It shows that if the rainfall increased in the autumn , the storage of the soil water was higher next spring , moreover the better the soil moisture , and the earlier the regreening , and the higher herbage yield of the natural grassland 分析表明：秋季降水越多，环湖区土壤水分贮存量越多，翌年土壤墒情越好、牧草返青越早且牧草产量越高。
Abstract : based on the mechanism about herbage - squared - sand - obstacle for windbreak and sand - fixation , this paper propounded it ' s prognostication model , this model forecasted the sand - disaster of the daqi station on baoshen railway line 文摘:基于草方格沙障防风固沙机理，提出了沙害预测预报模型，该模型对包神铁路达旗车站沙害进行了预测预报
Meanwhile , their planting sites were also studied different herbages were found to differ in their soil water use intensities and depths and thus the proportions and site conditions for their mixed seeding were determined 同时对其立地条件进行了研究，结果表明不同牧草对立地土壤水分利用强度及空间分布有很大的差异，提出了不同牧草混播比例及立地范围。
They had been domesticated for five years and then the quality herbages 21 species ; 9 genera and 4 families of quality herbages capable of well adapting to the ecological conditions were screened 为退耕还林还草提供科技支撑，自1998年起从国内外陆续引进牧草品种4科、 14属、 36种100余份，经5年的适应性驯化，鉴选出了适宜该区生态条件的优质牧草4科9属21种。
Some management countermeasures are proposed : constructing new water conservancy projects and improving old irrigation works , intensifying the utilization process of surface rainfall sources , and establishing water - saving cropping - forestry - herbage compound ecological sys tem 提出了农业水资源管理的主要对策：一是强化地表雨水的资源化过程；二是加强农田水利设施的建设以及建立节水型的农林复合生态系统。
In silence they landed , and pushed through the blossom and scented herbage and undergrowth that led up to the level ground , till they stood on a little lawn of a marvellous green , set round with nature ' s own orchard - trees ? crab - apple , wild cherry , and sloe 他们悄悄上了岸，穿过花丛，芳香的野草和灌木林，踏上平地，来到一片绿油油的小草坪，草坪四周，环绕着大自然自己的果园? ?沙果树、野樱桃树、野刺李树。
Five minutes elapsed , during which franz saw the shepherd going along a narrow path that led over the irregular and broken surface of the campagna ; and finally he disappeared in the midst of the tall red herbage , which seemed like the bristling mane of an enormous lion 五分钟过去了，弗兰兹眼看着那个牧羊人顺着一条小径在罗马平原高低不平的地面上向前走，在长长的红色的牧草中消失了，那些牧草就象一只大狮子背颈上竖起的长毛。
She rushed excitedly into the field they were about to cross , and flinging herself flat on her back upon the grass , began to wipe her gown as well as she could by spinning horizontally on the herbage and dragging herself over it upon her elbows 她心里激动，就急急忙忙地冲进他们要经过的那块地里，仰面朝天地躺下来，开始在草地上平着旋转，用劲擦她衣服背后的糖浆，她还用胳膊肘把自己从草地上拖过去，又用这种办法把衣服擦了一遍。
2 . the determination of temperature and humidity on beijing highway greenbelt was made . the results along with other ecological benefits show the gradation of greening patterns which can exert best ecological benefits : arbor with shrub and herbage > shrub with herbage > vine > herbage 根据对北京高速公路不同植被的温、湿度的测定结果，结合其它生态效益的综合作用表明：高速公路绿地能够发挥最大生态效益的绿化模式顺序是乔灌草灌草藤本草本。
