How to weed organic vegetable field

Mainly refers to artificial cultivating and weeding. Artificial cultivating and weeding are highly targeted, which can not only remove the weeds between the rows, but also remove the weeds between the plants. It is clean and thorough, and the technology is simple. It can prevent weeds and provide good growth conditions for vegetables. In the whole process of vegetable growth, artificial cultivating and weeding can be carried out as many times as needed. When weeding, we must seize the favorable opportunity to remove the early, small and complete, and not leave the grass, so as not to cause trouble.

Second, strengthen cultivation management and control

Control weeds by using cultivation techniques that limit the growth and development of weeds (rotation, green manure, fallow, etc.). Organic fertilizers should be fully cooked, as some organic fertilizers contain weed seeds. The use of the former crops to inhibit weeds creates favorable production conditions for the crops. It can also spray edible brewing vinegar with acidity of 4%~10%, which can eliminate weeds and disinfect the soil. It is better to spray the weeds in young days.

Third, cover the grass

Covering with straw can not only play the role of protecting, heat preservation, root promotion and fertilization, but also has the effect of inhibiting grass. The coverage per acre is about 400 kilograms, whichever is tight. Straw coverage should also have a good coverage period.

In addition, the mulch can also be used to cover the grass. Covering with mulch film, to improve the quality of mulching film, weeds grow less. When covering the mulch film, it should be tightened and flattened to reach the ground. If the quality of the cover film is not good, it is not only easy to ventilate, but also has poor heat preservation, water retention and fertilizer retention effects, and it will promote weed growth. Covering with a black mulch film has the best grass-soil effect, but it is not possible to cover the weeding with a grass film (because it contains a chemical herbicide).
