【摘要】 用Folin—Ciocalteu比色法测定了土壤微生物蛋白酶。在流动沙地中,土壤微生物蛋白酶的季节变化为夏季>春季>秋季>冬季,垂直变化为10~20cm>2~5cm>5~10cm>0~2cm。在半固定和固定沙地中,土壤微生物蛋白酶的季节变化为夏季>秋季>春季>冬季,垂直变化为0~2cm>2~5cm>5~10cm>10~20cm。在半固定沙地中无结皮样地的土壤微生物蛋白酶含量大于藻结皮的,在固定沙地中藓结皮样地的土壤微生物蛋白酶的含量大于藻结皮样地的大于无结皮样地的。
【Abstract】 Use the colorimetry method of Folin-Ciocalteu to measurement prolease content of soil microorganism.On flow sandlot,the seasonal changes of soil prolease is summer>spring>fall>winter; the vertical veriability is 10~20cm>2~5cm>5~10cm>0~2cm.On the half fixed and fixed sandlot, the seasonal changes of soil prolease is summer>fall>spring>winter;the vertical veriability is 0~2cm>2~5cm>5~10cm>10~20cm.On the half fixed sandlot,the prolease content of test plot with no fur is more than test plot with elegant fur;on the fixed sandlot,the prolease content of test plot with mos- ses fur is more than test plot with elegant fur,the test plot with elegant fur is more than test plot with no fur.
