Diaspididae is one of important pests in agriculture, forestry and ornamental plants. It not only pierces and sucks plant sap, destroys plant green organizations, but also pollutes the plant of leaf and fruit surface, affects plant of photosynthesis, leads to the plant of deformities, wither and die when it occurred largely.

盾蚧Diaspididae是农林、观赏植物的重要害虫之一，它不仅刺吸植物汁液，破坏植物绿色组织，而且当它大量发生时常污染植物叶面和果实，影响植物的光合作用，导致植物畸形、枯萎、死亡。

You want to leave the soil nice and loose for the roots of the fly trap. When you start to transplant, you want to be very careful of the leaves of the plant. Gently taking the plant out of its pot…and you want to remove quite a bit of the soil from around the roots of the plant. Here we can see that the actual root ball of the Venus Fly Trap is extremely small. The roots are very shallow, and they really don't need a whole lot of space for their roots. Here is the rye zone of the plant, which is really the core of the Venus Fly Trap, this white fleshy part. So we are going to make a small hole for this fly trap, place it down in the soil and just bring the soil right around the plant. Nice and easy. You don't want to pack it down too hard. We are going to repeat this part process for each one of these plants.

我们将玻璃瓶倒入大约四分之一的介质，而您必须要确定不要倒入太多的介质，您要为小捕的根部维持良好又松弛的介质，当您开始移植时，您要小心的保持维护住小捕的叶子，优雅小心的将小捕从旧盆中拿出，并且移除掉一些围绕在根系外多余的土壤，从这里我们可以实际看到小捕根部的土球非常的小，这些根非常的短小，而且他们完全不需要太大的空间，这是小捕最核心的球茎部位，这白色的基部，接下来我们要为小捕挖一个小洞，安置小捕后把介质好好的盖在植株根部简单又容易，您不需要把他压的太紧，我们就依照这样的方式来移植每一颗小捕，在您移植完全部的小捕后，要记得给他们喷上优质的水喔！

7 Percent of rain water was kept in plant after 7 days. The change of plant water δD indicated the water use efficiency of plant was effected by micrometeorology factors. The rising of soil temperature prevented plant root absorbing soil water, and soil moisture content facilitated plant root absorbing soil water.

大雨（65.3mm）降水后，雨水能够更快地渗入植物的根系层，对干旱区植物的补水作用较强，植物能够及时利用大雨，而且雨水在植物体内保持的时间较长，7天后植物体内保持雨水的41.8-53.7％。

The result shows that the relationship of conopy density with living cover plant space expresses a negative correlation, age class expresses a positive correlation, age class expresses a positive correlation; the relationship of conopy density with the dead covering plant and general covering plant expresses a positive linear covrelation, age class expreses an indicial ...

研究结果表明，郁闭度与活地被物负荷量呈负线性相关关系，龄级与其呈正线性相关关系；故郁闭度与死地被物和总地被物负荷量呈正线性相关关系，龄级与其呈正线性相关关系；蓄积量与地被物的负荷量呈线性正相关关系，但相关性较小。

In different degree of saline and alkali conditions controlled in lab or under field, contents as followed were determined: the absorption, transportation and distribution of major cations Na~+, K~+, Ca~(2+and Mg~(2+) in indicator plant; organic solute, and antioxidase activities, including superoxide dismutase, catalase and peroxidase POD characteristics of individual, population and community of the plant. Responses of the indicator plant to environment from physiological to community aspects were systemically discussed in this document.(1 Vegetional characteristics and edaphic indicators including bare patch index, dry biomass, percent cover by perennial plants, growth indicators of Leymus chinensis, soil organic matter and pH were sensitive to saline-alkali grassland degeneration.
