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。

This paper is to study the activity of saccharase and the relation between the activity and the soil organic matter and all the nitrogen.

本试验是探索转化酶的活性及其与土壤有机质和全氮的关系。

The experiment has signified: if the rice soil of fertility level is higher, the activity of saccharase is stronger;

肥力水平较高的水稻土，转化酶的活性较强；

Simultaneously, the activities of catalase, protease, phosphatase and saccharase decreased in M. prunifolia rhizosphere soil exposed to root leachate. 6.

同时，根系浸提液处理降低了根际土壤的过氧化氢酶、蛋白酶、磷酸酶和蔗糖酶活性。

The effects of ecological improvement on soil were expressed as follows: saccharase neutral phosphatase urease catalase.

生态改良对土壤中四种酶活性的影响大小依次为：蔗糖酶脲酶中性磷酸酶过氧化氢酶。

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。

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。
