近年来,黑龙江省嫩江县甜菜含糖率有逐年上升的趋势,1988、1989、1990与1991年甜菜含糖率分别为16.8％、17.6％、18.0％与18.6％,特别是1991年在全省含糖率普遍较低的情况下,含糖率较高,分析其主要原因是本区自然地理条件与推广良好的甜菜栽培技术。嫩江县可耕地大多数为黑钙土,黑土层深20～27cm,0～27cm土层内有机质含量4.1％,全氮0.35％,速效氮233ppm,全磷0.22％,速效磷(P_2O_5)41ppm,pH In recent years, the sugar beet rate of beet in Nenjiang County, Heilongjiang Province has been increasing year by year. The sugar beet rates in 1988, 1989, 1990 and 1991 were 16.8%, 17.6%, 18.0% and 18.6% respectively, especially in the province Sugar content is generally lower, sugar content is higher, the main reason for the analysis of the natural geographical conditions in the region and the promotion of good beet cultivation techniques. Most of the arable land in Nenjiang County is chernozem. The depth of black soil is 20-27cm, the content of organic matter in 0-27cm soil layer is 4.1%, the total nitrogen is 0.35%, the available nitrogen is 233ppm, the total phosphorus is 0.22%, the available phosphorus is 41ppm, pH
