.
One two batches, wheat violent change Spring Wheat Growth law of development, brought into play spring wheat characteristic advantage, expanded spring wheat planting range, broken 1 year traditional mode of production general layout of a batch, filled up continuous kind of spring-spring wheat, winter-spring wheat is handed over the farming pattern of planting, cultivated land resource and natural lighting resource have effectively been utilized, the quantum of output of having excavated unit are wheat, has significantly improved wheat yield, for solving people's food problem and grain yield, tops bar and has opened up a new way.
Wheat is one of essential cereal crops of the mankind, is also the staple food of human survival, and its nutrient content is abundant, is that other cereal crops are incomparable and replace.No matter within 1 year, can only plant a season China and even world wheat spring wheat or winter wheat, and yield poorly.After one two batches, wheat is studied successfully, thoroughly change wheat farming history, broken traditional kind of wheat present situation.During one 1000 kilograms of two batches, wheat per mu yields, 2.8 yuan of meters of one kilogram of wheat, 2800 yuan of per mu yields, except 800 yuan of the expenses such as two seasons chemical fertilizer used, agricultural chemicals, tractor-ploughing, harvesting, 2000 yuan of net profits.

2, feature
First batch of Ningxia plantation, from planting ripe 123 days, from emerging by ripe about 90 days; Second batch from being seeded into ripe 82 days, from emerging by ripe 75 days.Totally 9 leaves.The 4 leaves angle of growing is below large, 5 leaves are gradually little above, during booting, stem wax increases, and reaches maximum after heading, and stem is bright canescence, dark green leaf, during heading, fringe is burst boot leaf and is exposed, and grows into apart from boot leaf ear tongue 1 ㎝ left and right bloom along boot leaf sheath inner side, and fringe exceeds the boot leaf ear tongue 1 whole tassel blossom in ㎝ left and right closely to be finished, the stamen clever shell that spues in fringe top starts grouting, and after slurry is full, to strut clever shell visible for seed.Plant height 65 ㎝ left and right, basal part of stem one or two internode length and width are respectively 2.3,0.4,5.1,0.42 ㎝; Fringe is for there being the close shape of awns conical tower, main spike length 10 ㎝, wide 2.5 ㎝, thick 2.2 ㎝, 17, every fringe small ear, more than 70, the heavy 3.0g of fringe grain left and right, each bunch of grain number per spike mainly contain lotus flower fringe account for whole grain number per spike 50.0%, companion's fringe account for whole fringe grain 33.0% and not branched ear (single fringe) account for whole fringe grain 17.0% and form.Sterile lemma is oval, clever mouth is sharp, and awns is middle length three awns formulas, and the nearly ovum of seed, green lake, cutin, full, more than thousand kernel weight 45.0g.
This kind stem stalk is sturdy upright, high resistant to lodging, tillers less, is applicable to slightly close plantation.When first batch, fringe head and second batch of plantation, size differences is little, and when ripe, boot leaf and the nearly yellow-white of fringe are gradually dry, and under fringe, joint is slightly crisp, and disconnected fringe phenomenon has clashed.
Nature Resistant Gene To Rust, powdery mildew etc., wide adaptability, is applicable to two batches of the 1 year kinds in north province territory that day and night temperature makes a clear distinction between the four seasons greatly, is also applicable to east, the relatively less region winter wheat of southern rainwater and after receiving, does the alternately plantation of second batch of wheat.
two, two batches of concrete cultivation steps of a wheat
In the large region of the clearly demarcated day and night temperatures of four seasons weather such as Ningxia, two batches of the continuous croppings in multiple fringe wheat breed 1 year with a spring habit, allow wheat complete the normal mature that grows, and in the time of also will robbing, skilful kind obtains high yield, is a new wheat class tillage control measure.We were called for short two batches, a wheat with same multiple fringe wheat breed continuous tillage control measure of planting two batches in same ground in 1 year.First batch, (at the beginning of 3 months by the end of February) sowing while thawing 5-8 ㎝ on spring temperature rise earth's surface, harvesting at the beginning of 7 months by the end of June.Before July 5, robbed time sowing for second batch, results at the beginning of mid-September to 10 month.From planting to, receive about 122 days for first batch, from emerging to gathering in the crops about 90 days, second batch, from planting to, receive about 87 days, from emerging to gathering in about 79 days.
