摘要
通过对生长素（IAA）和缩节胺（DPC）在棉花上使用方法的研究，发现IAA能显著促进棉株生长，DPC则能有效地抑制棉株生长。IAA和DPC对塑造棉花理想株型有显著作用，若使用方法得当则能获得增产。IAA和DPC的最佳使用方法为苗期喷施IAA100mg／L和初花期喷施DPC50mg／L。
In this paper the usage method of Indoleacetic acid(IAA) and dimethyl piperdine chloride (DPC)on cotton seedlings was studied under field codations,the results showed that IAA can markedly promoted cotton seedlints growth. But DPC can effectively inhibited cotton seedlings grouth IAA and DPC coed increased fiber Yield of cotton, in ulcich spatted 100mg/LIAA in seedling period and 50mg/L DPC in early- flower peried to cotton plants was better.
