First, the main cause of strawberry fruit malformation
First, the staged ecological environment is incompatible with the growth and development of some strawberries. Second, the cultivation and management techniques are not in place. Affected factors include temperature, light, moisture, fertilizer, pollination, etc., resulting in poor plant growth in some strawberries. Excessive application of nitrogen fertilizer, boron fertilizer is insufficient, high temperature and drought. For example, when there are too many nitrogen fertilizers, for example, there are too many nitrogenous fertilizers in the flowering stage and there is a lack of boron, and the auxin content in the growing point is increased, so that the flower buds will expand in bands immediately before differentiation, and two or more flowers will differentiate at the same time, resulting in 2- Three peduncles flower at the same time to form chicken crown, double-headed or multi-fruit. Another example is that when boron is insufficient, the flowers are small, pollination is poor, and the fruit shrinks on one side and becomes deformed. When the temperature is high and dry, the watering is excessive, the fruit is easily cracked and the flesh is exposed. Insect pollination is inhibited, fertilization is poor, easy to form flattened fruit.

Second, strawberry misshapen fruit control method
First of all, choose the species with high yield rate. Second, scientific formula fertilization. To achieve a combination of organic fertilizer and inorganic fertilizer, in particular, appropriate proportion of phosphorus and potassium fertilizer should be applied. Each acre base fertilizer should be applied to the farmyard fertilizer 4000 ~ 5000 kg, 40 ~ 50 kg of superphosphate, potassium sulfate 15 kg, holding the boron of 0.2 kg, nitrogen, phosphorus, potassium compound fertilizer 30 kg. Every 20 days after planting, the compound fertilizer was chased once every 20 days, 10 kg per mu, and applied once a month at a later time.
Finally, do a good job of supporting measures. High-efficiency and low-toxicity pesticides are used. Strawberry is pollinated by insects. Sometimes, even in a temperature range suitable for pollination and fertilization, insect pollinators kill insect pollinators improperly, or flowers with low nectar and sugar content cannot attract insects, which will affect pollination. Fertilization produces teratogenic fruit. Avoid pests during the flowering period, remove abnormally shaped young fruits, and often eliminate old leaves and invalid axillary buds.
