In the past, farmers needed to apply fertilizer four or five times in the first season. In the future, this practice may become history. A kind of fertilizer that “dresses in†clothes was successfully developed and put into small-batch production by Yizheng Duoke Water Chemicals Co., Ltd., a private technology company in Jiangsu Province. Crops using this fertilizer need only be fertilized once a season. Recently, the scientific and technological achievements have been incorporated into the “Twelfth Five-Year†agricultural innovation project stockpile by the country. The industrialized production base of this new type of fertilizer is being accelerated in the construction of the Yizheng Development Zone. It is expected that Yangzhou farmers will be able to use this soon. Kind of magical fertilizer. Entering Yizheng Duoke Water Chemicals Co., Ltd., there are rows of storage tanks and various interconnected pipes in the workshop. "This is the controlled-release fertilizer!" Song Shengji, the company's general manager, pointed to a gray round granule in a large container. He said that the scientific name for this product is polymer coated controlled-release fertilizer, which is simply a kind of chemical fertilizer. Clothes, the slow release of fertilizer nutrients, "flowers with this fertilizer, do not apply fertilizer for three or four months." Song Shengji took two transparent glass cups with half a glass of water, and put equally divided granular fertilizers. One was controlled release fertilizer and the other was ordinary fertilizer. After 5 minutes passed, we saw that the glass filled with common fertilizer was cloudy and the fertilizer particles became smaller due to melting, and there was no change in the cup placed inside the controlled-release fertilizer. “Normal fertilizers released nutrients quickly after release, and are easily lost with rainwater, and they do not form a lasting supply of crops. Therefore, crop farmers need to fertilize four or five times in the first season. However, the use of controlled-release fertilizers for one-season crops can be applied once. Provide long-term and balanced nutrients for crops to meet the growing needs of the entire growth period.†Song Shengji said. In 2010, the controlled-release fertilizer project won the first National Innovation Award for Innovation in Agriculture and was selected as the national “Twelfth Five-Year†agricultural reserve project library. "Doctor" also from a traditional building paint production enterprises, to achieve a brilliant turn to the provincial high-tech enterprises. According to Song Shengji, "Duokut" could only produce acrylic emulsions for buildings. The annual output value was about 10 million yuan for many years, and the companies were doing very hard work. By chance, "Doctor" got to know the Nanjing Institute of Soil Science of the Chinese Academy of Sciences. With the technical support of the Chinese Academy of Sciences, he began to boldly innovate and transform. Using the original acrylate emulsion as the main raw material, under the guidance of the experts of the Chinese Academy of Sciences, the process formulation was improved. After more than one year of product testing, the acrylate emulsion made the "clothing" of the fertilizer, and the controlled release fertilizer project was successful. Into small batch production, product technology is mature and advanced technology in China. At present, the industrial production base with a total investment of 80 million yuan is under intense construction and is expected to be put into operation this year. “The market prospect of controlled release fertilizer is very good, and the application of the product is also very extensive.†Song Shengji said with confidence that at present, the annual amount of inorganic fertilizer used in the country is nearly 100 million tons. If 20% of controlled fertilizer is used, it is hundreds of billions of yuan. Market. "Because of the cost of production, the price of controlled-release fertilizers is relatively high, which affects the promotion and use of controlled-release fertilizers. It is understood that the price of controlled-release fertilizers is three times that of inorganic fertilizers of the same composition, so currently there are only golf courses, flower cultivation, etc. It is used in high-end markets and not used in agriculture. However, in the long run, the "comprehensive cost" of controlled-release fertilizers is actually not high. Song Shengji took a piece of information: At present, due to the large amount of inorganic chemical fertilizers and unscientific use, leading to a large number of nutrient losses, low utilization rate, which also brought about environmental pollution, quality of agricultural products, soil quality deterioration and many other issues. According to scientific analysis, it is conservatively estimated that if the national fertilizer utilization rate is increased by 10 percentage points, the current chemical fertilizer consumption level can save more than 10 billion yuan in chemical costs each year. “Controlled-release fertilizers will be a fundamental liberation of agricultural fertilization technology and will relieve the peasants of a large amount of labor payouts and are not afraid of an agricultural revolution.†Automobile aluminum foil covered sound insulation and heat insulation interior trim series Sound Absorbing Material,Building Sound-Absorbing Cotton Material,Heat Insulation For Interior Decoration,Light Weigh Cotton Sound Absorbing Yidebao Technology Development Co.,Ltd. , https://www.zgyidebao.com
