Strawberry malformation prevention

The main cause of strawberry malformation is poor pollination and fertilization, but the extent of its occurrence is related to factors such as variety, grade of flowers, insects visiting flowers, temperature and humidity, and spraying of flowers during flowering. Therefore, the following countermeasures should be taken into consideration in the prevention of strawberry malformation in production.
Arrangement of suitable pollination varieties Due to the difference in sex between females and males, strawberries should be selected as pollination varieties and mixed with the main cultivars. Baochao Zaosheng and Chunxiang are rich in pollen. Yantai greenhouse strawberry, the main plant varieties for the early cross-bearing, pollination varieties of Chunxiang, Fengxiang, pollination varieties accounted for 5% to 10%, can effectively reduce the deformity rate.
In the shed, strawberries planted with beehives are cultivated in early flowering periods, and there are few natural flowering insects in the early stage. Therefore, it is better to place beehives in the protected areas. This method has been widely adopted in Japan and works well. The bees usually fly at a distance of 400 meters. The visiting time is from 8 to 9 o'clock in the morning to 3 to 4 o'clock in the afternoon. The activity temperature range is generally 15 to 30 oC. Other visiting flower insects should also be protected and utilized.
Temperature and humidity control during the flowering period should strictly protect the temperature and humidity in the ground. The temperature should be controlled at 20 ~ 28 °C. It is necessary to release air in a timely manner to reduce the temperature and humidity. Using a drop-free film prevents the effect of water droplets. Drip irrigation can effectively reduce the air humidity in the protected area. As long as the surface does not dry during flowering, it generally does not require irrigation.
Sparsely fruiting and fruiting sparse prone to the occurrence of high grade secondary flowers, which can significantly reduce the abnormal fruit rate of strawberry, and it is beneficial to concentrate nutrients and increase fruit weight and fruit quality.
In order to reduce the number of pesticides used for the protection of pests and diseases in protected areas, integrated measures based on agricultural control should be adopted, and as little or no medication as possible should be used. If the pests and diseases are more serious, you should pay attention to medication before or after flowering.
Artificial pollination was performed at 11 to 12 noon during the peak of anther cracking, and manual artificial breeze (using a fan, etc.) was used to artificially assist pollination, which also had good results.
