葡萄滴灌系统中毛管及微管滴头的设计

本文就葡萄滴灌系统中毛管及微管滴头的布置与设计作了部分方案对比,作者在分析了各种方案的优劣后,建议在葡萄滴灌系统规划设计时,尽量采用较短毛管和变径毛管,一般毛管长度控制在60m到90m范围内。文中列出了毛管不同布置形式下田间设备投资及运行费用比较共24种方案,可供读者参考。

DESIGN OF LATERAL AND MICRO-PIPE EMITTERS IN DRIP IRRIGATION SYSTEM FOR GRAPES

This paper presents scheme-comparing for the layout of lateral and micro-pipe emitters in drip irrigation system for grapes. After making an analysis of the advantages and disadvantages for each scheme, the author proposes that shorter lateral and variable diameter lateral in drip irrigation system for grapes should be used, and that the length of lateral should be contrled ranging from 60 m to 90 m. This paper present a list of comparing 24 alternative schemes for different lay-out of laterals in the aspects of field equipment investment and operation cost.
