摘　　要：为了降低藜麦株高和提高抗倒伏能力,不同生长期叶面喷施不同浓度矮壮素,研究了不同处理对藜麦农艺性状、光合特性和产量构成因素的影响。结果表明:藜麦叶面喷施矮壮素后均降低了株高,提高了产量,但不同时期喷施不同浓度的效果差异较大。相同喷施浓度条件下,旺盛生长前期喷施的效果优于旺盛生长后期,不同处理中A_(2)B_(1)(0.3%矮壮素+旺盛生长前期喷施)的综合效果最佳,建议在藜麦种植中推广应用。In order to decrease height and increase lodging resistant ability of Chenopodium quinoa Willd,the effects of different treatment on economical character,photosynthetic properties and yield component of Chenopodium quinoa Willd were studied after different consistence CCC were sprayed in different time.The result showed that the plant height were decreased,and the yield were increased after different consistence CCC were sprayed on leaves,and the effect differences of different consistence sprayed in different time were large.Under the same spraying concentration,the effect of spraying in the early stage of vigorous growth is better than that in the later stage of vigorous growth,and the comprehensive effect of A_(2)B_(1)(0.3%CCC+sprayed in strong growth early)was best in all treatments and it is recommended to promote and apply in planting.
