Specific implementation mode
Below in conjunction with attached drawing and embodiment, the present invention is described in detail, but not therefore by the protection model of the present invention It encloses and is limited among the range of embodiment description.
In conjunction with embodiment, the present invention is described in further detail, and the experimental method in following embodiments is as without especially Illustrate, is conventional method.
One, fresh edible maize is cultivated
Variety selection
The type of fresh edible maize is more and great variety of goods, to be eaten raw according to the purposive selection plantation of different purposes in plantation Corn variety.For example when for quick-frozen and canned sweet corn kernel processing, preferably select and reinforce corn or common Sweet corn variety, For grain color at foresythia, pericarp is soft after the processing of sweet corn of both types, and sugariness was both can be used when edible suitable for and with waxy The oily salt cooking also can cold and dressed with sauce salad.The kind applied in production at present, corn have Anhui sweet tea 210, Guangdong sweet tea 16, green superman, Wide sweet tea 5, Xin Meixiazhen etc., waxy corn have that Suyunuo No.5, Su Yu are No. 11 glutinous, capital section is glutinous 2000, wind is glutinous 2146, glutinous No. 5 of Anhui Deng bamboo shoot corn variety You Jing sections bamboo shoot 116, Shandong bamboo shoot jade No.1 etc..The present invention selects Anhui sweet tea 210, Suyunuo No.5 in experiment in cultivation Contrast experiment is carried out respectively with capital section 116 3 kinds of bamboo shoot.
Select soil
First, the plantation of fresh edible maize there are certain requirements planting site selection, and planting site preferably isolator or is partly isolated Space.
This is because the sweet tea of fresh edible maize, glutinous gene belong to the cryptic mutant of Endosperm Traits.When Sweety and waxy corn and commonly When corn or different types of fresh edible maize are mutually pollinated, Metaxenia is will produce, the contemporary seed tied is caused to lose It is sweet tea, waxy, become conventional corn quality.Therefore, be ensure fresh edible maize edible quality, when selection of land is planted, with it is other Type corn variety is strictly isolated, and quality is reduced to avoid because mutually going here and there powder.Partition method production on using space isolation and Time is isolated.Preferably the isolation of space.
(1) the spaces are isolated
It is required that other type corn varieties are not planted within the scope of 300~400 meters of growing area periphery, if any forest, hummock Etc. the natural cover for defenses, can suitably shorten isolation spacing.
(2) the times are isolated
If space isolation cannot be carried out, the method for time isolation (being staggered sowing time) should be taken to avoid and other kinds Flower synchronization, the interval time in sowing time of 2 different type corn varieties is generally 20~30 days.As large area is planted in flakes Corn can suitably reduce isolation standard.In short, not make two class zasiokaurins meet as principle.
Since fresh edible maize (especially super-sweet corn) general seed of seed is compared with flat, grain is small, germination, talent arch soil are emerged than general Logical corn seed is difficult, thus to select the soil is porous, fertile soil, the convenient plot of irrigation and drainage, fine site preparation.
Ploughing soil
20~30 centimetres are ploughed in time after preceding crop harvest, use sufficient base manure in conjunction with ploughing, generally organic fertilizer per acre 40 kilograms of 1000~1500 kilograms, 40~60 kilograms of composite fertilizer or corn fertilizer make base manure.Present inventor is by changing Become fertilization mode, fertilization mode by original Dressing ratios 5:5 are adjusted to Dressing ratios 6:4, i.e., 60 jin of base manure, top dressing are applied per acre 40 jin, and top dressing is carried out in the jointing stage, that is, completes top dressing in 25~30 days after emerging, hereafter no longer top dressing.
Plantation
After ploughing soil and fertilising, the plantation of corn is carried out.
The planting density arrangement of fresh edible maize will not only consider high yield requirement, it is often more important that consider its commodity value. Planting density is related with kind and purposes.According to breediness and sowing time, in medium fertility soil, plantation with 3500~ 6000 plants/acre are advisable, and spring sowing density wants smaller, and autumn sowing density will be more greatly.The planting density of early-maturing variety is more than late variety Planting density.
Equal line-spacings plantation, 60 centimetres of line-spacing are taken, or carries out 80~40 centimetres of size row plantations, depending on spacing in the rows is with density.
