Fertilizer in vegetable field should control the amount of nitrogen fertilizer

Excessive nitrogen fertilizer application affects the quality of vegetables? A few days ago, the reporter consulted Zhang Guangming, director of the Institute of Vegetable Research of Shandong Academy of Agricultural Sciences.

According to Director Zhang, at present, vegetable farmers in our province often pay attention to the amount of nitrogen fertilizer used in vegetable production, while neglecting the application amount of organic fertilizer and seriously affecting the quality of vegetables. Therefore, it is necessary to appeal to vegetable growers to strictly control the amount of nitrogen fertilizer applied to vegetables in order to ensure the health of consumers, and to increase organic fertilizers to ensure the quality of vegetables.

There is a limit to the amount of nitrogen fertilizer applied to vegetables. It is not that the application is as good as possible. When it exceeds a certain amount, it will not only reduce the yield and quality of vegetables, but also cause environmental pollution.
