Solanum vegetables: such as tomatoes, eggplants, peppers, etc., optional herbicides are: 72% dole EC 100-150 ml per acre or 48% dimethoamine EC 150-300 ml per acre, respectively, watered 30 kg Covering the film after sowing; 33% weeding through emulsifiable concentrate 150-300ml per mu; or 24% gourd emulsifiable concentrate 50-100ml per mu or 50% saikojin wettable powder 50g per acre, dilute 40-50kg respectively. , Covering the mulching film after spraying after spraying seedlings after sowing. Beans, such as peas, soybeans, cowpea, etc., optional herbicides: 48% trifluralin EC 100-150 ml per mu, watered 40-50 kg; 50% oxaprofen wettable powder effective per mu Ingredients 23-45 grams, watered 40-50 kilograms, before planting mixed soil preparation after soil preparation, and then sowing film; 33% weeding through EC 150-200 ml per acre, 50% acetochlor EC 70 per acre - 150 ml, watered with 40-50 kg, or 50% Simazine WP active ingredient 33-100 grams per acre, watered 40-50 kilograms, apply the film before emergence after sowing. Cruciferous vegetables: such as Chinese cabbage, red cabbage, cabbage, cauliflower, etc., the herbicides that can be used are: 33% weeding through EC 100-150 ml per mu, 48% pull rope EC per mu 150-200 ml, 50 The percentage of 100% to 100 ml of perchloric perchlorate and 50% of Dahuili WP can be 100-200 grams per mu, and the water is weighed in the range of 40-50 kg and sprayed on the surface before coating. In the film application of herbicides should pay attention to several points: First, the amount of water per acre can not be too low, only to ensure that the humidity can enhance herbicide development, penetration ability; Second, spraying can not be repeated spraying, to be in place once, Avoid increasing the concentration to produce phytotoxicity; Third, trifluralin, oxathione has a strong volatility, after the application must be mixed with gingiva and soil, mix deep to 2-3 cm; Fourth, the film must be strict , Neither leakage of drugs, nor cover film, found that ruptured membranes should be promptly filled.

In the lower temperature season, in order to increase the price of vegetables to market in the morning, in recent years, the use of plastic film covering methods to increase temperature and heat preservation has been used to promote early maturation and yield increase of vegetables. At the same time, weeding and weeding have been used to increase productivity. However, many years of experience in the teaching of chemical weeding in the membranes tell us that if the herbicides are not properly selected or used in the wrong manner, weeds will not be eradicated, the vegetables will cause phytotoxicity, and the three will pollute the environment. Reduce the market value of vegetables. In order to give full play to the effects of herbicides, the herbicides that are suitable for use in eggplant, legumes and leafy vegetables are described below:
