A kind of planting method of spring wheat and summer corn twice a year

Abstract

The invention discloses a method for planting spring wheat and summer corn twice a year, comprising the following steps: planting spring wheat from March 1 to March 10 every year in the eastern Hebei region (or a region with a similar ecological climate), and the growth period of spring wheat is between 85 days to 90 days; harvest spring wheat from June 21 to June 30 of the same year; land preparation; sow summer corn before July 10 of the same year, the growth period of summer corn varieties is 100 days to 105 days, The corn is then harvested during harvest time. Among them, "Jinqiang No. 10" is selected as the spring wheat variety, and "Jingyu 16" or "Zhengyuanyu 432" is selected as the summer corn variety. This planting method does not require spring wheat to be covered with film, and is suitable for grain corn. It realizes the planting mode of grain crops spring wheat and summer corn in the eastern Hebei region, which are cropped twice a year and wheat and corn are rotated in one year. It can increase production, reduce costs and improve Benefits, and there is no environmental pollution problem caused by film covering.

Description

technical field [0001] The invention relates to the technical field of agricultural crop planting, in particular to a method for planting spring wheat and summer corn twice a year. Background technique [0002] Eastern Hebei generally refers to the eastern part of Hebei Province and some surrounding counties of Beijing and Tianjin, mainly including Lulong, Qian'an, Funing, Changli, Luanxian, Leting, Linyu, Fengrun, Ninghe, Tongxian , Sanhe, Baodi, Jixian, Xianghe, Changping, Shunyi, Miyun, Huairou, Pinggu, Zunhua, Xinglong, Yutian, etc. This area is geographically close, has common regional climate characteristics, similar agricultural industries, and agricultural production methods There are similarities. Affected by factors such as latitude and climate in this area, the annual frost-free period is about 190 days, and the accumulated temperature above 0°C is about 4200°C. Therefore, there are three main modes of grain planting in the eastern Hebei region. The first type i...

Problems solved by technology

[0007] The purpose of the present invention is to provide a planting method of spring wheat and summer corn twice a year, which can solve the problems that the existing spring wheat multi-cropping summer corn model is not suitable for grain corn and needs to use film to increase the ground temperature, and solves the problems in the eastern Hebei region. The problem of insufficient utilization of light and heat resources has realized the planting mode of grain crops spring wheat and summer corn grown twice a year in the eastern Hebei region and wheat and corn rotation cropping cultivation within a year, which can meet the growth of spring wheat without using film mulching to increase the ground temperature Need to increase food production
