The recent response to vegetable farmers in the countryside has made the problem of premature vegetable decay more prominent in the production of large-scale vegetables in a year. According to the author's investigation, there are many reasons for causing premature aging of vegetables, and unreasonable fertilization is one of the important reasons.

If the excessive application of fertilizers causes capillary roots to be injured, no attention will be paid to balanced fertilization to cause the plants to grow too profusely or too weakly, leading to premature aging of the plants. Therefore, scientific and rational fertilization is an important measure to prevent premature aging of vegetables. Farmers should pay particular attention to the following points when fertilizing:

1. Spring warming, still can not arbitrarily increase the amount of fertilizer. Fertilization must be used rationally according to the fertilizer requirements of each crop, so as to avoid premature rooting of vegetables due to the excessive amount of chemical fertilizers causing root damage to vegetables. Generally, applying 15-20 kilograms of compound fertilizer with 30-40 kilograms of biological fertilizer is appropriate for every mu of land.

2. Pay attention to balanced fertilization. For example, if the amount of potash fertilizer is insufficient during the fruiting period of vegetables, not only the yield and quality of the vegetables will be affected, but also the premature aging of the plants will be caused. Therefore, fertilization must be based on a reasonable mix of fertilizer requirements for each growth period of the crop in order to ensure that the vegetables do not rest or age prematurely.

3. Avoid applying hormone-containing fertilizers. In particular, fertilizers that can be immediately found after application can often cause premature plant failure. When farmers purchase fertilizers, they must be cautious about selecting fertilizers of this type with “significant fertilizer effects”.

4. It is still necessary to pay attention to the application of biological fertilizers in spring. Biofertilizer has the function of improving soil structure, improving soil fertility, and inhibiting soil-borne diseases. It is undoubtedly a good fertilizer for maintaining plant roots and delaying plant senescence. It must pay attention to application in production.

5. Pay attention to the use of foliar fertilizers. Some foliar fertilizer can relieve the symptoms of deficiency of the plant. Frequent foliar spraying can obviously increase the growth of the plant, especially in the late stage of vegetable growth, which can significantly delay plant senescence.
