前言:1.本文是新西兰林肯学院农业工程研究所关于滴灌设计进行12个月学术考察研究,所写详细报告总结,可作为逐日作灌水设计的手册。2.灌溉需水量:滴灌系统的水力计算是根据灌溉需水量高峰 P·I·R,由下式得出:P·I·R(升/每日)=f_1f_2[GC+1/2(1-GC))×0.8EpanA……①式中:f_1某一作物的作物因素。f_2包括土壤渗漏损失在内的土壤因素。
Preface: 1. This paper is a 12-month academic investigation study of drip irrigation design conducted by Institute of Agricultural Engineering, Lincoln College, New Zealand. The detailed report is summarized and can be used as a daily manual for irrigation design. 2. Irrigation water requirement: The hydraulic calculation of the drip irrigation system is based on the peak irrigation water demand, P · I · R, as follows: P · I · R (L / daily) = f_1f_2 [GC + 1/2 -GC)) × 0.8EpanA ... ① Where: f_1 crop factors of a crop. f_2 Soil factors including soil seepage losses.
