| 摘 要： | 对紫花苜蓿品种西香和会宁不同刈次和不同深度土壤含水量测定结果表明,在不同刈次,引进种土壤含水量明显小于当地种;不同深度土壤含水量引进种西香明显小于当地品种会宁,且多数表现为高—低—高"V"字型变化。但在60～80cm,80～100cm土层,土壤含水量变化有所波动。这种规律性变化与引进种根系强大、有较强的生长势与生长量以及外界降水有关。引进种能吸收深层土壤的水分,且有较强的增产潜力和抗旱能力。 |

| Abstract: | Though measure the different harvest and soil depth to different alfalfa varieties,the result shows that Xixiang has obviously less soil water content than local variety Huining in different harvest and different depth. Most of them have a "V"change which is high-low-high.But soil depth in 60~80 cm and 80~100 cm,the change of soil water content is different. The soil water content of Xixiang isobviously affected by big and powerful root,big yield and rainfall.Xixiang can absorb water in more depth ,and it has big potentiality to increasing production and sharp ability of resistance drought. |
