摘　　要：盐碱土在经过客土法与新土源法改良后,土壤生态环境会显著得到改善.能显著提高土壤微生物数量、增强土壤生物活性,能降低土壤盐分、增加土壤有机质含量、改善土壤肥力.通过客土法改良,土壤生物化学作用强度较高,新土法改良后土壤微生物数量较多,新土源更有利于微生物生长繁殖.It has been shown that Guest Soil and New Soil could be used to saline -alkaline soil and improve much the ecological environment of soil, increasing soil biochemical numbers, strengthening soil biochemical activities, reducing soil salt. It can improve soil organic matter and fertility too. After the soil is improved in either way , the salt content has decreased and the organic matter content has increased. The New Soil is more favorable for the growth of microorganism.

关 键 词：盐碱土 改良 土壤环境 土壤肥力
