摘 要:本文就草原2号这种具有广泛生态适应性和稳定生产力的苜蓿品种的生长发育规律特点和肥力水平对其生长及产量形成,以及播期、播量和田间管理的增产效应等分别加以阐述,并在此基础上形成了渭北旱塬苜蓿规范化栽培技术体系,通过三年的生产实践,取得了明显的经济效益,有力地促进了旱塬农牧结合和土地用养结合,为振兴渭北农村经济开辟了一条新途径。This paper would deal with the experimental cultvar alfalfa—CY2 which has wide ecological adaptabilities and stable yields in the arid/ semiarid weibei highlands, Shanxi province. Here, we'd like to inform our tests concerning the patterns and characteristics of the growth and development of alfalfa—CY2, and the influence of the fertility level to the growth and formation of production of it as well as the seeding period, the seeding quantitY, the field management and the effect on the yield in— creass,and so on, respectively. Based on the above mentioned foundation, we set up our system of standardized model cultivation techniques for alfalfa—CY2. Through a three—year's productive practise,we have got remarkable economic profits from it. This system could promote the binding of crop farming with livestock raising,and the conbination of land utilization with soil conservation magnificently in weibei highlands. We look forward to seeing that it might open up a new way to develop the rural economy vigorously there.
