available potassium meaning in English
有效态钾
Examples
- Determination of available potassium in forest soil
森林土壤速效钾的测定 - Within the range of 270m ~ 770m , macro - element ( total phosphate , total potassium , available potassium ) , trace elements , cec and soil ph were correlated in 50m with the rage of 780m
全氮的空间变异与间距无关，存在纯块金效应，块金值为0 . 2 ，对于全氮，采样间距应小于50m 。 - That of available potassium showed the interruption of human activities with the highest value ( 81 . 2 % ) , and of cec , total potassium , available copper showed that spatial auto - correlation was master with the value less than 25 % . there was no relationship between spatial variability and distance , but with the nugget of 0 . 2 , therefore , the distance
Kropng插值结果进一步表明土壤表层养分含量具有高度的空间异质性，决定了空间格局的存在，养分含量的斑块（ patch ）的大小、形状及空间分布等具有显著的差异，但是不论在什么方向，养分含量由低到高的分布梯度规律总是存在的。 - Vegetation restoration also resulted in the changes of soil physical and chemical properties , i . e . , the contents of organic matter , alkali - hydro nitrogen , rapidly - available potassium and the contents of fine sand , very fine sand and clay were increased significantly , while ph and the content of rapidly - available phosphorus were decreased
植被的恢复使土壤理化性质发生了变化，与恢复前相比土壤中有机质、碱解氮、速效钾以及细砂、极细砂、粉砂、粘粒含量显著增加， ph值和速效磷含量降低。 - 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。
