棉麦两熟是我省棉区的一种主要栽培制度。在棉、麦套种的条件下,采用化学除草,保持麦田洁净无草,为棉花播种及苗期生长创造良好环境条件,对棉麦增产有重大意义。 1973年早春,我们选用几种最常用的化学除草剂在小麦田进行比较试验,以评选防除效果较好的除草剂,并找出其适当的施药时间和施药方法,为大面积使用除草剂提供技术资料。 Cotton and wheat two crops is a province of cotton cultivation system. In cotton, wheat intercropping conditions, the use of chemical weeding, wheat field to keep clean grass, cotton planting and seedling growth to create good environmental conditions, the cotton yield is of great significance. In the early spring of 1973, we selected several kinds of the most commonly used chemical herbicides in the wheat field to compare and test the herbicides with better control effects and find out the appropriate application time and application method, Agent to provide technical information.
