1.The high average value of bush on alpine bush-land is 80.0cm, the bush coverage is 52.7%, the high average value of herbage is 5.4cm, the herbage coverage is 89%, and the biomass is 216.6g/m~2. The space structure of bush-band is obvious, which is divided into 3 layers such as the highest bush layer, low bush layer and herbage layer.
高寒灌丛草地灌丛层平均高度80.0cm,盖度52.7%,草本层平均高度5.4cm,盖度89%,植物量218.6g/m2。 灌丛草地植物群落层次分化明显,可分为高灌木层、低灌木层及草本层。
2.was1.51 kg/km2.a, while shrub and herbage vegetation were 0.54 kg/km2.a and 2.78 kg/km2.a, respectively. 2. The nutrition recycling velocity of arbor, shrub, herbage vegetation which beyond the surface
乔木的侵蚀泥沙年均磷素损失量为 1.51 kg/km2,灌木为 0.54 kg/km2,草本为 2.78 kg/km2。
3.This season is the best period to use herbage. Except May and June,the herbage and nutrient yield of northern slope are much higher than of the slopes in green season.
除五、六月外其它各月青草期牧草产量和营养物质产量,北坡均显著高于其它各坡向(P<0.05)。
4.In order to promoting the development of compression theory and compression rheology for agricultural fibrous materials, exploiting and utilizing fresh herbage product, the stress relaxation process of typical fresh Alfalfa, Sorghum Sudanese and Corn stalk has been tested and studied on the 9KG-350 high density baler according to the rheologic characteristic of fresh herbage materials in the process of the compression.
为进一步推进农业纤维物料压缩理论及压缩流变学的发展,促进新鲜草产品的开发和利用,本文针对新鲜草物料压缩过程中的流变特性,以实际生产设备9KG-350型液压式高密度压捆机为试验装置,以三种典型鲜物料(苜蓿、苏丹草、玉米秸秆)为试验对象,对其在高密度压捆过程中的应力松弛进行了测试研究。
5.According to the theory and method that plant is introduced and domensti-cated,191 varieties of herbage were recommended and collected from herbage of the locality、other parts of the country and abroad from 1984 to 1989.Salt tole-rance of each variety in light、medium、strong saltinized soil were identificated using fied experimental method,72 varieties that adapted to different level salt tolerance soil on the west bank of the Bohai have been sieved.
依据植物引种驯化的理论和方法,1984~1989年先后从国内外及当地引进、采集了191个牧草品补(22个科86个属); 采用田间直接鉴定法进行了轻、中、重二种盐化程度的耐盐鉴定,筛选出72个品种可洪渤海湾西岸滨海盐渍土区不同盐化土壤上选择种植;
6.In Summer, the content of Sulfur in edible herbage was more higher than that in Spring and Autumn. The content of Magnesium in herbage was lower than the standard from NRC(1985),but more higher than that around Qinghai Lake;
牧草中镁的含量不能达到NRC(1985)绵羊营养需要规定的标准,但高于青海湖地区牧草镁的平均含量;
7.Arbor has the largest emission factor of CO2, bush takes the second place, and herbage has the lowest emission factor.
乔木释放的CO2排放因子最大,灌木次之,草本最小。
8.narrow-leaved green herbage: grown as lawns; used as pasture for grazing animals; cut and dried as hay.
叶子细长的绿色牧草;用作草坪;用作牧场饲养动物;刈割后晒成干草。
9.STUDY ABOUT DOMESTICATION AND UTILIZATION OF WILD BEE ON HERBAGE SEED BR(?)EDING FARM OF RED CLOVER
红三叶草种籽场长木蜂的人工训育及利用研究
10.To feed on(herbage) in a field or on pastureland.
