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

白羊草灌叢草地優(yōu)勢(shì)種牧草營(yíng)養(yǎng)物質(zhì)及瘤胃降解動(dòng)態(tài)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.)

試驗(yàn)結(jié)果表明：1、白羊草灌叢草地以建群種白羊草的優(yōu)勢(shì)度最高，其次是苔草、隱子草、達(dá)烏里胡枝子等。

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

三次刈割的粗蛋白質(zhì)含量呈現(xiàn)1茬低、2茬高、3茬低的單峰曲線(xiàn).

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

半干旱黃土丘陵區(qū)白羊草人工草地生產(chǎn)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.

主要結(jié)果如下：1.不論在單播或者二者混播條件下，水分脅迫均顯著降低白羊草與達(dá)烏里胡枝子生物量，且白羊草對(duì)水分脅迫的響應(yīng)更敏感。
