The recent discovery of the countryside, the problem of premature aging in the production of large-scale vegetables for a year is quite prominent. There are many causes of premature aging of vegetables, and irrational fertilization is one of the important reasons. For example, excessive application of chemical fertilizers may cause damage to the capillaries and injuries, and the lack of attention to balanced fertilization may 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 warmer, still can not arbitrarily increase the amount of fertilizer. Fertilization must be rationally used according to the fertilizer requirements of each crop, so as to avoid root damage caused by over-concentration of chemical fertilizers, which may lead to premature aging. Generally, it is advisable to apply 15-20 kilograms of compound fertilizer with 30-40 kilograms of biological fertilizer per acre.

2, 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 production period of the crop in order to ensure that the vegetables are not restless or premature.

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, still need to pay attention to the application of biological fertilizers in the 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 fertilizer. 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.
