Prevention of dormancy period: As the Chinese Shoutao peach is poor in stress resistance and heavy in diseases and pests, it is particularly important to do a good job of preventing and controlling dormancy. After deciduous leaves, first clear the garden, then deep plough the entire garden, destroy the wintering sites of pests and diseases, and reduce the overwintering base of pests and diseases. When the leaf falls to 70%-80%, spraying 1:1:100 Bordeaux mixture with insecticide can eliminate most of the overwintering pests and diseases, especially for diseases such as leaf thinning disease, gummy disease and leaf roller moth. Before spraying, 5 Baume degrees of lime sulfur + 300 times of sodium pentachlorophenol reduced the base of overwintering fungi, bacteria and spider mites, aphids, and scale insects once again. If you fight these two drugs over and over again, you will win the initiative in pest control throughout the year.
Pest control in the growing season: In the early spring, pests and diseases mainly include peach whitefly, green-letter dragonfly, leaf roller moth and leaf leaf moth. The main diseases are perforation, leaf shingle disease, fluidic gum disease and so on. During this period, it was mainly focused on taking two drugs after flowering, spraying mango-manganese zinc with 600 times the amount of 2000 times of extinction, spraying 5000 times of agricultural streptomycin and 600 times of multi-bacteria after flowering. Ling + 2000 times imidacloprid. In the middle and late stages, it mainly prevents and controls diseases such as leaf leaf moths, borer bugs, scabs, punch holes, and black spot disease. Because of the serious perforation, and the combination of bacterial diseases and fungal diseases, SJC should choose fungicides that have both an effect on the fungus and an effect on the bacteria. The effect of screening methotrexate and green milk copper is better. Insecticides mostly use imidacloprid, abamectin, extermination, diflubenzuron and other biological agents and high efficiency, low toxicity and other agents.
High Resolution Distance Sensor
