研究了B9和S33072种药剂的不同浓度对大丽花植株生长的影响,结果表明:B9和S3307对大丽花植株有极显著的矮化作用,并且随着处理浓度的增加对植株的抑制效果越明显,其中:浓度为20mg/L的S3307对大丽花植株的矮化效果最好。
The effects of different concentrations of B9 and S33072 on the plant growth of Dahlia were studied. The results showed that B9 and S3307 had extremely significant dwarfing effect on Dahurica plants, and the more obvious their inhibitory effect was, : S3307 at a concentration of 20 mg / L had the best dwarf effect on dahlia plants.
