Malformed fruit is one of the most common problems in the process of planting sweet pepper. The main manifestation is that the fruit grows abnormally, looks like persimmon or peach, or the fruit is oblate or irregular, and there is almost no seed or seed dysplasia.
The malformed fruit is a physiological disease, mainly due to the bad weather conditions when the sweet pepper is differentiated or flowering, such as the temperature is too high or too low, the flower bud differentiation of the sweet pepper is poor, or the flower of the sweet pepper is poorly fertilized. Or it has not been completely developed. In general, if the sweet peppers that are planted in winter are too early to grow, they will not be able to sit in the autumn.
Prevention: 1. Pay attention to temperature control: When the sweet pepper is flowering and fruit setting in autumn, the temperature should not be too high. If the temperature in the greenhouse exceeds 35 °C: or 32 °C for more than 2 hours, the sweet pepper will have pollination or poor fertilization. . Before and after the Spring Festival, we should pay attention to avoiding the temperature and ground temperature in the greenhouse, affecting the sweet-skinned fruit, rushing the biological fertilizer of the Vodafone fungus and the biological fertilizer, and promoting the normal fruit setting of the sweet pepper.
2. Pay attention to fattening. The lack of boron, calcium and other elements in sweet peppers can lead to malformed fruit. Always pay attention to spraying foliar fertilizers or nutrient balance agents containing elements such as boron and calcium, such as foliar spray of green Fenwei 3 and boric acid or borax. Reduce the application rate of nitrogen fertilizer, increase the application rate of potassium fertilizer, such as potassium dihydrogen phosphate, potassium sulfate, etc., and timely spray the nutrient balance agent such as shellfish or sea power, which is conducive to fruit setting. Pay attention to controlling the growth of plants: the growth of plants is too high, and the probability of occurrence of deformed fruit will increase. The growth of sweet pepper fruits can be ensured by spraying growth regulators or pruning and snoring. If the sweet pepper can't sit on the fruit, it may cause the plant to grow too prosperously. It can spray the helper and regulate the normal growth of the plant through temperature regulation to facilitate fruit growth.
Under this category, the product of Wire Rope Clamp is mainly introduced. A wire rope clip, also called a clamp, cable clamp, wire rope clamp, U-Clip, U-Clamp, is used to fix the loose end of the loop back to the wire rope. It usually consists of a U-shaped bolt, a forged or cast saddle and two Nuts. The two layers of wire rope are placed in the U-bolt. The saddle is then fitted over the ropes on to the bolt (the saddle includes two holes to fit to the U-bolt). The nuts secure the arrangement in place.
