First, flower bud differentiation or poor pollination results in the inability to produce auxin in the ovary, which in turn causes cucurbits. For this situation, we can use the means to wipe the fruit, supplement the auxin to the fruit, promote the sitting of the melon and prevent the melon from becoming melon.
Second, excessive temperatures lead to melons. When the greenhouse temperature exceeds 35°C during the daytime and it rises above 20°C during the night, it will lead to plant growth, resulting in strong nutrient growth and poor reproductive growth. Therefore, when farmers usually manage, the daylight temperature in the shed should be controlled at 20-23°C, and the temperature should be controlled at 13-15°C at night to prevent the temperature in the shed from being too high.
Third, planting density, plant closure, leading to melon. The planting density is high, and the plants have poor ventilation and light transmission. Especially after pollination of the fruits, if the light is insufficient, the lack of nutrients produced by the leaves will easily lead to the pumpkins. Therefore, when planting farmers, we must pay attention to the density of planting, and timely removal of the old leaves at the bottom of the plant, increase the ventilation of plants to see the luminosity, prevent chew.
