Abstract

Abstract: In Chifeng region,the winter injury of alfalfa was classified into four kinds:(1)no injury,(2)the injured alfalfa regenerating new buds from roots,(3)no regenerating new buds from roots,(4)dead plant.The reason of winter injury was that the planting date was late and the roots before overwinter are weak and shallow.Therefore,the measures of early sowing in good time and shallow ploughing and covering soil before over winter could efficiently accelerate the growth of seedlings and reduce winter injury.

Key words: Alfalfa, Winter injury, Defensing technique
