Abstract

As for the alfalfa(Medicago sativa)seed production,phosphorus fertilizer can accelerate the formation and growth of root and differentiation of flower bud,so it is useful to increase seed yield and resistance to drought and cold.Potassium can accelerate shoots' horizontal development,make seed bigger,and elevates seed yield.Meantime,it can increase the resistance of alfalfa to cold,drought,heat and disease.Micro-nutrients enhance the seed yield of alfalfa by increasing the proportion of seed production relted organs such as florets/shoot,pods/floret and seeds/pod etc.
