How to prevent fertilizers premature aging vegetables?

Lead to premature aging of vegetables for many reasons, including unreasonable fertilization is one of the important reasons. How to prevent fertile vegetables to prevent premature aging it? Here to tell you about preventing premature aging vegetables fertilization methods.

Premature aging vegetables

Fertilizer topdressing caused by capillary root injury, do not pay attention to balanced fertilization caused by excessive or weak plant growth, etc., may lead to plant premature aging. Therefore, scientific and rational fertilization is an important measure to prevent premature aging of vegetables. Friends of farmers in the fertilization should pay attention to the following questions:

1. Spring pick-up, still can not increase the amount of fertilizer. Fertilization must be based on the law of need for fertilizer for each crop to be used reasonably to avoid vegetable root injury caused by over-fertilization of chemical fertilizers, leading to premature aging of plants. General topdressing of 15-20 kg of compound fertilizer per acre with bio-fertilizer 30-40 kg is appropriate.

2. Pay attention to balanced fertilization. Such as the lack of potash fertilizer peak results, not only will affect the yield and quality of vegetables, can also cause premature plant failure. Therefore, fertilization must be based on the needs of each crop growth period of the fertilizer needs a reasonable match, in order to make the crop without stubble, no premature decline.

3. Avoid the application of hormones containing fertilizers. In particular, immediately after the application of fertilizer can often lead to plant premature aging. Farmers in the purchase of fertilizer, such "fertilizer is particularly significant" fertilizer must be carefully selected.

4. Spring still pay attention to the application of biological fertilizer. Due to the improvement of soil structure, soil fertility and the suppression of soil-borne diseases, bio-fertilizer is undoubtedly a good fertilizer for curing plant roots and delaying plant senescence. In the production, biological fertilizers must pay attention to cooperation.

5. Pay attention to the use of foliar fertilizer. Some foliar nutrients can alleviate plant deficiency symptoms, often foliar spray can significantly improve plant growth, especially in late vegetable growth, can significantly delay plant aging.

The above is to prevent premature aging fertilization of vegetables introduction, farmers friends in the fertilization time, you can refer to the above methods, combined with the actual planting situation, according to local conditions, a reasonable fertilization.
