河北行唐大枣品质与成土母岩类型关系的探讨

Based on the study of a chronosequence of soils, developed from basalts erupted in different geological times, in the northern Hainan island, the variation of soil properties with soil age increasing in its development has been discussed quantitatively.

海南岛北部不同时期喷发的玄武岩上发育的土壤构成一个成土年代系列 ,由此可以定量地探讨发育过程中土壤性质随风化成土年龄增加的变化规律 。

In this study,soil formation rates(SR) of the purple soils(a Regosols) in the hilly area of Sichuan,China were determined by Barth equation(SR-estimated) and field measurements(SR-measured) with the three treatments of soil types(J1s,J3s,and J3p soils),vegetations(wheat-maize,loquat tree,and ryegrass),and soil depths(10,20,40,and 60 cm).

应用以物质循环理论为基础的Barth模型,估算了不同母质类型,不同种植植被和不同土层厚度下的成土速率,并在田间定位试验点测定了这3种不同处理条件下的成土速率。
