小麦生长中后期是增粒数、争粒重、夺高产的关键期,同时也是多种病虫集中为害造成产量损失的高危期。有效控制小麦中后期病虫为害,最大限度地减少病虫灾害和干热风带来的损失,对夺取小麦高产有着十分重要的意义。自2010年以来,为保障小麦生产安全,河北省连续实施“一喷三防”物化补贴政策,全省农业部门和植保机构上下联动、协同作
In the middle and late stages of wheat growth, it is a critical period for increasing grain number, fighting for grain weight and winning high yield, and is also a high-risk period for yield loss caused by a large number of pests and diseases. Effective control of pests and diseases in the latter part of wheat, to minimize the losses caused by pests and diseases and dry hot wind, is of great significance to capture high-yield wheat. Since 2010, in order to ensure the safety of wheat production, Hebei Province has continuously implemented the materialization and subsidization policy of “one spray and three preventions”, and the agricultural departments of the province and the plant protection agencies have been linked up and down and collaborated
