| 摘 要： | 基于低温区大棚滴灌系统设计、建设和管理的实践和研究,在揭示建设中所遇到的供水水源工程建设、灌溉水升温和灌溉水质保障等问题的基础上,研究提出了可行的解决方案。研究结果表明:敞口地下长方形升温水池升温快、成本低,风险小,应作为大棚升温设施的首选;采用更换棚顶保温材料、设置升温池封堵筛网和沉沙坑等综合措施保障滴灌系统的正常运行;温室大棚滴灌毛管布设间距取40cm更为适宜;温室大棚滴灌供水系统很有必要安装补水自动化控制系统和适当加大供水管网埋深。研究结果可为低温区温室大棚滴灌系统的设计、管理提供参考和技术支撑。

| Abstract: | Based on the practice and research about design,construction and management of the greenhouse drip irrigation system in low temperature regions,some existing problems concerning the water supply engineering construction,warming irrigation water and irrigation water quality protection etc are revealed,some feasible solutions are put forward.The results show that the opened underground rectangle warming pool is the first choice for the design of the warming facilities in the greenhouse,because of its fast warming,low cost,little management risk.The comprehensive measures that are replacing heat preservation materials on the greenhouse roof,installing sieve on the upside of warming basin and desilting basin in rectangle warming pools etc,should be used to make the drip irrigation system work normally.The capillary spacing of the greenhouse drip irrigation should be taken 40 cm appropriately.It is necessary to install the replenishing water automation control system,and increase the buried depth of the water supply pipe network in the water supply system of the greenhouse drip irrigation.The research results can provide a reference and technical support for the design and management of the greenhouse drip irrigation system in the low temperature region. |
