摘要
对沿海沙地8个竹种根际土壤的酶活性和土壤养分进行测定分析,结果表明:茶杆竹、黄甜竹、花吊丝竹、绿竹、麻竹根际土壤的酶活性都比裸地高;花吊丝竹、绿竹、茶杆竹、黄甜竹、小叶龙竹、麻竹根际土壤的有机质含量以及氮、磷、钾元素含量均高于其他竹种,且显著高于裸地.相关性分析表明,酶活性与pH呈负相关,有机质含量与酶活性呈显著正相关,而蔗糖酶、纤维素酶活性与土壤养分含量呈极显著或显著正相关.
The rhizosphere soil enzyme activity and nutrient contents of eight kinds of bamboos in seashore dene were studied, the results were as follows: the activities of soft enzyme of Pseudosasa amabilis (McClure) Keng f. , Acidosasa edulis (Wen) wen, Dendrocalamus minor vat. amoenus, Dendrocalamopsis oldhami (Munro) Keng f. , D./at/florus were increased in comparison with bare land; the soil nutrient contents of D. minor var. amoenus, D. oldhaml (Munro) Keng f. , P. amabilis (McClure) Keng f. , A. edulis (Wen) wen, D. barbatus H sueh et D. Z. Li, D.latiflorus were higher than those of other kinds of bamboos, and also higher than that in bare land; correlation analysis showed that there was a negative correlation between soil enzyme activity and pH, there was a significant positive correlation between soil enzyme activity and soil organic matter content, there was significant or extremely signifi- cant correlation between the activities of invertase, cellulase and soil nutrients.
