Herbivores for aquatic vegetable fields

Aquatic vegetables are mainly oysters, oysters, peony root, arrowhead, rhizome, cress and so on. The aquatic vegetable field weeds are different from the weeds in the dryland vegetable fields. Except for the early years of water improvement, some of the wet and weedy weeds such as snaking gizzards, there are mainly valerian, bermudagrass, allosaic sedges, melon fur, and eyes. The aquatic weeds, such as vegetables, sedges, and flat stalks, are very similar to the weeds in rice fields. Aquatic vegetables are more resistant to herbicides. It is safer to use various herbicides to control paddy field weeds. Commonly used herbicides (used before weeds germinate): 1.60% butachlor EC. Apply 75 to 100 ml per 667 square meters (1 mu) and add 30 kg of water spray. 2.12% Echinacea EC. Apply 125 to 150 ml per 667 square meters and spray 30 kg of water. 3.10% agricultural wettable powder. The use of 15-25 grams per 667 square meters, 25 kg of water spray, control of broad-leaved weeds and annual sedge weeds, efficacy is very significant. 4. At the time of farming, we used a mixture of azathioprine and other acaricides (the amount of which was 1/2 to 1/3), so that weeds control almost all weeds in aquatic vegetable fields. Matters needing attention: The entire field requires leveling, herbicide application should be maintained for 2-3 days of shallow water layer.
