After the tomato grows and develops into flowering fruiting period, the phenomenon of flower and fruit shedding often occurs to varying degrees, which brings disadvantage to the improvement of tomato yield and quality. Why do tomatoes fall and fall, how to prevent it? Let's talk about this issue below.
First, the cause of tomato drop and fruit drop. (1) Low temperature and rain. The optimum temperature for the tomato flowering period is 25-28°C. When the temperature drops below 15°C, the pollen germinates badly, and when it drops below 10°C, it causes poor fertilization, and the lack of flower growth hormone causes a large number of flowering. At the same time, if the flowering period of the tomato meets the long-term low temperature and rain, the sunshine is insufficient. On the one hand, the rain showers on the flowers, the organic matter cannot be produced through normal photosynthesis, and the flower development is bad and the flowers fall and fall. On the other hand, when the temperature is low and rain is cloudy, the air humidity is high, and the pollen grains bulge excessively and burst, and pollinating ability is lost, resulting in falling flowers. (2) High temperature and drought. The fruiting period of tomato flowering is very sensitive to moisture, and the soil is too dry, especially if it is wet and dry or the plant loses too much water in a short time, the growth is not good, and the pollen loses water and infertility causes flowering and fruit drop. In addition, the tomato flowering results in summer and hot weather, sometimes at noon temperatures of up to 30-40 °C and even more than 40 °C, then particularly prone to high temperature burns, pollen abortion, flowers shrinking and falling. (3) Insufficient nutrients. After the tomato enters the flower and fruit stage, the demand for various nutrients such as flowering, bud formation, fruit setting and fruit growth and development reaches a peak period. If there is insufficient supply of nutrients at this time, there will be a drop in fruit. Malnutrition can also affect the normal development of flower organs and fruits. If pollen is small and the style is uneven, it cannot be normally pollinated and fall off.
Second, to prevent tomato drop and fruit falling measures. To prevent tomatoes from falling and fruiting, we must do the following work on a targeted basis on the basis of timely sowing, cultivation of strong seedlings, rational close planting, scientific fertilization, and strengthening the plant's resistance to stress. (1) To improve the temperature and humidity conditions during the flowering and fruiting period of tomato. Anti-low temperature in spring, anti-high temperature or drought in summer and autumn, timely irrigation and drainage, keep the ground dry, high temperature when the spray mist spray to protect the flowers and protect the fruit. (2) To ensure nutrient supply during flowering and fruiting of tomato. Fertilizer in the middle and after the application of the foliar spray fertilizer is good, such as spraying fruit 0.2-0.3% of potassium dihydrogen phosphate. For those who have obvious signs of premature fertility due to lack of fertilizers, it is necessary to make timely use of quick-acting fertilizers. (3) timely chemical regulation. The most effective and effective pharmaceutical agents are Tomato Spirit and 2.4-D. Tomato Spirit is used at a concentration of 20-40 mg/kg, usually 25 to 30 mg/kg for spray, dipping flowers, 30 to 35 mg/kg for pedicels, and 35 to 40 mg/kg for low temperature in spring. Anti-heating with 25 mg/kg. 2.4-D use concentration of 10 ~ 20 mg / kg, the high temperature season or dip flower or spray concentration is slightly lower, on the contrary slightly higher, but pay attention to prevent injury.
