- 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。
- Abstract:
- 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.
