Sucrase an enzyme that breaks down sucrose into glucose and fructose 蔗糖酶：使蔗糖分解成为葡萄糖和果糖的酶。
2.
The activity of sucrase had insignificant correlation to the environmental factors 与环境因子无显著的相关关系。
3.
From bare flat to reed zone , the activity of sucrase changed insignificantly . there was a higher activity in triangle sulbush ( 5c / rp 转化酶活性从光滩到芦苇带变化并不明显，在海三棱蔗草带略高。
4.
Meanwhile , in order to improve the e . coli with ability of using sugar . we have recombined the vecter of parg25 a which have ability of using sugar with the gene of sucrase length of 7800bp 同时，为了促进所构建的大肠杆菌具有蔗糖利用能力，我们构建了含有大小为7 . 8kb的蔗糖水解酶基因sacc重组质粒，筛选得到含有两种基因的重组子，并转化大肠杆菌，使大肠杆菌获得蔗糖利用能力。

The result showed that organo - inorgano - mixed fertilizer could increase the quantity of availability , strengthen the activity of proteinase , sucrase , urase and peroxidase in the sugarcane roots , and increase the sugarcane yield and sugar content 结果表明，有机无机肥料配施，可提高土壤有效养分的含量，激活土壤蔗糖酶、脲酶、蛋白酶、过氧化物酶的活性，促进甘蔗生长与蔗糖分的累积，对甘蔗增产增糖有积极的作用。
6.
The results showed with the application of coated compound fertilizer , the activities of soil urease , neutra phosphatase , catalase and sucrase were better than compound fertilizer treatment because of the significantly controlled release effects of the coated compound fertilizer 结果表明，在试验条件下，由于包膜复合肥对养分的显著控释效果，它的施用对土壤脲酶、中性磷酸酶、过氧化氢酶和蔗糖酶活性的影响要好于普通肥料处理。

From the aspects of agricultural economic and environmental ecological effects , were the effects and mechanism of rare - earth micro - fertilizer to improve the growth , development , quality and yield of the crops ; the adjustment of crops growth by influencing the number of microbial population in soil district and the function of the soil dehydrase , alkaline phosphatase , urease and sucrase ; the ecophysiological effects of alleviating the injure of acid rain , ultraviolet radiation , heavy metal on crops were illustrated ; the sureness of bee ' s use in agricultural was provided , according to the rule of the distribution and enrichment of be in crops 摘要从农业经济效应和环境生态效应二方面，论述了稀土肥料促进作物生长、发育，提高作物产量，改善作物品质的效应与机理；影响土壤区系中微生物种群数量和土壤脱氢酶、碱性磷酸酶、脲酶及蔗糖酶的功能，继而反馈调节作物生长；缓解酸雨、紫外辐射和重金属伤害作物的生态生理学效应；并以稀土在作物体内分布与富集规律为参考，探讨了稀土农用的安全性。
