aboveground part

基本解釋

The underground rhizome of P. australis and the aboveground part of S. mariqueter were the main sites of existing carbon storage.
地下根莖為蘆葦現(xiàn)存碳儲量的主要場所，而地上部分是海三棱藨草碳儲量的主要場所。
Compared with the aboveground biomass, however, only limited studies concerned the underground part due to complexity of roots systems and difficulties in root biomass measurement.
隨著人們對生態(tài)系統(tǒng)物質(zhì)循環(huán)和能量流動(dòng)研究的進(jìn)一步深入，地下生物量的研究漸成生態(tài)學(xué)的研究熱點(diǎn)。
Staying the decrease of the polysaccharide content of underground part and the total flavonoids content of aboveground part, increased polysaccharide and total flavonoids content in harvest.
延緩地下部分多糖和地上部分總黃酮含量的降低，增加其收獲期多糖和總黃酮含量。

地上部分
In late growth season(September),the iron content in C. angustifolia,C. meyeriana,and C. lasiocarpa all presented a pyramid form,with the leaf iron content at the top of pyramid being 3.08%,4.42%,and 1.18% of the sod layer(20-30 cm)iron content at the bottom of pyramid,respectively;while in early growth season(May),the profile of iron content fitted Logistic model well(R2=1.000,0.9902,and 0.9954,respectively). In the whole growth season,the iron content in the underground part of test wetland plants decreased gradually,while that in aboveground part changed with species and organs.
結(jié)果表明:3種濕地植物各器官的鐵含量呈金字塔構(gòu)型,成熟期（9月）時(shí)位于金字塔尖的葉的鐵含量約為位于塔底的下草根層（地下2030cm）的3.08%、4.42%和1.18%;幼齡期（5月）的鐵含量垂直剖面Logistic擬合很好,R2分別達(dá)1.0000、0.9902和0.9954;整個(gè)生長季地下部分鐵含量均逐漸降低,而地上部分具有種間和器官間差異。
