我国是一个农药使用大国,每年防治面积达60多亿亩次,防治病虫需使用农药30多万吨(折百计),这些农药主要依靠药械进行喷洒。植保药械功效的高低和施药技术水平直接关系到重大病虫害防控能力和效率,关系到农药的利用率和生产成本,关系到农药残留和环境保护。目前我国植保药械发展的现状如何?存在哪些问题?应从哪些方面着力改进?近日,记者就相关问题采访了中国农业大学药械与施药技术研究中心主任何雄奎教授。
China is a large country that uses pesticides. Its annual prevention and control area reaches more than 6 billion mu. Pesticides should be used in the prevention and control of pests and diseases at more than 300,000 tons (hundreds of dollars). These pesticides are mainly sprayed by medicine machines. The effectiveness of plant protection medicinal materials and the level of pesticide application are directly related to the prevention and control of major diseases and insect pests and their efficiency. They are related to the utilization rate and production costs of pesticides, and are related to pesticide residues and environmental protection. At present, what is the status quo of the development of China’s plant protection medicinal materials? What problems exist? Which aspects should be improved? Recently, the reporter interviewed Professor He Xinkui, director of the Research Center of Pharmacy and Pharmacy and Pharmacy at China Agricultural University.
