宁夏地区水资源的特点是量少、难以利用,分配不均。位于宁夏中部的永宁县黄羊滩农场内的万亩葡萄园已经采用了滴灌控制灌溉,但其相应的控制系统自动化程度不高,不能对葡萄实现轮灌的精确控制。在黄羊滩农场原有的滴灌系统基础之上,本文就此问题设计了与之配套的滴灌自动控制系统,本系统主要根据黄羊滩葡萄园现有的滴灌系统,考虑到土壤条件、气候因素与灌水量之间的关系对灌溉控制技术以及系统的硬件设计进行了搭建和研究。通过滴灌自动控制系统的搭建设计,预计能够改善灌区土壤结构,保持了土壤养分和肥力,有效控制和减少土地沙化、盐碱化,节约了人力,提高作物对水肥的利用率。
Water resources in Ningxia are characterized by small quantity, difficult utilization and uneven distribution. Drip irrigation has been used to control 10,000 mu of vineyards in Huangyangtan Farm in Yongning County, central Ningxia. However, the corresponding control system is not highly automated and can not accurately control the rotations of grapes. Based on the original drip irrigation system of Huangyangtan farm, this paper designs a drip irrigation automatic control system for this problem. The system is mainly based on the existing drip irrigation system of Huangyangtan vineyard, taking into account soil conditions, climatic factors And irrigation volume of irrigation control technology and system hardware design and construction and research. Through the design and construction of drip irrigation automatic control system, it is expected to improve the soil structure in irrigated area, maintain the soil nutrient and fertility, effectively control and reduce the desertification and salinization of land, save manpower and improve the utilization of water and fertilizer.
