Prevent more nitrogen and less potassium The demand for nitrogen, phosphorus, and potassium for zucchini is potassium, followed by nitrogen, and phosphorus. The temperature is high in spring, if too much nitrogen fertilizer, it is easy to cause the zucchini to grow excessively. Therefore, the top dressing in spring is mainly high-potassium compound fertilizer. Prevent high temperature and drought Zucchini is not tolerant to high temperature. High temperature and drought will not only reduce yield, but also induce virus diseases. The temperature is relatively high in spring. If ventilation and watering are not timely, it is easy to cause high temperature and drought in the shed, leading to the occurrence of virus diseases. In addition, the temperature in the shed is high, and the zucchini is prone to grow excessively, causing melons to melt. Therefore, it is necessary to strengthen ventilation in spring and water in time to avoid the formation of high temperature and arid environment in the shed. Under normal circumstances, the temperature in the shed should be controlled at 20 to 24 degrees Celsius during the day and 12 to 14 degrees Celsius at night. Water in time when it is dry, and plow to loosen the soil in time after watering. Prevent falling flowers and fruits Artificial pollination is carried out from 6 to 8 o'clock in the morning every day. Pick off the male flowers to expose the stamens and apply a few strokes to the styles of the female flowers. For auxin treatment, 2,4-D solution containing 20-25 mg per liter, or anti-falling element solution containing 30-50 mg per liter can be sprayed or dipped in freshly blooming female flowers to prevent flower and fruit drop and increase fruit setting rate . Prevent too many results It is necessary to prevent too much fruit and falling seedlings during the fruiting period. Generally, 2 leaves and 1 melon are suitable for fruit thinning. In the later stage, old leaves and diseased leaves should be removed in time to promote ventilation and light transmission and increase production.