1, first batch (spring sowing---the summer harvest)
1) selection of land, whole ground and basal dressing
Select fertile soil, preservation capacity of water and fertility is good, and physical features is smooth higher, and field face is smooth, and difference of height is no more than 10cm, and it is convenient to irrigate, and draining is unimpeded.Autumn crops was received and was wanted afterwards the smooth filling foot of dark plow harrow a kind of farm tools winter water the first year.At the beginning of 3 months by the end of February, earth's surface thaws about 8cm, with disk harrow or rotovator, ground rake (revolving) pine is flattened, the fertile 15 kgs/acre of mixing of 50 kgs/acre+K of 50 kgs/acre+urea of two ammoniums are mixed to even use is hand steered is with the disposable Tanaka of being sown into of 12 row (14 row) sower, a kind of farm tools is flat seals sowing afterwards in or two days.
2) sowing
Thickness of sowing: the wheat breed that 1 year kind is two batches is multiple fringe wheat series of products, its big panicle many grains per panicle, stalk is thick, individual growth is healthy and strong, less tillering, thickness of sowing, can not be rare, can not be close, generally broadcast can germinate grain 420,000 left and right both can, protect into fringe 400,000 left and right.
Sowing width: as far as possible with 12 row sower wide-and narrow-row sowings, narrow row 12cm, wide row 18cm.Or with line-spacing planting with sowing machine such as 15 ㎝.
Sowing depth: face smooth soil property in field is carefully melted, seed level 3-5cm, broadcasts afterwards with the light earthing of wooden rake, in the whole overburden soils of seed, guarantees emergence rate.
3) prevent and kill off weeds in field
Every mu of use 2.5% chlortoluron 200-300g or 50% prometryn 75-100g after wheat cultivation, be watered 50 kilograms of earth's surface spraying (the every sprayer chlortoluron of knapsack sprayer 100g, prometryn 25-35g), after chlortoluron is watered, also can mix soil and spread fertilizer over the fields, prevent and kill off field broad leaved weed.Or wheat emerges three leaves wholeheartedly time, with sprayings such as 2.4D butyl ester, 2 first 4 chlorine, tribenuron-methyls (superstar).Tribenuron-methyl mu when 3-4 leaf, with doing outstanding agent 0.9-1.4g, is watered 30-50 kilograms of even spraying (the every sprayer 0.45-0.7g of knapsack sprayer, 30-80 grams of 2.4D butyl esters).
4) pour water
All one's life easily done speed decision frequency of irrigation because of soil water-retaining degree, Mian Gao depression, field gesture, weather temperature, evaporation discharge size, field face by wheat, plants single alternate spring wheat (being called for short single fringe wheat) peasant habit fill with a water in " May Day " left and right in Ningxia.
After the multiple fringe wheat breed that 1 year kind is two batches comes out, its breeding time is short, grows fast, emerge by the end of March, grow to three or four leaves about 20 days, this phase is also established the important period of wheat spike number just, rich water just becomes the key that obtains High-yield Wheat, and April 20 just can be filled with a water, and imposed fertilizer.
The second water will be filled with April 26-28; The 3rd water was filled with May 5-10; The 4th water and later each water are looked the dry wet situation of field face, Changes in weather situation, and the decision of wheat upgrowth situation, general wheat is filled with water left and right from emerging 6 times to maturation.
5) topdress
When nitrogen manure is sprinkled into field face and pours water after dissolving, week more than one, crop just absorbed utilization, when nitro phosphor complex is sprinkled into ground after filling with two or three water-soluble solutions, gradually absorbed by crops utilize time first quarter moon more than, wheat also grows to three leaves above and the long secondary root that starts to tiller, now must from soil, absorb enough desired nutritional elements could be early raw fast long, that is to say, could fine utilization after fertilizer six or seven leaves that three or four leaves chase after.Therefore, topdress and fill with a water and carry out simultaneously.Be that wheat 3-4 leaves are filled with a water and mu chases after 7.5 kilograms of 15 kilograms+diammonium phosphate of urea.Practice is found: first batch execute into fertilizer crop absorb completely, can continue to utilize for second batch of wheat, supplemented rapidly second batch and executed the gap fully not discharging into fertilizer efficiency.
6) pest control
In northern spring wheat district, wheat growth early stage (before booting) is because temperature is lower, insect pest is few, temperature rise (at the beginning of 6 months by the end of May) after booting, some insect pests spread as aphid, midge worm etc. starts harm, must " early, soon, resolutely " prevent and treat, effectively guarantee that nutrition and reproductive growth organ normally form, and are not encroached on.
