Strawberry garden weeds should be controlled frequently

Strawberry plants are low, planting density is high, weeding is difficult. Because strawberry orchard base fertilizer application quantity is big, irrigation quantity is big, weed occurrence quantity is big. Weed damage can cause strawberry yield loss of about 15%-20%. Therefore, attention should be paid to weed control and comprehensive control measures should be taken.

1. Artificial weeding is essential in strawberry production, which is mostly carried out at the same time as intertillage and soil protection. Strawberry annual growth cycle, there are three periods should be intertilled weeding. One is after planting to before winter. Second, in the spring of the next year, after strawberry germination to flowering, in order to preserve moisture and improve soil temperature for the purpose of tillage or fertilizer irrigation after shallow tillage hoe. Third, after strawberry fruit picking, the temperature is getting higher and higher, the rain increases, strawberries and weeds enter the vigorous growth period, which is the key period for weed control.

2, plastic film covering will be made into a turtle-like ridge surface, ridge height 10-15 cm, ridge width 50-60 cm, covered with black plastic film, with good grass control effect. Covering strawberry with transparent film also had certain effect of restraining weeds, but transparent film easily led to premature senescence of strawberry plants.

3, herbicide chemical removal 48% Trifluralin EC used to control many 1-year grass and broad-leaved weeds are germinating seed effect is very good, such as purslane, Salsola, Chenopodium, Polygonum plants and so on. The application method is that after strawberry transplanting, 48% trifluralin 150ml is sprayed on each mu, 50L of water is applied, and soil is covered immediately after application to prevent photolysis. 24% DAKE can kill common broadleaf grasses in strawberry orchard such as purslane, nightshade, sunflower, gray vegetable and cocklebur. 12.50% cyhalothrin emulsifiable concentrate or 35% flumethoprim can be used to control grass weeds. The frequency of spraying should be determined according to the occurrence of weeds, generally 1-2 times.
