Description
Technical field
The present invention relates to technical field of agricultural cultivation, and in particular to a kind of strong strain cultural method of corn full stand.
Background technique
Corn is the important cereal crops in China, forage crop and oil crops, crude fibre rich in, protein,
Fat, carbohydrate, vitamin and mineral element, nutritive value are high and widely used.
Corn is upland grain, but the time of infertility does not have enough moisture, it is difficult to normal growth, some because soil moisture content is insufficient,
Lack moisture, cause corn emergence rate low, therefore field soil moisture conservation seems extremely important, and each growth phase must also require
There is sufficient fertilizer nutrient, just can guarantee that maize sprout-promoting strengthens strain, otherwise will cause de- fertile early ageing phenomenon.It is formulated according to China various regions
Fertilising is studies have shown that 35% or less field crop nitrogen this season utilization rate, 20% or less phosphorus this season utilization rate, potassium this season utilization rate 50%
Below.Traditional planting patterns is generally spread fertilizer over the fields fertilizer in the soil and is ploughed, and fertilizer disperses in the soil, and part fertilizer is in soil
In lower leakage sink to the bottom, or be exposed at the manure digestion of earth's surface and scatter and disappear in air at gas, cannot be by corn so that part fertilizer loss
Plant root fully absorbs utilization, causes utilization rate of fertilizer low；In corn seeding season Chang Shaoyu, dry land periphery often because of water shortage not
Can be spread and sunk in filling in time, and large area ploughs the soil reclamation evaporation of water in soil, is unfavorable for corn seed and goes out full stand.
The straw-returning of Different Crop, it is seen that research report, but buried it is used as interlayer later period decomposed work in advance in dressing furrow
For having not been reported for granulated fertilizer.Layer by layer manuring, has an application on corn, wheat, soybean, peanut and other crops, but existing proposition
Layer by layer manuring is broadly divided into three kinds: first is that fertilizer layering is imposed on into the lower section of seed, though seed and fertilizer are separated, it is this
Fertilization mode is easy to the root of burn maize seedling, so that it is lost water suction or inhales the function of fertilizer；Second is that fertilizer cross stratification is applied
In the periphery of seed, although being separated by the distance of 5cm or more, this fertilization mode is also easy to injure jade because of fertilizer local concentration height
The root of meter Miao applies different number fertilizer point in same dressing furrow as seed manure, seed manure, jointing fertilizer, ear manuer and granulated fertilizer for five layers
Have not been reported；Third is that fertilizer is buried in layering of digging pit around seed, some holes are up big and down small, it is easy to cause fertilizer to scatter and disappear, fertilizer
Utilization rate is not still very high.Plastic-film-covered cultivation technology also has application on the crops such as peanut, corn, cotton, usually covers mulch
Cover the soil on ridge culture or the flat seed made, it is therefore an objective to which soil moisture conservation heats, and mulch is only covered on to fertilization area without cover-seeding

The invention has the following advantages that
1. moisturizing increases moisture in the soil, realize full stand: by seed pelleting conservation, the soil moisture conservation of plate stubble no-tillage seeding, sowing division when arid is applied
Fertile area's compacting soil forms capillary water absorption moisturizing, and fertilization area overlay film promotes temperature and sowing division under film and forms the temperature difference, so that moisture
It is spread from high-temperature region to low-temperature space, increases sowing division soil moisture content, when rainy weather, sowing division soil is easy water suction soil moisture conservation, is
Course of Corn Seed Germination emergence provides necessary moisture, promotes corn full stand.
