Description
Technical field
The invention belongs to the cultivation method of crops, refer in particular to the method that corn and soybean cooperate plantation.
Background technology
Since social development, scientific and technological progress, and living standards of the people improve, and have facilitated the whole society to the increase to the corn soybean demand.But because the quick growth of China's population, the continuous minimizing of arable area adds that corn and soybean yields fluctuate in recent years, so the imbalance between supply and demand meeting of corn and soybean is more and more outstanding.Predict that China's corn production-demand gap in 2010 will reach more than 2,301 ten thousand tons, solve the grain imbalance between supply and demand, will increase grain yield beyond doubt, and China's arable area is limited at present, by enlarging kind of grain area possibility hardly, utilize well stimulations such as chemical fertilizer, agricultural chemicals also not have what potentiality.Feasible is exactly the yield potential of bringing into play high yielding variety, and the culture technique of no-float is created superior crop growth environment, increases substantially the grain per unit area yield, increases gross yield, could satisfy the demand of the whole society.
The production Tanaka of crops, a general phenomenon is arranged, look in the crops that is exactly edge of a field rand, the output height.Big as corn ear, grain is many, and output is outstanding.Soybean is born pods many, full seed, and output is obviously high.This phenomenon people are called " limit row advantage ".Chasing after its reason, mainly is that the ventilation and penetrating light condition is good.Enlightenment wants further to improve crop yield thus, will create good ventilation and penetrating light condition for crop growth, improves utility rate of luminous energy, gives full play to the yield potential of crop, makes grain yield that a new breakthrough be arranged.Study according to scientist, the output of crops accumulates by photosynthesis more than 90%, plant is in the photosynthesis process, and the luminous energy that utilizes the sun is carbonic acid gas and the synthetic organic substance of aquation carbohydrate by chlorophyllous effect---grain just.; corn is 20%-28% to the theoretical value that solar energy utilizes; in agricultural production practice; sunlight can not be entirely maize leaf and absorb; remove the most of luminous energy of " return and penetrate " " scattering " " leakage is penetrated "; the practical efficiency that general land for growing field crops produces glazing has only 0.4-1%, and the highest have only 4-5%, also has very big potentiality so further improve utility rate of luminous energy.Production practices prove, improve the fundamental way of utility rate of luminous energy, the one, select high light efficiency kind, and the 2nd, create good ventilation and penetrating light environment.
Select the high light efficiency corn hybrid seed of compact for use;
According to a large amount of scientific experimentation results and production practices, select the corn hybrid seed of the high light efficiency of anti-dense planting of compact for use, be to realize the corn with high yield effective way of high yield again.Along with popularizing of advanced practice of agronomy, flat-type thin planting corn variety can not meet the needs of production, particularly soil property is fertile, rainfall is regional plentifully, increase along with planting density, empty stalk, lodging, susceptible seriously take place in the flat-type corn variety, have become the limiting factor of present corn unit yield.The density of China's field corn is lower than external corn main producing region, and this is a key factor of restriction China corn yield.In order further to improve grain yield, select for use the high light efficiency corn variety of anti-dense planting of compact imperative.High yield form and the physilogical characteristics of compact corn crossbreed are:
1, the leaf angle is little, and leaf is big to value.The leaf angle is decision colony's printing opacity and the important indicator that is subjected to the light attitude, blade and stem stalk angle are little, the strong upper punch of blade then is described, help the middle and lower part blade and be subjected to light, compact corn fruit ear upper leaf angle is 22.55 °, the lower blade angle is 38.45 °, average 23.14 ° of complete stool, and the leaf angle of flat-type is 33.76 °; Leaf is expression blade and cane corner dimension and the blade overall target in the space degree of sag to value, and leaf is big more to being worth, and shows that blade gets over upper punch, and the luminous energy of intercepting and capturing is many more.The compact corn leaf is to 36.81 ° of value complete stool average out to, and flat-type corn complete stool leaf is to average 28.1 ° of value.
