摘要:
对不同季节油茶根际与非根际土壤养分含量和微生物数量的变化进行研究。结果表明：(1)由春季到冬季，油茶可溶性蛋白、可溶性糖、叶绿素、叶片氮和叶片磷含量呈先增加后降低趋势，大致表现为夏季>秋季>春季>冬季。(2)不同季节油茶根际与非根际土壤理化性质随季节变化趋势相一致，由春季到冬季油茶根际与非根际土壤pH值呈先降低后增加趋势，大致表现为冬季>春季>秋季>夏季，以夏季油茶根际与非根际土壤pH值最低。(3)不同季节油茶根际与非根际土壤养分含量和土壤微生物数量随季节变化趋势相一致，由春季到冬季，油茶根际与非根际土壤养分含量和微生物数量均呈先增加后降低趋势，大致表现为夏季>秋季>春季>冬季，局部有所波动，其中油茶根际土壤养分含量和微生物数量在夏季、秋季表现出了明显的“根际富集”。(4)不同季节油茶根际与非根际土壤微生物均以细菌最多，占微生物总数的90%以上，其次是放线菌、真菌，表明不同季节根际土壤对于不同微生物菌落有着不同的效果，但总体来说，油茶的根际养分的富集提高了微生物总数。(5)油茶根际、非根际土壤pH值与土壤养分含量、微生物数量达到显著或极显著负相关，土壤养分含量和土壤微生物数量之间也达到显著或极显著正相关，表明油茶根际和非根际土壤养分含量、微生物数量变化趋势基本保持一致，主要可以通过降低根际pH值提高根际养分含量，有利于对土壤养分的有效利用。
