有关土壤研究的论文摘要

The soil grade composition is affecting the soil physics and chemistry nature, this article is uses the hydrometer method becomes the soil to southwest area several kind of crags (purple ochre, calcareous soil, volcanic ash soil) the grade to carry on the determination Draws the following conclusion: ⑴The southwest area crag becomes the earth, purple ochre, the calcareous soil and volcanic ash soil's pellet sand grains account for the proportion to be big, the clay, the silt account for the proportion to be ⑵Between identical soil different soil layer, as a result of function and so on leaching deposition influences, on the soil lower level grade composition existence certain difference, rendzina's sand grains and the clay content increases along with the depth But volcanic ash soil's sand grains and the clay content increase along with the depth ⑶Because the different place identical soil the weathering, the leaching function and human activity's influence is different, soil separates composition existence certain ⑷Different soil identical soil layer, because becomes the earth the rock to be different, sandstone growth soil sandy many, the limestone, the mudstone growth's rock clay are ⑸The identical soil type different subgroup's soil, the granulometric composition is also different, but the general trend is

At noon tomorrow to translate ~ translated additional 50 thank you ~ ~Soil grain grade composition of soil physical and chemical properties of influence, this is the method of using BiChongJi southwest area into several rock soil (purple soil, lime soil, volcanic dust) grain Some conclusions:Southwest area into rock (soil, lime, purple soil and volcanic dust particles in the sand, which accounts for more than viscous grain powder, small 2 the same soil layer, due to the different leaching deposition etc, on the effect of soil layer of grain composition class there are differences of sand soil, black limestone and clay content with the increase of depth and And the sand and volcanic ashes viscous grain content decreased with 3 the soil due to different locations eluviation weathering, the influence of human activity and the degree of different level, the soil grain composition there is some 4 different soil layer, due to the different soil of rock, soil contains sand development of sandstone and mudstone limestone, development of viscous grain 5 the same soil types, different sub-types of soil particle composition is different, but the trend is Keywords: rock into the soil, The soil profile, Grain grade, Determination必须选我的哈～ 加油！ 挺你啊～BY：静
