Tillage method for controlling aegilops tauschii as malignant weed in wheat fields

Abstract

The invention provides a tillage method for controlling aegilops tauschii as a malignant weed in wheat fields, which is implemented through the following steps: (1) in the first year before wheat seeds are sowed, deep ploughing is chosen by the tillage method, and the ploughing depth is 30cm; (2) in the second year before wheat seeds are sowed, deep ploughing is chosen by the tillage method, and the ploughing depth is 20cm; (3) in the third year before wheat seeds are sowed, shallow rotary tillage is chosen by the tillage method, and the ploughing depth is 10cm. The measure is adopted for two successive years, the seed bank of aegilops tauschii in soil can run out, and from the third year, the shallow rotary tillage mode which is commonly adopted by peasants at present can be adopted. The two-ploughing-and-one-rotary-tillage tillage method carries out ecological control and elimination, can effectively prevent and control the occurrence and harm of aegilops tauschii as a malignant weed in wheat fields, cannot destroy the environment and ecology, and has remarkable economic and social benefits for ensuring grain safety and food safety.

Description

technical field [0001] The invention relates to a method for preventing and controlling vicious weeds of barley in wheat fields, in particular to an ecological method for preventing and controlling barley in wheat fields by using farming measures. Background technique [0002] Wheat is one of the main grain crops in my country. The planting area accounts for about 22% of the total area of ​​grain crops, and the output accounts for more than 20% of the total grain output. It is the main commodity grain and strategic reserve grain variety in my country. It has an important position, and the development of wheat production is of great significance to the development of our country's national economy and people's lives. Wheat has been cultivated in my country for more than 5,000 years and is currently the third largest food crop after rice and corn. Azalea is a vicious weed in wheat fields, and it is the subject of quarantine in many countries and regions. The genetic backg...
