Organic fertilizer is a very important fertilizer in agricultural production, which runs through the beginning and end of agricultural production. In recent years, with the requirements for new agriculture, green, efficient, healthy and environmental protection, organic fertilizers have gradually replaced chemical fertilizers. The application of organic fertilizers in agricultural production not only improves the safety of agricultural products, but also promotes the efficiency of agricultural production to a certain extent. Contrary to chemical fertilizer, organic fertilizer can effectively balance soil nutrients and maintain ecological balance. Moreover, perennial application of organic fertilizer can improve soil and enhance soil fertility. It is hoped that agricultural workers can pay attention to the use of organic fertilizer.

First, the role of organic fertilizer

1. The effect of organic fertilizer on soil

The use of organic fertilizers for soil is very obvious. Soil is the base and carrier of crop production. Soil nutrient supply directly affects the quality and efficiency of crop production. Firstly, the application of organic fertilizer can increase soil aggregates and reduce soil bulk density. And through the experiment, the use of organic fertilizer can enhance the water retention capacity of soil, increase the water content of soil.

Secondly, the long-term application of organic fertilizer can effectively improve soil nutrients and enhance soil fertility. The application of organic fertilizer can not only improve soil physical properties, but also improve soil chemical properties. According to the survey, the application of traditional organic fertilizers can effectively increase the nitrogen content of soil and enhance the soil support. Thirdly, compared with chemical fertilizers, organic fertilizers can greatly increase the content of soil organic carbon pool under the condition of the same amount of use, and long-term application of farm manure combined with chemical fertilizers can effectively increase the content of soil available phosphorus. Fourth, the effective use of organic fertilizers can balance the PH and conductivity of the soil. According to the data, the long-term application of organic fertilizer, compared with the application of chemical fertilizer, can improve

Raise the PH of the land, reduce the accumulation of soil surface salt precipitate. Fifth, the application of organic fertilizer can balance the microorganisms in the soil, so that the soil can achieve the most vigorous metabolism, suitable for crop growth. According to the survey, long-term application of organic fertilizer can effectively increase the number of actinomyces and nitrifying bacteria in soil. Sixth, compared with chemical fertilizers, organic fertilizers can reduce the pressure of heavy metals on the soil. It is not because organic fertilizers contain heavy metals, but because the heavy metal elements in organic fertilizers have biological availability, which can effectively destroy heavy metals in soil, promote the growth of agricultural crops and reduce heavy metal pollution in soil. Moreover, according to the data, appropriate combination of organic fertilizers and chemical fertilizers can reduce the damage of heavy metals in soil. Reduce the damage to ecological balance. Finally, compared with chemical fertilizers, organic fertilizers have strong adsorption power, which can effectively adsorb residual pesticides and harmful substances in the soil, which is conducive to the maintenance of ecological environment.

2. The effect of organic fertilizers on crops

In the growing process of crops, a large amount of nutrients are needed. The use of organic fertilizer can perfectly provide nutrients for the growth of crops, so as to improve crop yield and promote the healthy growth of crops. According to the survey, the combination of organic fertilizer and inorganic fertilizer with scientific methods can effectively improve the production efficiency and yield of rice. Compared with the single use of organic fertilizer or inorganic fertilizer, the rice yield can be increased by 2%-11%. According to agricultural experts, the combined use of organic fertilizer and chemical fertilizer can promote the growth of rice and increase the 1000-grain weight under the same amount of nutrients. The combined use of organic fertilizer and chemical fertilizer is not only effective for rice production, but also can effectively improve the yield of corn and winter wheat, and promote the development of Chinese agriculture. The focus of the use of organic fertilizers is to effectively improve the quality of crops. The gene expression of agricultural products is reflected by quality, and the use of organic fertilizers can affect the gene expression of agricultural products. According to scientific investigation, the combination of organic fertilizer and chemical fertilizer can improve the growing environment of crops and improve the quality of crops. For example, in Mr. Shen's

In the mixed application of organic fertilizer and urea, the experimental results clearly reflected the influence of the mixed organic fertilizer and urea on the content of sugar and vc in watermelon. The sugar content in watermelon was significantly increased, and the nutritional value of watermelon was also improved compared with the application of traditional fertilizer. In addition, in Teacher Zeng's rice experiment, it can be clearly found that the combined use of organic fertilizer and chemical fertilizer can improve the edible taste of rice and enhance the nutritional value of rice.
