Fertilizer is often used in our daily production and life, so what are the problems faced by the utilization of Fertilizer in China's planting and breeding industry? Let's see together.
Here is the content list:
l The total amount of waste resources is unclear, and the collection and storage system needs to be improved urgently
l Insufficient innovation in waste Fertilizer technology and equipment, and a lack of supporting agricultural technology
l The quality of waste Fertilizer sources is uneven, and the quality of organic Fertilizers and market competitiveness are insufficient
The annual amount of waste generated by China's planting and breeding industry, its treatment method, and its final trend is still unclear. Most of the data are obtained through estimation, and there is a lack of information on the distribution, utilization status, utilization scale, and environmental impact of these wastes. Monitoring and attention. Due to the uneven development of the planting and breeding industry in various regions of China, there is no quantitative data and unified measurement standards for waste consumption, utilization methods, proportions, and specific applications. Although the Ministry of Agriculture issued the "Technical Guidelines for the Calculation of the Land Carrying Capacity of Livestock and Poultry Manure" in early 2018, it provides a guideline on the carrying capacity of regional livestock and poultry manure, the supporting land area for manure consumption of large-scale livestock and poultry farms, the supply of manure nutrients, and the unit The measurement methods such as land manure nutrient requirements have been unified, but there are still many types of wastes from different planting and breeding industries in China, and it is difficult to completely cover them. There is still a lack of comprehensive waste utilization models and nutrient management techniques for returning waste to fields based on regional characteristics and economic development conditions. Influence, the lack of a recycling technology model with obvious technical advantages between planting and aquaculture leads to insufficient integration of planting and breeding, which not only limits the pace of Fertilizer utilization of planting and breeding waste resources but also limits the development of ecological circular agriculture.
The harmless treatment technology of waste is an important factor affecting the safe utilization of Fertilizer. However, at present, China's waste innocuous treatment and Fertilizer technology are backward, the original fine traditional composting technology and biogas technology have not developed much, and there are few core technologies with independent intellectual property rights, and there is a lack of technologies with broad applicability and promotion value. and equipment, less investment in the research and development of Fertilizer equipment, poor technological innovation, some good technologies cannot be applied and promoted in the process of industrialization transformation, resulting in the repetition of waste recycling at a low level and the development of Slow and unable to meet the needs of social production; in addition, the problems of heavy chemical Fertilizers and light organic Fertilizers in agricultural production are prominent, the combination of planting and breeding is not close, and breeding and planting are separated, resulting in backward waste recycling technology; manure, biogas Fertilizer and other Fertilizers Incomplete production technical standards, lack of technologies such as how to reduce nutrient loss during processing and storage, inadequate mechanized equipment in the application process, insufficient innovation in Fertilizer application equipment, lack of availability of organic Fertilizers or combined application with chemical Fertilizers based on nitrogen, phosphorus and potassium nutrients These factors seriously restrict the innovation and development of waste Fertilizer technology.
With the widespread use of Cu, Zn, As and other trace elements as feed additives in large-scale livestock and poultry breeding, the risk of excessive heavy metals and antibiotics in commercial organic Fertilizers produced with livestock and poultry manure as the main raw materials is serious. These harmful substances have the risk of being absorbed by crops and entering the food chain and accumulating in the agricultural environment to contaminate agricultural products and the environment. According to statistics, about 150,000-180,000 tons of trace element additives are used in China every year, and about 100,000 tons are not used by animals and enter the environment with livestock and poultry manure. At present, due to the unsatisfactory quality of organic Fertilizer products, the inability to keep up with agrochemical services, the inadequacy of supervision, etc., the phenomenon of shoddy shoddy organic Fertilizer market occurs from time to time, which seriously restricts the development of the organic Fertilizer market. To increase the price advantage, some enterprises do not hesitate to reduce production costs, which greatly reduces the effect of organic Fertilizers on soil and crops, and even reduces the psychological expectations of farmers for the use of organic Fertilizers.
The above is the relevant content about the problems faced by the utilization of Fertilizers in China's planting and breeding industry. If you are interested in Fertilizer, you can contact us.
