aboveground造句

• To assess the medicinal value of cultural anisodus tanguticus , the contents of four bioactive tropane alkaloids , anisodine , anisodamine , scopolamine and atropine , in cultural and wild materials were determined by the hplc method . the results showed that content of each alkaloid in the aboveground parts of cultural and wild samples was lower than that in roots , and this explained why it was not the whole plant but the root that was used as medicinal materials . the content of each alkaloid in the roots of one - year cultural material was lower than that in the two - year plants . the discrepancy of the total of four alkaloids between one - year and wild plants is not significant . moreover , the total of four alkaloids , and the contents of anisodine , scopolamine , and atropine in two - year plants were higher than those in wild plant . thus there is medicinal value in the cultivated a . tanguticus as well as wild a . tanguticus , especially in the two - year cultural a . tanguticus
  为了评估人工栽培山莨菪的药用价值,采用高效液相色谱技术对人工栽培和野生山莨菪的地上部分和根中具有生物活性的4种托烷类生物碱:樟柳碱、山莨菪碱、东莨菪碱和阿托品的含量进行了测定.结果表明无论是人工栽培还是野生植物,地上部分中4种生物碱含量均远低于根,这解释了人们为什么用山莨菪的根而不是整株入药.在栽培植物的根中,一年生山莨菪中各生物碱含量均小于二年生山莨菪,其根中4种生物碱总量与野生根相比差异不是很明显;二年生山莨菪根中, 4种生物碱总量以及樟柳碱、东莨菪碱和阿托品含量均比野生的高.这说明人工栽培的山莨菪,尤其是二年生山莨菪,同野生山莨菪一样具有一定的药用价值
• The study investigated aboveground growths of caragana korshinskii and artemisia ordosica planted in four modes , revealing that in different planting modes their densities , heights and canopy width and biomasses remained unchanged or tended to decrease slightly ; the young shoots of a . ordosica annually grew in a s - shaped cure and the young shoots of c . korshinskii grew fast in spring and grew slowly or cease to grow from july on ; the biomasses and leaf area indexes of c . korshinskii and a . ordosica annually varied in a double peak curve and there were 8 annual plants that invaded in the four planting modes and formed higher coverage ; the quadrat with only a . ordoska appeared to have obviously lower coverage and biomass that the other three quadrats
  摘要对腾格里沙漠东南缘2种人工植被柠条和油篙在4种配置方式下地上部分的生长动态进行了研究，结果表明：不同配置方式下它们的密度、高度、冠幅和生物量基本不变或略微呈下降趋势；油篙新梢的年生长动态呈s型曲线，柠条新梢春季生长速度较快， 7月份以后生长速度缓慢或基本停止生长；柠条、油篙地上生物量和叶面积指数的年变化均表现为双峰型， 4种配置方式下共有8种1年生植物人侵，并具有较高的植被盖度；同其它3个样地相比，纯油篙样地1年生植物的密度、盖度和生物量明显偏低。
• The quantity of increased leaf efficiency contributed to the aboveground biomass gain after defoliated are different at different irradiance . at the initial stage , the increased leaf efficiency of defoliated plants contributed more to biomass increment of aboveground under higher light level than those under lower irradiance . as the treatment time extended , the contribution to growth of increased leaf efficiency of plants under intermediate light level went beyond those under full irradiancy
  ( 2 )叶受损的植株叶效率显著高于未受损植株；光照强度越高，植株的叶效率越高；受损植株增加的叶效率在不同光照条件下对生长的贡献大小不同，处理初期，全光照下叶损失植株增加叶效率对地上部分的生物量增加贡献大于中度光照，大于低光照下植株，随处理时间的延长，中度光照下的植株增加叶效率对生长的贡献逐渐超过了全光照下植株。
• Article 17 surveying and mapping of the estate boundary location lines of lands , buildings , structures and other aboveground objects attached to the land shall be conducted in accordance with the estate boundary location points and estate boundary location lines determined by the local people ' s governments at or above the county level or by relevant registration data and attached maps provided by such governments

• In contrast , plants from three populations of e . splendens showed high cu tolerance and substantial cu accumulation , under 100 umol l - 1 the plant of tl / zj / jd can accumulate 143 . 5 , 71 . 9 and 58 . 1 mg kg - 1 cu in the aboveground parts , respectively . the cu concentration in shoots was 16 to 27 times more than cu concentration in roots
  在盆栽试验条件下，海州香薷和紫花香薷对土壤铜、锌、铅复合污染都具有很强的耐性，地上部分铜、锌、铅等重金属含量在植物生长期呈现动态变化，但植物地上部重金属积累量保持增加趋势。
• Many researches have been conducted in terms of vertical variation of hydrological fluxes from canopy layer aboveground to root layer underground , and what were compared between forest and non - forest land , between different forest types , and even between different parts of the same crown
  国内外对于森林植被对水文通量的空间分布的影响，在垂直方向上分层次进行水文通量变化过程的研究；在水平方向上按照林地与非林地的对比，森林植被类型之间的对比，甚至同一树冠的不同部位的对比等，进行了细致的研究。
• The community productivity , structure and succession are significantly influenced by global climate changes . this study focused on soil respiration rate of stipa baicalensis grassland by using dynamic infrared gas absorbed method . we analyzed diurnal pattern of soil respiration rate and the influences of surface soil temperature and water content for this parameter , then compared the differences between day and night soil respiration rates , and explored the correlations between aboveground and underground biomass with the soil respiration
  温带的半干旱、半湿润区草甸草原属于过渡气候影响下形成的植被类型，对环境气候条件变化十分敏感，为了揭示半干旱、半湿润区草甸草原生态系统土壤碳素释放规律及其对主要环境因子的响应，本研究采用动态室红外气体吸收法测定松嫩草甸草原典型群落? ?贝加尔针茅群落土壤呼吸速率，分析了土壤呼吸速率日变化规律及表层土壤温度和含水量对土壤呼吸速率日变化的影响，比较了土壤呼吸速率的昼夜差异，探讨了地上生物量和地下生物量与土壤呼吸速率之间的相关关系。