2, leaf area distributes rationally, and leaf area index is big.The above leaf area in compact corn fringe position accounts for 45.2% of the total leaf area of complete stool, the following leaf area in fringe position accounts for 54.8% of complete stool, and the above leaf area in flat-type corncob position accounts for 62.7% of complete stool leaf area, the following leaf area in fringe position accounts for 37.3%, the above leaf area in compact corn fringe position is less, this distribution is very favourable to increasing colony's light transmittance, the compact corn kind is when leaf area index reaches 5.15-5.25, place, fringe position light transmittance is 38%-37.6%, and flat-type has only 30.1%.Because blade distributes rationally, the field illumination condition is improved, make compact corn solved to a certain extent flat-type kind leaf area index improve with rate of photosynthesis yield decline between contradiction.Studies show that in a large number the maximum leaf area index of flat-type corn variety high-yield culturing is 3.5-4.0, surpass the closing of 4.0 strain clumps, ventilation and penetrating light is bad, and the yellow leaf of base portion is many, and the stem stalk is thin and delicate, empty stalk, bald increase, and output descends.And the effective maximum leaf area index of compact kind high-yield culturing can reach 5.0-7.0, still can remain on 3.0-3.5 when maturation.The increase of leaf area index shows the increase of photosynthetic area, and the breakthrough of leaf area index is the important physiological foundation of compact corn kind high yield.
3, photosynthetic gesture is big, the economic coefficient height.Corn yield depends primarily on the photosynthetic gesture and the economic coefficient of colony.Green blade carries out photosynthesis and forms output depending on two factors, the one, the working time of blade, the 2nd, the operating efficiency of blade, photosynthetic gesture is represented the photosynthetic fate that leaf area is carried out of a colony, with square metre the day/hectare represents.So in the certain hour scope, photosynthetic gesture is bigger, the population photosynthesis time is long, and dry-matter accumulation is many, and output is also high more.According to test, compact corn kind gross photosynthesis gesture be 3,500,000 square metres day hectare, flat-type corn variety gross photosynthesis gesture be 2,500,000 square metres day hectare.Economic coefficient is meant that economic flow rate accounts for the ratio of dry substance mixture.Facts have proved that compact corn crossbreed economic coefficient generally is 0.5-0.55, and the flat-type corn hybrid seed generally is 0.4-0.45.Confirm that according to research of agricultural science economic coefficient increases by 1.0, output is minimum to increase by 20%.
4, net assimilation rate height, dry-matter accumulation is many.Net assimilation rate is meant the dry matter that leaf photosynthesis is produced, the clean accumulation behind the deduction respiration consumption.7.79 gram/(square metre days) of compact corn net assimilation rate, and the flat-type corn was 5.33 gram/(square metre days).
5, chlorophyll content height.The chlorophyll content of compact corn and photosynthetic intensity, the degree that reduces with the increase of density is significantly less than the flat-type corn.This is that the compact corn growth is fast, and the later stage filling speed is fast, dry substance accumulation speed height, the internal factor that grain yield is high.According to surveying and determination, the compact corn chlorophyll content is higher by 13.7% than flat-type, and light and intensity are high by 27.06%.
Have at present and adopt corn and soybean to carry out intercropping in 2 * 2 ratios, shortcoming is: output improves not obvious.
Summary of the invention
The invention provides a kind of double high-yield maize penetrating planting method, output improves unconspicuous problem when solving present corn and soybean intercropping.The technical scheme that the present invention takes is: comprise choosing ground, whole ground, choose seeds, begin sowing in good time, field management, results, it is characterized in that:
A, choosing ground: grow up in 100 meters to, ridge in the thing ridge, and the ridge number is greater than 30 ridges, 60～65 centimetres of distance between the ridges;
B, whole ground: thaw 15 centimetres of the degree of depth of soil, carry out three in the plot of removing the root stubble and plough into the ridge, in conjunction with deep placement base fertilizer, 10～30 centimetres of the degree of depth with beating the ridge with suppression, reach state to be broadcast;
C, seed selection:
Corn is selected high light efficiency kind of the anti-dense planting of compact and thin planting large-spike cultivar for use;
Soybean is selected anti-loose plant for use;
D, begin sowing in good time: when 5-10 centimetre of topsoil, ground temperature is stable by 10 ℃, soil moisture content 18%～22% o'clock, and sowing corn earlier, soybean is later than corn sowing in 7～10 days; Type of seeding is corn kind four ridges, and wherein two limit row are sowed thin planting large spike corn varieties, and this thin planting corn hole is apart from 50 centimetres, every hole 3 strains, the high light efficiency kind of the middle two rows sowing anti-dense planting of compact, this dense planting corn hole is apart from 40 centimetres, the two strains of every hole, adjacent these corn kind soybean four ridges, four ridges all are anti-loose plant, and this soybean hole is apart from 50 centimetres, the two strains of every hole, plantation thin planting large spike corn in the furrow in the middle of this four ridges soybean, 50 centimetres of this thin planting type corn hole distances, every hole 3 strains; Or corn kind six ridges, wherein two limit row are sowed thin planting large spike corn varieties, and this thin planting corn hole is apart from 50 centimetres, every hole 3 strains, the high light efficiency kind of the middle four lines sowing anti-dense planting of compact, this dense planting corn hole is apart from 40 centimetres, the two strains of every hole, adjacent these corn kind soybean six ridges, six ridges all are anti-loose plant, and this soybean hole is apart from 50 centimetres, the two strains of every hole, plantation thin planting large spike corn in the furrow in the middle of this six ridges soybean, 50 centimetres of this thin planting type corn hole distances, every hole 3 strains.
