吨粮田建设是一项保证农业高产稳产的综合性工程,从水利建设角度看,还存在一些值得重视的问题:第一,地址选择不合理.为了便于参观学习,各地往往把吨粮田选择在公路沿线,有的甚至规定在公路两侧100～200米范围内.结果,一是水系不独立,沟系不完整,防洪、排涝、降渍有问题;二是灌溉质量差,输水路线长,不适应吨粮田小苗移栽机插秧对浅湿灌溉的严格要求,一次开机灌水田亩少,全田灌完持续时间长,灌溉不及时,影响水稻生长,提高了灌溉成本.三是破坏原有沟渠,重新开沟筑渠,造成浪费.四是涉及的乡、村多,管理不便;特别是村级专业
The construction of the grain field is a comprehensive project to ensure the high and stable output of agriculture. From the perspective of water conservancy construction, there are some problems that deserve attention: First, the address selection is not reasonable. In order to facilitate the study tour, Some of the roads along the highway are even within the range of 100 to 200 meters on both sides of the road. As a result, one is that the water system is not independent, the system of the ditch is incomplete, and flood control, drainage and lowering have problems; secondly, poor irrigation quality and water conveyance routes Long, not suited to the grain seedling transplanting machine transplanting machine for the shallow wet irrigation strict requirements, a boot of irrigated fields less acres, the whole irrigation finished a long time, irrigation is not timely, affecting rice growth, increased irrigation costs. The original ditches, re-ditching the ditches, resulting in waste. Fourth, the township and village involved, and inconvenient management; especially the village-level professional
