Development trend and enlightenment of alfalfa production in Europe
Looking back on the development of alfalfa in Europe in recent 100 years(1926-2022),the cultivation area of alfalfa in Europe had experienced a process of expansion to reduction.The first 50 years(46 years,1926-1972)was the expansion period in Europe,which increased from 250.74hm2 to 578.80hm2,an increase by 1.31 times,and by 1972,the cultivation area of alfalfa in Europe reached the highest level in histo-ry.In the 50 years after 1972(1972-2022),the cultivation area of alfalfa showed a downward trend,by 2017,it was only 247.llhm2,which was close to that in 1926.However,the per unit yield of alfalfa increased year by year.For example,in France,it increased from 2.01 t·hm-2 in 1945 to 7.6 t·hm-2 in 1988 and 14.8 t·hm-2 in 2017,which might be the reason for the reduction of cultivation area in Europe.In addition,the current situa-tion of alfalfa production in Europe and the development status of alfalfa in major European alfalfa producing countries,such as Italy,France,Spain and Serbia,were deeply analyzed.We got valuable insights from the de-velopment of alfalfa in Europe.Alfalfa,as an ancient cultivated forage in Central Europe,it was emphasised on increasing yields perunit area and reducing planting scale,at the mean time,great attention was paid to seed production.
