China held in Beijing, "two sessions" involving scientific research and agricultural extension agricultural representatives and members from the soil, fertilizer use efficiency, agricultural labor efficiency point of pushing the slow-release fertilizer. They think that the current slow-release fertilizer to promote the difficulty is the high price, the proposed policy to give support to increase the promotion efforts.
Food security in the "two sessions" hot topic, the participants members believe that China is so densely populated, increasing agricultural productivity is imperative. Fertilizer is the material guarantee for the sustainable development of agriculture, food production is the material basis, but in recent years because the excessive use of fertilizers, resulting in energy waste and environmental pollution, there is an important reason for this phenomenon is caused yield reduction of fertilizer use efficiency decline.
National People's Congress of Henan Academy of Agricultural Sciences Research Center of wheat for steel, said Xu, a new type of slow-release fertilizer as a fertilizer, in line with simplified cultivation of agriculture on the need for light. However, there are still in the promotion of application method, not suitable for crop growing season length, dry fertilizer, and limited production cost, the proposed production enterprises to increase R & D efforts, to promote science to use, and the government sector should also increase support for production enterprises in the equipment manufacturing and R & D subsidies, so that the new farmers access to safe and inexpensive fertilizer.
CPPCC member and vice president of Hebei Province, Wang Haibo, forestry science to bring this proposal to "actively promote the development of applications on the slow-release fertilizer." He told reporters that the current annual production and consumption of fertilizer in China accounted for 30% of the world and 35%. But with the substantial increase in fertilizer (especially nitrogen), fertilization effect of diminishing the problem has been very prominent. This not only led to a lot of waste, but also the formation of agricultural non-point source pollution. Therefore, the reform of the traditional form of chemical fertilizers, promote the use of slow release fertilizer, has become promoting agricultural modernization, a major task for sustainable development.
In this regard, the CPPCC National Committee, President of Nanjing Branch of Chinese Academy of Sciences, Soil Science Society of China, chairman of Jian-Min Zhou said that China's agricultural nonpoint source pollution problem is more severe in many areas of the rivers and lakes are subject to pollution, more and more fertilizer place, point source pollution is more serious, this is an indisputable fact. Only from the source to control the release of nutrients, can be effective in governance.
However, the current agricultural production in China is still in extensive stage small farmers operate, the concept of scientific fertilization has not yet reach all farmers, coupled with the increase of migrant peasant workers, reduced agricultural production and labor, more extensive agricultural fertilizer. NPC, Xincheng fertility Zhanfuzhanchang Mongolia Tieying proposed, slow-release fertilizer or fertilizer if one can do to reduce fertilizer, farmers will be very welcome. But the slow-release fertilizer in the price not too high, otherwise farmers will not be accepted.
According to the survey, due to slow-release fertilizer price is relatively high, the current amount of use in field crops is not large, the Chinese Academy of Agricultural Sciences, Institute of Agricultural Resources and Regional Planning Committee, told reporters researcher Huanghong Xiang, China study for the slow-release fertilizer has been 50 years of history, the level of gap between us and the world is not large, the only problem is the slow-release fertilizer price is relatively high, mainly for economic crops, suggested the country should be given some subsidies to play a slow-release fertilizer certain ecological benefits.
