The exposure of tomato fruit in the greenhouse is a problem that many farmers and friends have headaches. Today, I would like to share with you the reasons for the exposure of the tomato fruit in the greenhouse and the prevention methods.
The reasons for the exposure of tomato fruit in the greenhouse and the prevention methods are as follows:
The reason why the tomato fruit in the greenhouse is exposed:
The appearance of fruit seeds in the greenhouse tomato was mainly caused by the inability of the flower and fruit to develop normally. Whether tomato can develop into normal fruit depends mainly on the quality of flower bud differentiation. Tomato fruit, especially the first and second ear fruits are exposed, mainly caused by high temperature or low temperature during tomato seedling transplanting. Usually, when the tomato seedlings grow to 6 true leaves, the flower bud differentiation of 1, 2, 3, and 4 inflorescences has been completed. When these inflorescences form flower buds at the seedling stage, if low temperature or high temperature, insufficient water, and excessive nitrogen fertilizer, That will cause the flower buds to over-differentiate, forming a multi-cardiac malformation flower, and the resulting fruit will be deformed in the early stage. Sometimes during the nursery or transplanting period, the temperature is low due to low temperature or drought, the temperature is low, the temperature difference between day and night is small, the supply of nitrogen is insufficient, and the growth of the seedlings is under the restraining condition. After being transferred to suitable conditions, the first formed corked tissue can not adapt to the rapid growth of new internal tissues, and then forms deformed fruits such as cracked fruit, capsule, and exogenous fruit.
Prevention and treatment of tomato fruit seed in greenhouse:
1. Use less likely deformed fruit varieties, such as ruby, ruby, West powder No. 3, good red Ponceau like;
2. Rational use of plant growth regulators. When the seedlings appear to be long, they should not rely on water control and cooling to control the growth of the seedlings. Instead, they should spray “multi-purpose†200 times liquid or spray at a concentration of 0.01% on the basis of temperature, light and water regulation. Apply 25% of the auxiliaries to properly control the wangwang;
3. When watering the tomato, apply the deep ploughing, according to the ratio of 30 ml plus 15 kg of water, with water; or combine with the application of organic fertilizer, each 50 kg of organic fertilizer with 30 g of Angri granules The permeability of the soil improves the water absorption capacity of the tomato;
4. It is found that the exposed fruits of the seeds should be removed in time. In order to prevent the occurrence of deformed fruit, it is recommended to spray the mixture of quick-acting boron and Indian calcium according to 600-800 times, spray once every 6 days, and spray 2~3 times continuously to prevent tomato. The appearance of the grain has a good effect.
