Watermelons grow a lot of pointed melons. What happened?

Cucumber's mouth is actually the place to pinch the top flower. Sharp-billed melon is a normal part of the stalk or upper part of cucumber, and the part near the flower is small, which is called "sharp-billed melon". Just like this, there is a term called "pointed-billed monkey face". . The main reason for the formation of deformed melons is caused by physiological obstacles. For example, during the flower bud differentiation and development period, the temperature is too low, the differentiation is poor, too much fertilization, too much nitrogen fertilizer, too much nutrient accumulation, and the flower bud cell division is very vigorous, leading to physiological proliferation.

The main reason is that the photosynthesis of plant leaves is reduced, and the fruit can not get enough nutrition when it expands, which is easy to produce too many fruits or later stages. If the nutrient supply is insufficient, cucumber can only ensure the growth and expansion of fruits in some places, and it cannot be balanced. Nitrogen fertilizer is an important element to ensure the yield of fruits and vegetables. Too much nitrogen fertilizer will lead to its crazy growth, and too little nitrogen fertilizer will lead to cucumber fruit dysplasia.

The uneven sunshine time of watermelon leads to the inconsistent surface temperature of watermelon, which leads to the watermelon turning white on the ground for a long time and becoming a deformed melon. We can achieve the consistency of temperature by turning the melon and prevent the melon from deformation. Watermelon has strong drought tolerance and is sensitive to excessive air humidity. If the air humidity is too high, it will seriously affect the fruit setting rate, and it is also prone to pests and diseases, especially the continuous rainy weather will make watermelon unable to pollinate and fertilize normally.

During the flowering and fruit-setting period of watermelon, if the temperature in the greenhouse is high and the weather is sunny, outdoor air should be increased to promote air circulation and reduce the humidity in the greenhouse to create the most favorable natural conditions for watermelon pollination. Don't pursue yield unilaterally, leaving a lot of fruits will lead to scattered nutrition, which will make fruit-setting melons lack nutrition and lead to deformed fruits. Early-maturing watermelon seedlings are about 1 month old, and can be planted when 2-3 real leaves grow. Medium-mature watermelon seedlings can be planted in 20-25 days, and late-mature watermelon seedlings can be planted in 7- 10 days. Wide border planting is 2 rows, narrow border planting is 1 row. Watermelon picking should be carried out according to early, middle and late maturity varieties. It takes 25-30 days for early-maturing watermelon varieties, 35-40 days for medium-maturing watermelon varieties and more than 40 days for late-maturing watermelon varieties.
