In a sense, fertiliser feeds China! Without fertilizer there is no food security in our country! Professor Zhaobingjiang, a new fertilizer scientist at the Chinese Academy of Agricultural Sciences, used a very refined and very meaningful sentence as the opening of his academic report. July 16, "Hao Hua Chun Chemical Group and the Chinese Academy of Agricultural Sciences strategic cooperation signing ceremony and Chun-zinc-humic acid" zinc "farmers" green production "project Initiation Ceremony" in Zhumadian, Henan successfully held, launched China's first zinc-humic acid-efficient compound fertilizer. As a developer of zinc-humic acid, through the future development of fertilizers and the analysis of the value-added fertilizers and the effect and efficiency of zinc-humic acid, the present and future trends of zinc-humic acid are reported with detailed data.
It is understood that China's fertilizer industry exists, such as overcapacity, low level of resource security, the utilization of organic fertilizer resources is not high, variety types although rich and diverse, but the structure is unreasonable, the overall level of industrial technology is not high, energy saving and emission reduction pressure, the modernization of fertilization equipment is very low, high yield fertilization brought about by environmental pressure, Fertilizer related policies are not perfect and so on a series of problems. The amount of fertilizer used in China will also be facing the peak of the state, which will be faced with the development of China's fertilizer industry, but also to walk at the crossroads, and the inflection point is coming.
"Quality substitution quantity is the future development path of China's fertilizer industry!" Professor Zhaobingjiang said in his report that the focus of future fertilizer research should be on how to improve efficiency and utilization, rather than continue to significantly increase fertilization levels. Renew the idea, break the tradition, strive for in the next 20 years, China's fertilizer industry to implement quality alternative quantity development strategy, the amount of fertilizer to control at about 55 million tons, without increasing the amount of fertilizer or a small amount of increase in the premise of increasing efficiency, to ensure that China's food security.
The Ministry of Agriculture Statistical Survey, the national circulation of arable land 340 million mu, accounted for 26% of the national farmers contracted farmland, the average size of 200 mu of family farm 870,000, an average area of 50 acres of large growers 2.87 million. Farmers Professional cooperatives 980,000, leading enterprises 120,000, for the farmers to serve the business organization of 1.15 million. These changes of land circulation and large-scale operation as well as the mode of production of irrigation system are changed by the agricultural production system. There is a shortage of phosphorus and potassium resources and the establishment of regulations in the fertilizer industry will be the main driving factors affecting the future development of fertilizer industry.
Zhaobingjiang mentioned in the report. The negative effect caused by the unreasonable application of fertilizers is from quantitative change to qualitative transformation. The correction of soil ecological balance: excessive reliance on chemical fertilizer, pursuing high yield, flourishing continuous cropping, and large amount of medication lead to problems of soil ecological balance and nutrient balance. The development of new varieties such as biological fertilizers, functional fertilizers, correcting continuous cropping obstacles, improving soil ecological balance and reducing pests and diseases. Remediation of farmland pollution: functional recovery of contaminated degraded soils, and soil conditioners play a role. such as cadmium rice: the development of cadmium-rice pollution control fertilizers, production of functional fertilizers. The lack of correction of trace elements: the development of highly active liquid fertilizers, the promotion of growth, the correction of trace elements, improve quality, improve production. Mainly fruit trees, vegetables, cash crops and so on. Agricultural waste pollution environment: the development of organic fertilizer, the realization of nutrient resources recycling.
The report also pointed out that China's fertilizer industry development direction will be divided into three parts, one is water-soluble fertilizers. The second is to increase the efficiency of fertilizer-quality enhancement. followed by soil conditioning products. Improving fertilizer utilization rate is the main way to increase the efficiency of chemical fertilizer. The main technical features of the value-added fertilizers are as follows: the efficiency of the synergist is high, and the added amount is between 0.3 and 3. Nutrient content is not affected, such as the value of urea nitrogen content is not less than 46%; The increase efficiency is obvious, the added Synergist has the normal detectable property, the synergist is the natural substance of plant source and its extracts, it is harmless to environment, crops and human body. , simple process and low cost.
"Zinc-humic acid products after 17 provinces, 12 crops, 56 trials, through the network effect of the test proved that the average crop yield 9.6%, nitrogen utilization rate increased by 7.9%. Zhaobingjiang in the report, the efficiency mechanism of zinc-humic fertilizers can be summed up in the following 3 areas: one is to promote crop root growth, improve root vigor, enhance crop nutrient uptake; second, improve the stability of nitrogen fertilizer, change the release, transformation and moving process of fertilizer in soil, reduce ammonia volatilization loss and nitrate leaching. The third is to change the structure of fertilizers, delaying the release and conversion rate of fertilizers.
The report mentions that zinc-humic compound fertilizer has the function of bio-stimulation: improve root vigor and promote crop nutrient uptake; n Slow-release function: significantly reduce ammonia volatilization loss, improve the utilization rate of nitrogen; PK anti-fixed function: Improve soil effective phosphorus and potassium content, to facilitate crop uptake, and replenish and activate soil calcium, magnesium, zinc, boron, Manganese and other trace elements, regulate the balance of organic carbon nutrition, promote crop yield, improve product quality and other five major functions. Can significantly reduce the loss of ammonia volatilization and significantly reduce the retention of phosphate.
"In Shandong Jiaxiang, Yucheng, Linyi, Leling carry out 100 mu of the whole system of production per mu ton of half grain super high yield." Shandong Yucheng Create 750 kg/mu high. Zhaobingjiang the high yield and efficiency of new type fertilizers such as zinc-humic acid fertilizer were analyzed through detailed test data. Pilot demonstration User Zhang Cenyue from Linyi, Texas, has set the target per mu of wheat 1000 kg/mu.
The report also proposes future development plans for value-added fertilizers. Zhaobingjiang said that the next 5 years to develop 10 million tons of value-added urea (agricultural urea 25%), 10 years 20 million tons (agricultural urea 50%); The next 5 years of development 10 million tons of value-added compound fertilizer (the amount of compound fertilizer product 25%), 10 tons in 20 million years (50%) In the next 5 years, the development of 5 million tons of value-added two ammonium (second ammonium commodity volume 35%), 10 tons in 10 million years (70%). Zhaobingjiang stressed that the annual development of 20 million tons of value-added urea, 20 million tons of value-added fertilizer, 10 million tons of value-added ammonium phosphate products, so that China's ordinary chemical fertilizer more than 30% to achieve value-added modification, promote the performance of traditional chemical fertilizer products upgrade, the annual area of 1 billion acres, increase grain 20 billion Reduce the loss of fertilizer, protect the environment.
It is reported that December 5, 2012, "chemical fertilizer value-Added Industry technology Innovation Alliance" was established in Beijing. The establishment of the Alliance aims to promote the comprehensive value-added modification of Chinese traditional fertilizers and the development of fertilizer modernization.
The composition and synergism mechanism of alginate synergist, alginate urea, glutamine synergist and cereal urea were also discussed in the report.
