摘要

为进一步研究放牧对草地生态系统非生物环境(土壤)的影响机制

试验以宁夏盐池县四墩子行政村荒漠草原为研究对象

采用野外定位试验和室内分析的方法分别研究了禁牧(CK)、自由放牧(A)、2区轮牧(B)、4区轮牧(C)和6区轮牧(D)条件下的0-5

5-15

5-25 cm土层的土壤理化性质的变化

并对各处理的土壤理化性质用ANOVA法进行差异性分析。结果表明:放牧强度相同时

增加轮牧分区数有利于土壤有机质、全氮、可溶性总盐、速效磷的保持(P<0.05)

影响较大的土层为0-5 cm和5-15 cm;轮牧对速效钾含量和pH值的影响不大(P>0.05)

但使水解氮含量降低(P<0.05);轮牧分区的增加有利于土壤表层(0-5 cm)粘粒的形成。

Abstract

In order to study the effect on the grassland abiotic environment(soil) of grazing

the research object was the desert sttepe of Sidunzi administrative village in Yanchi county

Ningxia.Using locating field experiment and indoor process analyzed effects on properties of different depth of soil(0-5

5-15

15-25 cm) under different rotation grazing modes in desert steppe including no grazing(CK)

freely herd(A)

two areas rotational grazing(B)

four areas rotational grazing(C) and six areas rotational grazing(D).The...
