Corn planting and cultivating method

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 [0001] The invention relates to the technical field of crop planting agronomic methods, in particular to a spring corn cultivation method with drip irrigation in wide and narrow rows. Background technique [0002] Corn is an important food crop in my country. The equal-spaced furrow irrigation cultivation method is generally adopted in the field, and the yield level is 9000-12000kg / ha. In recent years, the corn drip irrigation cultivation method has begun to be widely used in agricultural production. The effect of increasing yield has been fully verified, and the yield level has reached 13,500-18,000kg / ha; the problem of fixed seedlings has been effectively solved through precision sowing, and the problem of nutrient supply for the entire growth period of corn has been effectively solved through drip irrigation and fertilization, but there are still drip irrigation capillaries. Large amount (667m 2 Use 700-1100m), drip irrigation corn plant height, ear positio...

[0002] Corn is an important food crop in my country. The equal-spaced furrow irrigation cultivation method is generally adopted in the field, and the yield level is 9000-12000kg / ha. In recent years, the corn drip irrigation cultivation method has begun to be widely used in agricultural production. The effect of increasing yield has been fully verified, and the yield level has reached 13,500-18,000kg / ha; the problem of fixed seedlings has been effectively solved through precision sowing, and the problem of nutrient supply for the entire growth period of corn has been effectively solved through drip irrigation and fertilization, but there are still drip irrigation capillaries. Large amount (667m 2 Use 700-1100m), drip irrigation corn plant height, ear position is high and easy to fall, corn borer, cotton bollworm, aphids, leafhoppers and spider mites occur heavily after corn jointing, which has a great impact on yield, and pests cannot be controlled ; Although the corn borer can be prevented and controlled by artificial carbofuran irrigation in the corn big horn stage, it requires a lot of manpower and the cost is higher

These problems limit the popularization and application effect of drip irrigation corn technology
