安徽宁国市山核桃农业地质环境的因子分析研究
|
摘要
利用SPSS软件,研究因子分析在宁国市山核桃农业地质环境中的应用。以植物生长有关的11种微量元素为指标,分析了不同长势的山核桃果、叶与岩石、土壤、成土母质微量元素之间的联系。研究表明:岩石、土壤、成土母质中的Mo、Cu、B、Co、N i、Zn、Cr等元素的丰度与宁国山核桃的生长发育密切相关;少数元素的差异,如Fe、Mn、Se等元素,可能对于山核桃长势及产量具有一定的制约作用或起决定性因素。
The application of Factor analysis in agro-geological environment of Carya Cathayensis in Ningguo City,Anhui Province was studied.Using eleven trace elements as the indexes,the interrelations between the fruits and leafs of Carya Cathayensis under different growth conditions in rocks,soils and matrixes were analyzed.The results showsed that the contents of Mo,Cu,B,Co,Ni,Zn and Cr in rocks,soils and matrixes closely related to the growth of Carya Cathayensis.The differences in contents ofsome elements,such as Fe,Mn and Se probably had some restrictive or decisive effects on the growth and output of Carya Cathayensis.
