At present, how to effectively solve the problem of agricultural pollution, resource conservation, environment-friendly changes in agricultural development has become an urgent need. China's agricultural sector is through the slow release fertilizer in the country to promote ways to protect the agricultural ecological environment.
In recent years, large companies in Shandong Kim as the leading fertilizer company successfully developed a number of slow-release fertilizer, the new fertilizer to control nutrient release rate with time-saving, increase production efficiency, energy saving and environmental protection features, known as the "fertilizer industry a technological revolution." "Eleventh Five-Year" period, China's slow release fertilizer technology into the national science and technology support programs, at present, demonstration and extension range from five provinces in 2008, expanded to 2011 more than 20 provinces.
National Agricultural Technology Extension and Service Center director, said Xia Jingyuan, a long slow release fertilizer fertilizer, nutrient release rate and a certain amount of controllability, and its release pattern of nutrients and crop nutrient uptake basic synchronization, can significantly improve fertilizer use efficiency, reduce the frequency of fertilization with energy conservation, reduce environmental pollution characteristics, is an important direction for future development of fertilizer. From all over the usage point of view, using slow release fertilizer can increase an average of 5-10 percent, up to 30% per acre can increase efficiency 50-100 yuan, a long time up to 200. Also, by reducing the fertilizer will help to improve the agricultural ecological environment. (To quiet)
