Symptoms of premature aging of vegetables such as eggplant, pepper, and tomato are atrophy, slow growth, yellowing of leaves, and late flowers and fruits, low yield, and poor quality. In severe cases, plants wither prematurely and die, and respond to the disease to take effective measures.
Scientific fertilizer. Ru fruit is a crop that requires more fertilizer and consumes more quickly. To ensure nutrient requirements, it is necessary to apply enough base fertilizer to guarantee supply, especially for the seedling stage, flowering stage, maturity stage, and after the fruit is harvested for the first time. 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. Ru fruit grows strongly and has many collaterals. It is necessary to pick up the heart in a timely manner during vigorous growth to promote early maturity. After harvesting the first loquat fruit, the top heart and the side heart should be removed at appropriate times to eliminate the “apparent dominance†and promote plant balance. Grow.
Prevent pests and diseases. In the middle and later stages of the growth of the ruguo vegetables, serious pests and diseases are a serious factor in causing premature aging of the ruo fruit. Strengthen the management of pests and diseases, can extend the growth period of fruits and increase production. The common diseases and pests of ru- fruit vegetables include epidemics, powdery mildew, viral diseases, anthrax, downy mildew, gray mold, aphids, and red spiders. 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, no spraying can be performed on the required number of days before harvesting.
Harvested in time. Ru fruit vegetables have high yield and fast growth, but too many results will result in falling flowers and falling fruit, premature aging in the late growth period, and timely harvesting, which can reduce the burden on the plants and reduce the number of fruit and fruit. Eggplant green peppers can be harvested at eight ripenings, and tomatoes can be harvested when they are ripe at nine, and red peppers can be harvested when they are reddish.
