Treatment methods of excessive Application of nitrogen Fertilizer in Rice

Nitrogen fertilizer is one of the indispensable elements in the growth of rice, it can promote the growth of rice and improve it, but we all know the meaning of going too far. If too much nitrogen fertilizer is applied, it will only cause damage to rice. So how to deal with the excessive application of nitrogen fertilizer in rice? Let's take a look at the detailed introduction.

First, the harm of excessive application of nitrogen fertilizer

The harm of excessive application of nitrogen fertilizer is great, and the harm of each growth stage is also different. if too much nitrogen fertilizer is applied at the tillering stage of rice, the growth of the root system is too prosperous, and the root system grows slowly, which will make the rice root unable to provide sufficient nutrients during tillering. Cause shrunken grains. If too much nitrogen fertilizer is applied in the growing period, the plant will grow luxuriantly, but the stem is weak and the plant is too high, resulting in concealment in the lower part, high temperature and humidity, easy to breed diseases and insect pests, lodging in the later stage, seriously affecting the yield and no harvest in serious cases. Excessive application of nitrogen fertilizer will not only lead to poisoning caused by the accumulation of nitrate nitrogen in rice, but also increase the protein content of rice, which will affect the taste of rice.

2. Treatment methods

1. Excessive application of nitrogen fertilizer is easy to cause premature senility, which can be sprayed with potassium dihydrogen phosphate, which can not only increase production but also prevent premature senility. Generally, 100-200 grams of potassium dihydrogen phosphate is sprayed with 15-20 kg water at booting stage and heading stage. This has an obvious effect on the seed setting rate and grain weight of rice, because it is a high concentration spray, so it is recommended to use high purity potassium dihydrogen phosphate, not to use potassium dihydrogen phosphate with more impurities, so as not to affect the effect.

2. We should pay attention to the application of silicon fertilizer to enhance the lodging resistance of rice, if possible, we can apply it 1-2 times properly to enhance the lodging resistance of rice, especially in the fields near the lake and sea, the wind is strong, lodging resistance prevention is necessary.

3. The prevention and control of diseases and insect pests must be in place. When spraying potassium dihydrogen phosphate, it can be combined with benzoconazole to prevent rice false smut and sheath blight. If it is a variety infected with rice blast, tricyclazole or pyrazole can be added.
