[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 irrigatio...

Embodiment 1
[0035] Step 1, select corn seed and soil preparation;
[0036] For the seeds, choose Xianyu 335, a corn hybrid with high yield, high quality, density resistance, lodging resistance, fast dehydration, and strong disease resistance.
[0037] Carry out soil preparation, including pre-winter soil preparation, deep application of base fertilizer and pre-sowing soil preparation;
[0038] Soil preparation before winter: Use a straw baler to bundle and recycle the crop straw on the surface, and then use a heavy-duty disc harrow to crush the remaining crop straw on the surface and mix it evenly with the topsoil; or use a heavy-duty disc harrow to scrape the surface The crop stalks of the previous crops are preliminarily rolled and cut and dried in the sun for about 15 days, and then the crop stalks on the surface are fully rolled and crushed with a heavy-duty disc harrow and mixed with the topsoil evenly;
[0039] Deep application of base fertilizer: every 667m 2 Use a manure spreade...

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...
