【摘要】 在农业生态地质调查基础上,通过对土壤有效态元素及石榴品质的测定,对影响河北省元氏县石榴品质的土壤物理化学因素进行了分析探讨。结果表明土壤母质岩性、母岩裂隙、土壤结构对石榴品质有一定的影响。在元氏丘陵山区片麻岩土、石英片麻岩土中P、K、Mg、Fe、Mn、Zn、B、S、Mo、Na、Mg、Cu、Si有效态元素含量高,母岩裂隙及土壤结构有利于水分及养分的保持和石榴根系吸收,有利于石榴的品质。更多还原

【Abstract】 Based on an extensive agroecological geological survey and by detecting soil availability and quality of megranate, physical geographical and geochemical factors of soil affecting quality of megranate in Yuanshi County of Hebei Province were analyzed. Results indicated that soil lithology, rock cranny and soil structure had a certain impact on quality of megranate. In foothills of Yuanshi County, availability elements such as P, K, Mg, Fe, Mn, Zn, B, S, Mo, Na, Mg, Cu, Si, had high contents in soil containing gneiss and quartzitegneiss. Rock cranny and soil structure are helpful in keeping water moisture and nutrients of soil and in megranate absorption of root systems, and are also helpful in improving the quality of megranate.更多还原
