导读：湖北省《DB42/T 1881-2022虾稻共作模式水稻机械化作业技术规程》即将于2022年8月28日开始实施。

　　【农机网 政策与标准】虾稻共作水稻全程机械化生产模式针对虾稻共作水稻种植要求，在兼顾小龙虾养殖效能条件下，可有效提高虾稻生产机械化水平。2022年6月28日，湖北省市场监督管理局批准发布了《DB42/T 1881-2022虾稻共作模式水稻机械化作业技术规程》，即将于2022年8月28日开始实施。


 

　　本标准由湖北省农业农村厅提出并归口管理，由荆州市农业技术推广中心、长江大学、荆州市荆楚富民农机专业合作社联合社起草。
 
　　本标准提出了虾稻共作模式下虾稻种养大田耕整、插秧、植保和收获等环节机械选择要求与机械作业技术要点，规定了各环节机械作业质量。适用于湖北省虾稻共作模式水稻机械化生产。
 
　　大田耕整——
 
　　机具选择：根据水田泥脚深度、田块大小及形状、土壤性能等因素选择耕整机。宜选择功率36 kw以上轻型履带式拖拉机配水田旋耕机作业或履带自走式旋耕机作业，旋耕机作业幅宽≥2.3 m，机具符合JB/T 12673或JB/T 13081的规定。
 
　　作业要点：
 
　　整地前2 d～3 d开始排水，使虾沟水面低于田面10 cm以上。
 
　　整地前按农艺要求施好底肥，底肥以复合肥和有机肥为主。
 
　　田面杂草较少的田块，只旋耕作业一遍。
 
　　田面杂草较多的田块，机械作业两遍。第一遍用带埋草功能的旋耕机将草埋覆在田面下，2 d～ 3 d 后再用旋耕机旋耕第二遍。
 
　　作业质量：
 
　　旋耕层深度12cm-15cm,旋耕层深度合格率≥85%，耕后地表平整度≤3cm.作业后田间无漏耕，无壅泥、壅草现象，泥浆深度5cm-8cm。
 
　　植保——
 
　　防治方式：优先选择物理防治和生物防治方式，化学防治严禁使用菊酯类农药、有机磷类、阿维菌素类及对小龙虾有毒性的农药。
 
　　机具选择：选用能高效、精准施药的植保无人机和喷杆式喷雾机。植保无人飞机应符合NY/T 3213 的要求。喷杆喷雾机应符合GB/T 24667.1 的要求。
 
　　作业要点：作业时间以病虫害测报时间为准，及时进行防控。
 
　　施用的农药符合 DB42/T 1606 和 T/CAMA 05 的规定。
 
　　自走式喷杆喷雾机药箱最大装液量不超过药箱额定容量的 2/3 。
 
　　自走式喷杆喷雾机作业时最外侧喷头离虾沟的距离≥1 m，作业方法和施药符合 NY/T 1876 的规定。
 
　　作业质量：植保无人机作业质量应符合T/CAMA 06-2019的规定。喷杆式喷雾机在额定工作压力下喷雾时，施药液误差率不大于10%，喷雾时雾滴应连续、均匀，雾形完整。
 
　　收获——
 
　　机具选择：选用全喂入履带式谷物联合收割机，发动机功率≥50KW。机具符合JB/T 5117的规定
 
　　作业要点：收获在水稻的蜡熟期或完熟期进行。收获前7d--10d断水晒田，收获时田间无明显泥脚。临近虾沟作业时，低速行驶，谨慎操作，防止机具侧翻。收割机田间作业时不启用秸秆切碎装置，尽量保持直线行驶。田头转弯时，如泥脚较深，加大机具转弯半径。
 
　　作业质量：留茬高度保持在30cm-50cm，秸秆均匀抛撒还田。损失率、破损率、含水率符合NY/T 498-2013中4.2的规定。
