Thoroughly remove the bacteria source before the fall of the dendrite in the fall to remove the diseased body and concentrate the removed diseased body; in autumn, the buried soil is sprayed 50 to 100 times the Sooliban or 3 to 5 degrees lime sulfur before and after the spring is unearthed. Plus 300 times the sodium pentachlorophenol to remove bacteria, reduce the incidence; timely removal of diseased leaves in season, disease, disease vines, concentrated deep. Strengthen the management of timely drainage and loose soil after the rain; timely tying up vines, picking up the heart, maintaining the ventilation and light transmission within the rack; increasing potassium, calcium and trace elements, spraying plant growth regulators (such as green wind 95, must receive more, high yield protection And so on), to improve the function of leaves, enhance tree vigor, and improve disease resistance; control production and reasonable burden. In accordance with the growth of plants to determine the yield, the average age of orchards per mu should be controlled at 2500 ~ 3500 kg. Chemicals to control the spread of the ground to eliminate bacteria. For the orchard with severe disease in the previous year, the lime should be limed on the ground before the occurrence of the disease; soil with higher pH value can be used for ground spreading: 1 for Fumei, 1 for sulfur powder, and 2 for lime. The three are evenly spread on the ground. On the one hand, a dose of 1 to 2 kg per mu, or 500 to 600 times liquid sprayed under the sprayer or 500 to 600 times 50% carbendazim, can control the initial infection source from the soil overwintering. Spray protection. During the growing season, spray appropriate concentrations of Bordeaux mixture. Spray once every 10 to 15 days to protect the leaves, branches and ears to reduce the chance of infection. For the disease, the right medicine. In the event of diseases such as white rot and anthrax, it is necessary to apply the drug to the disease. However, care should be taken that the agents are used alternately and do not use a single drug. After the fruit is stained, to prevent pesticides from contaminating the ear, 500 times 9281 or 12% green milk copper 600 to 800 times can be used. We must scientifically and rationally use pesticides, reduce pesticide residues, and master safe drug use technologies.
