摘　　要：为明确不同浓度矮壮素对藜麦抗倒伏的应用效果,以静藜1号为试验材料,在山西静乐县进行了不同浓度矮壮素对藜麦主要性状及产量的影响试验,分析各浓度与藜麦茎秆抗倒性、节间长度、倒伏表现率等性状的相关性。结果表明,喷施不同浓度的矮壮素对藜麦有一定的增产作用,其中,矮壮素浓度为1.00%~1.25%时,茎秆基部抗折力增加显著,植株较矮,节间缩短,根冠直径和茎秆直径增粗,倒伏指数下降明显。在该试验条件下,藜麦生产上用矮壮素能够抗倒增产,且以高浓度(1.00%~1.25%)喷施节本增效效果最佳。To determine the application effect of different concentrations of chlormequat chloride on quinoa lodging resistance,taking Jingli 1 as the test material,effects of different concentrations of chlormequat chloride on main characters and yield of quinoa were studied in Jingle county,Shanxi province.The correlation of different concentrations with lodging resistance of stem,internode length and lodging rate of quinoa was analyzed.The results showed that different concentrations of chlormequat chloride had a certain effect on quinoa yield increase.When the concentration of chlormequat chloride was 1.00%-1.25%,the bending resistance of the stem base increased significantly,the plant was shorter,the internode shortened,the diameter of root cap and stem increased,and the lodging index decreased significantly.Under the condition of this experiment,the application of chlormequat chloride in quinoa production can resist lodging and increase yield,and the best effect of saving cost and increasing benefit is to spray high concentration(1.00%-1.25%).
