Controlled release fertilizer to do with Chinese characteristics

In recent years, the slow release fertilizer into the fertilizer market is unique in the new force. Many enterprises in the fertilizer marketing process, trendy playing the "release" and "release" of the brand, quickly occupied the market of great potential. Overseas, the slow release fertilizer is fertilizer nobility; but in China it is sustained and controlled release fertilizers are a good example on the field application. The development of controlled release fertilizer, beyond the expectations of many people, but also affects many hearts. In the 11th China International Agrochemical & Crop Protection Exhibition (CAC2010) period, experts say, slow release fertilizer to succeed, we must make the Chinese characteristics.
Period of development into the blowout
China Institute of Plant Nutrition and Fertilizer Technical Commission of Bing-Qiang Zhao new fertilizers, slow release fertilizer in our country's development process was carefully combed, he will slow the development of controlled-release fertilizer into three phases, showing a late start, its rapid development, the mainstream technology tracking foreign features. From the early 70s of last century the early 80s, is the exploratory phase; 80 from the last century to 2000, is a slow release fertilizer in the development stage, Zhengzhou University, Beijing Academy of Agriculture and Forestry research institutions represented the beginning of the research and development, and carried out small-scale industrialization; and from 2000 to date, is the rapid development of controlled release fertilizer during the growing consumption.
Bing-Qiang Zhao to the information provided, in 2000 the world consumed one million tons controlled release fertilizers in China only accounts for less than 5%; and to the current world consumption of 1.8 million tons of controlled release fertilizers, there is 1 / 3 about 600,000 tons were consumed in China. According to statistics, the current domestic capacity of slow release fertilizer 2.4 million tons, consumption is still relatively large room for growth.
Technology presents a hundred flowers blossom
It is understood that the present controlled release fertilizer on the market from the technology, price, and so the situation appeared uneven, and even many companies use a variety of controlled release fertilizer technology features of the concept of the phenomenon of speculation. According to information provided by Bing-Qiang Zhao, the current slow release fertilizers can be divided into resin coated, sulfur coated fertilizer package fertilizer, chemical and biological inhibition, urea formaldehyde and other techniques, including controlled release sulfur coated fertilizer accounts for half. It is understood, resin coated, sulfur coated urea and other craft are from Europe and the United States, Japan and other developed countries and regions in attracting relatively high cost; the fertilizer bag fertilizer, chemical and biological suppression of low-cost technology has already been a lot of small and medium enterprises to master, good results and low cost, easy-to large-scale promotion.
According to China Petroleum and Chemical Fertilizer Industry Association of Agricultural Services Office Deputy Secretary-General Xu Xing House briefing, he contacted some companies in Finland adopted a slow release fertilizer technology, at first controlled-release fertilizer per ton increase in the cost of 100 yuan, and now every t only increase the cost of 50 yuan, which indicates that domestic enterprises, technology has matured.
Positioning to have the characteristics
Bing-Qiang Zhao believes that sustained and controlled release fertilizers have a large development, we need to move to field crops is the main battleground. In order to enter field, through the BB form of resin coated fertilizer technology in cost is not dominant, to promote open to a certain degree of difficulty and fertilization more favorable process is simple, inexpensive package type process. Institute of Applied Ecology, Chinese Academy of Sciences, a researcher told reporters that some of the current foreign technology, we already have, and the remaining work is to adapt to different positioning of different fertilizers, high-value crops, the fertilizer can be considered sophisticated technology, and in Daejeon is a low-cost technology on the world fertilizer. En Biotech Shandong Co., Ltd. Zhao Yan that the practice of adding inhibitors of low cost, without capsules coating, is in line with national conditions, he personally optimistic. Data show that in Inner Mongolia potatoes on the use of such controlled release fertilizer, farmers by the consolidated income more than 1000 yuan per mu.
Bing-Qiang Zhao believes that China should establish a system of characteristics controlled release fertilizer, to meet with Chinese characteristics, agricultural production, and the need for policy support. It is understood that China's sustained and controlled release fertilizer industry in the "12 5" period to achieve full industrialization. (Zuimeng)
