　　【农机网 政策与标准】近年来，为加快补齐水稻机械化生产育苗、插秧短板，提升水稻生产综合机械化水平和提高水稻单产水平，贵州省积极推广水稻全程机械化技术，并相继制定实施了多项相关技术地方标准。
 
　　其中，《DB52/T 1246.5-2017 贵州水稻机插秧全程机械化 第5部分 植保》由贵州省农业委员会提出并归口，贵州省山地农业机械研究所、贵州省农业技术推广总站、贵州省农业机械推广总站起草，于2017年12月8日由贵州省市场监督管理局批准发布，于2018年5月8日正式实施。
 

 

　　本标准适用于地势较平坦的稻区水稻植保中药剂防治机械化作业，规定了水稻植保机械化的术语和定义、作业条件、作业要求、作业安全要求。
 
　　作业条件——
 
　　确定植保方案：了解水稻不同生长期病虫草害发生特点，选择合适的农药品种对症下药，并按标准用药量用药。根据水稻病虫草害特点和药物特性及用量，确定喷洒作业方式。防治时期和用药量应符合 DB52/T 898 的要求。
 
　　机具准备：
 
　　新机具安装要按说明书上的图示顺序连接，检查各部分零件是否齐全，各接头垫圈是否完整无损，然后连接各部件。旧机具检查各部件是否完好，使用多年的药液桶应查看药桶的腐蚀情况，损坏部件要及时更换。
 
　　检查发动机各部分零件是否齐全，安装是否正确、牢固可靠。
 
　　仔细检查药械开关、接头、喷头等处螺丝是否拧紧，药桶有无渗漏。
 
　　喷雾机械一般应先加清水试喷，察看各连接处是否漏气漏水，若有漏气漏水现象，需要重新安装，直到调试正常为止。加水盖上的气孔应畅通，防止药液桶内形成真空。
 
　　配制药液并将药液装入箱内，药液不得超过药液箱的安全水位线。
 
　　配制药液应严格按照农药使用说明进行。
 
　　作业要求：
 
　　作业人员要注意安全防护，防护要求按照 6.2 执行。喷洒，覆盖均匀，无漏喷、重喷现象，覆盖密度适中；喷药时应注意风向，尽量与自然风向一致，不允许逆风喷药；使用手动或机动喷雾器喷药时应隔行喷，不能左右两边同时喷。喷管口对作物要有一定角度，不能对着植物，角度大小要视自然风速大小来定，其原则是风速大时，角度要小，风速小时，角度要大；雾化性能良好，雾滴直径大小适宜，穿透、附着性能好。田间施药应在风力较小时进行，高温季节喷撒农药最好在早、晚进行；雾量分布均匀，
 
　　漂移少， 药剂能很好地粘附在植物茎叶上。作业中发现机械运转不正常或其它故障，应立即停机检查、排除，正常后继续工作。停止喷药时，要先关闭输液开关，然后关机。作业结束后要及时清洗药械，装过农药的空箱、瓶、袋要集中处理。
