Step 2, corn machine are live.
(1) the resistance to close anti-fall improved seeds of compact high yield are selected
According to Anhui Province sandy loess summer corn main producing region natural ecological condition, selection high and stable yield is good, resistance to close The strong superior corn kind of lodging resistance.Such as grand flat 206, step on sea 605, Zheng Dan 958, first jade 335, middle list 909, calabash shell serving as a dipper jade 35, dredge list 20th, the kind such as big section 702, Shandong single 981, middle section 4, peace agriculture 9
(2) seed quality and seed pelleting are improved
On the basis of from improved seeds, high quality seed is selected, particularly requires that percentage of seedgermination >=95% is (minimum also Reach more than 92%), while being necessary for capsuled seed.
(3) straw full dose mechanical crushing throwing returning
During harvesting wheat, the combined wheat harvester of polishing apparatus is crushed and cut with stalk from high-power, wheat toothing is high Degree≤25cm, wheat stalk crushes length≤15cm, and the wheat stalk after crushing will be shed uniformly, should not be into ridge or heap in heaps Put.If stalk amount is excessive, or toothing is too high and straw scattering draught is uneven, must before broadcasting with stubble-cleaning machinery carry out stubble-cleaning, then Sow again (such as Fig. 2).
(4) sowing is concentrated when losing no time in sowing while there is sufficient moisture in the soil
Adhere to that " summer sowing is without early, more early better;Catch an early word, prominent one is robbed word " principle.Preceding stubble harvesting wheat Summer corn is sowed when losing no time in sowing while there is sufficient moisture in the soil as early as possible afterwards, sowing is concentrated before striving June 15 to reduce bud flood and nurturing staff.If soil moisture in the soil Feelings are not enough, broadcast summer corn to rob and also can first sow, teeming " cover-head water " in time after broadcasting.
(5) rational close planting, patch stubble simple grain machine is live
Length is crushed according to plot flatness, stalk and the uniformity and machine power is shed from 2~4 row simple grain planters Patch stubble sowing is carried out, line-spacing, spacing in the rows 24cm~26cm, 4500 plants~5000 plants/acre plantations (such as Fig. 3) are waited using 60 centimetres.Really Protect seeding quality, it is ensured that 3~5 centimetres of depth of planting and uniformity.Density of reserved seedlings should ensure that at 4500 plants every mu or so, resistance to close The good kind planting density of property can be properly increased.With the density amount of broadcasting surely, the seed grain number of sowing should suitably stay Miao Mi than determination Degree increase by 15% or so.
Step 3, foot fertilising material, chemical fertilizer mechanical deep fertilizing.
Using soil measurement formula balance fertilizing, under the premise of wheat stalk total crop return based on nitrogen fertilizer application, coordinate a fixed number The phosphorus potash fertilizer of amount, and add appropriate micro- fertilizer.Seed manure will be separated with seed, be prevented " burn and plant ".
Fertilizer application requirement:Under the conditions of the fertility straw directly returning to field of medium soil, 600kg/ mus of corn productions are realized The dose of amount is:Purity nitrogen 16-18kg, P2O5 6-8kg、K2O 6-8kg.Fertilizing method is taken to be carried out by several times by stages.
(1) base manure:Using 50 kilograms of NPK (N-P-K=15-15-15) and 10 kilograms or so of urea or (N-P- 50 kilograms of the high nitrogen of K=25-10-10), separately buried simultaneously with seed simultaneously in sowing from no-tillage fertilizing and seeding machine.
(2) topdress:After planting every mu imposes 10 kilograms or so of urea, machine to toy trumpet mouthful phase 25d~30d, i.e. jointing stage Tool side deep placement (cm of depth 10);Boot stage is after planting 45d or so, application urea 10kg~15kg, or after planting 40d~45d, i.e. typhon mouthfuls of phases apply urea 15kg~20kg;Flower period can add urea 5~10 in right amount according to plant growing way Kilogram or so.Such as use the fertilization mode of disposable bottom application, it is necessary to select sustained slow-release fertilizer.
Step 4, water management requirement:Drought and waterlogging is prevented, in time the row of filling
The insemination and emergence phase will ensure good soil moisture content.Soil moisture content is not enough when such as sowing, and timely teeming " is covered after broadcasting Head water ", it is ensured that one broadcasts full stand.Because damage or crop failure caused by waterlogging, stain evil easily occur for seedling stage, field Yao Gou should be dredged, ditch, furrow ditch is enclosed, accomplish " three Ditch " is supporting, prevents seedling stage flooded stain.In case of storm water wants timely draining, anti-bud flood and seedling flood.Booting and filling stage is needed to moisture The amount of asking is big, and meeting drought should irrigate in time.
