| 摘 要： | 在网室盆栽条件下,采用3水平灌水量(40,60,80 L/株)×4水平施氮量(0,3,7,12g/株),以烤烟K326为试验材料,研究了水氮耦合对烤烟生育期内土壤过氧化氢酶、蔗糖酶、脲酶和酸性磷酸酶活性动态变化的影响.结果表明,植烟土壤4种酶活性随生育时期推进均呈先上升后下降的趋势,且在旺长期或现蕾期达最高.在相同生育...

| Abstract: | In this article,flue-cured tobacco(Nicotiana tobacum K326)was selected to study effects of water and nitrogen coupling on dynamic changes of soil enzymatic activities of catalase,sucrase,urease and acid phosphatase during the growth stage of flue-cured tobacco by net house cultivation with conditions of 3 levels of water irrigation(40,60 and 80 L/plant)and 4 levels of nitrogen application(0,3,7 and 12 g/plant).The results showed,the soil enzymatic activities of catalase,sucrase,urease and acid phosphatase i... |
