钾的释放 meaning in Chinese

potassium liberation
potassium release

The releasing capacity , rate and availability of nonexchangeable k in soils with rich illite were much higher than those in others with rich kaolinite or montmorillonite , so that the amounts of nonexchangeable and total k absorbed by ryegrass and dry biomass in the soils were higher than those in others
富含伊利石的土壤非交换性钾的释放量大，速率快，有效性高；黑麦草吸收该土壤的非交换性钾量及总吸钾量高，生物量大。
The averages of release capacity and rate , amounts of nonexchangeable and total k absorbed by ryegrass and dry biomass in kaolinitic and montmorillonitic soils were 46 . 96 、 45 . 50 、 41 . 65 、 43 . 90 and 67 . 52 of those in illitic soils
而富含高岭石或蒙脱石的土壤非交换性钾有效性明显较低；非交换性钾的释放量和速率、黑麦草吸收该土壤的非交换性钾量、总吸钾量及生物量的均值分别仅为富含伊利石土壤的46 . 96 % 、 45 . 50 % 、 41 . 65 % 、 43 . 90 %和67 . 52 % 。