Interval sowing
Plantation fresh edible maize mainly sells fresh and tender fruit ear or supply factory process tinned food on the market, this and plantation Conventional corn is entirely different, meanwhile, it cannot be put long after fresh edible maize harvesting.Therefore, plantation fresh edible maize will be according to the need in market It measures and carries out interval sowing with the working ability of factory, order, generally sowed for 1 phase every 5 days or 10 days.Can sow in spring, Summer sowing and autumn sowing, and early, middle and late ripe variety matching extend the market supply time.
It sows in spring and 5 centimetres of ground temperature is required to stablize more than 10 (waxy corn)~12 DEG C (corn) earliest.Covering with ground sheeting then carries It sows within first 7~15 days.Alternatively, the measures such as presoaking and germinating or feeding block seedlings raising can also be used to sow ahead of time.
For such as Huanghuai Area, for example, Anhui Province can carry out mulching planting at the end of March or at the beginning of 4 months, can ahead of time on City.As long as date of seeding, can guarantee that pustulation period temperature can be harvested normally in 18 DEG C or more, fresh fringe at the latest for autumn planting.Sowing is too early, soil Temperature is low, and germination and emergence is slow, easily causes to be short of seedling for rotten kind.Per bunch planting kind 2~3, depth of planting is slightly more shallow than conventional corn, and general 3~4 Centimetre or so, timely earthing and fine smooth furrow face are answered after sowing.Rainy easily rotten kind of spring, the emergence of Drought in Autumn difficulty.Spring sowing is wanted Pay attention to dropping stain, autumn sowing will do a good job of it drought resisting.Furrow irrigation is taken, never flood irrigation, excludes field accumulated water after filling in time.
Field management
(1) thinnings, final singling:After emergence, seedling should be looked into time and filled the gaps with seedlings.The thinning when 3~4 leaves of seedling, when 5~6 leaves Final singling.Between final singling principle be except it is big, except it is small, stay centre, ensure full field seedling uniformity.
(2) the timely top dressings of are on the basis of using sufficient base manure, timely top dressing.Generally in 7~9 leaf of corn, urine is imposed per acre 20 kilograms or so of element, opens cave deep placement as possible.
(3) the row of filling, seedling stage of taking precautions against drought can suitably control water restraining the growth of seedlings in time, and soil moisture should be maintained at field capacity 60%~65%, after jointing, soil moisture should be maintained at the 75%~85% of field capacity.Meeting drought will water drought resisting in time. Rainy season pays attention to ditch cleaning, excludes field accumulated water.
(4) under the general weather conditions of supple-mentary pollination, corn can spontaneous pollination it is solid, but in special climate condition, such as In the case that continuous overcast and rainy or high temperature or plant growing way are weak, artificial supplementary pollination is needed.The artificial pollination time is generally in the morning 8:30 To 11:30 be Best Times.The cylinder that will pollinate gently is shaken against the filigree position that cuts off, be generally kept in 3 centimetres or so away from From not touching filigree, strainer avoided to be stained with water, pollen conglomeration also can manually be beaten with bamboo pole or rope pulls plant Top, to increase pollination amount.
(5) disease pest and weeds integrated control
The general cornfield weeding of control of weeds often selects the precious (soil of acetochlor ec (processing soil treatment agent), atrazine plus acetochlar, corn Earth processing and cauline leaf process dual-purpose) etc., carry out soil treatment before seedling after broadcasting, weeds after seedling can be handled, part is fresh with atrazine It is sensitive to atrazine to eat corn, cauline leaf spraying can be carried out with nicosulfuron or 2 first, 4 chlorine sodium salt.
Harvest in due course
Determine that suitable picking time is extremely important for fresh edible maize.The quality of fresh edible maize taste and quality, production The height of amount is also directly influenced by picking time except having outside the Pass with selected kind.It is in when the harvest corn of early spring sowing In summer high temperature period, grain filling rate is fast, terminates in a fortnight it is necessary to paying attention to observing kernel grouting often in corn pollination It is whether full, so as to timely collecting.In autumn low temperature period at a time when the harvest corn that summer and autumn are broadcast, grain filling rate is slow, harvest Period can suitably be elongated.
