应用逐步回归和通径分析，对土壤养分与板栗株产和徒长枝生长的相关关系进行研究，结果表明，所选的有机质、水解氮、速效磷和速效钾4个土壤养分因子对板栗株产和徒长枝的生长都有着显著和极显著的相关关系，其中以速效磷对产量影响最为显著，水解氮对徒长枝生长影响最为显著。其作用既有直接的，又有间接的，既有正作用，又有负作用，且4种土壤养分因子之间也存在着这种相互联系、相互影响、相互作用的关系。4 种土壤养分因子对板栗株产作用的剩余系数有 0.406 3，说明还有部分相关因素 (如密度、微量元素、土壤的水气热、pH值) 尚未包括在内。因此，板栗施肥时应综合考虑各种营养元素，不能偏施。

Relationship between soil nutrient and growth of Castanea mollissima was studied by stepwise regress and Path analysis.The results showed that, 4 soil factors of organic matter, hydrolytic nitrogen,rapid phosphorus and rapid potassium had significant effects on its yield and growth of fliage branch, and that the most significant factors affecting yield and growth of foliage branch were rapid phosphorus and hydrolytic nitrogen, respectively. Residual coefficent of effects of 4 soil factors on yield was 0.4063, showing that there were other factors not to be included.Therefore, in fertilizing for Castanea mollissima, nutrient elements should be completely considered.