After planting or before and after jointing, interlacing trench digging, in case irrigation and drainage, preferential defense seedling stage stain does harm to, utilizes row when watering The irrigation ditch interlacing that inside begins to rehearse is watered;Male preceding 10d, rear 20d are taken out, field capacity should be kept 75%~80%, water deficient will be every Row waters;Field has ponding to want timely draining.
Sowing and strong sprout under the conditions of step 5, straw-returning.Corn uses no-tillage and direct-seeding technology, it is ensured that sowing is uniform, seed level Unanimously, do not replay, not broadcast leakage;In the ranks distance and depth of planting need to be adjusted according to crop varieties, planting density.And this hair Bright to have promoted " three are adhered to " and " five suitable sowings " nurturing staff technology first, this technology is to realize that maize sprout-promoting, drought resisting are protected The key technology of seedling, the strong big fringe of stalk and later stage anti-early ageing.Adhere to straw chopping and returning, applying organic manure and use sufficient base manure;It is hard Hold that high-power machinery essence amount is even to be broadcast and five suitable (suitable moisture in the soil, optimum period, appropriate, suitable formula, suitable deep) sowing;Adhere to that seed pelleting or medicament are mixed Plant soil chemicals treatment." three are adhered to " is to realize that seedling is complete, Miao Qi, the uniform seedling of seedling are strengthened, it is ensured that maize sprout-promoting and realize that strong stalk is big The essential technique (such as Fig. 3) of fringe.
Speed corruption is preserved soil moisture and irrigated under the conditions of step 6, straw-returning.To be watered in good time after broadcasting, soil moisture content is reached field Between water-holding capacity 75%-85%, to accelerate soil to sink reality and straw decomposition, it is to avoid straw-returning is emerged and late growing stage to crop Influence.
Maize field crop smothering integrated control under the conditions of step 7, straw-returning.
Prevention and control of weeds:Rear before seedling is broadcast, when soil moisture content is suitable or has been poured after " cover-head water ", with 40% atrazine plus acetochlar or 48% The herbicides such as beautiful grass spirit, 50% Acetochlor, to carrying out closing weeding after water.Also can be beautiful with 48% in the corn visible leaf phase of leaf 3~5 The herbicide after seedling such as careless spirit or 4% beautiful agriculture pleasure, bud are defended, nicosulfuron, atrazine spray to being oriented after water on corn inter-row weed Mist.Accomplish not respray, not drain spray, and note drug safety, prevent herbicide damage.
Step 8, complete ripeness harvest
Into after September part, bracteal leaf of corn turns yellow successively, and seed top is gradually hardened, and many peasant households take for maturation, just Start harvest.It is only now actually ripe beginning, first quarter moon or so is also needed from real maturation.Corn appropriate evening receives, and can make The nutrient remained in stalk continues to convey into seed, gives full play to afterripening, increases yield, improves quality, improving quality. Corn complete ripeness harvest technology, which is one, need not increase the yield-increasing technology of any input.Corn after pollination 40 days to before complete ripeness, Receive 1 day every night, every mu can increase production 5 kilograms of corns.Postpone ten days and receiving, every mu buys hundred jin of grains more.
(1) strictly holds the full ripe mark of corn
The mark of corn kernel physiological maturity mainly has two, and one is that seed base portion black layer occurs;Two be that seed milk-line disappears Lose.30 days or so after corn pollination, the endosperm tissue at the top of seed starts hardening, with bottom succulence endosperm fraction formation one laterally Boundary layer is milk-line.50 days or so after pollination, fruit ear bottom seed milk-line disappears, and moisture content of kernels drops to less than 30%.Corn Full ripe stage blade turn yellow, fruit ear bract be dried, it is fluffy, it is white.Seed is integrally hardened, and the intrinsic grain type of this kind is presented And color;Corn kernel milk-line disappears.Corn ear is broken disconnected from centre, the boundary line either with or without yellow-white in the middle of seed is seen, if There is corn to be in dough stage, if without being only full ripe stage;There is black layer in corn kernel.After corn kernel is taken off, seed bottom Bennet remove, if there is black layer, represent ripe.The general volume increase 10% or so of full ripe stage harvest.
