Cherry Tomato cultivation: how to prevent Cherry Tomato from producing Hollow fruits?

How to prevent cherry tomatoes from producing hollow fruits? Please introduce the method the appearance and quality of cherry tomato products are particularly important, requiring the appearance and flavor of the products to meet the needs of consumers. In the production, the hollow fruit often affects the quality and weight of the fruit, reduces its commodity value, and causes greater economic losses. The formation of hollow fruit is due to the hypertrophy of core, placenta and gelatinous substance inside the fruit during fruit development, which is out of proportion to the hypertrophy of pericarp. The placental tissue of the fruit is separated, and a cavity is formed in the chamber, resulting in the appearance of the fruit with edges, the shape is not full, the ventricle is sunken, the pulp is less and the juice is light. Besides high night temperature, lack of light and close planting, the assimilation amount of cherry tomato decreased and the assimilation substance consumption increased, resulting in insufficient carbohydrates in the plant and inhibition of flower bud differentiation and development. It is also due to the insufficient application of nitrogen, phosphorus and potassium in the soil and the lack of fertility. In addition, improper application of auxin, high temperature in flowering and young fruit stage, excessive application of nitrogen fertilizer and too much water in soil are also the reasons for the formation of hollow fruit. The occurrence of hollow fruit is closely related to the maturity of seeds. in the process of fruit development, seeds play a role in making the fruit fat and full. if the cultivation mode, environment and other factors are suitable for the formation of seeds, the hollow fruit will decrease naturally. The key to solve the problem of hollow fruit is to create a suitable cultivation environment and cultivation method to make the seed develop completely. ⑴ variety selection. According to the cultivation season and cultivation mode, the suitable excellent varieties with strong stress resistance, good quality and good commerciality were selected. Strong seedlings were cultivated by ⑵. Strengthen the control of temperature, light, water, fertilizer and other environmental conditions to create external conditions conducive to plant flower bud differentiation. The key point of temperature management is the appropriate temperature difference between day and night, and pay attention to that the night temperature should not exceed 24-25 ℃, otherwise the quality of the flowers will be poor. It was kept at 25 ℃ during the day and 15-18 ℃ at night. There should be strong light and increase the duration of light. Fertilizer and water should be adequate, with 400 milligrams of nitrogen, 60 milligrams of phosphorus and 500 milligrams of potassium per kilogram. The water content should be fully watered to the degree that it does not cause the seedling to grow. ⑶ reasonable close planting. Cultivation density affects the development and nutritional status of seedlings, thus affecting the differentiation and development of flower buds. According to the characteristics of varieties and pruning methods, the suitable cultivation density was selected. Reduce the number of transplants, and do not hurt the roots as little as possible. ⑷ fertilized rationally. Give priority to base fertilizer, with little or no topdressing. The rational use of nitrogen, phosphorus and potassium can coordinate the vegetative growth and reproductive growth of the plant. The base fertilizer is mainly organic fertilizer, with 4000 kg of rotten manure, 40 kg of compound fertilizer and 30 kg of superphosphate per mu. ⑸ strengthens its management. Water management: under the premise of ensuring normal growth, water control is the main. Before flowering, the soil moisture should be kept at 65-75%, and the soil moisture should be kept between 75-85% during the fruiting period. Temperature management: to ensure a sufficient temperature difference between day and night, the night temperature should be lower in order to promote sugar conversion and reduce consumption caused by breathing. Especially about 10 days before flowering, the night temperature should be kept at 17 ℃, and the optimum temperature during flowering and fruiting period should be 23-26 ℃. Lighting: to increase the light intensity and prolong the light time, the appropriate light intensity is 40-50 000 lux. The leaves should be picked properly in the middle and later stage of growth to enhance the light and promote ventilation. If the light is not enough, the light can be replenished artificially. Fruit thinning and foliar topdressing can be carried out in the middle and later stage of growth. ⑹ was administered with hormone. When flowering and fruiting, it is necessary to improve the ability of pollination and fertilization as far as possible to form seeds, and artificial pollination can be carried out if possible. The application time and concentration of hormone are generally on the day of flowering or 1-2 days before and after flowering. The appropriate concentration is selected according to the temperature conditions and used in conjunction with cytokinins to promote the development of placental tissue.
