Protection of vegetables in the five taboos

Avoid excessive fertilization due to high temperature in the greenhouse, high humidity, rapid decomposition of organic fertilizer, phosphorus is 2 to 3 times higher than the exposed ground, oxygen volatilization is large, excessive fertilizer can easily cause fertilizer damage. Therefore, for greenhouses planted for more than three years, the amount of chicken manure applied should be controlled within 2,500 kilograms, and chemical fertilizers should be reduced by about 50%.

Avoid excessive temperatures Some growers mistakenly believe that a high temperature dish grows quickly. In fact, an excessively high temperature will inhibit the growth of young fruit and lead to fruit faults. It will have large respiration, body movements and physiological activities, and the body will grow in length. The growth of plant vines and reproductive growth will be unbalanced. The output will not only increase, but will decrease. Some varieties Even light does not grow fruit.

Do not keep the seedlings too dense. According to the determination, 2 square meters of tomato planted on 1 square meter, 50% of the photosynthetic product will be consumed by its vegetative body, and the other 50% will affect fruit growth. If 4 plants are planted per square meter, the vegetative body will consume 70% to 80% of the photosynthetic product, and only 26% to 30% for fruit growth.

Avoiding drug fights. Many vegetable farmers fight drugs once every 3 to 3 days in the middle of growing vegetables. They believe that drugs can be used to prevent the spread of diseases. Actually, when drugs are administered during this period, it will not only interfere with the normal synthesis of carbohydrates, but will also be detrimental to the production of antibiotics in plants, thus reducing the resistance to diseases.

Avoid too many times Some farmers mistakenly believe that more than one income. In fact, the more times of planting, the worse the effect and the lower the benefit. Generally, it is better to spend 1 year and 1 year for wintering and 1 year and 2 days for spring and autumn. The eggplant, pepper, tomato, and cucumber can be recycled for 1 year at low prices.
