Since the reform and opening up, people have been pursuing high-yield agriculture, using large amounts of chemical fertilizers and pesticides, resulting in soil compaction. The content of organic matter in the soil has declined, the development of crop roots has been hindered, and the growth has been slow. Rotten roots, dead seedlings, and diseases have often increased. The application of conventional low-toxic pesticides is difficult to solve, and the production is declining year by year, prompting producers to increase the amount of chemical fertilizers and pesticides. As a result, the content of nitrate and nitrite in the soil becomes higher and higher, resulting in a more compacted soil, forming a kind of Vicious circle. Excessive application of chemical fertilizers and pesticides undoubtedly bring about serious problems such as soil deterioration, declining product quality, and excessive food residue.
The rice does not taste fragrant, the vegetables do not have the fresh taste of the past, the fruits are not sweet, and the tea and tobacco are returned again and again due to excessive residue. The quality of the products cannot be brought into line with international standards, and agricultural products have been rejected due to quality problems. Large economic losses, this result can not participate in the global agricultural competition in the 21st century.
After China's accession to the WTO, people have higher and higher requirements for living standards and quality of life. They have a correct understanding of what is green, pollution-free, and organic food. They also have new concepts in production, management, and consumption. So far, the Ministry of Agriculture of the People's Republic of China has formulated production standards for agricultural products, banned the use of small amounts of fertilizers and pesticides, promoted the use of organic fertilizers, produced high-quality agricultural products, and expanded the international market.
At present, most of the farmers in China use organic manure to simply ferment organic matter such as livestock and poultry manure and straw. The level of composting technology is poor, and the fertilizer efficiency is low. It is even used without adequate decomposing, and burning and rooting often occur. In order to change this state and adjust the structure of the soil particles, it will play a decisive role in this regard; Darwin, a great biologist, said: “Plow†is one of the earliest human inventions, but far before humankind survives. The soil was ploughed by it and it was continuously cultivated by it. How many trips in his life can not be calculated, it is their endless movement, constantly eating soil, making the soil become soft and loose, the soil structure has been improved, become a regular group of large bodies. As a result of its own survival, it burrows holes and constantly eats soil. The soil that is eaten is excreted through the body's digestive treatment, increasing the effective composition of the soil by 2-3 times. If organic waste is used, it must be After fermentation, the proportion of maggots discharged after fermentation is 10-20 times higher than that of normal soil. According to relevant data, maggots contain not only a large amount of nitrogen, phosphorus and potassium but also other fertilizers. 18 kinds of amino acids, biochemical enzymes, antibiotics, growth factors, bacteria and actinomycetes and other nutrients. The use of alfalfa in agriculture is conducive to water conservation and conservation, increase soil fertility, and change soil aggregate structure. It is conducive to the development of roots and the absorption and utilization of phosphorus, and can effectively prevent the loss of ammonia and potassium, prevent the soil from being fixed by phosphoric acid, and keep the soil in a good state of air permeability for a long time. It can also be used for many years without ploughing.
Under the various effects of vermicompost, the crop makes its color more vivid, the leaves are greener, the fruit is fuller, and the individual weight of the fruits is increased and sweet and delicious. The quality of products has been greatly improved, and the products produced have become green and pollution-free organic foods.蚯蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 蚓 .
