With the continuous increase of product functions, the performance of glass greenhouses has been recognized by everyone. Everyone knows that although the greenhouse has a good constant temperature effect, there are still many precautions for fertilization in the greenhouse. Many people may not know how to fertilize glass greenhouses in winter. Next, let's get to know each other in detail.
1. To master the application rate of nitrogen fertilizer. After all, it's fertilizer. In order to ensure the normal growth of vegetables in a glass greenhouse, it is also necessary to control their dosage.
2. Try not to use chlorine fertilizer. Excessive chloride ions in fertilizers may lead to sugar content in vegetables, worsening their taste and affecting their quality.
3. The use of ammonium carbonate is prohibited. This type of fertilizer is prone to volatilizing a large amount of ammonia gas, and excessive ammonia gas can cause ammonia damage, which is harmful to the human body and not beneficial to vegetables.
4. Prohibit the application of nitrate nitrogen fertilizers. Nitrate containing fertilizers and compound fertilizers only accumulate more nitrate in vegetables. Once a person eats this vegetable, it will be reduced in the body and converted into nitrite. Nitrite is a carcinogen, which may cause gastric cancer and other diseases.
Through the introduction of the precautions for applying fertilizer in the glass greenhouse in winter, we should use these fertilizers carefully. We can use green ecological organic fertilizer, which can not only improve the soil and soil fertility, but also prevent hardening. I hope this explanation can be helpful to you.
