3) alkali soil
碱性土壤
1.
Current circumstances and mechanisms were reviewed in detail about application of the gypsum in acid soil and alkali soil.
简述了脱离石膏的工业利用,详述了脱离石膏对酸性和碱性土壤改良的现状和机理,并展望了脱硫石膏促进滩涂土植被演替的前景。
4) alkaline soil
碱性土壤
1.
Four soluble inorganic salts were used to study their influences upon cadmium forms in the alkaline soil and contents of cadmium absorbed by plants in the experiment.

水稻田土壤
1.
The contribution of anaerobic methane oxidation to the whole methane oxidation is investigated by monitoring the activities of anaerobic and aerobic oxidation of methane in paddy soils composed mechanically of <0.
对黄松土水田土壤中>0·02mm的颗粒和<0·02mm的颗粒按不同比例组合成的土壤、不同绝对含水量的黄松土水田土壤、不同温育时段的水田土壤和长期定位不同施肥的水稻田土壤中的甲烷好氧氧化和厌氧氧化的速率的检测结果进行比较,结果相当一致,不仅证实了水稻田土壤甲烷厌氧氧化过程的存在,而且表明水田土壤中的甲烷厌氧氧化活性远较甲烷好氧氧化活性要低,如以两者的氧化活性作为对甲烷氧化的贡献来计,则甲烷厌氧氧化的贡献率一般都在整个甲烷氧化的10%以下。
2.
