| 摘 要： | 应用逐步回归和通径分析，对土壤养分与黑琥珀李株产和冠幅增长的相关关系进行了研究，结果表明，土壤的机质，水解氮，速效磷和速效钾4个养分因子对黑琥珀李株产和冠幅的增长都有着显著和极显著的相关关系，其中以速效磷对产量和冠幅的增长作用最为显著，并且4种土壤养分因子之间存在着相互关联，互为作用的关系，因此，旋肥时应各种营养元素综合考虑，不能偏施。 |

| Abstract: | Studies on relationship between individual yield and crown with soil nutrition by stepwise regression and path analysis showed that 4 nutritional factors such as organic matters, hydrolyzable nitrogen, available phosphorus and available potassium had evident and significant relations with individual yield and crown, especially available phosphorus. Meanwhile, there exist interrelations and interactions among these four soil nutrition, therefore, integrate application of fertilizers is appreciated instead of only one or two. |
| Keywords: | black amber individual yield crown soil nutrition |
