摘要
通过室内测定 ,明确了不同棉花品种对盖草能的耐药性存在较大差异。春矮早的种根、种芽耐药性较强 ,高抗 5号种根、种芽耐药性较弱 ,使用不当 ,易产生药害。 42 2、豫棉 1 3号的种根、种芽的耐药性居中。品种×浓度互作结果表明 :春矮早、42 2以 40 μg/kg为优 ,高抗 5号、豫棉 1 3号以 2 0～ 40 μg/kg为佳 。
Tolerance of different cotton varieties to Gallant had very big difference through sensitiveness test experiment.The root and shoot of Chunaizao could endure Gallant best,while root and shoot of Gaokang 5 endured Gallant poorly.So Gallant should be used properly in land or it's easy to cause harm.Root and shoot of 422 and Yumian 13 could endure Gallant moderately.The results of mutual effect between varieties and contentration showed that 40 μg/kg was good to Chunaizao and 422 and 20-40 μg/kg was good to Gaokang 5 and Yumian 13.At the same time they were in conformity with quantity in field.
