Agricultural ecological control 1. Variety selection: Use precocious, high-quality, high-yield and disease-resistant strawberry varieties such as Hongbu, Zhangji, Ningyu, Sweet Charlie and so on. 2. Balanced fertilization: Apply organic manure such as decomposed chicken manure 1500-2000 kg/mu, add 200 kg/mu of cooked cake fertilizer, or 200-300 kg/mu of bio-organic fertilizer as base fertilizer; meanwhile, increase nitrogen, phosphorus and potassium ternary compound Fertilizer 30-40 kg, superphosphate 70-100 kg and so on. 3, plant management: During the growth of greenhouse strawberry, should remove the aging bottom leaves, weak leaves and diseased fruit, cut (pull) in addition to diseased stalks and diseased plants, and remove the Tanabe rot branches, together with the shed Burned outside. 4, control of humidity and disease prevention: winter ridge covers black or silver black mulch, shed in the horticultural garden cloth or disease-free straw, drip irrigation replenishment fertilizer, open ditch around the shed, the use of non-drip agricultural film, Keep the booth clean and airy; timely drainage, ventilation after rain, reduce the humidity in the greenhouse. 5. To remove weed pests: Remove weeds from the garden and destroy them centrally, combine with weeding or cultivating loose soil to kill underground pests. Physical control 1. Solar high-temperature disinfection: The greenhouse is covered with strict membranes, surrounded with compaction of soil, to prevent air from entering, so that the soil temperature reaches 50°C to 60°C, and the soil is subjected to high temperature sterilization to kill the pathogens of the continuous cropping field. After 25 to 30 days of continuous high-temperature treatment, the surface covered film should be removed as soon as possible, and the soil should be allowed to thaw after the rain. 2. Control of temperature and humidity control disease: The flowering result period is the period of diseases such as gray mold, the humidity in the greenhouse is reduced to 50% or less, the temperature is increased to 35°C, the ditch is shed for 2 hours, and then the air is released to cool, which can effectively control the gray mold Diseases and other diseases occur. 3, trapping and killing pests: 1 swatch trapping. Purchase special yellow and blue boards, apply Vaseline + engine oil, then insert yellow and blue boards into the field, or hung between the rows of strawberries. The yellow board is mainly used to kill locusts, and the blue board is mainly used for killing hummer, yellow and blue. The size of the board is 3020 centimeters, 30 to 40 pieces per acre, 30 to 50 centimeters higher than a strawberry plant, and the use of tectonic stickiness to kill aphids and thrips. 2 sweet and sour vinegar trap. Using the adult's tropism, the overwintering adult was seduce with sweet and sour liquor. In the adult period, add 1:2:3:4 ratio of wine, water, sugar and vinegar to the appropriate amount of dichlorvos in the pot, and fill in the half amount of attractant every 5 days, and change the whole amount in 10 days to trap the insects such as the moth and the ground tiger. 1, the release of natural enemies: in the flowering to fruit growth period release predator, according to the ratio of 1:10 to 1:30 ratio of predation to release predators, control of red spider and other pests. 2. Bio-pharmaceuticals control: The bio-pharmaceuticals can be used to control the growth of greenhouses in greenhouses. The use of low-toxic microbial and botanical pesticides, such as fusarium wilt, verticillium wilt, and root rot, can be used. Spore/Bacillus subtilis WP 500 to 1000 times, 10 billion live spores/Bacillus polymyxa wettable powder 500 times; anthrax, gray mold, powdery mildew and other diseases, choose 100 billion live spores/ Bacillus subtilis wettable powder 500 to 1000 times, 300 million live spores/Kharz, WP wettable powder 600 times, etc. Disclaimer: Some articles in this website have been transferred from the Internet.
