摘　　要：通过田间试验,研究了叶片喷施不同浓度矮壮素和施用时期对食用向日葵辽嗑杂6号株高和单株籽粒产量的影响。结果表明,叶面喷施矮壮素可以降低食葵辽嗑杂6号的株高。随着矮壮素浓度的增加,辽嗑杂6号株高降低幅度增加,但是单株籽粒产量随浓度的增加而逐渐降低。苗后28 d和35 d施用矮壮素,株高分别降低16.75%和11.96%。随着施用时期的延后,单株籽粒产量减产幅度降低。Through field experiments,the effects of spraying different concentrations of Chlormequat Chloride(CCC)on leaves and application time on plant height and grain yield per plant of edible sunflower Liao Keza 6 were studied.The results showed that spraying CCC on foliage can reduce the plant height of Liao Keza 6.With the increase of CCC concentration,the decrease in plant height of Liao Keza 6 increased,but the grain yield per plant decreased gradually with the increase of concentration.The plant height decreased by 16.75%and 11.96%by applying CCC 28 and 35 days after seedling.With the extension of the application period,the yield reduction rate of the grain yield per plant decreased.
