Using manual or various forms of weeding machinery and topsoil operation machinery to cut off grass roots, interfere with and inhibit the growth of weeds, and achieve the purpose of controlling and eliminating weeds. Weeds in crop fields can be prevented and eliminated in time through artificial and mechanical intertillage. Intertillage weeding has strong pertinence, clean and thorough, simple process, which can not only prevent weeds, but also loosen soil and is more conducive to crop growth.

2. Cultivation management and grass control

Through crop rotation, planting green manure and fallow to limit the growth and development of weeds, thus reducing weeds; Organic fertilizer should be fully decomposed before use (some organic fertilizers contain weed seeds); When arranging the crops before and after, we should make use of the inhibitory effect of the previous crops on weeds to create favorable production conditions for the following crops. Edible brewing vinegar with acidity of 4% ~ 10% can also be sprayed, which can not only eliminate weeds, but also disinfect soil.

3. Straw mulching inhibits weeds

Covering with straw or chaff can not only preserve moisture, keep warm, promote roots and fertilize, but also inhibit grass.

4. Cover with plastic film to suppress weeds

Cover with polyethylene film to control weed growth. Covering with black plastic film is the best way to control weeds, but plastic film can't be used to weed (because it contains chemical herbicides).

Extended data:

Artificial intertillage weeding has strong pertinence, which can not only remove weeds between rows, but also remove weeds between plants. Clean and thorough, simple process, not only can prevent weeds, but also provide good growth conditions for vegetable crops.

In the whole process of vegetable crop growth, artificial intertillage weeding can be carried out many times as needed. When weeding, we should seize the favorable opportunity, remove it early, slightly and completely, and do not leave grass to avoid future troubles.
