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, D2d2地层最优, Q p地层其次, C3地层最劣与板栗生长呈正相关的元素有 K, Na, M n, B, Zn, V ;呈负相关的元素有 Ca, Cu, F , Se, Ga
 

Abstract

Based on the investigation of growth and yield in different stratum for chestnut ( Castanea mollissima Blume) in Longan 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 show ed that the yield of chestnut differed greatly on different stratum, D2d2 stratum is the best, Qp take second place and C3 is bad .The growth of chestnut trees were positively correlated with the content of K, Na, M n, B, Zn, V elements, and were negatively correlated with Ca, Cu, F, Se, Ga elements .
