直播稻田除草剂飞防技术现状与发展

Status and Development on Aerial Protection Technology of Herbicide in Direct Seeding Rice Fields

随着无人机技术的发展,植保无人机在农业上的应用也越来越广泛。直播稻田杂草发生量大、草相复杂,与水稻争夺资源,是影响水稻产量和品质的重要因素之一,植保无人机用于直播稻田除草具有效率高、成本低、用工少等优点。本文基于直播稻田除草剂飞防技术使用现状,分析直播稻田除草剂土壤处理剂与茎叶处理剂飞防技术的主要制约因素,从植保无人机装备、专用除草剂剂型和助剂以及相应栽培管理措施等方面探讨直播稻田除草剂飞防技术的发展方向,以期为无人机在直播稻田杂草防除中的应用提供参考。

As the development of technology,the application of plant protection unmanned aerial vehicles(UAV)in agriculture is more and more widespread.In direct seeding rice fields,weed with the large number of occurrence and complex community competed with rice for resources,which is one of the important factors reducing rice yield and quality.There are the advantages of high efficiency,low cost and small labor demand when plant protection UAV is used to control weed in direct seeding rice fields.Based on the application status of plant protection UAV weeding,it was analysised in the main restricting factors of aerial protection technology of pre-emergence herbicides and post-emergence herbicides in direct seeding rice fields.The trends of aerial protection technology application of plant protection UAV in direct seeding rice fields was discussed in the UAV equipment,special herbicide formulations and adjuvants,the corresponding cultivation measure,etc..It was the aim to provide reference for the application of UAV weeding in direct seeding rice fields.
