五、土壤中的硼 (一)土壤全硼 1.土壤全硼的含量吉林省土壤全硼的含量范围是在17.7—63.7ppm,平均为32.0ppm。(见表21)。我省东部山区的土壤以白浆土含量最高。其次是集安一带的棕壤。而分布面积较大的灰棕壤全硼含量较低。一般以发育在沉积岩母质上的土壤稍高。中部的黑土含量较高,黑钙土则为中下等水平。西部的淡黑钙土、栗钙土和风砂土含量都很低。以风砂土为最低。盐碱土含量很高。非地带性土壤中的水稻土含量较高。草甸土及洮儿河流域的冲积土含量较低。
Five boron in the soil (a) of the total boron in the soil 1. The content of total boron in soil The content of total boron in the soil of Jilin Province ranged from 17.7 to 63.7 ppm with an average of 32.0 ppm. (See table 21). The soil in the eastern mountainous areas of our province has the highest content of white clay. Followed by the security zone along the brown soil. The distribution area of the larger brown soil total boron content is lower. Soil generally developed slightly above sedimentary parent material. The middle of the high content of black soil, black soil is the middle and lower levels. West of the light black earth, chestnut soil and sand content is very low. Wind sand is the lowest. Saline and alkali content is high. Non-zonal soil has a high content of paddy soil. Alluvial soil in meadow soil and Taohe river basin is low.
