Problems solved by technology

In recent years, the large outflow of labor forces has changed corn production from the previous "intercropping, mixed and intercropping mode" to net cropping. In order to seek advantages and avoid disadvantages, ordinary people often adopt the "rare row" planting method, with a row spacing of 1 meter to Between 1.2 meters, the density and yield are far below the national average, and the perennial planting habits also limit the high yield of corn

Abstract

The invention discloses a planting method capable of increasing the corn yield. The planting method includes the steps of variety selecting, soil preparing and fertilizing, rational close planting, plant row space determining, sowing, field managing and harvesting after full maturity. Under the same planting density, row space is reduced, plant space is enlarged, the number of planting rows can be increased, land is used in an intensification mode, light leakage loss is reduced, and finally the yield per unit area is increased.

Description

technical field [0001] The invention belongs to the field of crop cultivation and planting, and in particular relates to a planting method for increasing corn yield. Background technique [0002] Corn is an important grain, feed, and economic crop in my country. At present, there is a large gap between my country's average corn yield and the world average. The planting area and per unit yield of corn play an important role in the increase of corn production. However, due to the limited land area in my country, the potential contribution to per unit yield is relatively large. Therefore, focusing on per unit yield is the main way to increase my country's corn production. [0003] The southwest corn ecological region is one of the important ecological regions for corn production in my country. Chongqing, located in the southwest corn ecological region, is affected by low temperature, rain, and little sunshine in the early stage of corn production, and high temperature forced r...
