摘要
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。
The differentiation criterion, method for differentiation and eveluation, type and area distributed in stated farmes, the way for utilization and amelioration programme for middle-low yields crop-land on Heilongjiang state farms have been discussed in detail in this paper. The total area of the middle-low yield crop-land on nine state farm sub-bureays is about 21.53 million mu, accuunt for 74.58% of the total state farm crop-land. It should be ameliorated by suitable practice measure, the total investment will be about 150-200 millon yuan. The crop yield for these ameliorated land will be increased by 160-200 millon kg per year.
