Study on Nutrients of Dominant Species of Forage and Dynamics of the Rumen Degradability in Old World Bluestem Shrub Rangeland

白羊草灌丛草地优势种牧草营养物质及瘤胃降解动态研究

Results showed that 1 old world bluestem which mainly constitute the old world bluestem Shrub Grassland, had highest degree of dominate, sedge ( Carex spp.)

试验结果表明：1、白羊草灌丛草地以建群种白羊草的优势度最高，其次是苔草、隐子草、达乌里胡枝子等。

The crude protein content of Old World bluestem of three clippings takes on single-peak curve.

Aboveground productivity and soil water characteristics of cultivated Old World bluestem grassland in semi-arid loess hilly-gully areas on the Loess Plateau

半干旱黄土丘陵区白羊草人工草地生产力和土壤水分特征研究

The main conclusions were as follows: 1. Whether in monoculture or mixtures, water stress decreased biomass production of both species and the old world bluestem was more sensitive to water deficiency.

主要结果如下：1.不论在单播或者二者混播条件下，水分胁迫均显著降低白羊草与达乌里胡枝子生物量，且白羊草对水分胁迫的响应更敏感。
