摘要: 在呼伦贝尔盟东南部(主要指阿荣旗、布特哈旗和扎赉特旗)的甸子地约有668万由,占本区荒地总面积的91.5%。开垦后的甸子地,土质肥沃,单产较高。但是,在农业生产上,群众普遍反映甸子地“地凉”,比坡地易遭初霜危害,单产不稳。

Abstract: The microclimatological contrast observations in the wetland of Southeast Hulunbir are conducted. The result shows that cold injury to agriculture in the wetland was mainly caused by too high ground water level and too much water content in the soils. The experiments indicated that if the north-south ridge cultivation method is adopted or the method by adding sands to the soil, the soil temperature and crpos yield may rise.
