| 摘 要： | 采用池栽试验对不同处理土壤的养分及其生物活性的动态变化进行研究.结果表明:(1)烟草长期连作使土壤养分不均衡,土壤脲酶、蔗糖酶和磷酸酶活性下降,微生物量氮含量、细菌和真菌数量减少,而土壤微生物量碳含量逐渐变大.(2)深翻耕促进了土壤氮素转化,减缓了土壤酸化,提高了土壤有机质含量,这有利于烟草生长;深翻耕明显提高了土壤磷... |

| Abstract: | Isolated pools were used to study the dynamic changes of nutrients and biological activity in soil.The results showed that(1) long-term cropping could result in soil nutrient imbalance,reduced urease,phosphatase and sucrase activities,lowered microbial biomass nitrogen,lessened number of bacteria and fungi,and increased microbial biomass carbon;and(2) deep plowing could promote nitrogen transformation,relieve acidification,and increase organic matters in the soil,conducive to tobacco growth.Furthermore,deep... |
