Three reasons leading to Cucurbita moschata

First, flower bud differentiation or poor pollination, resulting in the ovary can not produce plant auxin, resulting in watermelon. In view of this situation, we can use the means of wiping melon to supplement auxin for the fruit, promote melon sitting and prevent melon from melting.

Second, too high temperature leads to melons. When the temperature in the greenhouse is more than 35 ℃ during the day and 20 ℃ at night, the plant will grow excessively, resulting in exuberant vegetative growth and poor reproductive growth. Therefore, when vegetable farmers manage in peacetime, the temperature in the greenhouse should be controlled at 20-23 ℃ during the day and 13-15 ℃ at night, in case the temperature in the greenhouse is too high and the plants grow and turn melons.

Third, the planting density is high and the plants are closed, which leads to melons. The planting density of the plant is high, and the ventilation and light transmittance of the plant is poor, especially after fruit pollination, if there is not enough light, the lack of nutrients produced by leaves will easily lead to watermelon. Therefore, when planting, vegetable farmers must pay attention to the planting density, and timely remove the old leaves at the bottom of the plant, increase the ventilation and visibility of the plant, and prevent melons.
