摘　　要：为了促进果树生长和对土壤养分的吸收,试验以桃幼苗为材料,研究了腐殖酸对桃幼苗生长及养分吸收的影响。结果表明:腐殖酸处理对桃幼苗的生长及养分吸收均有促进作用,且以腐殖酸稀释倍数为900倍时促进作用最好;在腐殖酸稀释倍数为900倍时,桃幼苗根系和地上部分生物量达到最大,桃幼苗地上部分全氮、全磷和全钾含量分别较对照提高了29.21%、66.91%和21.61%。因此,腐殖酸能够促进桃幼苗的生长与养分吸收,且最佳稀释倍数为900倍。To promote the growth of fruit trees and the absorption of soil nutrients,the effects of humic acid on the growth and nutrient absorption of peach seedlings were investigated.The study demonstrated that humic acid promoted the growth and nutrient absorption of peach seedlings,and the biomass of roots and shoots of peach seedlings reached the maximum levels at a 900-fold dilution of humic acid.Moreover,the content of total nitrogen,total phosphorus,and total potassium in the shoots of peach seedlings increased by 29.21%,66.91%,and 21.61%,respectively,compared with the control.Therefore,humic acid is effective in enhancing the growth and nutrient absorption of peach seedlings,with the best outcomes observed at a dilution factor of 900.
