Method for planting summer corn to improve yield

Abstract

The invention discloses a method for planting the summer corn to improve the yield, comprising the following steps: selecting density-resisting compact or semi-compact high-quality summer corn to hybridize; sowing the summer corn in the line-indenting broadband densifying form; managing the corn field; and harvesting the corn in good time. Because the line-indenting broadband densifying corn sowing form replaces the traditional equal line-spacing corn sowing form, and the edge line advantage is created manually, the high-density planted corn group structure and the corn group canopy environment are improved, the light source is fully utilized, the stems of the corn are stout, the corncobs are lower, and the lodging of the plants is prevented effectively. Due to the adoption of the line-indenting broadband densifying corn sowing form, the compact summer corn planting density can be increased from about 4500 per mu of the traditional equal line-spacing corn sowing form to 5500 per mu, the semi-compact summer corn planting density can be increased from about 3500 per mu to 4500 per mu, high yield increasing potential can be achieve, the yield can be increased by about 20%, and the light energy utilization efficiency can be increased by more than 18%. The method has good popularization and application value.

Description

technical field [0001] The invention belongs to the field of corn planting, in particular to a planting method for increasing the yield of summer corn. Background technique [0002] Corn is the second largest grain crop in our country and the main force of increasing grain production in our country. The problem of increasing corn production has become the key to solving our country's food problem. The light and heat resources in the summer corn season are relatively sufficient, and the potential for increasing corn yields is still great. At present, increasing the planting density is one of the important ways to increase the yield of summer maize. However, under the traditional equidistant planting method, high-density planting often leads to deterioration of light conditions within the group, insufficient light and heat in the group, and serious lodging, which limits the yield of summer maize. potential.
