Vegetable field chemical weeding technology

1. Cucumber, pumpkin, melon, watermelon, bitter gourd, gourd and other melon vegetables: Cucumber is sensitive to pesticides. Many herbicides can not be used in cucumber fields. 25% of glufosinate or 48% of dilamine can be used per acre. 200 grams, or 33% of the weeding emulsifiable concentrate per acre, 100-150 grams, sprayed evenly on the soil surface after 150-200 kilograms of water. Other melons are generally applied after transplanting seedlings or after live seeding. Pumpkins and melons should be sprayed to the surface of the ground with a diameter of 6 to 8 leaves and a vine length of about 20 centimeters, using 48% trifluralin 100 grams per acre or 200 grams of water. The soil is 1 to 3 cm deep.
Second, cauliflower, cabbage, Chinese cabbage and other cruciferous vegetable land: can be used in the transplanting of the seedlings after the use of 25% herbicide ether wettable powder 500 ~ 700 grams, 75 ~ 100 kg of water, directed spray on the surface , or with 48% trifluralin 150 to 200 g (50% can also be used prometryn 100 g), 75 to 100 kg of water, directed spray ripper 2 to 3 cm deep to the surface, spraying the soil with the agent Mix well.
Third, beans, lentils, beans, soybeans and other vegetable: before sowing per acre with 48% trifluralin 100 g, 100 kg of water, sprayed on the soil surface, then ripper 1 to 3 cm deep and 3 days after sowing. For example, after applying seedlings after sowing, 50% of the grass can be used for 100% of the grass, and 75-100 kilograms of water can be sprayed on the surface of the soil. After the emergence, chemical weeding is generally not carried out, and it is not necessary to loosen the soil.
