With the adjustment of agricultural policies and the acceleration of the iteration speed of fertilizer research and development technology, China's fertilizer industry has changed from traditional fertilizers to complex, functional, scientific and technological, and ecological directions. In order to grasp the direction of industrial development and promote the exchange and integration of industry, education and research, more than 500 people from various agricultural authorities, agricultural scientific research colleges, outstanding enterprises in the agricultural material industry and agricultural materials industry attended the forum from September 13-14, sponsored by the National New Fertilizer Cooperation Group.
Zhang Xiaobiao, Secretary General of the National New Fertilizer Cooperation Group
Zhang Xiaobiao, secretary general of the National New Fertilizer Cooperation Group, pointed out that with the promotion of relevant policies such as the Implementation Opinions of the Ministry of Agriculture on Promoting the Structural Reform of the Agricultural Supply Side and the substantial increase in the area of water-saving irrigation in agriculture, China's liquid fertilizer industry has entered a period of rapid development. With the adjustment of policies and changes in market demand, fertilizer products are also constantly upgrading. The special components of marine living resources are to regulate plant growth and activate soil. The three major types of marine living resources such as seaweed, chitin and low-value fish are renewable resources that can be used for fertilizer development and are the focus of new fertilizer product development.
Xin Jingshu, chief expert of the National Agricultural Technology Extension Service Center of the Ministry of Agriculture and Rural Affairs, stressed that in recent years, new fertilizer products, new machinery and tools, and new ways of fertilization have been integrated and developed, and the application area of various new fertilizers has reached 300 million mu. Refining the basic work of soil testing and formula fertilization, developing and producing demonstrations and promoting high-efficiency new fertilizer products, highlighting the "three new integration" to promote the transformation of fertilization methods, promoting the efficient use of organic fertilizer resources to scientifically and rationally replace chemical fertilizers, and promoting chemical fertilizer quota standards have become the focus of China's agricultural green development.
Li Pengcheng, a researcher at the Institute of Oceanography of the Chinese Academy of Sciences, said that chitin is present in the carapace of crustacean shrimp and crab, the carapace of insects, fungal cell walls and plant cell walls, and is a very rich polysaccharide resource; chitosan is obtained by chitin by deacetyl action, and is the only natural alkaline biopolysaccharide with positive charge in nature; chitosan oligosaccharide is a low molecular weight product of chitosan degradation. It is non-toxic to humans and animals, has good biocompatibility, is biodegradable, and has a wide range of activities. Chitosan oligosaccharides have excellent performance in promoting plant growth, inducing plant salt resistance, and improving plant resistance to heavy metals.
Li Yiqiang, chief of the innovation team for the conservation and utilization of biological resources in the beach of the Chinese Academy of Agricultural Sciences, introduced that the yield of seaweed and its waste is huge, in traditional agriculture, simple process fermentation of seaweed extract has been used as organic fertilizer; and in recent years, studies have found that seaweed extract can also exert the effect of biostimulants and improve the stress resistance of plants. Tending to develop from mixtures to single substances, whether it is microalgae or macroalgae, the preparation of biostimulants from the abundant seaweed polysaccharide resources in seaweed has good application prospects.
The participants said that the forum closely followed the pulse of the policy and the market, solved the pain points and difficult problems of many fertilizer enterprises in product research and development, and also built a broad exchange and cooperation platform between the majority of fertilizer enterprises and R & D institutions, and made great contributions to promoting the upgrading of liquid fertilizer products, industrial acceleration and healthy transformation in China.
