What if the zucchini in the greenhouse only blossoms but doesn't bear fruit?
This is mainly caused by physiological obstacles: first, the partial application of nitrogen fertilizer in the base fertilizer promotes the excessive growth of zucchini, the increase of leaf area and serious shade. Second, the temperature in the greenhouse is too low or too high. Third, there is insufficient moisture or too much humidity in the greenhouse. Such an environment will greatly inhibit the vitality of pollen and style.

Spring zucchini should be protected from more nitrogen and less potassium.
There is more nitrogen and less potassium. The demand of zucchini for nitrogen, phosphorus and potassium is the most, followed by nitrogen and phosphorus. The temperature is higher in spring, if there is too much nitrogen fertilizer, it is easy to cause zucchini to grow too much. Therefore, topdressing in spring must pay attention to less application of nitrogen fertilizer, mainly high potassium compound fertilizer. Protect against high temperature and drought. Zucchini can not stand high temperature, high temperature.

Grasp the "three tubes" after planting zucchini in spring
The 20-25 days from planting to root melon harvest is the early stage of melon fruiting. The key points of management are heat preservation, water control, mid-tillage, root promotion and seedling protection. After setting the value to 5-7 days before the slow seedling, the herbs should be covered in the morning and evening to keep the greenhouse at 25 ℃ ~ 30 ℃ in the daytime, 15 ℃ ~ 18 ℃ at night, and the ground temperature 20 ℃ ~ 25 ℃. After slowing down the seedlings.

Planting beans should be high yield and heavy weight to prevent borers
The adults lay eggs on the tender leaves of the plants. After 5~7 days, the hatched larvae eat into the pods and feed on beans. It is difficult to kill the larvae above 3 instars by spraying after they drill into the pods. Therefore, the control of this insect should strengthen the management of fertilizer and water, ensure that the growth is neat, the flowering and pod setting period is relatively concentrated, so as to gather at the critical period.
