In spring and summer, the temperature is high, and the zucchini grows vigorously. If there is too much nitrogen fertilizer, it can easily cause legumes to grow and cause melons to grow. Therefore, in the spring and summer, zucchini top dressing must pay attention to less nitrogen fertilizer, mainly high potassium compound fertilizer.
Zucchini is not heat-tolerant, and high-temperature drought not only reduces the yield but also induces viral disease. The temperature is high. If the ventilation and watering are not timely, it will easily lead to high temperature and drought, resulting in the occurrence of virus disease. Therefore, in the spring and summer, when the drought in the field should be watered in time, after the watering, timely cultivation of loose soil.
Zucchini should pay attention at any time during the cultivation process to remove lateral buds and lateral branches, in the period of fruiting melons to prevent too much results and falling pods, generally 2 leaves and 1 melon as an appropriate amount of fruits to carry out fruit thinning. In the later period of the squash, old leaves and diseased leaves should be promptly blown to promote ventilation.
