In order to prevent the disease in the lower part of the eggplant from continuing to grow upwards, many vegetable farmers have taken measures to reduce the pathogens by picking leaves. This is a good way to prevent the spread of diseases, but the authors found that some farmers have over-plucked leaves. To keep the whole plant only the top three or five leaves, this is often not worth the candle.
In the deep winter season, diseases in the leaves are severe. Some vegetable farmers have benefited from the removal of diseased leaves and old leaves in order to prevent diseases in the leaves. This can reduce the number of pathogenic bacteria on the lower diseased leaves, enhance the ventilation and light transmission between plants, reduce the occurrence of diseases, and is conducive to the growth of eggplant. However, many vegetable farmers do not have good control over the number of picking leaves. Too many leaves at one time affect plant growth and reduce yield.
The growth of eggplant fruits requires the consumption of large amounts of organic nutrients, which are mostly produced by the photosynthesis of the leaves. Organic nutrition is the basis of eggplant production and has a close relationship with the leaf area. To obtain high yields, a certain amount of blades must be guaranteed. Under normal circumstances, each branch of an eggplant has two fruits, one large and one small. The large fruit is in an enlarged period and consumes the most nutrition. The surrounding 3 to 4 leaves mainly supply the growth of eggplant; the upper leaves of the eggplant mainly supply the development of small fruits. Flower bud differentiation, new leaf growth; lower leaves, mainly to supply root growth. It can be said that each blade has its own responsibility. In order to prevent disease, some vegetable farmers have picked up the leaves around the big fruit, so that the root system must compete for nutrients with the fruit, which will obviously affect the yield.
Pick up the leaves to be divided, do not remove too much at once, so that the lower part of the plant becomes a light stalk. Eggplant grows less or does not hit the leaves in the early stage of growth, hit the bottom leaves, old leaves, and yellow leaves in the middle and late stages of growth; it has less fertilizer and water, and it is less prosperous to fight the leaves; In general, it is appropriate to retain 3-4 leaves in the lower part of the fruit.
