    摘要:

    为建立一个低成本、易推广的苏打草甸碱土植被的快速重建模式,在试验区内随机选取碱斑,直接在碱斑上堆肥。结果表明:灌水+堆肥与常规堆肥盐分调控的效果最好。堆肥浇水处理的出苗率显著高于未浇水处理,秋季浇水与未浇水处理生物量没有差异。碱斑上经过人工植被建植后,草甸碱土上植物群落已演替到羊草+盐碱植物群落阶段,跨越了盐碱植物群落阶段。碱斑上直接进行常规堆肥是苏打草甸碱土植被重建的快速、经济模式。

    Abstract:

    In order to establish a low-cost and easy-to-extend mode of rapid vegetation rehabilitation,alkali spots were selected at random as composting sites in the experiment zone of soda meadow alkaline soil in Huo Chetou Village,Zhaozhou County,Heilongjiang Province.Composting was done directly on the alkali spots.Results showed that conventional composting and irrigated composting was better than others in controlling soil salt content.The treatment of irrigated composting was obviously higher than other treatments in seedling emergence rate,but did not differ much from the latter in biomass of plants in fall.After artificial vegetation rehabilitation,the plant community on the alkali spots already skipped over the stage of community of halophytic plants to the stage of community of Aneurolepidium chinense plus halophytic plants.To do conventional composting on alkali spots is an economical code of rapid vegetation rehabilitation in soda meadow alkaline soils.
