为控制豚草的蔓延扩散,通过普查及定点观察的方法,调查豚草在伊犁河谷的发生分布情况,并进行生物学特性观察,分析其发生原因。豚草目前在伊犁河谷主要分布在新源县部分乡镇的路边。玉米田内也有少量分布。豚草发生、蔓延的原因主要是豚草种子由交通工具、人为裹挟带入及随水流进入农田。对此提出了相应的控制对策。 In order to control the spread and spread of ragweed, we investigated the occurrence and distribution of ragweed in the Ili Valley by means of census and spot observation, and observed its biological characteristics and analyzed its causes. Ragweed is currently mainly distributed in the Yili Valley in some of the townships of Xinyuan County. Corn fields also have a small amount of distribution. Ragweed occurred, the main reason for the spread of ragweed seeds by means of transport, artificially entrained and flow into the farmland. In this regard, the corresponding control measures are proposed.