2. improving fertilizer efficiency, realizes strong strain: being applied fertilizer by dressing furrow, fertilizer is concentrated, and fertilizer is avoided to be dispersed in soil, unfavorable
It is absorbed in corn root and reduces utilization rate of fertilizer；Dressing furrow bottom is equably embedded in by straw-returning, completely not rotten
Before change, as interlayer, the fertilizer in dressing furrow is separated with following soil, comparatively fast lower leakage after preventing fertilizer from melting；Pass through fertilising
Layer by layer manuring in ditch guarantees the necessary seed manure of corn, seed manure, jointing fertilizer, ear manuer and granulated fertilizer, realizes single-dose application, and corn is given birth to entirely
Educate phase utilization；Biodegradable mulch is covered by fertilization area, the soil layer of 2cm is covered on mulch, not only radix saposhnikoviae took off film, but also can prevent
The steam of evaporation sweats in film next part and rich water is made to concentrate in fertilization area being unfavorable for maize root system absorption, and overlay film makes fertilization area
Temperature be higher than the temperature of sowing division, the steam of evaporation gradually melts fertilizer in fertilization area, and rich water is just gradually to relative low temperature
Sowing division diffusion, and flowing to sowing division rich water is slowly to spread, so rich water concentration is relatively low will not to burn kind of a burn seedlings, favorably
It must be absorbed and utilized in corn root；Fertilization area and the sowing division shallow soil layer temperature difference under overlay film is obvious, and the temperature difference of deep soil layer is relatively not
Obviously, with the rising of seasonal temperature, the lower soil layer temperature difference is also being gradually increased, and realizes upper layer fertilizer first with after lower layer's fertilizer
It utilizes, meets the demand of each growth period of corn；When rainy weather, overlay film can protect fertilizer not to be flushed away lower leakage, and corn root
Portion's ground moistening promotes fertilizer to shift to root again, and by the above measure, fertilizer utilization is concentrated efficiently, realizes that strong sprout strengthens strain.
3. seed manure separates, prevent from burning kind: at a distance of 15cm or more, seed manure maintains an equal level with seed height to be omited for corn seed and dressing furrow
Decomposed chicken manure or farmyard manure that be low, and using, guarantee will not burn kind because of fertilizer Relatively centralized, because fertilization area rich water passes through temperature
Difference conduction diffusion, is slowly discharged into sowing division for fertilizer, burn seedlings will not occur.
4. layer by layer manuring prevents early ageing: the principle steady according to seed manure, seed manure is light, jointing fertilizer promotees, ear manuer weight, granulated fertilizer are mended, kind
Son protects out full stand, and seed manure applies decomposed organic fertilizer, and seedling stage because the root tender fertilizer requirement of children is few, gently applies urea, the jointing stage is nutrition
Vigorous period is grown, fertilizer requirement is larger, applies suitable urea, calcium superphosphate and potassium chloride, and boot stage fertilizer requirement is maximum, application
Slow-release fertilizer of carbamide and compound fertilizer, pustulation period fertilizer requirement is relatively fewer, and granulated fertilizer is using decomposed stalk as fertilizer；When seed is sprouted out
Miao Hou, seed just slowly send out roots must, sowing division not lid mulch, the gas permeability of soil is strong, more advantageous under the weather condition of arid
It must comparatively fast be grown in corn root, main root longest can grow to 15-20cm, and there are many more longer secondary root, layer by layer manuring is able to satisfy
The fertilizer demand of corn different growing stage solves the upper each growthdevelopmental stage of production and is unable to application in time and causes de- fertile early ageing
Problem.
5. stalk is degenerated, favorably loosen the soil: stalk is embedded in dressing furrow bottom, is isolated from the outside, and is conducive to stalk corruption degradation,
Urea promotes the speed of stalk corruption, the gas generated in the process, it will it is discharged by the stomata in soil, and fertilization area
Mulch is covered, gas will be discharged along the Soil Surrounding of mulch, be conducive to the loosing soil around corn root, without poison
Evil maize seedling.
6. density adds away from ventilation and penetrating light: compartment ditch is opened in north-south, and the sowing of embanked field north-south is conducive to using illumination, and corn is planted
The row and column of strain is all aligned, is conducive to plant illumination and ventilation, can fully utilize phosgene resource；In 2.3m furrow
Plant four rows between Tanaka, intermediate adjacent rows are away from 30cm, and intermediate other adjacent rows are away from 10cm, and two rows are respectively planted on both sides, line-spacing 10cm,
At a distance of 60cm, centre is the fertilization area of 30cm, every distance between rows and hills for the compartment ditch distance 20cm in Hang Yuqi, center row and both sides row
30cm, such sowing distance between rows and hills design rationally, can suitably increase plant density, per hectare reaches 90000 plants or more, energy
It is sufficiently used rich water resource, conducive to striving for high yield.
7. dart transfer is improved benefit: by plate stubble no-tillage seeding, Maize Seeds Coated diseases prevention, returning total stalks into fields is made
Fertilizer, fertilizer layering is disposable to apply dressing furrow, is conducive to dart transfer, protects environment, turn waste into wealth, after realizing that full stand strengthens strain
It is easy to strive for high yield, improve benefit.
8. compared with prior art, trench digging time, depth, shape, fertilization mode, fertilizer quantity and the kind in the present invention
Class, the mode of overlay film, the mechanism of action, type of seeding are all different.
