How to prevent fertilizer damage
First, the causes of fertilizer damage 1. Blind manure application. In production, people always think that crops have a large demand for manure, so if the crops are not growing well, they will not ask questions and they will all be used. As a result, more and more fertilizers are applied, resulting in excess fertilizer damage. In particular, the use of volatile nitrogen fertilizers, such as ammonium bicarbonate and ammonia, can easily lead to crops suffering from fertilizer damage; excessive use of nitrogen fertilizers can also cause nitrite accumulation and yellowing of the plants. Excessive use of nitrate nitrogen fertilizers can easily lead to crop loss of green molybdenum. 2. The amount of topdressing is too large. Excessive application of chemical fertilizers or manure urine at a time will result in excessively high soil nutrient concentrations, which will lead to nutrients and moisture in the roots of the crops. 3. Apply unfermented organic fertilizer. Uncooked organic fertilizers produce large amounts of organic acids and heat during the decomposition process, which can easily cause burning. 4. The top dressing is too close to the root of the crop. Due to the fast and high fertilizer efficiency of chemical decomposition, it is easy to make crops produce fertilizers because the top dressing is too close to the root system. Second, preventive measures 1. No organic fertilizer applied. Organic fertilizers must be decomposed before they are applied. In particular, poultry manure must be fermented with organic fertilizers and fertilizers. 2. Use chemical fertilizers rationally. The use must be measured first and then applied according to concentration and concentration. In particular, nitrogen fertilizer should not be excessive at one time. Foliar spraying concentration should not be too high. For urea, the concentration of urea should not exceed 0.3%, and it can be sprayed wet. 3. Add organic fertilizer. The organic fertilizer applied to the soil has a strong adsorption capacity for cations, so that the concentration is not too high, and the buffer capacity of soil nutrients is increased, which can greatly reduce the occurrence of fertilizer damage. 4. Fertilize about 10 centimeters away from the root of the crop and deepen it. Immediately after dressing, cover the soil to prevent seedlings from burning and losing fertilizer. Soils are topdressed in dry conditions and must be promptly filled with water to reduce the concentration and avoid burning.
