我场1队提取小穆棱河河水灌溉稻田,因为流量小,用传统灌溉方法满足不了稻田用水。另一方面,灌区排水不畅,排水出路紊乱,使稻田北侧旱田作物和部分林地受到水淹的威胁,如1990年年降水只有440毫米,属于降水偏少年份,而大豆地就受淹3公顷多;另外,稻田北侧还有未开垦的低洼地,明水连片,水深一般在30～40厘米,最深达90厘米左右。为了发展水稻生产,充分利用水资源,我们曾设计了几个方案,几经比较,最后确 My field 1 team to extract small Muling River water irrigated rice fields, because the flow is small, with traditional irrigation methods can not meet the paddy water. On the other hand, the irrigated areas in the irrigation area are in poor drainage and the drainage outlets are in disorder. As a result, flooding of dryland crops and part of forest land on the north side of paddy fields is threatened. For example, the rainfall in 1990 was only 440 mm, Hectare and more; In addition, northern paddy field there are undeveloped low-lying land, Mingshui contiguous water depth is generally 30 to 40 cm, the deepest of about 90 cm. In order to develop rice production, make full use of water resources, we have designed several programs, after comparison, the final
