通过对相同生产条件的苜蓿草地按照不同的施肥水平进行施肥试验,结果表明,不施N肥不会影响苜蓿的正常生长,不施P肥、K肥苜蓿的生长会受到影响。所以,在苜蓿草地生产中,适时的施入P肥、K肥能够提高苜蓿草的产草量,增加苜蓿草地的单位面积产值。
Fertilization experiments were carried out on alfalfa grass with the same production conditions according to different fertilization levels. The results showed that no application of N fertilizer would not affect the normal growth of alfalfa, but no growth of alfalfa and no application of P fertilizer. Therefore, in the alfalfa grass production, the timely application of P fertilizer, K fertilizer can increase the alfalfa grass production, increase the unit area of alfalfa grassland output value.
