High-yield corn planting method for family farm in black soil area in northeast China

Abstract

The invention discloses a high-yield corn planting method for a family farm in a black soil area in northeast China. The method comprises five steps of seed selection and scientific sowing, correct use of chemical fertilizers, seedling management and summer deep scarification, pest control and straw returning. The method has the advantages that through a comprehensive corn planting method, the problems that cultivated varieties are many, disordered and poor in resistance, the planting density is low, the population structure is unreasonable, the yield increasing potential is limited, fertilization is unscientific, the fertilizer utilization rate is low, seedling stage management and improper deep scarification in summer affect later corn yield formation and harvesting, disease and insect pests are aggravated due to untimely disease and insect pest control, the corn yield is reduced, improper straw returning causes reduction of soil organic matter content and fertility, and a yield potential is difficult to play are solved.

Description

technical field [0001] The invention relates to the technical field of corn planting, in particular to a method for high-yield planting of corn in family farms in the black soil region of Northeast China. Background technique [0002] As the main component of the new agricultural management system, family farms play an important role in the agricultural field, and are increasingly becoming the organizational carrier for promoting large-scale operations in the main grain-producing areas of Northeast China. However, in the process of creating high-yield maize in family farms in the black soil area of ​​Northeast China, there are: many cultivars, poor resistance; low planting density, unreasonable population structure, and limited potential for increasing yield; Improper early-term management and subsoiling in summer affect the formation and harvest of corn yield in the later period; untimely control of diseases and insect pests leads to aggravation of diseases and insect pests...

Problems solved by technology

However, in the process of creating high-yield maize in family farms in the black soil area of ​​Northeast China, there are: many cultivars, poor resistance; low planting density, unreasonable population structure, and limited potential for increasing yield; Improper early-term management and subsoiling in summer affect the formation and harvest of corn yield in the later period; untimely control of diseases and insect pests leads to aggravation of diseases and insect pests, resulting in a decrease in corn yield; improper straw returning to the field leads to a decrease in soil organic matter content and fertility, making it difficult to realize the yield potential, etc.
