With the adjustment of the planting structure in China, in recent years, the planting area of ​​strawberries has been expanding year by year. There are not only a few households with a single-family area of ​​more than 3 hectares. With large cultivation area and serious weeds, its effective control is a major production problem. First, the type and damage of strawberry weeds in the open field. The weeds in open field strawberries include broadleaf weeds such as Amaranthus retroflexus, grayish green peony, purslane, cocklebur, and field bindweed, as well as grassy weeds such as crabgrass, barnyardgrass, setaria viridis, and Thousand-gold. Strawberry plants are low in height, high in planting density, and difficult to weed. In addition, the amount of basal fertilizer in Strawberry Farm is large and the amount of irrigation water is large, so weeds thrive. Weed damage can reduce the yield of strawberries by 15-20%, and weed control cannot be ignored. Second, the cost of manual weeding and chemical weeding. After planting, manual weeding requires 270-375 yuan per hectare for weeding, and 150 yuan per hectare for chemical weeding. For large-scale production of strawberries, chemical weeding should be considered after planting to reduce investment, reduce costs, and increase efficiency. 1. Soil treatment before and after transplanting. Can be used 48% trifluralin EC 2200-2500 ml / ha, mixed with water 750 kg directional sprayed soil, spray mixed soil to prevent photolysis; also available 50% Da Huili 1500-3000 ml / ha, before flowering application . Note that these agents cannot be applied before flowering until the fruit is harvested. Stem and leaf treatment agent can effectively control grassy weeds and broad-leaved weeds, the use of time for the emergence of weeds Qi. The available agents are 15% stable and kill 670ml/ha, 10.8% high efficiency gaiseng EC 450ml/ha, and 5% quebracho EC 750ml/ha. When the temperature is low and the soil moisture is poor, the application of the herbicide is effective, and the herbicidal effect is not good. When the temperature is high, soil moisture is good, and the weeds grow vigorously, the herbicide has good weeding effect. To prevent broad-leaved weeds in strawberry, we must be cautious. We must use different herbicides and adjust the amount of herbicides in response to the growth and development of strawberries. Before wintering, strawberries can be sprayed with 24% Ke Qule 300 ml/ha and 450 kg evenly, which can effectively control broad-leaved weeds such as purslane, plate branch, and lime green; strawberry field after harvest Leaf weeds can be sprayed with 24% Ke Qule 375 ml/ha and 450 kg water. When grass weeds and broad-leaved weeds are mixed together, Kekuola and Jingwen must be staggered to prevent the use of the barrels. Otherwise, they will cause phytotoxicity.
