Problems solved by technology

[0004] But nowadays, there is no uniform and standardized operation in the process of planting sweet corn from soil selection, environment selection, fertilization, and pest control. More fertilizers are chemical fertilizers that can promote its rapid growth but are more harmful to the human body. The process of pest control In China, chemical control is often used to prevent insect pests from eroding corn by spraying pesticides. Continuous cropping for several years will cause serious soil compaction and flooding of diseases and insect pests

Abstract

The invention discloses a method for planting sweet corn with three harvests a year. The method is to plant sweet corn for three seasons in a year and rotate green manure once a year. 50 days and 65 days after corn transplanting, plant protection drones were used to spray sugar-increasing fertilizers to increase the sugar content of corn. The method of the invention not only rationally utilizes the land, improves the output rate of the land, but also improves the soil through crop rotation, alleviates the continuous cropping obstacle of the soil, and realizes the farming mode combining land use and land cultivation.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a three-harvest sweet corn planting method a year.
