Abstract: With Suntory alfalfa as control, seven alfalfa varieties （Huangguan, Adina, etc.） were used to make regional test. The hay yield, crude protein content and other indices were determined to find out the appropriate high-quality varieties for east regions of Helanshan Mountain. Combined with its own characteristics of alfalfa, better planting techniques were studied. And the occurrence of common pests in different periods after mowing alfalfa was studied, so as to provide guidance for the control of pests and guarantee the goal of high-quality and high-yield alfalfa production.
