The main reason for the emergence of fruit seeds in greenhouses was due to the failure of flower organs and fruits to develop normally. The development of a tomato as a normal fruit depends mainly on the quality of flower bud differentiation. Tomato fruits, especially the first and second panicles, are exposed mainly due to the high temperature or low temperature encountered during tomato transplanting. Usually when the tomato seedlings grow to 6 true leaves, flower bud differentiation of 1, 2, 3, and 4 inflorescences has been completed. When the flower buds of the inflorescences of the inflorescence differentiated into flowering plants at the seedling stage, if they encounter low temperature or high temperature, insufficient water, and too much nitrogen fertilizer, This will lead to over-differentiation of flower buds and the formation of multiple carpel malformation flowers. The resulting fruits will be deformed early. Sometimes in the nursery period or during the period of transplant due to low temperature or long duration of drought, low temperature, small temperature difference between day and night, nitrogen supply, seedling growth at inhibiting conditions, the flower easy to cork. When transferred to the appropriate conditions, the first formed cork tissue can not adapt to the rapid growth of the new internal organization, the formation of fruit cracks, pods, seeds and other fruits exposed to deformity. Control measures: 1. Select varieties that are not likely to produce deformed fruit, such as Hongyu, Hongbao, Xifen No. 3, Jiahong, Lichun and so on. 2. Reasonable use of plant growth regulators. When seedlings appear to grow in length, they cannot rely solely on water control and cooling to control seedling growth. Instead, they should spray “multi-purpose†200-times fluid or spray at a concentration of 0.01% on the basis of good temperature, light, and moisture regulation. Apply 25% of the booster to properly control the disease. 3. When watering the tomato, rush irrigation without deep ploughing, press the proportion of 30 ml plus 15 kg of water, flush with the water; also can be combined with topdressing organic fertilizer, add 30 grams of organic fertilizer with 50 grams of Angra granules to enhance The permeability of the soil enhances the ability of tomato to absorb and absorb water. 4. It is found that the exposed fruit should be promptly removed. To prevent the occurrence of malformed fruit, it is recommended to spray the available boron and Indian calcium mixture 600-800 times, spray once every 6 days, and spray 2 or 3 times in succession to prevent the tomato. Grain exposure has a good effect.
