Since the development of organic agriculture in China is not yet complete, and the development of organic fertilizer sources is relatively small, it is necessary to strengthen this technology, and now people have less understanding of organic fertilizers, and then ignore the organic fertilizer in agricultural production. Therefore, the following article will specifically talk about the fertilization and soil fertility techniques of organic farming, and I hope that it will help everyone.

1. Expand the source of organic fertilizer and increase the input of organic fertilizer

In recent years, China's organic fertilizer organic fertilizer sources are small, the input and the proportion of the decline are obvious, and the application in agricultural production is relatively small, so people's awareness of the use of organic fertilizers, the expansion of organic fertilizer sources, and the increase of organic fertilizers are increased. The quantity has become the top priority in the current organic agriculture soil cultivation process.

1.1 Expanding the area of ​​green manure planting

Green manure has become the first choice for organic fertilizer in the development of organic agriculture because of its variety and easy cultivation. Green manure is a kind of nutrient-rich biological fertilizer source. Scientifically and rationally selecting green manure varieties and maximizing the yield per unit area is not only The limited path of over-fertilizer plays a major role in improving soil.

1.2 Rational use of animal and plant fertilizer sources

The combination of crop straw and animal manure is an excellent source of organic fertilizer, which is widely used in topdressing. However, human urine contains salt and has less organic content. Therefore, humans should be first Urine and plant straw are thoroughly mixed and put into use to increase the content of organic components.

2. Improve the cultivation technology of organic agriculture soil

Increasing the source of organic fertilizer is the basis for the cultivation of organic agriculture soil. At the same time, mastering the professional cultivation technology is the foundation of organic agriculture soil cultivation. Scientific and rational cultivation technology can achieve twice the result with half the effort for promoting the growth of crops and promoting the development of organic agriculture in China.

2.1 Fertilization according to the characteristics of organic matter

Organic fertilizer is the most widely used and safest fertilizer in organic agriculture cultivation, but it needs to be different depending on the crop during the fertilization process. According to the different nutrient requirements of crops and the characteristics of organic matter, scientifically select different fertilization techniques and organic matter content. At the same time, the type and quantity of fertilization have a huge impact on the yield of crops. The yield of crops is also greatly affected by the time of fertilization. The fertilization and the amount of fertilization and the maximum efficiency of nutrient are grasped.

2.2 Fertilization according to soil properties

The growth of crops is affected by various factors in the soil, such as water, humidity, temperature and salinity in the soil. Different soils contain different water, temperature, fertility and other factors. Different crops The demand for soil and the absorption of nutrients in the soil are not the same, and the difference in the type and quantity of nutrients in different soils. Therefore, the type of soil should be paid more attention to during fertilization. For soils that are loose and nutritious, nutrients are easily lost, and nutrients need to be replenished in time.

2.3 Fertilization according to crop types and their growth patterns

Different types of crops have different nutrient requirements and different ways of absorbing nutrients. At the same time, the demand for nutrients in different growth periods is also different. Therefore, it is necessary to grasp the types and growth laws of crops, and carry out scientific and effective fertilization according to the growth law. It will do more with less.

2.4 Reasonable tillage to improve soil fertility

The benefits of rational farming mainly include improving the soil environment, promoting the circulation of water, air, fertilizer and sunlight, facilitating the growth of roots and the free conversion of organic matter, and improving soil fertility. At the same time, it is necessary to strengthen irrigation and increase soil moisture content. Enhance soil fertility.
