| 摘 要： | 以内蒙古毛乌素沙地紫花苜蓿为研究对象,研究了不同水肥对紫花苜蓿茎叶比、叶面积、产量及水分利用效率的影响。结果表明,当灌水量为4 800 m3/hm2时,茎叶比值最小;当灌水量为4 800 m3/hm2,施肥量为120kg/hm2时,紫花苜蓿的叶面积最大,为最佳水肥调配模式;灌水量为4 800m3/hm2,配施120kg/hm2复合肥效果最佳。

Couple Effect of Fertilizer and Water on Growth and Yield of Alfalfa at Maowusu Sandland |
| |
| Abstract: | The effects of different fertilizers and irrigation amounts on the leaf ratio,leaf area,yield and water use efficiency of the alfalfa were studied in Maowusu sandy land in Inner Mongolia.The results showed that: when the irrigation amount was 4 800 m3/hm2,stem-leaf ratio was the smallest.When the irrigation amount was 4 800 m3/hm2 and the compound fertilizer was 120 kg/hm2,the leaf area of the alfalfa was the largest,which was the best combination of water and fertilizer. |
