In recent years, due to the rapid development of urban population, the area of ​​strawberry cultivation in the suburbs of the city has become larger and larger to meet the growing demand of the market. Although the quality and quantity of high-quality strawberry varieties are gradually updated, the yield and quality are constantly improving, but in the process of strawberry production, the growth and damage of weeds have a certain impact on the yield and quality: First, there are a large variety of weeds. Both leaf weeds and broad-leaved weeds can grow in succession or symbiotically with each other; second, the amount of fertilizer required by strawberries themselves is large, and the amount of fertilization in the field is also large, which can easily lead to the growth of fertilizers and water; and thirdly, weeds multiply quickly and have high density. The symbiotic contradiction between competing with the strawberry, competing for fertilizer, and competing for water is large; the fourth is that the weeds are prone to induce pests and diseases. At present, strawberry seedlings, spurs and related management work have been carried out in various places. Farmers should start from the strawberry nursery and start from the seedling stage to take comprehensive measures to control weeds and provide quality and robust strawberry seedlings in time.
First, use agricultural measures to lay a good foundation for weeding
First, the strawberry nursery base should be replaced every year, which can change the weed structure, control the weedy weeds, and reduce the damage of potential pests and diseases. Second, it is clear-cutting tillage and soil, and some of the weeds will be sun dried; The cultivator loosens the soil and removes weeds at any time, especially the weeds at Tanabe, to purify the surrounding environment.
Second, using chemical means to kill weeds of different ages
One is that soil treatment kills pre-bud weeds. When the strawberry seedlings are transplanted from the nursery of the nursery to the virgin planting field, one can spray 40% trifluralin EC 100-200 ml/mu, and water 100-200 kg wet on the soil surface, and then mix the dental caries with the soil. To prevent photolysis failure. The agent can kill a wide variety of monocotyledonous weeds and some broadleaf weeds. Two can be 50% butachlor EC 100 ~ 125 ml, or 72% Dole EC 100 ~ 120 ml, 100 kg sprayed on the soil surface, can be better to kill the bud before the weeds. Three can be used 50% Daili Li wettable powder 150 ~ 200 g or 25% Emusol EC 110 ~ 170 ml or 24% Goer EC 36 ~ 72 ml, respectively, watered 100 kg sprayed after soil colonization. Four can be used before and after planting with 65% to kill grass sensitive WP 330 ~ 400 grams, watering 100 kg sprayed soil surface.
Second, herbicides are sprayed after the seedlings are transplanted and transplanted. One can use 10.8% efficient Gaixoneng EC to 20 ml, or 15% to kill 70 milliliters of emulsifiable concentrate, and 80 to 100 kg of water for spraying, which can better control 3 to 5 leaf stage grass weeds. Two can be used 84% Xianzhi EC, 100 ml per acre, dilute 100 pounds, annual monocotyledonous weeds and dicotyledon weed control effectiveness in more than 90%. Three can be used 75% sulfotale wettable powder, 50 to 100 grams per acre, dilute to 500 times diluted with liquid in the protective cover spraying between rows. Four can be used 10.8% efficient Gai emergence cream 20 ml, or 15% fine stable to kill EC 70 ml, watering 80 to 100 kg spray, can better control 3 to 5 leaf grass weeds. Two can be used 84% Xianzhi EC, 100 ml per acre, dilute 100 pounds, annual monocotyledonous weeds and dicotyledon weed control effectiveness in more than 90%. Three can be used 75% sulfotale wettable powder, 50 to 100 grams per acre, dilute to 500 times diluted with liquid in the protective cover spraying between rows. Four can be used 10.8% efficient cover grass can add 50% butachlor 60 to 80 ml, dilute 100 to 120 kg, in the seedlings after planting 10 to 15 days, by the field when the high humidity or drizzling spray, can kill A variety of monocotyledonous weeds and broadleaf weeds. Five can be used 20% paraquat concentrating agent 200 times, directed to spray between the rows of strawberries, before spraying on the nozzle to add a protective cover to prevent injury to strawberry seedlings.
