Fruit and vegetable pests and pesticides reduction control
The technology mainly uses agricultural measures, physical trapping, utilization of natural enemies, biological pesticides and high-efficiency and low-toxic chemical pesticides to effectively control the occurrence of pests and diseases in fruit and vegetable fields. 1. Agricultural measures. 1 Orchard combined with winter pruning, cut off diseased branches, diseased fruit moss, and dried fruit. Thoroughly scrape old skin, skin, and tumors. Remove ground litter, weeds, diseased skin, cover wheat stalks or crop stalks. 2 Reasonable rotation of vegetable fields, remove the residual leaves, pests and weeds of the former crops, and increase the application of organic fertilizer. Cultivate or irrigate. 2. Protected vegetable straw reactor technology. Dig a pool of 600-700 cm long, 110-120 cm wide and 100-120 cm deep in the inner side of the entrance gable of the greenhouse. Leave 50×50×60 cm of gas at 120 cm from the bottom of the pool. Road, the base of the CO2 switch with an inner diameter of 45 cm at the exit of the airway. Place corn stalks on the gas storage tank, then water and sprinkle the bacteria. A total of four floors. The ratio of the strain, straw and water is 1:500-750:750-1500, sealed, and the two ends are inserted into the hollow tube. Each shed (50 m × 8 m) uses 1.5 to 2 tons of straw at a time, and is added once every 60 days, usually 2 times. Replenish water once every 15 days. Install the CO2 switch on the base of the CO2 switch. The boot time depends on the growth period of the crop. The leachate in the gas storage tank can be used for rooting and spraying. Irrigation roots each time 250 ~ 300 ml per plant, generally 2 to 3 times, the filtered leachate can be sprayed, spray once every 15 to 20 days. 3. Physical measures. 1 insecticidal lamp traps adult insects. It mainly kills golden moths, beet armyworms, underground pests and so on. A lamp can control 40 to 60 acres, depending on the height of the crop vegetables, the height is 1.2 to 3 meters. 2 New type of attractant to trap male moths: According to the pest type, different attracting cores are selected. Each attractor controls 3 to 5 mu, and the lure core is changed once every 1-3 months. When the pests occur, the moth peaks are 3 to 5 Take other preventive measures in a timely manner within days. 3 swatches to kill whitefly, mites, spotted fly and so on. According to the tropism of pests, colored hard plates or commercial swatches are hung in the field, 30 to 40 pieces per acre, and oil is repainted 7 to 10 days. There are yellow boards, blue boards, and so on. 4 solar disinfection control protects the soil from pests and diseases. Add lime nitrogen, straw, water and disinfection. 4. Biological control. Recommended agents: 0.5% azadirachtin emulsifiable oil 800 ~ 100 times liquid; Ao green 1 700 ~ 1000 times; 5% pyrethrin emulsifiable oil 1000 ~ 1500 times; 1.8% avermectin EC 3000 ~ 5000 times liquid, Wuyin Conventional sprays such as gram gram gram and gram bacterium. 5. Chemical control. Use high-efficiency and low-toxic chemical pesticides, such as 10% to remove 1500 times of emulsifiable concentrate, 5% cypermethrin 1000 times solution. 6. New spray equipment. Choose new medicines such as guards to avoid running leaks. 7. Suitable for promotion areas. Fruit trees and vegetable growing areas in Shandong Province.
