摘　　要：为促进果树砧木对养分的吸收,通过盆栽试验,研究了喷施不同浓度的胺鲜酯(DA-6)溶液对毛桃幼苗养分吸收的影响,以期筛选出最适宜毛桃幼苗养分吸收的DA-6浓度。结果表明,不同浓度的DA-6均显著提高了毛桃幼苗根系、茎杆、叶片以及地上部分的全氮、全磷和全钾含量,其中浓度为30 mg·L^(-1)的DA-6处理最大。与对照相比,浓度为30 mg·L^(-1)的DA-6处理的毛桃幼苗根系、茎杆、叶片和地上部分全氮含量分别增加了77.36%、220.52%、48.14%和77.49%,全磷含量分别增加了19.94%、49.84%、18.40%和23.85%,全钾含量分别增加了20.85%、15.99%、41.77%和34.18%。因此,DA-6可促进毛桃幼苗对养分的吸收。To promote the absorption uptakes in rootstocks of fruit trees,a pot experiments was conducted to study the effects of spraying the different concentrations of diethyl aminoethyl hexanoate(DA-6)solution on nutrient absorption in wild peach seedlings.The aim of this study was to screen the most appropriate concentration of DA-6 for nutrient absorption in wild peach seedlings.The results showed that the differe nt concentrations of DA-6 increased the total nitrogen(N),total phosphorus(P)and total potassium(K)contents in roots,stems,leaves and shoots of wild peach seedlings,and the concentration of 30 mg·L^(-1) DA-6 had the greatest effect.Compared with the control,the concentration of 30 mg·L^(-1) DA-6 increased the total N contents in roots,stems,leaves and shoots of wild peach seedlings by 77.36%,220.52%,48.14%and 77.49%,respectively,the total P contents increased by 19.94%,49.84%,18.40%and 23.85%,respectively,and the total K contents increased by 20.85%,15.99%,41.77%and 34.18%,respectively.Therefore,DA-6 could promote the nutrient absorption in wild peach seedlings.
