我国是农业大国，人口众多，土地相对较少。通过不断增加施肥量，作物产量得到提高。同时 过度施肥，造成土壤严重板结，地表、地下水受到不同程度的污染。通过相关数据显示肥料用量愈大的地区（蔬菜种植），污染愈严重，究其原因主要是肥料利用率太低。磷、钾不及使用量一半，氮利用率甚至达不到30%，经济效益和生态效益 资源损失巨大。如何提高肥料的利用率，降低污染，让养分释放与作物养分吸收同步，成为新型肥料产业的发展方向。
1,The Present applies fertilizers situation
Our country is the large agricultural nation, the large population, land relativr are less. Through unceasingly increases fertilizers,the crops output obtains the enhancement . Simultameously excessively appliesfertilizer,creats the soil serious to harden ,the surface,the ground water receive the varying degree the pollution ,.Through the relevant data shows fertilizer used more area (vegetable planting), pollution is serious, investigates itsreason mainly is the fertilizer utilization ratio is too low. Phosphorus, potassium, nitrogen utilization as usage half reach 30%, even economic and ecological resources lost millions. How to improve the fertilizer utilization ratio, reduce pollution, let nutrient release and crop nutrient uptake synchronization, a new fertilizer industry development direction.
2, controls releases the fertilizer mechanism
Through to spread the membrane material the modification and spurts spreads the seal,the conditioner,the fertilizer the realization with slows release controls releases , changed with the using fertikiser structure ,make it possible for agricultural promotional use .
The employment controls releases the fertilizer could improve the ecological environment, reduces the groundwater and table water pollution; Save a great deal of coal, electricity and natural Gas and other non-renewable resources; Nutrient-efficiency increases 30 ~ 50%, control sustained-release fertilizer than the surueyed reduce 1/3-1/2. For example, with nitrogen element in 30 million tons annually after surueyed controlled-release dosage 15 million tons, according to the present market value calculation, can save money more than 200 billion yuan, if counting on phosphorus, potassium resources for the country, will save tremendous energy and funds; And application of convenient, can fill sulfur, increasing production.
Our company has been committed to the compound, fertilizer material production equipment research and development and production, and domestic well-known relevant institutes cooperation controlled-release fertilizes the continuous and large-scale production research, in 2003 by the Chinese academy of success, trial-produce group identification, have reached the international advanced level.
