以核桃(Juglans regia L.)容器苗为试材,研究了不同施肥方式对其主要形态生长指标的影响。结果表明:不同施肥方式核桃容器苗高生长量之间呈极显著差异,单点、深度10~15cm的施肥方式最佳,高生长量为14cm,其次是双点、深度10~15cm的施肥方式,高生长量为13.4cm;地径生长量之间呈极显著差异,双点、深度10~15cm的施肥方式最佳,地径生长量为0.43cm,其次是三点、深度10~15cm的施肥方式,地径生长量为0.39cm;第1分枝生长量之间呈极显著差异,双点、深度2~7cm的施肥方式最佳,第1分枝长度生长量为5.80cm,其次是单点、深度2~7cm的施肥方式,第1分枝长度生长量为0.39cm。综合分析结果表明,采取深度为10~15cm、单点或双点的施肥方式,可显著提高核桃容器苗质量。
Taking container seedlings of Juglans regia L. as test materials, the effects of different fertilization methods on its main morphological growth indexes were studied. The results showed that there was a significant difference in the growth of walnut seedlings between different fertilization methods. The single-point and depth 10-15 cm fertilization method was the best, the high growth rate was 14 cm, followed by the double point and the depth of 10 ~ 15 cm fertilization , And the high growth rate was 13.4 cm. There was a significant difference in the growth of ground diameter between the two points. The depth of 10 to 15 cm was the best. The growth of soil diameter was 0.43 cm, followed by three points and the depth of 10-15 cm Fertilization mode, the diameter growth was 0.39cm; the first branch growth was significantly different between the two points, the depth of 2 ~ 7cm fertilization best way, the first branch length growth was 5.80cm, followed by Single point, the depth of 2 ~ 7cm fertilization, the first branch length growth of 0.39cm. The results of comprehensive analysis showed that the quality of walnut seedlings could be significantly improved by adopting single or double point fertilization mode with the depth of 10 ~ 15cm.
