To prevent the deformed fruit of strawberry in the greenhouse, the following points should be noted when planting: 1. Choose varieties with high fertility. 2. Mixed planting. When cultivating varieties with low pollen quantity and low fertility, it is possible to mix varieties with high pollen quantity, high fertility and the same flowering period. According to research, planting red-faced strawberry fields by mixing 10% -20% of other varieties can greatly reduce deformed fruit. Mixed planting can be used for interlace planting or planting around, the effect is very good. 3. Stocking bees. During the flowering period of strawberries, the temperature is low, there are few insects, and the humidity is high, which prevents pollen from flying away, pollination is poor, and various deformed fruits are prone to occur. Stocking bees is the second effective measure to prevent deformed fruit. The time for bees to collect honey and pollination generally starts from 9 to 10 o'clock and ends at 2 to 3 o'clock in the afternoon. The activity of bees is also affected by the temperature, and no activity below 13 ℃ or above 32 ℃. To grow strawberries in greenhouses and greenhouses, bee nest boxes can be placed directly in the greenhouses and greenhouses at about one-third of the north end. The following problems should be solved when keeping bees in the rooms and sheds: First, the nutritional problems of bees. After the first batch of strawberries blooms, the number of flowers gradually decreases, and the nutrition of bees is insufficient. , The nest box should be removed on the day of spraying the insecticide, and then moved into the bee release after the second day. It is best not to spray the insecticide during the beekeeping process; the third is the problem of ventilation, the weather is hot at noon and the temperature is high, Proper ventilation is required, but if the management is not good, the bees will escape; Fourth, the bees should be ventilated and dehumidified before the activities of the bees, to eliminate the water vapor on the shed film, to prevent the bees from getting on the shed film, resulting in the flight death. 4. Strictly limit the spraying of pesticides. Strawberry has a long flowering period and sometimes needs to be controlled by diseases and insect pests. Pesticides, while killing pests and germs, also inhibit the germination of pollen, resulting in malformed fruits due to poor fertilization. The flowers that bloom on the day of spraying are generally not hypertrophic. Therefore, during flowering, spray as little as possible or not. When you have to spray it, you can choose the climate that is not favorable for pollination of strawberries, or when the fruit has been set but the flowers have not yet been opened in large quantities, which can reduce losses.

In terms of physiological functions, vitamins are neither a raw material for tissues nor a substance for supplying energy, but they are an indispensable substance for the body. It has many types and different chemical structures. Most of them are the components of the coenzyme (or prosthetic group) of certain enzymes. They are the indispensable compounds for maintaining the normal growth (growth, health, reproduction and production function) of the body. It plays a catalytic role in the body to promote the synthesis and degradation of major nutrients (proteins, fats, carbohydrates, etc.), thereby controlling metabolism. Vitamins are essentially low-molecular organic compounds. They cannot be synthesized in the body, or the amount synthesized is difficult to meet the needs of the body, so they must be supplied from the outside. The daily requirement of vitamins is very small (usually measured in milligrams or micrograms). They are neither a raw material for body tissues nor a substance for energy supply in the body. However, they do not regulate material metabolism, promote growth and development, and maintain physiological functions.

5. Temperature and humidity management. Greenhouse cultivation, in case of frost or cold damage during flowering period (discoloration of flower heart or blackening of fruit), the inner layer of film can be covered to prevent freezing damage and reduce deformed fruit.
