绿麦隆在麦田土壤中残留动态及其对后茬作物生长的影响

Research on the Residual Dynamics and the Effects of the Herbicide Chlortoluron in Wheat Field on the Successive Crops.

本文通过田间小区和盆栽试验的方法研究了除草剂绿麦隆在土壤中的残留动态及其对后茬作物生长的影响。研究结果表明,以常规用药量的1—5倍施用于麦田,其在田间的残留不会对后茬作物的生长造成危害。而当其在田间残留量达到或超过0.30mg/kg时,对后茬作物的生长就会产生明显的危害作用。

The residual dynamics and the effects of chlortoluron on growth of the successive crops were studied. The results showed that the residues of the herbicide in soil did not influence the growth of the successive crop(rice) at the dosages up to fivefold of that is commonly used. However, when the residues in soil were 0.3mg/kg and above, the successive crop can be damaged obviously.
