In the countryside, I believe that many people have fungi, which is crispy and refreshing like a fungus. It is suitable for planting in the north and south. Today, Xiaobian mainly introduces the three major diseases commonly associated with fungus. Control technology. First, the three major diseases and prevention methods of fungus 1. Brown spot disease, also known as purple spot disease, fish eye disease, and red spot disease, is a bacterial disease. It can occur from seedlings to the end of harvest, mainly affecting leaves. Control method: (1) The cultivated fungus should be rotated with non-Lico and non-falling sunflower crops. This can effectively prevent the occurrence of brown spot disease. (2) For areas where brown spot disease is more serious, the seeds are treated with formalin 100 times solution for 0.5 to 1 hour before sowing to remove bacteria from the seeds. (3) Strengthen field management, properly close planting, rational watering, avoid partial application of nitrogen fertilizer, and timely harvest. At the same time, high temperature and high humidity conditions are given to avoid low temperature dry environment, and to a certain extent, it can also prevent brown spot disease. (4) In the early stage of the disease, spray with 600% of sensible zinc wettable powder 600 times solution or 50% of dexamethasone wettable powder 800 times, once every 7 to 10 days, even spray 2 to 4 times, can control the disease. 2. Gray mold disease generally begins to develop in the middle stage of growth, mainly affecting leaves and petiole, and can cause leaf rot in severe cases. Control method: 50% benomyl WP 1500 times solution or 50% carbendazim WP 1000 times solution can be used at the beginning of the disease, spray once every 10 days, even spray 2-3 times. 3. Earthworms are underground pests that mainly harm seedlings. Control method: It can be used to reduce the overwintering insect source in the early winter. In addition, it can be sprayed on 25 kg of fine soil with 50% phoxim 200 g and 2000 ml per 667 square meters at the time of sowing, and then the poisonous soil is sprinkled in it. Second, the cultivation method of fungus 1. Live cultivation. Pots of 20 cm in diameter, three to four seeds per pot to ensure the emergence rate. In order to facilitate emergence, it can be immersed for 1 to 2 days before seed sowing, and germinated at a temperature of about 30 °C. When the seedlings have three or four true leaves, they can choose to thin the seedlings, and one seedling per pot can be used. Seedlings can be harvested 10 to 15 cm high. 2. Seedling transplanting. Seeds are dried and seeded at a suitable temperature of 28 ° C for 3 to 5 days. If the ground temperature is low, the seeds should be germinated. If it is not a live broadcast, but choose a seedling, 4 to 5 pieces of true leaves can be transplanted and planted.
