沿海沙地8个竹种根际土壤的酶活性

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.

Rhizosphere soil enzyme activity of eight kinds of bamboos in seashore dene

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 soil enzyme of Pseudosasa amabilis(McClure)Keng f.,Acidosasa edulis(Wen) wen,Dendrocalamus minor var.amoenus,Dendrocalamopsis oldhami(Munro) Keng f.,D.latiflorus were increased in comparison with bare land;the soil nutrient contents of D.minor var.amoenus,D.oldhami(Munro) Keng f.,P.amabilis(McClure) Keng f.,A.edulis(Wen) wen,D.barbatus H sueb 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 significant correlation between the activities of invertase,cellulase and soil nutrients.
