养分富集 meaning in English
nutrient enrichment
nutrientenrichment
Examples
- 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。 - The available phosphorus contents of the run - off from the plot iii and plot iv were higher than that of other two plots " run - off . the nutriments of sediments from the four plots were higher than the nutriments of soil in the plots . the plot ii and plot iv had the higher enrichness degree of total nitrogen than the other two plots ; the available nitrogen enrichness of sediments from plot iv was the highest , that of from plot illwas the lowest ; the available phosphorus enrichness of sediments from plot iv was the highest , that of from plot illwas the lowest ; the available potassium enrichness of sediments from plot ivwas the highest , that of from plot ii was the lowest
泥沙各种养分含量均高于小区内耕作层土壤中的相应养分含量，表现为：第2 、 4小区的流失土壤全氮养分富集度高于其余两个小区；第4小区流失土壤有效氮富集度最高，第2小区次之，而第1小区和第3小区的流失土壤有效氮含量与区内耕层土壤相似；各小区流失土壤中速效磷富集度为第4小区最大，第3小区最小；而第4小区耕层土壤中在流失过程中速效钾西南农业大学二oo二届硕士学位论文一积累量最大。 - The function of desert microbiotic crusts in erdos was analyzed , the results ahowed that : microbiotic crusts consist of fine sand and thick powder sand , but differs with the wind - drift sand , wind - drift sand are coarse sand and fine sand ; microbiotic crusts influence the rainfall distribution again and effect on the evaporation of infiltration moisture ; microbiotic crusts has the power of water conservation and the function of enrichment of nutrients
摘要本文对鄂尔多斯沙漠生物结皮作用进行了初步研究，结果表明结皮层的机械组成以细沙和粗粉沙为主，而流沙以粗沙和细沙为主；生物结皮层影响降水的再分配作用，并影响入渗水的蒸发规律；生物结皮层县有较好的保水特性和养分富集作用。
