The sweet and refreshing zucchini is a popular vegetable nowadays, and many farmers have planted it. However, in the process of planting, zucchini is very prone to the phenomenon of long-lasting, and some farmers call this phenomenon "crazy". If no measures are taken, the yield of zucchini will be seriously reduced. First, the symptoms of the Western Gourd 1. The hypocotyls of seedlings are overextended at the seedling stage, forming high-stem seedlings, or the stems of the seedlings are weak, the internodes are elongated, and the leaves are thin and yellow, resulting in poor flower bud differentiation and less melons. 2. In the adult stage, the stems and leaves of the plants grow vigorously, and the leaves are thick, but there are few sitting melons. Second, the reason for the long-term gourd 1. High temperature or humidity If the young children do not reduce the temperature inside the seedbed after the seedlings are unearthed, it is easy to cause high seedlings. Or in the seedling stage, the temperature and humidity in the seedbed are high, or in the high temperature and high humidity season, the seedlings are easy to grow. In the growing season, there is less light in the rainy weather, and the temperature is also high at night, which is prone to length. 2. Nitrogen application and excessive watering Excessive nitrogen fertilizer is added to the base fertilizer, and the amount of water planted after the seedlings are planted is too large. Or in order to pursue early seedlings, the amount of nitrogen fertilizer applied in the early stage is too large, the watering is early and the water volume is large, and the temperature is high (especially the temperature in the middle of the night is high). 3, no melon control If all the melons grown on the plants are harvested, only the female flowers that are just open and not open are left, and the water and fertilizer are too long to grow. Third, the prevention measures of the Western Gourd 1. Cultivate age-appropriate seedlings Seedlings with strong roots are cultivated by using nutrient or earthworms. 2, temperature control water After the seedlings are unearthed, or 15-20 days before the seedlings are planted, or after the seedlings are planted, or before the roots are placed, the temperature and moisture management should be paid attention to avoid high temperature and high humidity. condition. 3, spraying control agent In the hot and rainy season, if the seedlings grow too prosperous after planting, the plant can be sprayed with 15% paclobutrazol WP 1500. Note that when spraying, raise the nozzle to wet the leaves, not just to the growth point. Spraying wine. After the root melon is still sitting, it is still prosperous. The plant is sprayed with 15% paclobutrazol WP 2000 times to control the growth of stems and leaves and promote the fruit. Fourth, the remedy of the Western Gourd 1, temperature control water control nitrogen fertilizer After the emergence of the zucchini plants, the temperature must first be lowered (especially in the latter half of the night), followed by watering and nitrogen application. It is recommended to spray 0.3-0.5% potassium dihydrogen phosphate solution on the foliage. 2. Take measures to increase lighting. 3, adjust the number of melons For the plants with strong growth potential, the melons should be properly reserved. For the plants with strong growth potential but more female flowers, the melons should be picked early, and the plants should be picked up in a few days, and the plants with weak growth should have less melons and early melons. . Five, matters needing attention 1, short vine zucchini inter-section length Normally growing short vine (dwarf) zucchini plants with an average internode length of no more than 3 cm. If the internode is too long, it is caused by too much watering. 2. Early control of long plants When the growers have a long trend in the zucchini plants, they must take timely measures to control the plants to resume normal growth. If you wait until the plant is long, then take measures, it is easy to reduce production. The above is some introductions of the occurrence of zucchini. In the process of planting zucchini, farmers must do the above prevention and remedial measures to ensure the yield and quality of zucchini.
