摘　　要：通过植物生长调节剂处理旱冬瓜苗木,以找出可以加快苗木生长速度的植物生长调节剂,采用不同植物生长调节剂(PP333、NAA、GA3)及其浓度(0mg/L、50mg/L、100mg/L、200mg/L、400mg/L)对旱冬瓜幼苗进行了叶面喷施试验,结果表明:各植物生长调节剂对旱冬瓜苗木各项生理指标都有不同程度的促进作用,GA3、PP333对旱冬瓜苗木的叶绿素含量在浓度为200mg/L时影响最明显。in this paper,the plant growth regulator was used to deal with the seedlings of Alnus nepalensis,and to find the plant growth regulators that could accelerate the growth rate of seedlings.The mainly adopts different plant growth regulator（PP333,NAA,GA3）and concentration（0 mg/L,50 mg/L,100 mg/L,200 mg/L,400 mg/L）for spraying on the leaf Alnus nepalensis seedling test,different plant growth regulators on physiological indexes in the drought white gourd seedlings have different degrees of promoting function,GA3,PP333 in Alnus nepalensis seedling chlorophyll concentration of 200 mg/L was the most obvious.
