Problems solved by technology

[0007] (1) It is difficult for conventional corn varieties to fully mature: the growth period of conventional summer corn varieties for summer sowing is 100-105 days, and the required annual effective accumulated temperature is 2600-2750°C. , the annual effective accumulated temperature is only 4500-5000℃, and it is difficult for conventional summer corn varieties to fully mature in two seasons a year
[0008] (2) The first season of corn is difficult to grow normally: the first season of corn is sown in mid-March. In late spring, it is difficult to meet the ground temperature of 5 cm above 10°C required for corn germination. Under conventional field management conditions, the emergence rate of corn in the first season is low and the growth rate is slow.
[0009] (3) Lack of integrated mechanical equipment for film-covered seeding: in the Huanghuaihai summer corn area, the general corn planting machinery is a row seeder, which is difficult to meet the requirements of film-covered seedlings and natural seedling release, and the degree of mechanization of film-covered sowing is low

Abstract

The invention discloses a mechanical planting method for two-season corn in one year, relates to the technical field of corn planting, and solves the technical problems that common corn planted in two-season in one year is difficult to completely mature, the first-season corn is difficult to normally grow, and film mulching and sowing integrated mechanical equipment is lacked. Selecting a grain-feed dual-purpose corn variety with a short growth period and an early-maturing corn variety suitable for machine harvesting; 2, determining a planting period from corn sowing to harvesting; step 3, determining a whole-course mechanized planting mode of harvesting two seasons of silage corn in one year, harvesting one season of silage corn and one season of ear corn in one year, and harvesting two seasons of ear corn in one year. According to the method, effective illumination resources from March to October are fully utilized, the corn variety with the short growth period is selected, the multiple cropping index of the land is increased, successful planting and harvesting of two-season corn in one year are achieved, and the total yield of commercial grain corn or silage corn is increased; whole-course mechanical planting is adopted, the planting efficiency is improved, and the requirements of time nodes are met.

Description

technical field [0001] The invention relates to the technical field of corn planting, and more particularly to a method for mechanized corn planting for two crops a year. Background technique [0002] Corn is one of the main food crops. With the increasing demand and demand for food in people's lives year by year, the demand for corn has also increased for many years, but the supply of corn has remained stagnant, and the self-sufficiency rate of corn has also continued to decline. At the same time, the development of breeding enterprises Rapidly, the demand for corn as silage is also increasing, but the current annual crop silage corn planting model has low total yield and low benefit, which is difficult to meet the demand for silage and growers' pursuit of benefit. [0003] Planting two crops of corn a year, in response to the winter fallow policy in some regions, improve soil structure, promote the transformation of potential soil nutrients, reduce groundwater consumption,...
