黑土是我国著名的肥沃土壤之一,主要分布在我国东北松辽平原的东部(即黑龙江和吉林两省的中部)地区。根据1959年土壤普查资料初步估计,两省的黑土面积约计1000万公顷左右。同时根据近年的荒地考察结果得知,在黑龙江省东部的三江平原和黑龙江省北部的黑河地区,还有不少没有开垦的
Black soil is one of the famous fertile soils in our country, and is mainly distributed in the eastern part of the Songliao Plain in northeastern China (the central part of the two provinces of Heilongjiang and Jilin). According to preliminary estimates of the 1959 soil census data, the area of black soil in the two provinces is estimated at about 10 million hectares. At the same time, according to the results of the study on the barren land in recent years, it is known that there are still many untreated areas in the Sanjiang Plain in the east of Heilongjiang Province and Heihe in the northern part of Heilongjiang Province
