苜蓿第一次刈割的产量一般占全年产草量的40%～50%,以后随着刈割次数的增加产草量逐渐降低,因此第一茬产量的高低对全年的产草量起着决定性作用。现就提高苜蓿第一茬产量应采取的措施,总结如下: The yield of alfalfa first mowing generally accounts for 40% ~ 50% of the annual yield of grass. Afterwards, with the increase of mowing times, the yield of grass reduces gradually, so the yield of the first crop affects the yield of the whole year Play a decisive role. Now to increase the first crop of alfalfa should take measures to be summarized as follows:
