Is it better to grow rice with organic fertilizer or chemical fertilizer? Which can increase production?

Organic fertilizer is a kind of fertilizer formed by mixing biological raw materials with water and soil, or mixing animal manure with green plants for fermentation. Organic fertilizer has the advantages of slow release of fertilizer, rich and colorful organic matter, no caking, no damage to crops, and enhanced plant resistance to pests and diseases. More importantly, agricultural products produced by grain crops grown with organic fertilizer are safe for human body. Therefore, in our life practice, we advocate using a lot of farmyard manure and using less excessive residual organic fertilizer.

Generally, we call farmyard manure organic fertilizer. This fertilizer is characterized by rich and comprehensive nutrients, which can improve the soil and meet the needs of rice growth and development. However, the effect of organic fertilizer is slow, and the single application of farmyard manure can not meet the fertilizer supply in the rapid growth period of rice. Therefore, although the quality and taste of rice fields with only farmyard manure are suitable, the commodity rate of rice ears is often low, which leads to limited agricultural production.

Organic fertilizer has comprehensive nutrients, slow digestion and absorption of crops and long duration. It can improve the stress resistance of rice, improve soil, avoid water pollution and transform nutrients that cannot be absorbed in soil. General farmyard manure belongs to the category of organic fertilizer, but the disadvantage is that the nutrient transformation is slow and the effect of promoting production is not obvious. Because of its characteristics, organic fertilizer has the advantages of fast absorption, short duration, excessive application, obvious soil accumulation, relatively single nutrient elements, great harm to the environment, serious soil agglomeration, alkalization, salinization and serious water pollution.

Rice growth and development needs not only water-soluble fertilizers such as light fertilizer, but also other nutrients such as zinc, boron, calcium and sulfur. General farmyard manure, soil mixed manure and green manure crops or products organic manure are all called organic manure. Compared with organic fertilizers, they contain a lot of organic matter, which is not only comprehensive in nutrition, but also durable in fertility, so the quality of rice is very good. Only a large number of light fertilizer nutrients necessary for rice growth and development can not be met, which is harmful to rice production. Even if a large number of organic fertilizers are used, the general yield is not ideal, even.
