Anhui Provincial Department of Science and Technology, Development and Reform Commission, Environmental Protection Bureau, Hefei Science and Technology Bureau, Chinese Academy of Sciences Biology Bureau, Capital Resources Development Bureau and other relevant leaders, as well as more than one hundred experts and technicians from the front line of scientific research have recently participated in the “lost-control†chemical fertilizer test. Demonstration summary and academic seminar.
According to experts, the "fixed control of chemical fertilizers" technology developed by the Chinese Academy of Sciences Key Laboratory of Ion Beam Bioengineering after many years of research and development is based on the use of natural materials - macromolecular nanomaterials derived from Anhui Province's abundant attapulgite clays. And biological modification, the use of its inherent adsorption properties and colloidal properties, and synergistic effects of compound materials to form a huge network, the network catch fertilizer fertilizer, so as to reduce nutrient loss, improve fertilizer utilization, reduce environmental pollution purposes. The technology has been transferred to Anhui Yuanyuan Biotechnology Company in the early stage and is currently in industrialization.
The "lost-control" chemical fertilizer produced by the use of loss control technology has undergone large-scale production experiments in the catchment area of ​​Chaohu Lake in the past two years and has achieved good results. Compared with traditional chemical fertilizers, the "available" nitrogen fertilizer utilization rate increased by more than 20%; all test sites increased production, with an average increase of 14.2%.
“Controlled Loss†of Chemical Fertilizers During the heavy rain tests in Hefei area, the combined loss of nitrogen, phosphorus, and other runoff from slope lands decreased by 47.8% compared to ordinary chemical fertilizers, and the soil nitrogen inventory increased from 60% to 90%.
According to experts, “controlling lost†fertilizer production is simple, low-cost, easy to use, water-retaining, long-term, high-yield, insect-resistant and lodging-resistant. It is widely used in large-scale crops, middle- and high-end economic crops, and a variety of flowers, seedlings, and green grasslands. Golf course and so on. Experts pointed out that “controlling lost†fertilizers only need to apply base fertilizer once a season, which greatly saves labor costs and reduces the burden on peasants.
For a long time, the problem of low utilization rate and serious loss of chemical fertilizers in China has not only caused huge losses, but also brought about long-standing blue-green algal blooms, food contamination, and threats to human and animal safety. The loss control technology for nitrogen fertilizers developed by the Key Laboratory of Ion Beam Bioengineering of the Chinese Academy of Sciences in Chaohu waters has performed well after two years of large-scale production experiments. Compared with traditional chemical fertilizers, the "available" nitrogen fertilizer utilization rate increased by more than 20%; the average increase in all test sites was 14.2%.
