In long eggplant cultivation, the leaves and twigs of a part of the plant are removed to improve the light transmittance of the long eggplant and increase the temperature of the ground. Some long-growing solanes planted by growers are too sparse, and only a few leaves are left on the main branch, which seriously affects the growth of the plants and leads to poor plant growth.
1. Excessive picking of leaves, especially the removal of the fully developed leaves in the upper middle of the plant, will result in a decrease in the photosynthetic leaf area of ​​the plant, a decrease in the photosynthetic efficiency, and a reduction in the nutrients produced by the leaves, making the speed of the fruit bulking slow and easy. Malformed fruit. At the same time, the fruit is exposed to direct sunlight for a long time and it is also prone to yellowing of the peel, which affects the fruit's commercial properties.
2. When sparse leaves are removed together with some side branches, only some of the leaves are long on the main branch, which results in the growth of the main branches of the leaves, which makes it easy to prosper, and the stems are weak. At the same time, because of the lack of nutrients produced by the leaves, the lateral branches of the plants are not adequately nutritious, the resulting ability of the lateral branches is reduced, the deformed fruits are increased, and the yield and quality are reduced.
Therefore, in the long fruiting period, the leaves must be shredded and the snoring must be moderate, and must not be taken too much. In the process of leaf thinning, for the leaves on the main branch, leave 1-2 leaves on the bottom of the lowermost fruit. The remaining lower leaves should be completely removed. Do not remove the leaves from the upper middle part of the plant; The side branches that have already resulted are left with two leaves in the upper part of the fruit.
