1 概况红兴隆垦区位于黑龙江省东部三江平原腹地,属湿地集中分布区,有12个大型国营农场座落本区,是我国商品粮基地重点建设区之一.区域总面积为8893km~2,其中现有耕地40万ha,耕地中有70%为中低产田,可垦荒地6.7万ha.区内地势低洼、坡降平缓,一般在1/5000～1/8000,微地形变化复杂.土壤多分布草甸土、沼泽土、白浆土等,其中草甸土占65%.土壤特点是黑土层厚,基础肥力高、土质粘重,渗透性差,持水性强,耕性不良.由于受松花江、乌苏里江水系影响、洪涝灾害频繁发生,仅1991年至1994年连续4年的洪涝灾害农业经济损失达13.1亿元.
1 Overview Hongxinglong reclamation area is located in the hinterland of Sanjiang Plain in the east of Heilongjiang Province, which is a wetland distribution area with 12 large state-owned farms located in this area, which is one of the key construction areas of China’s commodity grain base with a total area of 8893km ~ 2 There are 400000 ha of arable land, 70% of the arable land is middle and low yield farmland, which can cultivate wasteland of 67000 ha.The area is low-lying and gentle slope, generally 1/5000 ~ 1/8000, the micro-topography changes more complicated. Meadow soil, swamp soil, albic soil and so on, of which meadow soil accounts for 65% .The soil is characterized by thick black soil layer, high basic fertility, strong soil stickiness, poor permeability, strong water holding capacity and poor tillage.Since the Songhua River The impact of Wusuli River water system and frequent floods and disasters were only 1.31 billion yuan for the four years in succession from 1991 to 1994 for flood-damaged agricultural economy.
