缩节胺(又称助壮素)是一种内吸性植物生长调节剂,可抑制细胞和节间伸长,药效比较缓和。持续时间较长、安全幅度较大,使用成本低、经济效益好。但如果施用不当,不仅达不到控制效果,甚至会造成花蕾脱落,结桃少而壳厚,成熟晚。目前市场上销售的成品有粉剂与水剂两种。水剂相对安全可靠,面粉剂不好把握。
Diammonium (also known as mepiquat chloride) is a systemic plant growth regulator, can inhibit cell and internodal elongation, efficacy more moderate.

Finished products currently on the market are two kinds of powder and water agent. Relatively safe liquid reagent, flour agent is not good grasp.
