摘要
通过对广西隆安县板栗产区不同地层板栗生长状况和产量的调查，划分板栗的适生地层，并通过母岩、土壤、板栗植株元素含量的分析，研究对板栗生长产生影响的元素。结果表明：不同地层上板栗产量差异显著，以Ｄ２ｄ２地层最优，Ｑｐ地层其次，Ｃ３地层最劣。与板栗生长呈正相关的元素有Ｋ，Ｎａ，Ｍｎ，Ｂ，Ｚｎ，Ｖ等；呈负相关的元素有Ｃａ，Ｃｕ，Ｆ，Ｓｅ。
Based on the investigation of growth and yield in different stratum for chestnut ( Castanea mollissima Blume) in Long′an county, Guangxi, the suitable stratum for plantation is divided. Through sampling test of element contents in rocks, soils and plants of different stratum, the main elements affecting the growth of chestnut were studied. The results showed that the yield of chestnut differed greatly on different stratum, D 2d 2 stratum is the best, Q p take second place and C 3 is bad. The growth of chestnut trees were positively correlated with the content of K, Na, Mn, B, Zn, V elements, and were negatively correlated with Ca, Cu, F, Se, Ga elements.
