Effect of high temperature: Continuous exposure to high temperature during breeding affects the pollination of Luffa. Improper water and fertilizer: in order to promote the growth of loofah, a large amount of nitrogen fertilizer was applied, resulting in flourishing vines. Too high scaffolding: when scaffolding loofah, the scaffold is too high and the vines consume a lot of nutrients. Management method: The minimum daily illumination time of the plant is not less than 8 hours.

reasons why loofah vines fail to bear fruit

1. Effect of high temperature

Loofah is a thermophilic and heat-resistant crop, and the suitable temperature for growth and development is 2-3 degrees. If it is continuously exposed to high temperature during the cultivation period, it will affect the pollination of Luffa, thus causing melon melting and making it difficult to bear fruit. Therefore, it is necessary to do a good job of shading and cooling in summer.

2. Improper fertilizer and water

Luffa requires high fertilizer and water during its development period. If a large amount of nitrogen fertilizer is applied in the early stage to promote the growth of Luffa, which will cause the vines to flourish and reduce the fruit setting rate, the vines will not bear fruit, so it is necessary to apply less nitrogen fertilizer and more phosphorus and potassium fertilizer during the fruit-bearing period of Luffa.

3. The scaffold is too high

When the scaffold is a towel gourd, the height of the scaffold is too high, and the vines keep growing upwards, which consumes a lot of nutrients, resulting in insufficient nutrients for fruit development, and the vines will not bear melons. At this time, the height of the scaffold should be reduced immediately, and then the long branches should be cut short.

4. Management methods

During the growth period of Luffa, it is necessary to adjust the light and temperature well. The minimum daily light time of the plant should be no less than 8 hours, and the day temperature should be 2-28℃, and the night temperature should be kept at 12-18℃. In addition, when Luffa suffers from poor pollination, artificial pollination should be carried out in time.
