Reasons for planting abnormal fruits of strawberries

Strawberry is a kind of perennial herbaceous fruit tree with high nutritional and economic value, which has a wide range of distribution. its fruit is colorful, soft and juicy, moderate sweet and sour, and rich in nutrition, so it has the reputation of "fruit queen". At the same time, it is suitable for protected cultivation. New Year's Day was listed before, and the economic benefit is high. Strawberries are delicious, but people who have grown strawberries have encountered fruit deformities. What is the reason?

First, the temperature is unreasonable. The most suitable temperature for the growth and development of strawberry is 20-25 degrees, and the lowest temperature during flowering and fruiting period is not less than 5 degrees. Lowering the temperature will affect the growth and pollination of strawberries and are prone to deformed fruits. So be sure to control the temperature of the greenhouse. The temperature of the shed is controlled at 20-25 degrees during the day, 8-10 degrees at night, and the humidity is controlled at 50% 60%.

Second, if there is not enough light during flowering, overcast and rainy weather will inhibit the accumulation of starch needed for pollen germination, thus reducing the pollen germination rate and disadvantageous to fertilization.

Third, too much or insufficient fertilizer will affect the quality of flower bud differentiation, which is not conducive to normal pollination. It is easy to form deformed fruit. The management of water and fertilizer must be strengthened.
