納米農藥技術助力寧夏農業綠色高質量發展
2020年8月3日，沐鸣2蔡冬清研究員赴寧夏參加寧夏重點研發計劃項目“納米肥藥研發與寧夏優勢特色作物肥藥減施增效關鍵技術集成示範（項目號：2018BBF02021）”現場驗收會。在本項目中，沐鸣2娱乐與中科院合肥物質科學研究院聯合承擔了課題4“新型納米控失農藥創製及病蟲害綠色防控技術研究與示範”的研究任務。來自寧夏科技廳🧑🚀、中科院微生物研究所⏏️、西北農林科技大學🧑🏽🚀、甘肅農業大學、寧夏大學🌅👩🏫、寧夏農科院🚵♀️、寧夏農業技術推廣總站等的三十余位專家參加了本次現場觀摩和驗收會⟹，並對該技術給予高度評價。
本課題針對寧夏優勢特色作物存在的病蟲害高發難防、農藥高施低效關鍵問題，研發升級了寧夏專用農藥納米控失劑，並在枸杞、蔬菜上累計示範606畝🈵，可在穩效條件下減少農藥用量20%以上🛝，提高農藥利用率15%，為寧夏農業高質量發展和農業面源汙染削減提供有效科技支撐，該技術深受當地農戶和種植大戶的青睞。
註🚑🚻：針對農藥流失引發的面源汙染問題🏟，沐鸣2娱乐與中科院合肥物質科學研究院聯合👉🏿，利用輻照改性納米黏土研發出農藥控失劑，該控失劑相當於為農藥液滴安裝了微型“爪子”，提高農藥在作物葉面上的附著率，促進農藥減量增效。圍繞該技術，孵化成立青島中科禾輝生物技術有限公司實現其產業化🧜🏼，產品已進入德國巴斯夫等大型公司農藥配方，在我國和孟加拉國等地累計推廣5000余萬畝👈🏿，可降低農藥用量20%，創造直接經濟效益5億余元🔢，有效緩解了農藥引起的農業面源汙染🔏🐗。該技術榮獲2018年度寧夏科技進步三等獎及2018年度“孟加拉國農業獎”（國家級）。

Ningxia Agriculture with Green and High-Quality Development Booms through Nano-Pesticide Technology
On August 3, 2020, Professor Dongqing Cai from the College of Environmental Science and Engineering in Donghua University visited Ningxia Province to participate in the on-site acceptance meeting of Key Research and Development Project of Ningxia. The program is Nano-fertilizer research and development and key technology of integration and demonstration on synergistic reduction fertilizer and pesticide application on Ningxia's dominant crops (2018BBF02021). In this project, Donghua University and Hefei Institute of Physical Science of Chinese Academy of Sciences jointly undertook the research task of Topic 4 Creation of new nano-lost controlling pesticides and research and demonstration of green prevention and control technology on pests. More than 30 experts from Department of Science and Technology of Ningxia Province, Institute of Microbiology of Chinese Academy of Sciences, Northwest Agricultural and Forestry University, Gansu Agricultural University, Ningxia University, Ningxia Academy of Agricultural Sciences, Ningxia Agricultural Technology Extension Station, etc. participated in this on-site observation and acceptance meeting and gave high praise to this technology.
The program focused on the key problems of Ningxia's dominant crops with high incidence and hard control of diseases and insects and high dosage but low efficiency of pesticide application. This project has developed and upgraded the Ningxia special pesticide nano-lost controlling agentia, which has been used on a total area of 0.404 km2 on wolfberry and vegetables. As a result, the application of agentia reduced pesticide consumption by more than 20% and increased pesticide utilization rate by 15% under stable conditions, which can provide effective scientific and technological support for high-quality agricultural development and reduction of agricultural non-point source pollution in Ningxia. This technology is favored by local farmers and large growers.
Note: In order to solve the problem of non-point source pollution caused by the loss of pesticides, Donghua University and Hefei Institute of Physical Science of Chinese Academy of Sciences have jointly developed a pesticide loss control agent by using radiation-modified nanoclay. This loss control agent simulates the miniclaws assembled on pesticide droplets, which improve the adhesion rate of pesticides on crop leaves and promote pesticide reduction and efficiency. Based on this technology, Qingdao Zhongke Hehui Biotechnology Co., Ltd. was established to implement its industrialization. The products have been chosen into the pesticide formulations of large companies such as BASF in Germany. Furthermore, they have been extensively applied in more than 33333 km2 in China and Bangladesh, which can reduce pesticides dosage by 20 %, create direct economic benefits of more than 71.9 million dollars, and effectively alleviate agricultural non-point source pollution caused by pesticides. This technology won the third prize of Ningxia Science and Technology Progress Award in 2018 and the 2018 Bangladesh Agriculture Award (national level).
