    （ 4 ）添加有機、無機物質后，勞去津除草劑污染的三種土壤中微生物生物量碳、氮隨培養時間變化的趨勢基本一致，即0 ~ 7d微生物生物碳、氮降低，但第7d時，添加有機、無機物質的處理中微生物生物量碳、氮均高於僅加養去津的處理和空白對照; 7 ~ 14d微生物生物量碳、氮迅速增加; 14 ~ 42d又下降， 42d后變化較小。
  2. Effect of slow - release fertilizers on yield and quality of trifolium pretense in different soils

    緩釋復合肥對不同土壤紅三葉產量和品質效應的研究
  3. The integrated soil improvement such as application of organic fertilizers, silica fertilizer, and exotic soils, is needed to maintain soil productivity

    也需要施用有機肥、硅肥和客土等綜合土壤改良技術來維持土壤生產力。
  4. Fertilizers and soils conditioners. determination of calcium - egta complexometric method

    肥料和土壤改良劑.鈣- egta絡合滴定法測定
  5. We took atrazine and metsulfuron - methyl as examples to evaluate their dynamics of degradation in soils and the responses of microbial biomass after application of organic matters and fertilizers. the objectives are to find out the relationship among of organic matters / fertilizers added, microbial biomass and herbicides degradation, and for remediation of soils contaminated by herbicides. the main results were summarized as follows : effect of organic matters and fertilizers on microbial biomass in soils contaminated by atrazine / metsulfuron - niethyl herbicides ( l ) the contents of soil microbial biomass c, n and p significantly decreased after application of atrazine at the rate of 22

    與空白對照相比，在淡塗泥田中微生物生物量碳、氮、磷分別平均降低了12 . 37 、 11 . 79和11 . 94 ；在青紫泥田中分別平均降低了10 . 70 、 8 . 43和13 . 66 ；在黃筋泥田中分別平均降低了8 . 55 、 11 . 95 （因其酸度較低，微生物生物量磷的測定方法與前兩種土壤的不同，所以未測定其中的微生物生物量磷的含量） 。
  6. Soil amelioration and ample supply of nutrients in the form of fertilizers is needed to convert poor soils into productive agricultural land

    土壤改良和增施肥料可使這些土壤逐步轉變成具有農業生產力的土壤。
  7. Since these soils are poor soils, ample inputs of fertilizers are needed, beside conservation measures, the use of organic manures and possibly liming of acidic soils

    由於這些土壤肥力低，所以除保護土壤，施用有機肥料，降低酸度外，增施化肥是必需的。
