The common symptoms of premature aging of eggplant, pepper, tomato and other vegetables are atrophy of the plant, slow growth, yellowing of the leaves, late flowers and fruit, low yield, poor quality, severe plant death with premature wilt, response to the disease, take effective measures to deal with.
The scientific use of solanaceous fruit vegetables is a crop that requires more fat and less fertilizer. In order to ensure the nutrient needs, sufficient supply must be applied to guarantee the supply of nutrients, especially at the seedling stage, flowering stage, maturity stage, and after the fruit is harvested for the first time. To top-dressing. The combined application of nitrogen, phosphorus, potassium and trace elements (boron, calcium, zinc, iron) has a good effect on the regeneration of plants, the increase of second crop yield, and the prevention of premature aging. In the middle and late stages, extra-root fertilizers can also be conducted.
Timely pruning Solanaceous vegetables have strong growth potential and many lateral branches. They need to be picked in due time during the vigorous growth period to promote early maturity. After the harvest of the first crop, the top heart and side hearts should be removed timely according to the density to eliminate the “apparent dominanceâ€. Promote balanced growth of plants.
Prevention and control of diseases and insect pests Solanum vegetans During the middle and late stages of growth, serious pests and diseases are an important factor in the premature decline of Solanum vegetables. Strengthening pest and disease management can extend the growth period of solanaceous vegetables and increase yield. Solanaceous vegetables have common diseases such as disease, powdery mildew, viral disease, anthrax, downy mildew, gray mold, aphids, and red spider. Drugs should be used for prevention and treatment in time, but special caution should be exercised when using drugs. High-toxic pesticides with long-lasting residual effects are strictly prohibited to ensure the safety of people and animals. Regardless of pest control or treatment, it is not possible to spray medicine on the required number of days before harvesting.
The timely harvest of solanaceous vegetables has high yield and rapid growth. However, if there are too many fruits on the stem, it will cause flowering and fruit falling, premature aging at the late stage of growth, and timely harvesting, which can reduce the burden on the plants and reduce fruit drop and fruit drop. Eggplants, green peppers can be harvested at eight ripening, tomatoes can be harvested at nine when ripe, red pepper can be harvested when the red color.
