As the bitter gourd grows in the middle and late stages of growth, it is prone to severance, and the overall benefits will be greatly reduced. In order to ensure that the bitter gourd continues to deflate, the following measures are recommended.

First, we must pay attention to the timely prevention of pests and diseases. The bitter gourd has a reduced ability to resist stress in the middle and later stages, increasing the possibility of infection by pests and diseases, and it requires early prevention. At present, the disease that is harmful to bitter gourd is mainly powdery mildew, which can be sprayed with 12.5% ​​of myclobutanil EC 2000 times or 12.5% ​​Teptopizole WP 1500 times, and 62.25% Siansheng WP 600 times. As the temperature rises, the virus disease will also become a disease that harms the bitter gourd. It is necessary to pay attention to the adjustment of the temperature, and to do a good job of pest control, and use the virus A500 times more than 300 times the amount of ningnanmycin in advance to prevent.

In this particular mention of bitter gourd yellow leaves. Once the yellow leaves have occurred, the bitter gourd has a low ability to sit on melons, the melon strips are small, and the serious ones no longer sit on melons. The loss of the vegetable farmers is serious. This is actually a physiological disease, which is mainly caused by factors such as weight loss, root damage, and species degradation. The solution is to do a good job of prevention: First, before the bitter gourd is planted, it must be sterilized by high-temperature stuffy sheds and deep-turned into the soil. Second, it is recommended that vegetable farmers buy hybrids and not use their own seeds. Because the self-retained varieties have been planted for seven or eight years, their varieties have been degraded and their resistance has been reduced. Third, conditional vegetable farmers can graft bitter gourd, so that the root system is more developed and the incidence of disease is reduced.

Followed by water and fertilizer must keep up. As the temperature rises, the plants grow stronger. This requires that the supply of fertilizer and water must be sufficient, while the bitter gourd is also like the moist environment. Generally, once every 7-10 days, you can pour a little water and apply some high-grade water-soluble fertilizers. Such as music, potassium and more, etc., with 5 to 10 kilograms per acre, the fertilizer can not only provide nutrition for bitter gourd growth, but also conducive to rooting. Afterwards, as the temperature rises again, the amount of evaporation in the shed increases, and the watering time is also appropriately shortened.

If the yellow leaves of the plants are serious, spray 500-800 times aromatic leaf foliar for 7-10 days, combined with 500-times root irrigation, promote root growth, supplement the nutrients needed for bitter gourd growth, and effectively delay the aging of bitter gourd plants. .

Again, take care to remove excess branches. During the middle and late stages of bitter gourd growth, branches and vines are crowded. If not pruned in time, it will not only consume nutrients but also cause field canopy closure. Nutrients cannot be supplied in a concentrated manner, resulting in poor growth of the bitter gourd and reduced resistance to stress.
