This study is focused on fine root production and its contribution to the belowground C and N storage in forest ecosystem of the Changbai Mountain Reserve, Jilin Province of China.

本研究以我国东北长白山自然保护区内典型的森林生态系统为对象，对细根的生长和周转，及其对地下碳、氮贮量的贡献进行了系统的研究。

Root systems, especially fine roots, which link the above- and belowground ecosystem processes, have become one of the most concerned focuses in ecology research.

根系，尤其是细根，作为联系陆地生态系统地上与地下过程的的纽带，已成为生态学研究中最受关注的热点之一。

Along with forest succession, the percentage of C and N turnover through fine root to the root, soil and the belowground increases gradually and then decreases.

随着演替的进行，细根每年周转的碳、氮量在根系、土壤和林地地下的碳、氮贮量中所占比例为先增加后减小。

Rhizome 8--10 mm in diam., with long, underground stolons; sepals 10--15 mm, with few vein anastomoses

根状茎8 --10毫米直径，具长，地下匍匐茎；萼片10 --15毫米，具很少脉网结 5 A。

The results of saline water irrigation (1990~1995) showed that the yields of wheat, corn, cotton and grain increased 30% more than those of non-irrigated crops. In the condition of spring irrigation and concentrated rainfall, the soil desalinized in root zone, and the accumulated salt due to saline water irrigation can be leached; reasonab...

三坝浅层地下咸水灌溉试验( 1 990～ 1 995)的研究结果表明，利用 3.0～ 5.1 g/ l的咸水灌溉小麦、玉米、棉花和高粱，均比不灌的增产 30 %以上；在春季河灌和汛期集中降雨淋洗的条件下，作物根层土壤不积盐；实行咸淡水轮灌，增辟水源，改善水质，可获作物增产。

The more degree shaded treatments were, the more biomass was allocated to the below-ground parts, resulting in the less ratios between above-ground and below-ground biomass. Shaded treatments limited sexual reproductive ability of V. spinulosa, which has reproduced less of ramets and winter tubers under shaded conditions versus natural conditions. V. spinulosa adapted the change of light by means of refuging life-history strategy.

随着遮阳强度的增加，刺苦草的最大叶长、总葡匐茎长和总的叶面积减少，遮蔽强度越大，分配到地下的生物量越多，冠根比率越小；遮阳生境下的刺苦草的有性繁殖受限，无性繁殖形成的分株和冬芽也比自然状态少得多；刺苦草采用回避策略应对光照胁迫。

Truffles grow underground among the roots of oak, elm, chestnut, pine, and willow trees where they form a symbiotic relationship with their environment.

块菌生长在地下土层中，与橡树、榆树、栗树、松树及柳树的根以及它们所处的自然环境形成共生关系。

In Part Two of Chapter One, the samples of sporocarps, cultured mycelia, and root-tips collected in a 15×30 plot were studied using ITS-RFLP and ITS-sequencing.

我们应用ITS-RFLP和ITS序列比较的方法对地上子实体、地下菌根及分离培养的菌种进行了种类鉴定和分析。
