中文摘要：
为了分析秸秆覆盖和种植耐盐碱牧草对盐碱土壤的影响，本研究通过田间裂区试验，比较了在采取不同的改良措施下，盐碱土壤养分含量及微生物数量的变化情况。结果表明：秸秆覆盖和种植耐盐碱牧草可改变土壤养分及微生物含量，但并不是所有覆盖量以及所有耐盐碱牧草均适宜，研究发现，当覆盖量为2kg／m2时，种植一年生牧草东饲一号稗草对土壤的改良效果较好。
英文摘要：
The influence of straw mulching and planting forage grass on alkali soil was studied by split plot design. This experiment analyzed the changes of soil nutrient and soil microbial biomass under the two soil improvement methods. The results revealed that the measures of straw mulching and planting forage grass were good for soil im- provement such as soil nutrient contents and microbial biomass to certain extent but not on all foraging grass. Among all the methods, the effect of planting Echinochloa crusgalli with the mulching quantity of 2 kilograms for every square meter had an ideal result.
