Solanaceous vegetables preserved fruits and fruits

Solanaceous vegetables include eggplants, tomatoes, and peppers, and are vegetable varieties planted by vegetable farmers. In the process of flowering and fruiting, Solanaceae vegetables have different degrees of flowering phenomenon, especially in winter greenhouses. The reasons and preventive measures are now described as follows: 1. Causes of fruit drop and fruit drop of eggplant fruit Flower structure defects. This defect can be the original characteristics of the flower, it can also be in the flowering process, was affected by the external environmental conditions. If the short flower of eggplant can not be normal pollination, it will fall off. 2. No pollination or fertilization. Under normal conditions, the flowers of Solanaceous vegetables are not pollinated or fertilized and they are easy to fall off. Sometimes even if pollinated, it may not be fertilized and fall off. 3. Ovule degradation. After the ovule degenerates, the ovary does not expand normally and it falls off. 4. Too much or too little soil moisture. In flowering, if the soil lacks moisture, it will easily lead to the formation of layer separation; but the wintering cultivation of eggplant vegetables should be strengthened insulation, increase light, the more summer cultivation can be used two membrane technology, shade, shelter from rain, appropriate thin Planting, increase inter-plant permeability, flowering soil can not be dry, should not be flooded with water, air humidity can not be too high or too low, high temperature and dry or low temperature and high humidity and rainfall can cause drop and fruit drop. To ensure sufficient fertilizer and water, after the eggplant vegetables have been sitting in the first ear fruit, vegetative growth and reproductive growth are always carried out at the same time. If there is insufficient supply of vegetative growth in the plants, nutrient competition will occur between the organs. Cultivation can be through the sparse flowers and fruit, pruning squatting, picking the leaf topping and other measures to adjust the balance of its growth and development to reduce the falling fruit. two. Artificially assisted pollination. Shaking the plant can increase the selection of the appropriate concentration of pollination. Different types of vegetables have different sensitivity to growth regulators. Tomatoes are most sensitive and the concentration should be the lowest, generally 10 to 20 ppm. Eggplants are not very sensitive. The concentration should be appropriately larger, generally 20 to 50 ppm; different varieties of the same vegetable There are also differences between tomato and tomato. For example, all hybrids are more sensitive than conventional ones. When using growth regulators, the concentration should be reduced by half; the use concentration of growth regulators is also related to temperature, and the general temperature is high. Lower; low temperature, higher concentration; related to the growth of plants, plants grow more prosperous, especially the prosperous plants, the concentration is greater, when the plant growth is weak, the concentration should be smaller.
