| 10. | ( 3 ) based on the experiments data , it has been found that if the emitter discharge of sdi was little , the depth of pipe buried should be shallow , and the distance between two micro holes should be chosen to equal or close the distance between two lateral pipes , if the emitter discharge of sdi was great , the pipe may be buried deeper , and the distance between two micro holes could be greater than the distance between two lateral pipes 根据一维土柱近似的湿润轮廓线初步选定了工程设计参数。在地下滴灌灌水器出流量较小情况下,埋深应浅,孔距应选择和毛管间距相等或接近;出流量大时,埋深可深,孔距大于毛管间距仍可获得较均匀的土壤水分分布。 |
