| 摘 要： | 采用称重式蒸渗仪法,在贵州省黔西南地区研究了不同修剪留茬高度对沟叶结缕草的水分利用效率和耗水系数的影响。结果表明:随着修剪留茬高度由3 cm增至不修剪,沟叶结缕草的耗水量由96.33 mm增至386.60 mm,水分利用效率8月份高于7月和9月,以留茬高度6cm的水分利用效率高达0.75 kg·mm-1·hm-2。因此对黔西南地区的7、8、9月的沟叶结缕草地区夏剪,留茬高度定在6 cm较为理想,既可以节水又能达到美观效果。

| Abstract: | Effect of cut heights on water use efficiency（WUE） and water consumption coefficient（WCC） of Z.matrella （L.）Merr.were studied in Qianxinan area of Guizhou province with large scale weighting-lysimeter.The results showed that the water consumption of alfalfa in this area inceased from 96.33 mm to 386.60 mm,the WUE based on biological and economic yield boost from 0 to 0.75 kg·mm-1·hm-2,as the cut weights improved from 0 to 6 cm.The August WUE was higher than July WUE and September WUE.The best cut height was 6 cm in summer.It could saved water use and embellish surrounding. |
