地下根

To understand the mechanisms of how plants affect soil biota from a plant physiological perspective, litter exclusion, girdling and root trenching experiments were carried out to investigate the impacts of above/belowground resource inputs on soil nematode communities.

本论文研究了云南哀牢山人为干扰条件下和植物群落自然演替过程中植物群落变化对土壤线虫群落的影响，并通过去凋、环割和切根三种方法分别控制植物的地上地下资源输入，从植物生理机制的角度分析植物对土壤线虫群落的影响机制。

Let him not grow up only to know about, let him grow up also to be. Let it not be only his possessions that grow, let him grow too! Let not only his exterior expand, let his interiority also have a depth, just as the trees rise up in the sky but their roots go deep underground.

Summary: A kind of irrigator applying to arbors in city virescence belts was studied, which has a great capacity and has no effect on scenery because it was buried round the roots of trees. It also has a lot of characters such as the filtration of water resource is undemanding, the seepage of water completely depends on gravity, the working stress of transporting water is low and so on..

本文研究了一种应用于城市绿化带乔木的地下渗灌装置，它具有容量大，埋设于树木根区土壤中不影响地面景观，对水源过滤要求低，完全依靠重力渗灌，输水工作压力低等特点。

In the 50 cm plough layer per m2 area, the total rootstalk weight of L.

结果表明：赖草株高45~120 cm，单生或丛生，具下伸土壤30~50 cm耕层间有横走根群，每平方米内，深50 cm耕层内赖草根茎总重量为1129.3 g，根茎总长度为2783.3 cm，根茎上的新芽589.7个，使土壤严重缺水，肥力下降；土壤水分在13.4%左右时，对出苗影响不大，对生长发育有很大的影响；气温在-6~6℃，根茎萌发出土，高峰期为4月上旬，平均单株结种量为468.4粒；每平方米内有赖草120~160株时，大黄产量损失达15.8%~17.8%；田间每平方米内有赖草1株时，采用人工或机械深耕捡出地下根茎，减轻翌年危害来源。

Their roots would remain skin-deep in the surface;there is no need for them to strike deep into the earth.

他们的根也仍将只停留在土地的表层。因为，对于他们来说，根本没必要深入地下寻找水分。

As a result of all this technology, the German scientific effort was pushed forward by leaps and bounds, and was conducted at several underground research facilities at Reinickendorf, Kummersdorf and Thuringia.
