摘　　要：为研究大豆花荚脱落情况,以大豆(Glycine max)垦农4号为材料,在R1期叶面喷施3种不同植物生长调节剂,调查了大豆植株花数、荚数以及花荚脱落数。结果表明:氯化胆碱(Cc)明显的增加了大豆植株的花数及荚数。2-N,N-二乙氨基乙基己酸酯(DTA-6)和SODM有效降低了花荚脱落数以及脱落率;其中DTA-6还显著增加了大豆株高和茎粗,提高了单株粒数、单株粒重以及单株重等产量构成因子,增产幅度为13.24%。可见叶面喷施Cc有效地促进了开花结荚,而在产量增幅上,DTA-6为最佳。The abscission of flower and pod is one of main problems affecting grain yield of soybean. In the present study, three PGRs of SOD simulation material （SODM ）, Choline chloride （Cc） and Diethyl aminoethyl hexanoate （DTA-6）were sprayed at R1 stage with soybean cultivar Kennong 4 as material, and the effect of PGRs on abscission of flowers and pods was determined. Compared with CK,the number of flower and pod significantly increased under Cc treatment. DTA-6 and SODM effectively reduced the abscission number of flower and pod ;DTA-6 markedly enhanced plant height, stem diameter, and yield structures. 13.24 % of yield increases were obtained under DTA-6 treatment. Results suggest that it is effective to enhance the numbers of flower and pod by spraying Cc and DTA-6 on soybean leaves, and DTA-6 had better yield increasing effect.
