【摘要】 合理灌水对果树的正常发育和生理过程有重要影响,它能保证果树成活率,促进果树萌芽,提高坐果率和果品质量。为了实现果树的科学灌溉,需要对灌溉工程进行精确的设计。结合山西省晋城市陵川县丈河村果园灌溉工程,通过RTK仪器进行地形测量与CAD软件进行绘图以及对关键数据进行分析计算,对采用涌泉灌溉的果园项目进行了管路布置、轮灌组划分、灌溉制度制定,得出在水源供水稳定充足的情况下,灌区灌水方式为小管出流灌溉,选用的主管管径为110mm,种植密度为600株·hm-2,每株灌水量为60L·h-1的灌区,环沟底部开挖宽度一般为10cm,轮灌组共分为14个,且1个轮灌组面积不宜超过1.13hm2的结论。此结论可作为类似灌溉工程设计的参考。更多还原

【Abstract】 Scientific irrigation plays an important role in growth and physiological and biochemical process of fruit trees, which also guarantee the high survival rate,promote fruit trees bud,and increase the production and fruit quality.The precise design of irrigation engineering is required for scientific irrigation.This study was conducted for the irrigation engineering in Zhanghe village in Lingchuan Shanxi.RTK instruments were applied to carry out the topographic survey.The drawing and data analysis were complemented by CAD software.In orchard with bubbler irrigation,small pipe flow irrigation was suggested after the pipeline layout,division of irrigation group,and determination of irrigation plan.The optimum diameter for main pipe was 110mm,with the planting density of 600plants per hectare.In irrigation area with 60L·h-1per plant,the ring groove excavation width was generally 10cm,and 14rotational irrigation groups with 1.13hectares each were suggested.The above findings provided valuable reference for the irrigation engineering design.更多还原
