saccharase

Fungi in the rhizosphere during FPS inhibited remarkably the activities of saccharase and urease, bacteria in the soil promoted the activities of saccharase, bacteria in the soil and actinomyces in the rhizosphere in PFS promoted remarkably the activities of urease.

花针期根际真菌显著抑制蔗糖酶和脲酶活性，土壤细菌显著促进蔗糖酶活性，土壤细菌、成熟期根际放线菌显著促进脲酶活性。

In the Loess area, the catalase, urease, phosphatase and saccharase activities in rhizosphere soil of 6 years old walnut decreased with the depth of spatial profile, indicated that the soil enzymes activities may be related with the root secretion.

渭北黄土区6年生核桃根际土壤的过氧化氢酶、脲酶、磷酸酶和蔗糖酶活性的空间变化随着土层剖面的加深而活性降低，说明土壤中各种酶的活性可能和核桃根系的分泌物有关。

After fertilization of corn straw for 2 months, Soil saccharase, urease and catalase activities enhanced with the dosage increased, but changed a little when the usage beyond 1.2%.

4个月后，玉米秸用量为1.2%的处理土壤脲酶、蔗糖酶、过氧化氢酶活性最高。施用麦秸的处理土壤脲酶、蔗糖酶、过氧化氢酶活性均随用量增加而升高。
