摘    要:以"冀豆12"为材料,在大田条件下通过在初花期对不同群体大豆施用SHK-6,研究了植物生长调节剂SHK-6对不同群体条件下大豆产量及其构成因素的调控作用.结果表明:SHK-6能够明显的提高各个群体下的大豆产量(8.0%),在密度水平为30株/m2的条件下施用SHK-6产量达到最高.调节剂SHK一6能够提高单株花数(13.0%)、荚数(14.8%)、粒数(10.9%)、荚重(16.4%)、粒重(12.3%),并且能够提高百粒重(2.4%)、粒茎比(15.0%).虽然SHK-6处理也增加不同密度水平下的花荚脱落数,但对脱落率没有影响.SHK-6能够降低叶面积指数(LAI)、提高下层叶片的光截获率(群体透光率)和下层叶片的叶绿素的含量.可见冠层结构的优化是导致产量提高的根本原因.

关 键 词:生长调节剂SHK-6  大豆  花荚脱落  产量

Abstract:Field research was conducted to study the effects of SHK-6 application at R1 on soybean yield and yield components in different density using soybean cultivar "Jidou12".The results indicated that SHK6 significantly increased the yield,and the highest yield was observed when applying 100mg/L SHK-6 application at 40 plants/m2.In addition,the following parameters were increased by SHK-6 application: flower number(13.0%),pod number(14.8%) seed number(10.9%),pod weight(16.4%) and seed weight(12.3%) per plant,100-seed weight(2.4%),and seed/stem ratio(15.0%).On the other hand,SHK-6 application also increased the abscission number of flower and pod, but did not affect the percentage of the abscission.SHK-6 application decreased LAI,and increased low-layer canopy light interception and chlorophyll content.This could be responsible for yield increase.
Keywords:SHK-6  Soybean  Abscission of flower and pod  Yield