(2) summer corns complete ripeness water content in harvest
Huainan, general in late September complete ripeness along the regional summer corn in Huaihe River, northern territory summer corn will typically arrive October by the end of September First corn ability full maturity.Therefore to change 40~45 days harvests after customary corn pollination to harvest for 55 days after pollination.Together When to widely popularize mechanical harvest and straw chopping and returning integrated technique.
1. manually break after fringe harvest, then stalk machinery returning to the field utilizes straw counters-field set using manually corncob is taken Directly by straw chopping and returning.This technology is more ripe, lacks harvest stubble-cleaning machinery area and generally uses.
2. mechanical harvesting or threshing, stalk crushes combining fruit ear harvest and straw chopping and returning integration of operation, once Complete harvesting, fruit cluster delivering, header, straw chopping and returning flow chart.No matter adopting which kind of harvesting approach will be according to corn Lodging degree, planting density, and corncob sag, minimum knot fringe height situations such as, carry out mechanical debugging, made with sharp field Industry.Corn combine harvest be adapted to wait line-spacing, minimum knot fringe highly 35 centimetres, lodging degree<5%th, the sagging rate of fruit ear< 15% plot operation.Corn kernel moisture content is higher (30%~40%) during China's Huang-Huai-Hai most area harvest, corn Harvest machinery operation only completes the operations such as harvesting, header and straw-returning, not direct threshing.China's harvest corn optimum period, is because of product Kind, date of seeding and area and it is different, more in wax ripeness latter stage.It if being done directly threshing operations, need to postpone harvest time, make corn de- in field Water is to water content 25% or so.Corn mechanical harvest requires grain loss rate≤2%, fruit ear loss late≤3%, seed damage rate ≤ 1%, bract walnut hulling rate >=85%, fruit ear percentage of impurity≤3%;The height for the stubble left (type with straw-returning operation)≤10 lis Rice, returning to the field straw chopping qualification rate >=85%.
3. dry in time, the fruit ear and seed after the harvest corn that prevents from going mouldy focus on behind threshing ground and to dry or divulge information in time Precipitation, what the smaller stacking in place was relatively concentrated overturned 1 time every several days, prevented that sealing heap goes mouldy.
Fringe is store:Wall can be done with iron wire, brick, sorghum, plank, be covered with thin iron, asbestos shingle, build up permanent granary.
Grain storage:Before seed puts in storage, using gravity-flow ventilation and natural low temperature, Grain water is down within 14%.
3. straw chopping and returning technical parameter and technical essential
(1) stalk crushes Wheat Straw and crushes mulching and returning Mechanization Technique quality index:Stubble height≤25cm, Wheat Straw The qualified chopping length≤15cm of stalk, stalk crushes length qualification rate >=85%, and rate≤20% is cut in crop residue cover rate >=40%, leakage, Straw scattering draught unevenness≤20%.Corn seeding depth 2.5cm~4.5cm, seed manure imposes on 3cm~5cm below seed, earthing Tight, seed percentage of damage≤0.5% of suppression, hole rate≤3%, field is without broadcast leakage, and the edge of a field is without replay.
(2) irrigate and fit soil moisture content and rain condition after broadcasting and irrigate one time, supplement irrigation promote stalk rot and seed and soil contiguity to prevent Only Drought at seedling stage.
(3) cultivation fertilizing method is taken is carried out by several times by stages.Suppress or spray after broadcasting, moisture in the soil is mended in furrow irrigation;Promote capsuled seed and Dressing seed technology, timely anti-subterranean pest-insect and seedling stage insect;Straw mulching and returning wants timely after seedling cauline leaf to eliminate.In sowing Afterwards or before and after jointing, interlacing trench digging, in case irrigation and drainage, preferential defense seedling stage stain evil, utilize the irrigation ditch interlacing that begun to rehearse in row when watering Water;Male preceding 10d, rear 20d are taken out, field capacity should be kept 75%~80%, water deficient wants interlacing to water;There is product in field Water wants timely draining.
The kind and selection of time of fertilising are particularly important, must be based on nitrogenous fertilizer, because the straw of preceding crop Nitrogen in stalk decomposition and consumption soil, can prevent succession crop weak seedling and Huang Miao based on nitrogenous fertilizer.

