嫩江县是黑龙江省粮食的主产区和国家重要的商品粮生产基地,粮食总产量约19亿斤,是全国粮食生产先进县。这次耕地地力调查及质量评价结果显示,嫩江县中低产田土壤还占有相当的比例,另外高产田土壤也有一定的潜力可挖,因此增产潜力十分巨大,若通过适当措施加以改良,消除或减轻土壤中障碍因素的影响,可使低产变中产,中产变高产,高产变稳产甚至更高产。如果按地力普遍提高一个等级(保守数字),每亩增产粮食50斤计
Nenjiang County is the main grain-producing area in Heilongjiang Province and an important commodity grain production base in the country. The total output of grain is about 1.9 billion kilograms, making it an advanced county in grain production throughout the country. The results of soil fertility survey and quality evaluation showed that there is a considerable proportion of middle and low yield soil in Nenjiang County. In addition, there is a certain potential for high yielding soils, so the yield potential is huge. If the measures are taken to improve, eliminate or reduce Obstacle factors in the soil, can make low-yielding, middle-yielding high-yielding, high-yielding, stable and even higher yield. If we generally raise one grade (conservative figure) by geotechnical force, increase the grain output by 50 pounds per mu