Short for the general lasting period of current agricultural chemicals in the method for preventing and treating, the feature that drug effect is low, from wheat booting to maturation, at least prevent and treat three times, every minor tick 10-13 days, it is unit that pesticide dosage be take artificial knapsack sprayer (being filled with water 15 kilograms), convert for the first time the flolimat 100ml+ phoxim 100ml+ Avermectin 50ml+ aphid prestige (Aphox that goes out, Imidacloprid, pyridine worm miaow, black light lamp etc.) one bag, evenly be sprayed at Mai Zhushang, can not repeat to spray, second, convert for the third time flolimat 150ml+ phoxim 150ml+ Avermectin 100ml+ mite and stop A Wei rattle away 100ml(or other miticide farm chemical 100ml), even spraying.
7) harvesting
At wheat, enter wax ripeness latter stage, cauline leaf is yellow dry, wheat hardening, and just available wheat loses little grain header results, guarantees that Every grain should be sent to the granary.
2, second batch (summer sowing-autumn harvest)
1) wholelyly and basal dressing
The ground of planting second batch of wheat must be to pour water conveniently, and draining is unimpeded, and field face is smooth, the first-class arable land that field is less.After second batch of little wheat harvest, race against time, strive farming season, preferably utilize the time by 40 kgs/acre of disposable Tanakas of being sprinkled into of 40 kgs/acre+urea of ready two ammoniums, with rotovator, revolve 2-3 times, revolve dark 10cm left and right, a kind of farm tools is put down and is suppressed one time with stone roller is light.
2) sowing and line-spacing
With 12 row sower wide-and narrow-rows sowings, wide row 18cm, narrow row 12cm, seed level 3-5cm, or with line-spacing planting with sowing machine such as 15 ㎝, seeding quantity mu germinates and carries out by 420,000.Seeding quantity is calculated with following formula:
3) vernalization with emerge
After Wheat Species, speed is oozed ,Jiang field, field face with little water and is drenched and to be advisable, and must guard against broad irrigation, more can not field area water.Once have ponding to remove rapidly, in order to avoid the outstanding breath of seed anoxic goes rotten.Presoaking and germinating was emerged about 7 days.Wheat between the seeding stage field face all the time water keep moistening, can not dry hide, can not allow damp moisture in the soil expressed water.
4) pour water and topdress
Second batch of wheat in July to September, temperature is high, and field moisture content evaporation discharge is large.Wheat growth speed is fast, needs about 32 days from emerging to earing, and completes seedling stalwartness, organ builds up, determines spike number, tassel size and number of grain per ear at one month, the concentrated assault growth and development stage also heavily laying the foundation for fringe grain, and wheat is completely different from sowing in spring.Liquid manure is very crucial, water---fill with in time, diligent filling; Base manure---heavy dressing; Topdress---quick-acting (mu chases after 15-20 kilograms, urea), early chase after---about wheat three leaves.
When wheat growth will be seen day, sees ground, see soil moisture content and determine to the later irrigation period of 5 leaves and number of times.See it---rain and can not fill with; See that ground---earth's surface is dry and cracked will fill with; See soil moisture content---the ground that soil water-reataining fertilizer-keeping is good can be filled with less and easily be oozed easily dryly suitably fill with more.The frequency of irrigation of second batch of wheat is generally no less than seven water.
5) weeding and insect protected
Wheat 3-4 leaves, with 2.4-D butyl ester 30--80 gram, evenly spray wheatland, and emphasis is prevented and kill off broad leaved weed.Wheat eliminates aphis with flolimat 80ml+ phoxim 80ml+ Avermectin 30ml is anti-after emerging, and blackly touches worm, mythimna separata etc.During wheat growth, also to hold concurrently later and prevent and treat two spotted spider mite, the blue or green worm of Lay etc., control in general about 13 days once, wheat is no less than four or five times throughout one's life, the every sprayer of pesticide dosage: flolimat 150 ml+ phoxim 150 ml+ mites stop A Wei insect pest agricultural chemicals 100 ml such as 100 ml(or other control mite, spider that rattle away).
6) results
The wheat wax ripeness end of term, seed hardening, stalk leaf is also yellow dry, selects in time the grain header results that loss wheat is few.
