Abstract

The invention provides a method for using cruciferae crops as wheat field green manure and relates to the technical field of crop planting. According to the method, soil fertility can be improved andphysical and chemical characteristics of soil can be improved; in addition, the application amount of inorganic fertilizer can be effectively reduced, soil moisture is increased and drought is alleviated. The method comprises the following steps: S1, carrying out soil preparation; S2, sowing oilseed rape green manure; S3, carrying out field management on the oilseed rape green manure; S4, ploughing and burying the oilseed rape green manure into the soil; S5, sowing afterreap winter wheat. The technical scheme provided by the invention is suitable for the perennial cultivation process of wheat.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for using cruciferous crops as green manure in wheat fields. Background technique [0002] The Loess Plateau is the main production area of ​​dryland wheat in my country. For a long time, drought, little rain and poor soil are the main factors that limit the growth of crops in the Loess Plateau. According to statistics, the average organic matter content of the Weibei dry plateau in the central and southern part of the Loess Plateau is 11.4g / kg, which is the main distribution area of ​​low-fertility soil; at the same time, the precipitation in this area is low (annual rainfall is only 550mm) and the annual rainfall distribution is uneven (July-September rainfall accounts for about 60-70% of the annual rainfall). As the main crop in the Loess Plateau, winter wheat is mainly planted once a year, and summer fallow-winter wheat is the main planting mode in this area. ...
