Wheat field mulch weeding method

Abstract

The invention discloses a wheat paddock covering weeding method. Dried rape pods or dried rape straw or a mixture of the dried rape pods and the dried rape straw is adopted, soil surface covering is conducted after wheat is sowed, and then damage of weeds in a wheat field is effectively controlled. The method comprises the following steps that 1, rape straw and rape pods are dried in the sun, the dried rape straw is cut into stem segments being 0.01-20 cm, the dried rape straw and the dried rape pods are obtained separately, and the dried rape pods or the dried rape straw or the mixture of the dried rape pods and the dried rape straw serves as coverings; 2, after the wheat is sowed, the coverings are uniformly broadcast on the basis of 300-1,100 g / m<2>.

Description

Technical field

[0001] The invention relates to a wheat field mulching and weeding method, belonging to the field of agriculture. Background technique

[0002] Wheat is one of the main food crops in my country, with a planting area of ​​more than 30 million hectares, accounting for 20% to 27% of the country's sown area of ​​food crops. Wheat field weeds directly or indirectly affect the yield and quality of wheat by competing with wheat for water, nutrients, occupying ecological space, and spreading diseases and insect pests, which can reduce wheat yield by about 15%. There are about 100 species of weeds in wheat fields in my country, mainly annual and over-year-old weeds. The common gramineous weeds include Triticum aestivum, brome, wild oats, Mai Niang, Japanese Mai Niang, Setaria, Crabgrass , Bluegrass, potweed, etc.; broad-leaved weeds include pig stalk, shepherd's purse, artemisia sowing, Maijiagong, cow chickweed, chickweed, large vetch, mother-in-law and so on.

Embodiment 1

[0040] The dried rape stalks are cut into 2~5cm stems. On the 1st to 12th day after the spring wheat is sowed, 500-700g / m will be sprayed evenly at one time 2 Of dried rape pods, dried rape straw or a mixture of both. When spreading, use a small amount of gradual spreading method. It is not advisable to spread too much cover in a concentrated manner. The purpose is to ensure that the cover can basically fall on the surface of the wheat field, so as to avoid overwhelming the wheat seedlings, that is, so as not to affect the germination and growth of the wheat seedlings; after spraying Normal management.

Embodiment 2

[0041] Example 2. The dried rape stalks were cut into 2 to 5 cm long stems. On the 1-12 days after winter wheat sowing, evenly spread 500-700g / m at a time 2 Of dried rape pods, dried rape straw or a mixture of both. When spreading, use a small amount of gradual spreading method. It is not advisable to spread too much cover in a concentrated manner. The purpose is to ensure that the cover can basically fall on the surface of the wheat field, so as to avoid overwhelming the wheat seedlings, that is, so as not to affect the germination and growth of the wheat seedlings; after spraying Normal management.
