Prevention and control of rotten fruit in greenhouse

Around the Spring Festival is the time when the greenhouse eggplants are on the market. This time is also the time when the eggplant has the most rotten fruit. It is a pity that a result of not paying attention to his hard work is rotten in the greenhouse. Therefore, farmers must make prevention of eggplant rotten fruit, generally do the following:
First, diligent ventilation. Eggplant rotten fruit is mainly obtained from cotton blight, cotton rot, and sclerotinia. These diseases are caused by excessive temperature and humidity in the greenhouse. Therefore, the humidity in the shed should be reduced as much as possible, and the air outlet should be enlarged at noon on a sunny day to do ventilation work. At the same time, the temperature cannot be higher than 32 °C.
Second, timely removal of rotten fruit and diseased plants. Because the temperature in the greenhouse is high and the humidity is high, the bacteria are easy to spread. Therefore, once the rotten fruit, the diseased plant and the diseased leaf are found to be removed in time, the development of the disease is further aggravated by the spread of the germ.
Third, chemical control. Anti-virus sputum plus ethyl phosphine aluminum or kelu, 600 times Dasheng M-45, Plex 700 times spray, once every 5 days, continuous spraying 2 to 3 times, can prevent the occurrence of cotton blight, cotton rot, sclerotinia Pharmaceutics, sulphate, chlorhexidine, baike, or ingredients containing carbendazim, such as ash, ash, etc., can effectively prevent the occurrence of gray mold; streptomycin, new Phytomycin or a drug containing components such as thiazolidine sprayed on the foliage, or sprayed with a copper preparation such as a spring spray or a killer (one or two pairs of sprayers), or a medicament such as crown bacillus or crown bacterium, and chlorobromo Cyanuric acid can prevent bacterial soft rot; flower rot and cotton blight can be sprayed with foliar, kejia, anke, hexagram, raldomir, enoylmorpholine, etc., or at anthers One of the above-mentioned agents can be added to it.
Fourth, rational watering and fertilization and raising the roots. If the eggplant lacks nutrients such as boron and calcium, it is easy to cause the fruit to rot and deteriorate. Therefore, it is necessary to dip the water to keep the soil moist, avoid excessive drought, and ensure the normal water and nutrient supply of the eggplant. At the same time, it is necessary to apply calcium fertilizer to the soil, such as calcium nitrate and ecological fertilizer.
Fifth, remove the flower pedicle. When the petals are infected with germs, they cause diseases such as fruits, leaves, stems, etc. Therefore, the petals and stigma that are slightly yellowed should be removed about 1-2 weeks after the flowering.
In addition, the removed petals, stigma and rotten fruit should be cleaned up in time, not in the greenhouse, so as to prevent the spread of germs.
