| 摘 要： | 在不同滴头流量和灌水量条件下对 2种不同质地土壤中的滴灌水分分布进行试验研究 ,通过对土壤湿润峰运移的测定 ,分析最大横向、纵向湿润直径与滴头流量、灌水量的关系模型 ,从而确定滴灌设计的滴头间距、流量、灌水历时等参数。结果发现 :果园滴灌中 ,粉质粘土滴水流量以 5L/h为宜 ,灌水历时 6～ 8h,滴头间距为 90 cm左右 ;重粉质壤土滴水流量以 3L/h为宜 ,灌水历时 7～ 9h,滴头间距为 70 cm左右。 |

| Abstract: | Drip irrigation was carried out under the conditions of various flow and irrigation quantity in two kinds of soil.By measuring the shift of soil moist peak and the relation among drip irrigation flow,irrigation quantity and maximum moist diameter in the vertical and horizontal direction were established ,which can be expressed as D(H )=(a b q)Q c.The design parameters of drip irrigation,such as interval distance of dripper,flow and irrigation period were also determined in this paper.They were 90 cm,5 L/h and 6-8 h respectively in dust clay and were 70 cm,3 L/h and 7-9 h in heavy dust loam in orchard irrigation. |
| Keywords: | drip irrigation moist diameter moist depth design parameter |
