不同轮牧方式下的宁夏荒漠草原土壤性质分异特征
Features of Desert Steppe on Soil Characteristics under Different Rotation Grazing Modes
摘要
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 results showed that under the same grazing intensity, increasing the numbers of rotation grazing areas was advantageous to keep the content of the soil organic matter,total N, soluble salt and quickly available P (P＜0.05).The effects of rotation grazing on quickly available K content and pH were not notable (P＞0. 05), but the content of hydrolysable nitrogen decreased. Increasing the numbers of rotation grazing areas increased the clay particles content of soil surface layer (0-5 cm).关键词
