为了提高单位面积的产量,通过二年的调查研究,对黑龙江垦区中低产田的划分标准、评价和划分方法,中低产田类型、面积、分布、利用途径和改良规划进行了详尽讨论。在九个国营农场管理局耕地中,中低产田总面积为2153.57万亩,占总耕地面积的74.58%。对中低产田应按不同类型采取相应措施进行改良。总投资约需15—20亿元,年增收粮豆约16—20亿公斤。
In order to improve the yield per unit area, through two years of investigation and study, the criteria, evaluation and classification method, middle and low yield field type, area, distribution, utilization and improvement plan of medium and low yield land in Heilongjiang reclamation area were discussed in detail. Among the nine state-owned farms, a total area of 21.5377 million mu of middle and low-yield farmland was cultivated land, accounting for 74.58% of the total cultivated land.
