In May 16th, the seminar on nitrogen fertilizer efficiency was held in Henan, Xinxiang. From the Chinese Academy of Sciences, Academy of Agricultural Sciences, Agricultural University, China Huazhongnongda, Southern China Agricultural University and other units of the 20 big coffee industry meeting published -- the efficiency of nitrogen fertilizer efficiency in high perspicacity carrier, trace elements, loss control technology, the stability of technology will help the comprehensive modification, synergistic fertilizer. The meeting held that the efficiency of urea will gradually occupy the mainstream market. Academician of Chinese Academy of Sciences, Nanjing Institute of soil Zhu Zhaoliang will be highly concerned about nitrogen fertilizer efficiency.
Zhu Zhaoliang said that the implementation of chemical fertilizer "zero growth" nitrogen fertilizer bear the brunt. The practice shows that the performance and function of nitrogen fertilizer will be greatly promoted by adding biological activity increasing carrier and fertilizing precision. China plant nutrition and fertilizer society director, Changbai road believes that urea and trace elements, as well as humic acid, alginic acid and other synergist together, synergistic effect is good.
This seminar is equivalent to the efficiency of nitrogen fertilizer of Huashan mountain, fertilizer Chinese new fertilizer technology led value-added academy chief scientist researcher Zhao Bingqiang is leading the trend of the traditional value-added modified urea. He said at the meeting, the compatibility of fulvic acid, zinc alginate, cereal and biological activity of synergistic carrier with traditional fertilizer science, realize the comprehensive control of fertilizer, crop and soil ", greatly improve the utilization rate of fertilizer. Ten years later, the value-added of fertilizers will form a new normal and new format in china. Today, white urea is the norm, and after ten years, value-added black urea may be the new normal." For nitrogen fertilizer efficiency, Zhao Bingqiang clear thinking.
According to reports, the Chinese Academy of Sciences Hefei Institute of material through the loss control technology is a good solution to the traditional urea fertilizer, the loss of the short, the technical director Wu Yuejin researcher said that the loss control urea of high efficiency, simple production process, not only the stability, and the functional and biological activity is an important synergistic nitrogen fertilizer product.
Huazhong Agricultural University trace element research center Professor Wu Lishu said, the middle and trace elements in nitrogen fertilizer efficiency effect is remarkable. At the same time, the Chinese Academy of Sciences Shenyang Institute of ecology researcher Lu Zongyun introduced by adding urease inhibitor, nitrification inhibitor on traditional urea modified synergistic inorganic coated slow release technology, Zhengzhou University professor Wang Haobin introduced are considered to be effective measures of urea efficiency.
Experts believe that urea, ammonium nitrate solution (UAN) as the basis for the formation of liquid compound fertilizer is also an important way to increase nitrogen fertilizer. According to South China Agricultural University professor Zhang Chenglin introduced, the United States, France, Britain and other countries use liquid fertilizer more. With the acceleration of land transfer, liquid fertilizer will usher in a larger market in china. Wang Xu, a researcher at the Chinese Academy of Agricultural Sciences, also believes that UAN is important for developing liquid fertilizer.
The chief expert of the National Agricultural Technology Center of the Ministry of agriculture, said Gao, a researcher at the National Agricultural Technology Center, will develop effective nitrogen fertilizer from the aspects of reducing leaching loss, quick effect, long effect, cooperating with other elements (additives) and raising the utilization ratio. As for nitrogen fertilizer efficiency, Professor Siu Siu Tang, a professor of agriculture in China, suggested that it is a feasible approach to improve the performance of traditional nitrogen fertilizer through proper cooperation with other nutrients such as middle and trace elements.
