| 1. | The lithosphere is the soil mantle that wraps the core of the earth
岩石圈就是包裹在地核外的土壤表层。 |
| 2. | Shoot growth and zn uptake were significantly enhanced by zn application
在土壤表层水分充足时，施锌对植株增长效果较明显，有利于玉米利用土壤水分。 |
| 3. | And it is in spring that soil water content , soil organic matter and calcium and magnesium suffered more seriously damage from overgrazing
春季过度放牧对土壤表层的水分、有机质和钙、镁等元素造成的损失最为严重。 |
| 4. | A problem is coating the earth with cement or bitumen on a large scale that would change the horde structural of the microbe in soil particularly in the surface layer of soil
摘要提出用水泥以及沥青大规模地覆盖土壤对于土壤，特别是土壤表层的微生物种群结构将会造成改变的问题。 |
| 5. | This paper first reports the difference of soil algae community makeup , microorganism amount , and soil phosphate activity between leanness soils and richness soils
本篇论文首先进行了贫瘠土壤与肥沃土壤表层土中土壤藻类种群结构、微生物数量以及土壤中三种磷酸酶活性的对比研究。 |
| 6. | Because no tillage and minimum tillage reduce erosion and concentrate nutrients in the surface soil just below the residue cover , micronutrients generally are less often deficient than under conventional tillage
由于少耕和免耕减少了水土流失，同时把养分富集在植物残茬覆盖下的土壤表层，所以，与传统耕作制相比，少耕和免耕一般不易发生微量元素的缺乏。 |
| 7. | 4 ) soil nutrient of leguminosae also higher than non - vegetation soil ; while organic matter and available k increased , there was no significant change in total n ( it increased slightly ) ; available p and soil ph decreased
4 )豆科植物较无植被覆盖地，土壤养分朝着良性循环转变。土壤有机质、速效钾含量提高，全氮含量稍有增加，速效磷含量降低， ph值有所下降；这些变化主要发生在土壤表层。 |
| 8. | ( 3 ) the diurnal observation results of soil co2 dynamics in the field display the variation of soil co2 concentration and the releasing rate of co2 coming from soil surface is controlled by temperature . the correlation between co2 concentration in the top soil and temperature is very significant
( 3 )土壤co _ 2浓度和土壤释放量昼夜动态变化均受温度控制。土壤co _ 2浓度中义摘要变化与温度相关分析结果表明，土壤表层co 。浓度的变化与温度相关性显著。 |
| 9. | In this paper , on the basis of observed data , spatial - temporal variation characteristics of soil temperature and soil moisture . soil temperature effects on soil water movement are studied for several kinds of typical underlying surface by using statistics , spectrum , filtering wave methods
本文首先根据几种典型下垫面条件下的土壤表层( 1 - 1m )的土壤温湿度资料，采用统计分布、功率谱分析、滤波等方法分析典型下垫面条件下土壤表层水热分布特征及其相互作用。 |
| 10. | But variation of the co ; concentration in the bottom soil show that sink effect of carbonate rock on the soil air co2 ( 2 ) the diurnal observation results of soil co2 dynamics in the different vegetation show that the soil co2 concentration in the bare land is sensitive to environment , but the soil co ; concentration in the other experimental site , which covered with vegetation , restrain the variation
在土壤?大气界面上，土壤表层可为大气提供游离co _ 2 ；而土壤深部co _ 2浓度的变化则显示下覆碳酸盐岩对co _ 2有吸收作用。 ( 2 )在不同植被系统中，土壤co _ 2昼夜动态变化进程不同。观测资料表明：裸地对外界环境的变化相当敏感，而有植被覆盖的竹林和草甸对土壤co _ 2浓度动态变化有平抑作用。 |
