查询词典 fertile soil

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。

The purpose of the research was to obtain bacterial polyhydroxyalkanoic acids producers with good characters. With bottom sludge from Donghu Lake, bum soil from hillside, fertile vegetable soil and oil-soaked soil as initial samples, the bacterial strains with ability of synthesizing PHAs were screened not through enriching, isolation and purification, staining with Sudan black B and qualitative and quantitative analyses by infrared spectroscopy and gas chromatography. The results of staining with Sudan black B showed that there were 3 strains with ability of synthesizing PHAs among the 12 isolated strains and their numbers were Zj-5, Zj-8 and Zj-9 resp. All the 3 strains took on adsorption peaks at the points near 1741 cm^(-1) and the infrared spectrums of the strains Zj-8 and Zj-9 were similar.

［目的］获取性状优良的聚羟基烷酸合成菌［方法］以东湖底混、山坡裸地土、肥沃菜园土和油脂浸润土为初始样品，经富集、分离纯化、苏丹黑B染色、红外光谱及气相色谱定性定量分析筛选出具PHAs合成能力的细菌菌株［结果］苏丹黑B染色结果表明，在分离出的12株细菌中有3株细菌具有PHAs合成能力，其编号分别是Zj-5、Zj-8和Zj-9.3株细菌均在174cm^(-1)附近呈现吸收峰，菌株Zj-8和Zj-9的红外谱图相似。
