Planting method for increasing yield of summer maize

Abstract

The invention discloses a planting method for increasing the yield of summer maize. The method mainly comprises the steps of seeding, wherein the seed pit depth is 3-5 centimeters, the spacing between every two adjacent seed pits is 40-80 centimeters, the earthing thicknesses of the seed pits are uniform; fertilization, wherein the spacing between a fertilizer pit and the corresponding seed pit is 5-8 centimeters, and 40-50 kilograms of a base fertilizer, 40-50 kilograms of a slow controlled release fertilizer and 1-1.5 kilograms of a zinc sulfate fertilizer are applied to the field per mu; castration and pollination, wherein interlaced or interplant castration is adopted, and auxiliary pollination is carried out in a full-bloom stage; harvesting, wherein harvesting is carried out after the maize is fully mature, grouting lines disappear completely, and grains are completely hardened. According to the technical scheme, the planting method for increasing the yield of the summer maize has the advantages that yield increasing is performed by changing the seed and fertilizer positions, the interlaced or interplant castration method, the harvesting time and the like, during yield increasing, the planting cost cannot be increased, the fertilization amount cannot be increased, and the low cost and high yield increasing are achieved.

Description

technical field [0001] The invention relates to a corn planting method, in particular to a summer corn production increasing planting method. Background technique [0002] Corn is one of the most widely planted crops in the world's agriculture. As the three major food crops, it is known as the "golden" industry because of its abundant output and high usable value. Our country has a large population and the per capita planting land area is small, which requires an increase in the yield of corn per unit area. The current high-yield cultivation techniques for corn use more fertilization. Studies have shown that blindly increasing fertilization will not achieve the purpose of increasing yield, but will cause yield reduction. At the same time Extensive fertilization is also very serious to environmental damage. It is urgent to study a new method of increasing production to overcome the bottleneck problem of corn production in the prior art. Contents of the invention [0003] T...

Our country has a large population and the per capita planting land area is small, which requires an increase in the yield of corn per unit area. The current high-yield cultivation techniques for corn use more fertilization. Studies have shown that blindly increasing fertilization will not achieve the purpose of increasing yield, but will cause yield reduction. At the same time A large amount of fertilization is also very serious to the environment. It is urgent to study a new method of increasing production to overcome the bottleneck of corn production in the prior art.
