Spring zucchini has "three fears"

A fear of high temperature drought zucchini is not high temperature, high temperature and drought will not only reduce production, but also induce viral disease. The temperature in spring is relatively high. If the ventilation and watering are not timely, it is easy to cause high temperature and drought in the shed, resulting in virus disease. In addition, the temperature inside the shed is high, and the squash can be prolonged and cause melons. Therefore, we must strengthen ventilation in the spring, timely watering, to avoid the formation of high temperature and drought conditions in the shed. Under normal circumstances, the daytime temperature in the shed should be controlled between 20°C~24°C and at night at 12°C~14°C. Watering in time when drought occurs, and cultivating loose soil after watering.

Second, the fear of more nitrogen and less potassium for summer zucchini on the nitrogen, phosphorus, potassium demand to potassium, nitrogen, phosphorus, at least. In spring, the temperature is high, and the zucchini grows vigorously. If there is too much nitrogen fertilizer, it can easily cause leggy, vegetative and reproductive growth disorders, and cause melons to grow. Therefore, the spring must be paid attention to the application of nitrogen less nitrogen fertilizer, high potassium fertilizer-based.

Third, it is feared that aphids and thrips are very prone to viral diseases in the spring, and aphids, thrips, and whiteflies are the vectors that transmit viral diseases. Therefore, we must do a good job of preventing and controlling these pests during this period. If you can set up insect nets at the vents, prevent pests from infiltrating.
