Strawberry Shed Shaped Fruit Prevention
Under the condition of normal growth and management of strawberry in the greenhouse, 10%-20% of the irregular shaped fruit. The improper selection or ecological environment does not meet the fertility requirements of strawberries, often increasing the proportion of abnormal fruit, and some as high as 50%, resulting in reduced yield, low efficiency. Commonly shaped fruits include flattened fruit, fat fruit, aggregate fruit, and raised fruit. The reason for the abnormal fruit is the accumulation of virus and the degradation of species; the second is that the temperature of the shed is too low, the humidity is too high, the light is insufficient, and the lack of the number of unplaced bees or bees in the shed will cause poor fertilization; Third, base fertilizer was used as a fertilizer country, no organic fertilizer was applied, and topdressing fertilizer applied nitrogenous fertilizer, resulting in strong nutrient growth, excessive flower bud differentiation, and weak flower buds. Fourth, the temperature in the greenhouse was too high, and the film was not timely, or The soil is dry and the fertilizer is not balanced enough. The appearance of the strawberry is one of the symbols of the intrinsic quality, which directly affects the value of the commodity. In order to increase the total output of the strawberry, it is necessary to improve the environment, strengthen the management, and minimize the occurrence of abnormal fruit. First, select high-quality varieties and carry out configuration cultivation. For example, Jinxiang, All-Star, Hani, Fengxiang, Lihong, etc. Different varieties can be cultivated in the shed and branches can be interwoven to increase the rate of pollination and fertilization. Simultaneous detoxification. Second, organic fertilizers should be used as organic fertilizers in combination with inorganic fertilizers, especially with appropriate proportions of phosphorus and potash fertilizers. Third, during pollination, the temperature during the day is controlled at 25-28 OC, and it should be above 5 OC at night, and cannot be lower than 0 OC. At the same time, ensure that the humidity in the booth is around 40OC. 4. Put a box of bees in each half-acre shed to increase pollination and fertilization rates. Fifth, the application of pesticides to prevent pests and diseases should be carried out before the flowering peak, and to use high-efficiency low-toxic pesticides. The bees were moved out of the strawberry greenhouse when applied.
