The lysimeter was adopted to investigate growth, yield and water use efficiency of corn on aquic brown soil in Shenyang under different treatments of controlled alternate irrigation.

在沈阳地区潮棕壤土上，采用蒸渗仪对不同控制性交替灌溉处理下玉米生长发育、产量和水分生产效率进行分析。

This showed that capacity of water-holding in biological soil crusts were obvious improve,and effected precipitation permeate or water second distribute process.The study results of"fertile islands"formation mechanism in biological crusts showed that biological crusts layer cover could increased nutrients content for below sand soil through precipitation permeate washing,and it promoted plants assimilate more nutriment.The matter import ways of biological soil crusts fertility island had many ways,including the effection of living macrobiotics metabolism in crusts levels,wind-sand flow of near surface,dust deposition and plants decomposition course,etc.Source of particle matter in biological soil crusts was wind-sand flow of near surface,and not dust deposition.Biological crusts layer cover had preserved effection for nature water content in 0-5cm soil layer,compared with the sand of no biological crusts layer,effecting precipitation permeate,and could not obvious restrained from the water evaporate process indoor experiment.

生物结皮层肥岛形成机制的研究结果表明：生物结皮层覆盖能够通过降水淋溶作用而增加下层土壤养分的含量，进而促进植物对养分的吸收；生物结皮层养分输入有结皮生物代谢、降尘、风沙流和植物分解矿化作用等多(来源：A73e3B3eC论文网www.abclunwen.com)种途径，但生物结皮层的颗粒物质来源主要是近地表风沙流，而不是大气降尘；生物结皮层覆盖对0-5cm土层自然含水量有一定的保护作用，并影响降水向深层渗透，不能有效的阻止表层水分的蒸发进程；研究表明采取人工促进技术能够在流动沙丘上形成生物结皮层，实现流动沙地的快速治理。

By the reason of the balance between water and air, the porosity property seems to be the most important parameter of substrate quality among these characters. This article tried out the results which the 5 different granule sizes vermiculite affect on the physical characters, water constants and maidenhair.

本试验研究了5种不同颗粒粒径的蛭石对其物理性质、水分常数和孔雀草苗期生长的影响，结果表明，基质总孔隙度在70%～90%，大小孔隙比在1：2左右时均能满足作物苗期生长的要求。

Commonly,office with air-condition lacks of natural airiness,people breathe out CO2,the fog that is coursed by smoking,some office equipment.These things emante maleficence to bulk in the office.There are wet resorting in the air-condition system,this becomes the "dirt-hiding place".Computers,displays,hand-holding telephone and other electric equipments can produce certain amount of ionization radialization.Some building materials also release certain injurant.

带空调的办公室一般缺乏自然通风，人们呼出的二氧化碳、吸烟产生的烟雾、某些办公设备散发的有害气体积聚其中；空调系统里有水分滞留，成为某些细菌、霉菌病毒的"藏污纳垢"之地；电脑、显示器、手持电话及其他电子设备均产生一定剂量的电离辐射；有的建筑材料本身也释放某些有害物质。

The research revealed the relation between the phosphorylation and dephosphorylation of MAPK and the activity of antioxidative enzymes in Malus under water stress.
