摘要
研究了二甲戊乐灵的施用深度和剂量对棉苗生长发育的影响。结果表明,二甲戊乐灵在4 cm药层以上抑制侧根的增加和主根的生长,而在4 cm以下的根生长发育正常。33%二甲戊乐灵3 000 mL/hm2以上高浓度下抑制了侧根的生长,而对主根的干重、长度以及植株的鲜重影响较小。
The effects of madicine layer depth and medicine dosage used of stomp（pendimethalin） on growth and development of cotton seedling were studied.The results showed that pendimethalin inhibitsed the lateral root and tap root growth of cotton seedling when the medicine layer was above 4 cm,but roots grew normally when the medicine layer was below 4 cm.Pendimethalin inhibited lateral root to grow when the medicine concentration used was above 3 000 mL/hm2,but presented a weak effecs on dry weight,length of taprvots and the fresh weight of cotton seedling.
