At present, the bitter gourd in the greenhouse has entered the middle and late growth stages, and the bitter gourd is prone to breakage, so that the overall benefits will be greatly reduced. In order to ensure that bitter gourd is constantly embarrassing, the following measures are recommended. First of all, we must pay attention to timely control of pests and diseases . In the middle and late stages of bitter gourd, the ability to resist stress is reduced, and the possibility of infection with pests and diseases is increasing. It is necessary to prevent it early. At present, the disease that is harmful to bitter gourd is mainly powdery mildew . It can be sprayed with 12.5% ​​nitrile emulsifiable concentrate 2000 times solution or 12.5% ​​terpazole wettable powder 1500 times solution and 62.25% Xiansheng wettable powder 600 times solution. As the temperature rises, the viral disease will also become a disease that afflicts bitter gourd. It is necessary to pay attention to adjusting the temperature and doing the pest control work, and prevent it with 300 times of the virus A500 times mixed with Ningnanmycin in advance. Here is a special mention of bitter gourd yellow leaves. Once the yellow leaves occur, the bitter gourd has a low ability to sit on the melon, the melons are small, and the serious ones are no longer sitting on the melons. This is actually a physiological disease, mainly caused by factors such as heavy mites, root damage and variety degradation. The solution is to do the early prevention: First, before the bitter gourd planting, it must be sterilized in the high-temperature shack, and the soil should be turned deep. Second, it is recommended that vegetable farmers purchase hybrid varieties, and do not use their own seeds, because the self-retained varieties have been planted in seven or eight years, the varieties have been degraded, and the resistance is reduced. Third, qualified vegetable farmers can graft bitter gourd, so that the root system is more developed and the incidence is lower. Secondly, water and fertilizer must keep up. As the temperature rises, the plant grows stronger, which requires that the supply of fertilizer and water must be sufficient, and bitter gourd prefers a humid environment. Generally, water can be poured every 7-10 days, and some high-grade water-soluble fertilizers are applied with water. Such as Le Bar, Potassium, etc., 5 to 10 kg per acre, the fertilizer can not only supply the nutrients needed for the growth of bitter gourd, but also conducive to rooting and strong. Later, as the temperature rises again, the amount of evaporation in the shed increases, and the watering time is appropriately shortened. If the yellow leaves of the plant are serious, spray 500-800 times of Fang Fen Foliar Fertilizer in 7~10 days, and combine with 500 times of roots to promote root growth, supplement the nutrients needed for bitter gourd growth, and effectively delay the senescence of bitter gourd plants. . Again, pay attention to removing excess branches. In the middle and late growth of bitter gourd, the branches are lumpy. At this time, if the vines are not pruned in time, not only the nutrient is consumed, but also the field is closed, and the nutrients cannot be concentrated, resulting in poor growth of bitter gourd and reduced resistance.
