1 植保机械化生产技术现状 经调查江苏植保机械(具)保有量约为800万台,其中老背负式手动喷雾器(空气室外置)有659万台,占82％;新背负式手动喷雾器(空气室内置)有110万台,占14％;机动弥雾机有27万台,占3.4％;机动喷雾机有4.6万台,占0.6％。 以上表明,省内主要农作物病虫草害防治工作中施药技术及施药机具严重老化,绝大多数是70年代技术、80年代产品的陈旧机具。在生产使用中劳动强度大,喷洒均匀性差,功效低下,安全性能差,极
(1) The current status of plant protection mechanization production After investigation, plant protection machinery in Jiangsu Province has an inventory of about 8 million units, of which, there are 659 million old hand-held sprayer (outside air chamber), accounting for 82%; newly knapsack sprayer Built-in) has 1.1 million units, accounting for 14%; motor fog machine has 270,000 units, accounting for 3.4%; mobile sprayer has 46,000 units, accounting for 0.6%. The above shows that the major pesticides and pesticides used in the prevention and control of pests, diseases and weeds in major crops in the province are seriously deteriorating, most of which are old-fashioned implements of the 1970s and the 1980s. In the production of labor-intensive, poor spray uniformity, low efficiency, poor safety performance, very
