草坪灌溉与排水课程设计的关键环节分析

摘要

In order to improve independence and creativity of college students majored in grassland science, the students were required to make curriculum design of sprinkler irrigation.The formulas in this curriculum de-sign are difficulty to be understood,mastered and remembered.It is hard for college students to find the begin-ning,and the proper formulas of calculate segments and connection between different segments of design.Key formulas (design irrigation quota,design irrigation cycle,sprinkler head selection and layout,irrigation group) and connection between different key segments of design were explained in this paper after summarizing experi-ences in teaching.This paper was used to guide college students in their curriculum design of sprinkler irriga-tion.The optimum design was used to meet turfgrass water requirement and water saving,form a good water scenery on trufgrass fields and resolve water resource scarcity in our country.%为了提高草业科学本科生创造性和独立性，要求学生完成喷灌系统课程设计。该课程设计特点是公式多、难记忆、抽象和难掌握。在课程设计过程中，学生经常找不到切入点，不知道各环节计算公式和各环节之间的联系。通过对多年教学过程的总结和概括，分析设计灌水定额和灌水周期、喷头布置和选型、轮灌组划分等关键环节，进一步阐明各关键环节之间的联系，以期指导学生更好掌握草坪灌溉与排水课程，达到满足草坪草用水、节约用水、形成水动景观效果、解决我国水资源紧张等目的。