Among the present invention, the high light efficiency kind of the anti-dense planting of corn compact is selected Zheng Dan 958 or lucky single 209, and the thin planting large-spike cultivar is selected greenly to educate 9911 or greenly educate 9915, and TOLERANCE OF SOYBEAN thin planting kind is selected lucky new beans for use No. one.
Technical characterstic of the present invention is:
1, preferred kind is the internal cause of high yield.Production practices prove, select best high yielding variety for use, can give full play to the yield potential of high yielding variety.The high yielding variety of the anti-dense planting of corn, as Zheng Dan 958, the thin planting large-spike cultivar educates 9911 as green, greenly educates 9915, and soybean is selected the lucky new beans of anti-thin planting for use No. one.
2, increase density, structure high yield colony are the keys of high yield.Corn and soybean are that only guaranteed density just can be achieved higher output by colony's volume increase.Corn is kept a full stand of seedings for half hectare can not be less than 5.3 ten thousand strains, and half hectare of soybean kept a full stand of seedings can not be less than 30,000 strains.
3, scientic planting is the condition of high yield.Facts have proved that field ventilation and penetrating light condition is good, crop utility rate of luminous energy height, photosynthesis strengthens, and is the essential condition of high crop yield.In the field is that good ventilation and penetrating light environment is created in plant growth, vertically height Different Crop intercropping, and horizontal expansion hole distance reaches crisscross ventilation and penetrating light like this, gives full play to limit row advantage, increases substantially crop yield.
4, chiselling earth is the basis of high yield.Chiselling earth is that root growth and development is created a good soil environment, strengthens the vigor of root system, enlarges the scope of activities of crop root, guarantees the absorption and the running of nutriment, promotes the stalwartness growth of acrial part, and well established and vigorously developing is the basis of high yield.
The invention has the advantages that:
1, number of plants per unit area increases.Corn and soybean are planted by three-dimensional penetrating mode, and the strain density of taking to contract, and expand hole apart from adding measure such as strain, but more than maize planting 53000 strains on half hectare of area, are equivalent to plant clearly one hectare strain number.Add half hectare of soybean area, one hectare becomes one and half area.
2, utility rate of luminous energy improves.The different two kinds of crop-plantings of height are on same area, height has formed the corridor of ventilation and penetrating light, intercropping has embodied the mutual supplement with each other's advantages of two kinds of crops, the short bar happiness of soybean is cloudy, the high bar happiness of corn sun, the solid growth of just arranging in pairs or groups makes full use of luminous energy, utilize the two " space parallax " that forms in process of production, " time difference " to bring into play the productive potential of limited agricultural resourcess such as light, fertilizer, water, gas, heat effectively, remedy the deficiency of nonoculture.It is that solid is subjected to light that the rice beans intercropping face of flattening is subjected to light, has increased light-receiving area, and maize intercropping side light income obviously increases, thereby has prolonged the photosynthetic time of corn, has increased the synthetic and accumulation of photosynthetic product.Measure according to Beijing agricultural university, the intercropping of rice beans, the average transmittance that corn is capable improves 10-20% than nonoculture, and effectively light application time increases by 9.9%.The intercropping of rice beans, two kinds of complexs that the crop collocation forms, its density and leaf area index surpass the restriction of nonoculture, measure according to the study, and the maximum leaf area index of nonoculture corn is 4.45, and the maximum leaf area index of intercropping can surpass 5.14.Measure according to the study, corn is under the nonoculture condition, afternoon carbonic acid gas for the moment is 70% o'clock of constant, if do not ventilate, one minute can be with carbon dioxide-depleted on every side, in general, gas concentration lwevel drops to 80% o'clock of constant, photosynthesis obviously descends, as drops at 50% o'clock, and photosynthesis is near halted state.Maize intercropping plot wind speed than the high 2-4 of nonoculture doubly, thereby improve intragroup carbonic acid gas supply, improve photosynthetic intensity, increase crop yield.
