白沙灌区始建于1954年,设计灌溉面积2.02万hm2。该灌区已运行多年,由于年久失修,灌区输水损失相当严重,渠系水利用系数仅为0.4左右;早在20世纪60、70年代,白沙灌区还是河南省的先进典型,1980年以来,由于市场经济影响,农业逐步被人们忽略,灌溉开始走下坡路,灌区很少放水浇地,大田农作物不是不旱,而主要是灌区工程老化失修,渠道渗漏跑水漏水严重,加大了灌溉成本;再一个原因是,受市场经济影响,农业的投入产出不成比例等,轻农思想逐步扩大蔓延,形成恶性循环。因此,白沙灌区近几年来抓住国家加大对农业的投入以及解决“三农”问题和拉动内需等有利时机;一直在着手搞《白沙灌区节水改造规划》,恢复原有工程面貌和灌溉面积,力争在3年内改造成各项设备齐全的、全面实现节水灌溉和科学灌溉的现代化灌区。 Baisha Irrigation District was founded in 1954, design irrigation area of ​​20,200 hm2. The irrigated area has been in operation for many years. As a result of disrepair, the water loss in the irrigated area is quite serious. The canal water use coefficient is only about 0.4. As early as the 60s and 70s of the 20th century, Baisha irrigated area was still an advanced typical of Henan Province. Since 1980, Due to the impact of the market economy, agriculture is gradually neglected. Irrigation began to decline. Irrigated areas rarely irrigated. The crops in the field are not undrived. The main reasons are: the project in the irrigated area is aged and disrepair, and the channel leakage runs into serious water leakage and increases the cost of irrigation Another reason is that, under the influence of the market economy, the input and output of agriculture is disproportionately reduced and the thinking of the light agricultural sector gradually spread and formed a vicious cycle. Therefore, in recent years, Baisha Irrigation District has seized the favorable opportunity of the state to increase its investment in agriculture and solve the “three rural issues” and stimulate domestic demand. It has been engaged in the “Baisha Irrigation District Water Conservation Improvement Plan” to restore the original project appearance And irrigated area, and strive to be transformed within 3 years into a fully-fledged, fully integrated irrigation system for irrigation and scientific irrigation of modern irrigation.
