Description

A kind of cultivation method of drought-resistant maize

Technical field:

The present invention relates to proportion of crop planting technical field, be specifically related to a kind of cultivation method of drought-resistant maize.

Background technology:

Corn (formal name used at school: Zea mays), Chinese first cereal crops, main producing region is positioned at large corn belt, third place in the world---corn belt, Chinese Pine the Liao Dynasty Plain.

Corn have the laudatory title of life prolonging food, contains rich in protein, fat, vitamin, trace element, cellulose and polysaccharide etc., and great potential and the corn with the high nutrition of exploitation, high biological function food have the effects such as fat-reducing longevity.

Corn is a kind of common cereal crops, is mainly produced in the north, has two kinds of yellow maize, white maizes, and wherein yellow maize contains more vitamin A, very useful to people's eyesight.

And the beautiful sowing area in nonirrigated farmland accounts for 2/3 of the total sowing area of China's corn, and because the frost-free season of China various places is different in size, how much uneven rainfall is, the time that damage caused by a drought occurs is different, so just cause many general methods bringing good effect for this class corn on dry land, also can waste a large amount of time and manpower.

Summary of the invention:

Technical problem to be solved by this invention is to overcome existing technological deficiency the cultivation method that a kind of method is reasonable, implement simple, cultivation effect is good a kind of drought-resistant maize is provided.

Technical problem to be solved by this invention adopts following technical scheme to realize:

A cultivation method for drought-resistant maize, is characterized in that: comprises the following steps,

Step 1, the spring of ploughing protect: apply organic manure autumn, plough and rake the soil level in time afterwards, protect and hold the soil moisture after autumn rain.No longer turn over spring, and when starting to thaw, and repeatedly alternate raking the soil level anyhow, destroys capillary, makes soil defincienct in the upper and excessive in the lower;

During sowing, hold power trench digging, the shallow blinding of need to deep ploughing, seed is stepped in program request, and seed and subsoil are combined closely.Suppression of soil, once completes continuously, avoids the evaporation of water in soil.The suppression of sowing limit, limit;

Step 2, kind are selected and are processed: before corn seeding, will carry out seed drought resisting exercise, mainly adopt dry wet cycling method to process seed, method is that seed is soaked to two round the clock in water at 20-25 ℃ of temperature, after pulling out, dries sowing.Also can adopt medicament method for soaking seed, with calcium chloride 1kg, add water 100kg, seed soaking 500kg, can sow after 5-6 hour; With succinic acid solution seed soaking 12-24 hour, dry sowing after making corn suction moisture; Or soak seed with 20-40mg/kg methyl α-naphthyl acetate;

Step 3, begin sowing in good time: corn is arranged in to sowing before rainy season set.During sowing, run into arid, at dry ground layer, surpass 6cm, the good plot of soil moisture, take suppression to put forward moisture in the soil, or borrow moisture in the soil sowing and moisture creating sowing.During maize growth, take to intertill loose table soil, reduce evaporation, to intertill in time after the rain especially;

Step 4, the rational application of fertilizer: applying organic manure, chemical fertilizer, increase stalk and stubble in field amount, in crop rotation, insert mung bean and legume, support field fertilely, with 5000 times of liquid of 0.3% potassium zinc sulfate, spray 2-3 time;

Step 5, fiting chemical reagent:

5.1, drought resistance agent: use drought resistance agent 750g/hm ²to water 150kg, at corn, be evenly sprayed on blade booting stage;

5.2, water-loss reducer: to corn coating or dressing, execute water-loss reducer 7.5kg/hm during corn seeding in cave with the water-loss reducer of concentration 1.0%-1.5% ².

Beneficial effect of the present invention is: said method is very simple, and very clear of method of control, so just be applicable to librarian use specialty or non-professional plantation, and the cost compare of the material of above-mentioned steps is low, the agricultural chemicals using, chemical fertilizer etc. are all extremely easily to obtain, and price is not high.The inventive method rationally, enforcement is simple, cultivation effect is good.

Embodiment:

For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below further set forth the present invention.

A cultivation method for drought-resistant maize, is characterized in that: comprises the following steps,

Step 1, the spring of ploughing protect: apply organic manure autumn, plough and rake the soil level in time afterwards, protect and hold the soil moisture after autumn rain.No longer turn over spring, and when starting to thaw, and repeatedly alternate raking the soil level anyhow, destroys capillary, makes soil defincienct in the upper and excessive in the lower;

During sowing, hold power trench digging, the shallow blinding of need to deep ploughing, seed is stepped in program request, and seed and subsoil are combined closely.Suppression of soil, once completes continuously, avoids the evaporation of water in soil.The suppression of sowing limit, limit;

Step 2, kind are selected and are processed: before corn seeding, will carry out seed drought resisting exercise, mainly adopt dry wet cycling method to process seed, method is that seed is soaked to two round the clock in water at 20-25 ℃ of temperature, after pulling out, dries sowing.Also can adopt medicament method for soaking seed, with calcium chloride 1kg, add water 100kg, seed soaking 500kg, can sow after 5-6 hour; With succinic acid solution seed soaking 12-24 hour, dry sowing after making corn suction moisture; Or soak seed with 20-40mg/kg methyl α-naphthyl acetate;
