摘  要：
为了研究不同滴水量对苜蓿生长发育及产量的影响,试验以新牧4号紫花苜蓿为研究材料,在滴灌条件下设置全生育期总滴水量3 600 m3/hm~2(W1)、4 200 m3/hm~2(W2)、4 800 m3/hm~2(W3)、5 400 m3/hm~2(W4)4个处理,并测定株高、枝条数、分枝数、产草量等指标。结果表明:苜蓿第一茬草W3滴水量的枝条数最多,单株叶重最重,分枝数最多;苜蓿再生草不同滴水量之间株高差异不明显;第二、三茬草中分枝数最多为W3,W3的茎粗、单茎重、单株叶重均最大;第一茬苜蓿干草产量以W3最高,第二茬苜蓿干草产量W3居第二,第三茬苜蓿干草产量最高的是W3,从苜蓿全年的生物产量看,W3的产量最高,达到27 273.5 kg/hm~2,高于平均值3 543.6 kg/hm~2。说明W3滴水量为塔里木垦区苜蓿最佳滴水量。

摘  要：
To study the effects of different amounts of dripping water on the reproductive structure and yield of alfalfa,No. 4 Xinmu alfalfa was used as a research material. The four treatment of total amounts of dripping water in the whole growth period were set under the condition of drip irrigation,including 3 600 m3/hm~2( W1),4 200 m3/hm~2( W2),4 800 m3/hm~2( W3),and 5 400 m3/hm~2( W4). Furthermore,the plant height,number of vimen,number of branches,forage production and other indicators of alfalfa were determined. The results showed that the number of vimen in the first crop of alfalfa was the most with the dripping water amount of W3,while the leaf weight of single plant was the heaviest,and the number of branches was the most. There was no significant difference in plant height of regrowing alfalfa between different amounts of drip water. The number of branches of second and third stubbles of alfalfa was the most with the dripping water amount of W3,while the stem diameter,single stem weight,leaf weight of single plant were also the biggest. The hay yield of first stubble of alfalfa was highest with the dripping water amount of W3,and the hay yield of second stubble of alfalfa ranked second with the dripping water amount of W3,and the hay yield of third stubble was also the highest with the dripping water amount of W3. Seen from the biological yield of alfalfa from the year,the alfalfa yield with the dripping water amount of W3 was the highest,which reached 27 273. 5 kg/hm~2,and higher than the average of3 543. 6 kg/hm~2. The results indicate that the W3 is optimum dripping water amount in Tarim Reclamation Area.
