| 英文摘要 | In order to provide practical parameters for sprinkler irrigation system design on sloping land, the effect of terrain slope on water distribution, sprinkler throw radius and water application uniformity were analyzed for the Rainbird LF1200 sprinkler. The results show that, the water distribution curve is roughly "heart-shape" on slope, and the water has the trend of focusing on the upslope with the increase of the slope. Throw radius decreases for the upslope and increases for the downslope as the slope increases. For the convenience of sprinkler irrigation system design on sloping land, a formula for computing throw radius on sloping land was put forward by the theoretical derivation, and it was verified by the experimental data. The impact of sprinkler pressure and spacing on CU for sloping land is more significant than that for flat ground. Under the experimental condition, no significant change is found regarding the influence of terrain slope on water application uniformity at the confidence level of 95%. Taking irrigation quality and economy into account, the Rainbird LF1200 sprinkler should operate at the manufactures' recommended pressure, rather than low pressure, with sprinkler spacing from 8 mx8 m to 10 mx10 m below the slope of 0.15 in practice. |
