First, the cause of fat damage
1. Blind application of nitrogen fertilizer: In production, people always think that crops have a large demand for nitrogen fertilizer. Therefore, once the crops are poorly grown, they will not ask for defects, all nitrogen will be applied, and more nitrogen fertilizer will be applied more, resulting in excessive nitrogen fertilizer and fat damage. . In particular, the application of volatile nitrogen fertilizers, such as ammonium bicarbonate and ammonia water, can easily cause crop damage; excessive application of nitrogen fertilizer can also cause plant nitric acid accumulation and yellowing of leaves. Excessive application of nitrate nitrogen fertilizer can easily cause chlorosis and deficiency of molybdenum in crops.
2. The amount of application is too large: the excessive application of chemical fertilizer or human and animal excrement will cause the soil fertilizer concentration to be too high, so that the roots of the crop will absorb nutrients and water, and the fat will occur.
3. Applying unfertilized organic fertilizer: Undecomposed organic fertilizer will produce a large amount of organic acids and heat during the decomposition process, which may cause rooting.
4. The topdressing is too close to the root of the crop: because the chemical decomposition is fast and high, the fertilizer is too close to the root system to cause fertilizer damage.
Second, preventive measures
1. No organic fertilizer is applied: organic fertilizer must be fermented and then applied, especially after the poultry manure is fermented and mixed with chemical fertilizer.
2. Rational use of chemical fertilizer: the use must be measured first and applied according to the concentration, especially the nitrogen fertilizer can not be too much at a time. The concentration of foliar spray should not be too high. Urea should be used as foliar fertilizer. The concentration should not exceed 0.3%.
3. Adding organic fertilizer: The organic fertilizer applied to the soil has a strong adsorption capacity for the cation, so that the concentration is not too high, and the buffering capacity of the soil nutrient is improved, which can greatly reduce the occurrence of fertilizer damage.
4. Fertilization should be about 10cm from the root of the crop, and it should be applied deep. Immediately after top dressing, cover the soil to prevent seedling stage burning and loss of fertilizer efficiency. Soil drought and topdressing need timely irrigation, reduce concentration, and avoid burning phenomenon.
