黑河地区位于黑龙江省北部,境内黑土面积广阔,自然肥力甚高,是全省生产商品粮的重要基地。但由于该区地处高寒,气候冷湿,因而部分土壤耕性不良,冷浆板结,肥力不调,成为限制农业均衡增产的低产因素。据初步调查,本区这类低产土壤共有230万亩, The Heihe region is located in the northern part of Heilongjiang Province, with a vast area of ​​black soil and a high natural fertility. It is an important base for the production of grain in the province. However, due to the alpine region and the cold and wet climate, some of the soil is poorly tillage and the cold paddle is not fertile and has become a low-yielding factor limiting the balanced increase in agriculture. According to preliminary investigations, a total of 230 million mu of low-yield soils in this area,
