中文摘要根据110余个表层土壤样品硼、锰含量的测定结果和土壤缺乏硼、锰的临界值指标,探究了川西北草原土壤中硼、锰的有效性及其丰缺状况.结果表明,本区土壤中全硼全锰含量丰富分别达166.0ppm和736.6ppm,但有效硼和锰的含量仅分别为0.45ppm和5.11ppm,土壤缺乏硼和锰比较普遍.为该区推广施用硼、锰微肥提供了初步的科学依据. 
英文摘要Boron and manganese contents in 110 soil samples from grassland in the northwest of Sichuan province were investigated during past years. The data collected showed that even though the mean values of total contents of boron and manganese in soils are 166.0 ppm and 736.3 ppm respectively, which are higher than those found in soils from other regions of China, the average available soil boron and manganese, 0.45ppm and 5.11 ppm, in the area are below the critical deficiency limits. The availabilities of the soil boron and manganese are mainly influenced by soil type, soilpH andorganic content.
