摘要

通过野外挖根试验和室内样品分析测试的研究,测定了2种荒漠植物多枝柽柳和梭梭群落内土壤水分、养分的含量及其分层根系生物量,分析了2种荒漠植物根系生物量的垂直分布与土壤水分、养分之间的关系。结果表明:① 2种荒漠植物的根系生物量随土壤深度的增加逐渐减少,符合指数递减模型,多枝柽柳的根系生物量是同林龄梭梭的2.36倍。② 2种荒漠植物群落内土壤水分含量差异显著,养分差异不显著。③ 2种荒漠植物的根系生物量与土壤水分之间的相关关系显著,其中多枝柽柳与土壤水分呈显著正相关关系,梭梭与土壤水分呈显著负相关关系。表明在干旱区,土壤水分状况对植物根系生长、发育的影响极大。④ 2种荒漠植物根系生物量与土壤养分的相关关系不显著,表明在本地区极端干旱的恶劣环境中,土壤养分不是植物根系生长的限制性因子。

Abstract

With the field work of digging the root and the lab analysis of samples,we have tested the soil moisture and nutrients in the Tamarix ramosissima and Haloxylon ammodendron fields,analyzed the relationship between the vertical distribution of root biomass and the soil moisture and nutrient of two desert plant species. The results showed that: ① With the soil depth increased,the root biomass of two desert plant species gradually reduce,in line with the exponential decline model. The root biomass of Tamarix ramosissima was 2.36 times with the same age of Haloxylon ammodendron. ② The soil water content of two kind of desert plant fields is significant different while there is no significant difference of nutrient.③ The root biomass of two desert plant species had extremely significant relationship with the soil moisture,the correlation coefficient was 0.885 and 0.988,respectively showed that in arid areas,soil moisture conditions had an enormous influence upon the plant root growth and development. ④ There was not significance between the root biomass of two desert plant species and soil nutrient,indicated that in the southern margin of the Taklimakan desert,the soil nutrient is not restrictive factors of plant root growth.
