摘要

为探讨科尔沁沙地小叶锦鸡儿固沙群落土壤微生物生物量和酶活性的季节动态规律

选取6

24年生人工群落和天然群落为对象

研究了不同土层深度微生物生物量(C、N、P)和脲酶、蛋白酶、蔗糖酶、磷酸单酯酶、脱氢酶和多酚氧化酶的活性随季节的变化特征。土壤按5层取样:0-10cm

10-20cm

20-30cm

30-40cm

40-50cm。结果表明

6～24年生小叶锦鸡人工固沙群落及天然群落土壤微生物生物量表现出明显的季节性变化

微生物生物量C和N为夏季>秋季>春季;微生物生物量P为夏季>秋季;6种土壤酶的活性也随季节发生显著变化

夏季显著高于春季和秋季。土壤微生物生物量和6种酶的活性随群落发育年限的增长而升高

但人工群落土壤的生物活性始终低于天然群落。6种土壤酶活性和微生物生物量最高值均出现在土壤表层(0-10cm)

随着土层的加深生物活性逐渐降低。

Abstract

The objective of the study was to determine the seasonal dynamics of soil microbial biomass contents and enzymes activities in Caragana microphylla plantations for sand-fixation in the Horqing sandy land.Soil samples at the depths of 0-10 cm

10-20 cm

20-30 cm

30-40 cm

and 40-50 cm were collected from the C.microphylla plantations with an age sequence of 6

and 24 years and from the natural community.The activities of soil urease

protease

saccharase

phosphomonoesterase

dehydrogenase and polyphenol oxidase ...
