Effects of Diethyl Aminoethyl Hexanoate （DA-6） on Nutrient Absorption of Wild Peach Seedlings

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 different 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.