Embodiment 3
Huang-Huai-Hai, especially Anhui Province, a main underproduction factor of summer corn are that the water drainage problem in rainy season. In order to drain flooded fields, the present invention carries out draining after corn seed by the way of interlacing trench digging.The purpose of water drainage is to ensure then Yield, but water drainage while can bring a long-range problem, be exactly soil erosion, now plant landlord typically primarily focus on Current production, and soil erosion has been ignored.This soil erosion occurs especially in slope, area especially with heavy rainfall Slope, corn planting is in order to ensure draining smoothly, many planting patterns using along slope into ridge.This planting patterns water drainage Easily, but because current are excessively smooth it is easily caused soil erosion.Present planting patterns, the cleaning of corn bottom weeds Thoroughly, the soil without vegetation protection easily produces a large amount of losses of water and soil after by rain drop erosion.
In order to solve the problems, such as this soil erosion in hillside fields, the application is proposed first oblique opens longitudinal furrow+ditch into ridge+interlacing Open the comprehensive solution of traverse furrow in interior press-in stalk+bottom.
In the present embodiment, to stalk shed and planting process is adjusted.Specifically, first, in straw scattering draught When, reserved part wheat stalk, it is highly preferred that reserved part autumn the previous year harvest maize straw (have many areas due to Condition of storage and limited in one's ability, stalk be difficult to retain to summer corn plant when, it is this to use wheat stalk), maize straw Blade is thick to be more beneficial for shield soil.
During corn planting, using along along the oblique planting patterns into ridge in hillside fields, i.e. planting process, direction and the gradient side on ridge To forming an angle, such as 30-80 degree, the selection of the angle is empirically determined based on annual precipitation.After plantation, Or in planting process, longitudinal furrow is opened in interlacing, stalk is shed along longitudinal furrow direction in longitudinal furrow, by V-type pressure roller to shedding after it is vertical Ditch is compacted.What stalk here crushed that size is greater than normal straw-returning sheds size, is advisable with 4-6 cuns.
Bottom in hillside fields, on ridge, head excavates transverse drain ditch, keeps certain slope, transverse drain ditch is wider than longitudinal drainage Ditch, it is conditional that ditch inside is compacted using machinery, further prevent erosion.
When the fore-and-aft distance in hillside fields is larger (when referring to that slope pushes up longer to bottom of slope from slope), every a segment distance, adjustment The trend on ridge so that ridge above slope and between the ridge of lower section it is reciprocal in zigzag.This can ensure the same of water content When, in the case where rainwater is excessive, it is to avoid because large area lodges caused by ponding and water impact.If in addition, using Z-shaped Shape cloth ridge, then transverse drain ditch is also in accordingly zigzag, and deeper traverse furrow is exactly to prevent draining difficulty when rainfall is larger and design 's.
We have carried out the contrast experiment of 3 years in two parts of the plot of Mengcheng County respectively, in first piece of experimental plot On, applicant according to embodiment 1 planting patterns.On second piece of experimental plot, using the planting patterns of the present embodiment.
Then, after corn planting, in rainy season respectively to the furrow draining flowed out on two pieces of experimental plots in containing sand Amount is tested, and the test result of 3 years, which is compared, to be found, using the planting patterns of the present embodiment, and silt content is than implementing in current The low 25-50% of example 1.
Moreover, applicant has been surprisingly found that, using the planting patterns of the present embodiment, the growth of weeds is also inhibited, because This, it is possible to reduce the usage amount of herbicide.Actually straw-returning technology be initial stage in returning to the field it is ineffective to corn growth, because This, existing returning to the field mode can just cause the underproduction, therefore, and it is also unfavorable to weed growth, and in the present embodiment, be thrown at furrow Stalk is spread, and is compacted, at the furrow for causing most easy growth of weeds, weeds are more not easy to growth.
Initial analysis, why the present embodiment water and soil maintains effect so good, individually with stalk especially size straw Stalk covering furrow is that on the one hand, oblique cloth ridge, especially Z-shaped cloth ridge are also that on the one hand zigzag cloth ridge virtually slow down water Eroding velocity is flowed, and then reduces silt content.
The planting patterns of the present embodiment is still in conceptual phase, and for big farming household, can this planting patterns push away Water and soil conservation rate extensively is depended not only on, cost benefit is additionally depended on.
Although the principle of the present invention is described in detail above in conjunction with the preferred embodiments of the present invention, this area skill Art personnel are it should be understood that above-described embodiment is only the explanation of the exemplary implementation to the present invention, not to present invention bag Restriction containing scope.Details in embodiment is simultaneously not meant to limit the scope of the invention, in the spirit without departing substantially from the present invention and In the case of scope, any equivalent transformation based on technical solution of the present invention, simple replacement etc. are obvious to be changed, and is all fallen within Within the scope of the present invention.
