The results showed that: planting two crops in a year under the condition of 640 mm annual mean rainfall in the Loess Plateau conduced to the substantial use of solar and water resources in summer fallow, the biomass yield, economical yield and water use efficiency was improved in different degrees, and the material cycle was enhanced.

结果显示：在黄土高原东南部年降雨量达640 mm左右的旱作农田，发展&一年二熟&种植能较好地利用夏闲期的水热资源，不同程度地提高了全年的生物产量、经济产量、水分利用效率，加强了农田物质循环。

Using the observed data of spring-sowed two years fresh alfalfa growth condition and parallel climatic conditions,analysis is made of the alfalfa's growth height and the speed variation rule with time in the loess plateau area of East Gansu,and the correlation dependence of dry matter and the fresh grass with the activity accumulated temperature.
