- 摘要:
- 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10～15 cm的施肥方式最佳，高生长量为14 cm，其次是双点、深度10～15 cm的施肥方式，高生长量为13.4 cm；地径生长量之间呈极显著差异，双点、深度10～15 cm的施肥方式最佳，地径生长量为0.43 cm，其次是三点、深度10～15 cm的施肥方式，地径生长量为0.39 cm；第1分枝生长量之间呈极显著差异，双点、深度2～7 cm的施肥方式最佳，第1分枝长度生长量为5.80 cm，其次是单点、深度2～7 cm的施肥方式，第1分枝长度生长量为0.39 cm。综合分析结果表明，采取深度为10～15 cm、单点或双点的施肥方式，可显著提高核桃容器苗质量。
- Abstract:
- Taking the Juglans regia L. container seedlings as test materials,effect of different fertilizer ways on main growth indices of Juglans regia L. container seedlings were studied,to provide theoretical basis for cultivating fertilization techniques.The results showed that the Juglans regia L. container seedlings height growth was significant difference between different fertilizer way,single point,depth of 10-15 cm fertilization way was the best,plant height was 14 cm；followed by double point,depth of 10-15 cm fertilization way,plant height was 13.4 cm；ground diameter growth was very significant difference between different fertilization way,double point,depth of 10-15 cm fertilization way was the best,ground diameter growth was 0.43 cm,followed by three point,depth of 10-15 cm fertilization way,ground diameter was 0.39 cm；Increment of first lateral branch were very significant difference,double point,depth of 2-7 cm fertilization way was the best,the first lateral branch length was 5.80 cm,followed by was single point,depth of 2-7 cm fertilization way,the first lateral branch length was 0.39 cm.Comprehensive analysis results showed that,took single-point or double point fertilization way,depth of 10-15 cm,could significantly improve the quality of Juglans regia L.container seedlings.