3, row advantage in limit strengthens.As the intercropping in 4: 4 of corn and soybean, the soybean furrow increases delegation's corn again, and in 5 row corns 3 row being arranged is limit row, accounts for 60% of corn line number.The wind printing opacity is good and the root system absorption region is big advantage improves output to utilize the limit to work.Row in the middle of row living power in corn limit is significantly higher than, limit first row doubles than nonoculture, and second and third row is than the high 20-40% of nonoculture, and when above above 6 row, effect of increasing production is not obvious.
4, underground factor and the complementation of crop adaptability.Maize root system distributed depth and soybean root are roughly the same deeply, but the dense layer difference, the intensive degree of depth of corn root mass is in the 40-55 centimetre, and the soybean dense layer is in the 20-30 centimetre.With two kinds of crop interplantings, but layering utilizes nutrient and moisture, spatially demonstrates complementary phenomenon.Legume crop can need nitrogen few by the nitrogen in its symbiotic nitrogen-fixing bacteria fixed air relatively, and needs phosphorus potassium many, and corn needs nitrogen, phosphorus, silicon many, will need the fertile crop different with the fertile characteristics of suction to arrange in pairs or groups productions in and plant, the complementary phenomenon of demonstration on nutrient.The field microclimate that superior adaptation soybean produces is built in intercropping, and the corn plant height has formed the wind-break in soybean field, has reduced the evaporation of moisture, and the big light radiation power of air humidity is strong, favourable soybean growth.The damage by disease and insect that two kinds of crops are had nothing in common with each other and to boisterous adaptive response.In general, the contend with ability of natural calamity of nonoculture is on the low side, and intercropping utilizes different resistance of crop and adaptive faculty, disaster mitigation loss to greatest extent.
5, invalid fringe reduces, and ripening rate improves.The corn different cultivars is carried out reasonable intercropping, prolongs to be pollinated the phase, improves ripening rate, and two kinds are pollinated mutually, and can improve grain quality, and the commercial grade of grain is improved.In recent years, owing to reasons such as weather and improper fertilizations, invalid small ear phenomenon appearred in a hole individual plant Maize Production field 80%, and corn is by the many strain plantations of a hole, and a fringe is only tied in a strain basically, greatly reduces the generation of invalid small ear.According to another Hebei Prov. Academy of Agricultural ﹠. Forest Sciences's research conclusion, corn hybridization can increase production more than 5% the present age.
6, efficent rotation increases fertility of land.As corn: the intercropping in 4: 4 of soybean, can carry out efficent rotation next year, concerning other crops, soybean root system is the system of taproot, and it is darker to bury, can chesson, and length has root nodule on root, and free nitrogen in the energy fixed air is except that itself needs, also be retained in a part of nitrogen in the soil, supply with succession crop and utilize.Measure according to the study, the soybean stubble can be a back batch nitrogen that stays and is equivalent to 326 jin of urea.According to Jilin Province's investigation, regional northeastward, soybean stubble kind corn can increase production more than 18%.
By 24000 jin of the highest average yield per hectares of Jilin Province maize, corn 0.56 yuan of calculating per jin, 13440 yuan of average per hectare incomes.Adopt economic benefit of the present invention, plant by 4: 4 ridges with corn and soybean, 18763 yuan of average per hectare incomes are overcharged into 5323 yuan than corn nonoculture.If by 7%, 19.25 ten thousand hectare of 2,750,000 hectares of the whole province's corn areas, promote this agrotechnique, the corn soybean area is 1: 1, and the soybean area also is 19.25 ten thousand hectares, totally 38.5 ten thousand hectares, increases income 20.5 hundred million yuan altogether.So the present invention is less investment, the novel species method for planting that brings notable results is increasing peasant income, growth of agricultural efficiency, and rural economy strengthens, and accelerates the rural area and realizes well-off society's paces, will bring into play certain positive role.
