轮作改变了氨挥发速率的变化规律,现蕾期比连作高2.1倍,开花期比连作低18.0%。白羊草与隐子草在抽穗期的CPD高于开花期,但低于拔节期。
Compared to the ammonia loss of the continuous cropping plot during its budding stage , that of the rotation plot in the same growth period is 2.1 times higher , while during the blooming stage , the ammonia loss of the latter is 18.0 % less than the former .

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

组成白羊草草地的牧草种类较多,有22科74种牧草,且种的饱和度大,平均每平方米有26种牧草;
The kinds of forages on the Old World bluestem rangelands were 22 families , 74 species . There were 26 species in per meter square and the species saturation was large .

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。
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 .

从白羊草群落牧草的返青到枯萎,不同时期均有不同牧草可供放牧利用,但以8月份为最佳利用时期。
Though there were different plants , which could be grazed by beasts in different stages from return green to wither of old world bluestem Shrub Grassland , it is most suitable for grazing in August .