(1) the picking time of corns
Corn, which is generally 66%~71% (milk stage) harvesting in moisture content of kernels, to be advisable, in production practices, corn Harvest time its marketing quality and nutritional quality are influenced very big, cross early harvest, seed content is less, and mouthfeel is not very good; Too late, pericarp is hardened harvest, and dregs are more, and flavor reduces.The more difficult grasp of corn water content in harvest, and different cultivars, differently There is also differences between point, different sowing dates.In the present invention, the corn picking time of spring sowing is selected in after pollination 17~22 days, summer and autumn Being selected in 20~26 days for broadcasting harvests.If can early receive 1~2 day for the purpose of processed can;1 can be received in evening based on fresh fringe to sell ~2 days, 6 days or so picking time.In addition, sugar content declines rapidly after corn harvesting, therefore timely working process is wanted after harvesting.
(2) the picking time of waxy corns
Different kind the most suitable harvest dates have difference, are mainly determined by " food flavor ", be at milk heat end using fresh tes juice Or early dough stage harvesting.Waxy inadequate, the fresh fragrant and sweet taste of too late harvesting shortage, the only ability in the most suitable harvest date harvesting are harvested too early Show few tender seed, thin skin, dregs, savory sweet tea, in good taste.General pustulation period temperature of sowing in spring at 30 DEG C or so, picking time with It is advisable within 20~25 days after pollination, 20 DEG C or so of autumn sowing pustulation period temperature, picking time to be advisable after pollinating for 25~30 days.
(3) the picking time of bamboo shoot corn
It is multi-spike-type sweet-waxy maizes, effective fringe 3~6, it is therefore necessary to harvest by stages as bamboo shoot corn-.Harvesting it is suitable when Phase, just having gone out 1~2 centimetre of bract with the filigree of corn ear is advisable.Since pushing up fringe ,-secondary bamboo shoot were adopted every 1~2 day, 7~10 days Inside adopt.Adopting bamboo shoot must be timely, accomplishes stopped by neither wind or rain.When young corn harvests, it should be noted that adopt down bract simultaneously, prevent fringe bud from turning round It is curved, cause shredded bamboo shoot to fracture in bract.When going bract, filigree should be removed after bract has shelled since stem.Plant example and Mouthfeel is examined
The plantation that applicant carries out at Mengcheng County Ministry of Agriculture East China Crop cultivation observation experiment station is described below Experiment.Respectively choose three pieces of diverse geographic locations experimental field, wherein every piece of experimental field area be about it is 20 meters long it is x35 meters wide= 750m2(one mu of conjunction 667m2), split plot experiment as shown in Figure 5 is carried out, tri- cell modes according to the invention of A, B, C are applied fertilizer, D, tri- cells of E, F use conventional fertilizer application mode as a contrast, spacing distance 1-2 meters of test block and check plot;Between per cell Spacing distance is 1 meter;Wherein each cell sows 25 rows, and line-spacing is 0.6 meter, and spacing in the rows is 0.25 meter (4500 plants per acre), for examination Kind is respectively 116 3 Anhui sweet tea 210, Suyunuo No.5 and Jing Ke bamboo shoot kinds, 4500 plants/acre of thickness of sowing.It has been found that There are many factors that mouthfeel is influenced between the fresh edible maize of different cultivars, and the factor of chemical fertilizer being affected with Shi Zeshi it One.Applicant has summarized the experience a kind of rational chemical fertilizer with applying for the corn of above-mentioned different cultivars by field experiment and cultivation Ways and means, and then the mouthfeel and quality of fresh edible maize can be improved.Applicant combines new planting patterns and compares below The comparison example of traditional planting patterns come illustrate the present invention cultural method.
Example 1
Sweet tea 210 corn variety in Anhui is planted in first piece of experimental plot, is around planted non-corn variety and is excluded as isolation Hybridize disturbing factor, (Dressing ratios are adjusted to 6 to tri- cells of A, B, C on the basis of using sufficient base fertilizer:4) it, is imposed in its jointing stage N, 40 pounds/acre of P, K composite fertilizer, and by original Application Ratio 15:15:15 are adjusted to 15:10:20;D, tri- cells of E, F are still According to 15:15:15 are applied fertilizer as a contrast.
Male to taking out after hero in l0d to taking out in 210 corn growth of Anhui sweet tea, the present invention uses 2.5% biphosphate of foliage-spray 20 kilograms of potassium solution, and supplement 20 kilograms of 1% urea.It is separately sampled in grain filling period, the sugar content in determination sample seed, And the sample quality (result such as figure below) of two processing cells of control and adjustment fertilising is measured using near-infrared spectral analysis technology.
