Abstract
The invention discloses a corn planting and cultivating method. The corn planting and cultivating method includes the following steps of selecting a corn variety and conducting soil preparation before planting, arranging wide rows and narrow rows at intervals, sowing corn, completing sowing, pipe paving, film paving and soil covering through an air suction type precision seeder, and conducting field management in the seedling stage, the ear stage and the flower stage, wherein the width of each wide row ranges from 85cm to 95cm, the width of each narrow row ranges from 25cm to 35cm, a drip irrigation zone is paved in the middle of each narrow row. According to the corn planting and cultivating method, due to the fact that the method that the wide rows and the narrow rows are arranged at intervals is adopted, the number of drip lines which are used can be lowered. Modifiers are sprayed in the early period of the field management in the seedling stage to control the plant height and the ear position, and the defect that through a conventional planting method, the corn easily falls over due to the fact that the plant height is large and the ear position is high is overcome. Pesticide is sprayed through a self-propelled high-stalk crop boom sprayer in the middle and later period of management to control pests, the influences of natural disasters on corn growth are reduced, and the influences on productivity caused by a large number of European corn borers, cotton bollworms, aphids, leafhoppers and red spiders appearing after corn jointing are eliminated.
Description
Technical field
The present invention relates to proportion of crop planting agricultural method technical field, specifically spring corn drip irrigation wide-and narrow-row cultivation method.
Background technology
Corn is the important cereal crops of China, and what generally adopted in land for growing field crops is to wait line-spacing furrow irrigation planting type, and yield level is at 9000～12000kg/ha; Corn drip irrigation cultivation method had started large scale application in agricultural production in recent years, and the effect of its water saving, volume increase has obtained sufficient checking, and yield level reaches 13500～18000kg/ha; By precision drilling, efficiently solve the final singling problem, by the drip irrigation Fertigation, efficiently solve the corn nutrition supply problem of whole breeding time, but also have the large (667m of drip irrigation pipe consumption
2With 700～1100m), drip irrigation corn plant height, the biased height of fringe easily fall, after the corn jointing corn borer, cotton bollworm, aphid, leafhopper and two spotted spider mite occur heavier larger to yield effect, the problem that insect pest cannot prevent and treat; But although, by at artificial Furadan of corn typhon mouth phase, filling with heart control of maize snout moth's larva, need a large amount of manpowers, cost is higher.These problems have limited the universal and effect of drip irrigation corn technology.
Summary of the invention
The objective of the invention is for the problem that exists in above-mentioned cultivating method of crop and defect, a kind of spring corn wide-and narrow-row entire mechanization cultivation method is provided, adopting wide-and narrow-row to reduce hollow billet consumption, early stage machinery sprays conditioning agent and controls plant height fringe position, middle and later periods with the self-propelled type high-stalk crop spraying boom spraying machine pest control of spraying insecticide, reduce the impact of natural calamity on corn growth, realize entire mechanization, reach the purpose of saving of labor, province's fertilizer, water saving, high yield.
The present invention has specifically adopted following technical scheme:
A kind of corn planting cultivation method comprises the following steps:
Step 1, broadcast front selection corn variety and whole ground;
Step 2, Row spacing of maize adopts wide row and narrow row arranged spaced, and wide line width is 85～95cm, and the narrow row width is 25～35cm; In the middle of narrow row, be used for laying irrigate band.Preferably, wide line width is 90cm, and the narrow row width is 30cm; In the middle of narrow row, be used for laying irrigate band.
Step 3, corn seeding: adopt air-aspiration type precision planter to complete sowing, pipe laying, plastic film mulch and earthing; Preferably, the time of corn seeding is that soil 5cm ground temperature is while reaching 12 ℃; The degree of depth of corn seeding is 4～5cm.
Step 4, carry out field management in seedling stage, the field management of fringe phase and the phase field management of flower grain;
Seedling stage, field management comprised: after planting the field stringing connects hollow billet, oozes Miao Shui, according to the every 667m of soil moisture content
215～25m drips
3With water droplet, execute 50% corn drip irrigation special fertilizer (32-10-8) 2～3kg.
The field management of fringe phase and the phase field management of flower grain comprise: by drip irrigation irrigates the maintenance soil moisture content maximum field capacity 60～80% between; Fertilizer is executed with water droplet in the dripping irrigation process.
Step 5, results
When bract jaundice, seed hardening, when black layer appearred in seed embryo back side base portion, milk-line disappeared, and the seed hardening presents the intrinsic color and luster of kind, namely selects suitable reaping machine to gather in the crops, and realizes harvesting, peeling, threshing, returns crop stocks to the field.
In above-mentioned corn planting cultivation method, step 1, describedly broadcast front selection maize seed and refer to and select high yield, anti-dense planting, the corn hybrid seed that resistant to lodging, dehydration is fast, disease resistance is strong, as Zheng Dan 958, KW3564, first beautiful 335.
Describedly comprise whole ground, deep placement base fertilizer and seedbed preparation before the winter wholely;
Whole ground before winter: use straw baler that earth's surface first crop crops straw bundling is reclaimed, then with heavy-duty disc harrow, earth's surface is remained to the first crop crops straw and roll to cut and pulverize and mix with table soil; Perhaps first with heavy-duty disc harrow, earth's surface first crop crops straw is tentatively rolled and cuts and dryness in the sun, then with heavy-duty disc harrow, the first crop crops straw of dryness in the sun is fully rolled to cut and pulverize and mix with table soil;
Deep placement base fertilizer: every 667m
2Evenly spread fertilizer over the fields the mixed fertilizer of 1000 kilograms of barnyard manure and 10～20 kilograms of diammonium phosphate, then plow and turn over, the degree of depth of plowing is at 25～30cm;
