摘要
针对当前新疆三大产棉区机采棉不同生育期杂草发生种类及危害特点,在对杂草防控技术措施调查和试验研究的基础上,结合生产实际,按照综合防控、治早治小、减量增效的原则,优化集成机采棉生产各环节杂草防除技术,制订了规范化防控机采棉田杂草的技术规程,包括播种期、苗蕾期、花铃期、吐絮期以及棉花收获后各阶段杂草防除技术措施的选择、应用技术要点、注意事项等,以期为棉田草害科学防控、机采棉安全生产提供技术支撑。
Based on the occurrence and negative impact of weeds at different growth stages of machine-harvested cotton in three major cotton-producing areas of Xinjiang,a technical regulation for standardized weed control was formulated considering the investigation and experimental research on weed management.It combines the production practice and adopts the principles of comprehensive prevention and control at early and young stages,and the reduction of the dosage and improvement of the efficiency of herbicides.The technical regulation includes the selection of weed control tactics,key points of application technology and precautions at sowing,seeding and bud stage,flowering and boll stage,boll opening stage and after cotton harvest.It provides technical support for scientific prevention and selective control of weeds in machine-harvested cotton fields.
