Strawberry nursery should not be taken lightly to control weeds
Strawberry production, whether it is in the breeding nursery, or transplanting to the field, the weeds have been accompanied by growth, the harm is serious, one is the variety of weeds, monocotyledonous weeds, broadleaf weeds can breed; Strawberry fertilization is large, easy to fertilize water and long fierce grass; third, weeds multiply fast, high density, with the strawberry contend for the light, struggle for fat, contend for the symbiotic contradiction of the big; fourth is the proliferation of weeds to induce pests. At present, the work of strawberry seedlings has been carried out one after another. Therefore, we should start from the nursery and start from the seedling stage to take comprehensive measures to prevent weeds and provide timely and quality strawberry seedlings. First, use agricultural measures to lay the foundation for weeding. First, the strawberry nursery base should be replaced one place each year. It can not only change the weed structure and control the weeds, but also reduce the pests and diseases. The second is to pick up the ploughing soil and kill some of the weeds. The cultivator loosens soil and removes weeds at any time, especially at the edge of the fields. Second, use chemical methods to kill weeds of different ages. One is that soil treatment kills pre-bud weeds. When the strawberry seedlings are transplanted from the nursery nursery to the virgin planting field, one can spray 40% trifluralin EC 100-200 ml/mu and water 50- 100 kg wet on the soil surface, and then mix the dental caries with the soil. In order to prevent photolysis failure, it can kill a wide variety of monocotyledons and some broad-leaved weeds. Two can be 50% butachlor 100-125 ml, or 72% Dole EC 100-120 ml, watered 50 kg sprayed on the soil surface, can better kill the bud before the weeds. The second is the spraying of herbicides after transplanting seedlings. One can use 10.8% efficient Gaizhi to 20 ml, or 15% fine stable to kill 70 ml, watering 40-50 kg spray, can better kill 3-5 leaf grass weeds. Two can be used 84% Xianzhi EC 100 ml per acre, watered 50 kg, the annual monocotyledonous weeds and dicotyledon weed control effect in more than 90%. Three can use 80% turfgrass WP, 200-300 grams per acre, dilute to 500 times diluted with liquid spraying between the rows. Four can be used 10.8% efficient cover grass can add 50% butachlor 60-80 milliliters, watered 50-60 kilograms, after 10-15 days of seedling leave planting, spray by field high humidity or drizzling, can kill a variety of Monocotyledonous weeds and a variety of broadleaf weeds. Five can be used 20% paraquat concentrate 200 times, directed at the spraying between the strawberry, spray before the nozzle to add a protective cover to prevent injury to strawberry seedlings.
