Nowadays, the pollution of chemical fertilizers has become one of the public pollution in the world. According to the “2010-2015 China Chemical Industry Investment Analysis and Prospect Forecast Report” issued by China Investment Consultant, in the northeast black soil area of China, due to the long-term application of chemical fertilizers, the organic-rich soil from the beginning has been transformed into the current organic poor soil. Soil organic matter is 8-10% at the time of reclamation and has now fallen to 2-3%. In other regions, the reduction of soil organic matter is even more serious.
Chang Yizhi, a researcher in the chemical industry of China Investment Consulting, pointed out that as far as the soil resources in China are concerned, the application of traditional organic fertilizers has been greatly reduced due to the long-term application of chemical fertilizers. The proportion of nutrients contained in the soil is out of balance. The ecological environment of farmland in China, the microbial environment of soil and the physical and chemical properties of soil have been damaged to varying degrees. The yield and quality of crop products have declined. Therefore, some measures need to be taken to supplement the organic matter in the soil and improve the yield and quality of the product. Bio-organic compound fertilizer has been favored by people because it can provide rich nutrients and good living environment for the soil where crops grow and reproduce.
According to the “2010-2015 China Chemical Industry Investment Analysis and Prospect Forecast Report” issued by China Investment Consultant, bio-organic compound fertilizers are combined with organic fertilizers and inorganic fertilizers, containing nitrogen, phosphorus, potassium, sulfur, calcium, silicon, magnesium , a variety of nutrients necessary for crops such as iron and zinc. It also contains 15% to 30% organic matter and contains various microbial components and high-energy compounds. In production and use, the effect is very obvious. It not only improves the physical and chemical properties of the soil, but also enhances the resilience of the crop. The quality of crops has also been greatly improved. For example, the sweetness of fruits such as watermelon, sugar cane and strawberry is very obvious. Moreover, it can promote the increase of crop yield, which is about 10% higher than that of single application of fertilizer. It can even improve the ecological environment of farmland. The advantages of bio-organic compound fertilizers are obvious.
Chang Yizhi believes that although bio-organic compound fertilizer has many significant advantages, due to the relatively high price, the promotion of bio-organic compound fertilizer is not enough. People have not used it universally because of the improper use of the fertilizer. There are also large differences in the use of localities, and the market share is limited. Therefore, in order to improve the status quo of China's soil as soon as possible, so that the fertilizer efficiency of bio-organic compound fertilizers is brought into play, relevant departments should take measures to solve these problems as soon as possible. For example, the use of organic raw materials on site reduces production costs, thereby reducing market selling prices. Increase publicity and increase people's awareness of using bio-organic compound fertilizer. Organize science and technology to go to the countryside to teach people how to use them properly, so that the fertilizer efficiency of bio-organic compound fertilizer can be better played.
Zhang Yulin, research director of China Investment Consulting, pointed out that bio-organic compound fertilizer is composed of organic fertilizer, inorganic fertilizer, biological fertilizer and synergist. It has the characteristics of various fertilizers. It is highly efficient and pollution-free, and is an environmentally friendly fertilizer called green fertilizer. It is a new trend in the development of the fertilizer industry. At present, the Ministry of Science and Technology and the Ministry of Agriculture have already promoted bio-organic compound fertilizers throughout the country, and it has great room for development in the future.
