随着农业生产的发展,肥料工作特别显得重要.几年来,自治区粮棉不断增产,与施肥面积的扩大,施肥量的提高有很大的关系.但现有的肥源,还远远不能保证全部农田实现高产稳产.自治区的肥料来源,主要是人、畜粪尿和大量肥土.前者数量不多;后者肥效有限,费工特大;化肥供应也还不能满足需要.因此,必须大力发展绿肥,扩种苜蓿,才能适应当前农业生产的新形势. With the development of agricultural production, fertilizer work is particularly important .In recent years, the continuous increase of output of grain and cotton in the autonomous region has a great relationship with the expansion of fertilization area and the increase of the amount of fertilizer application, but the existing fertilizer sources are far from guaranteed All the farmland to achieve high and stable yield.Autonomous regions of the source of fertilizer, mainly human, livestock excreta and a large number of fat soil.The former is small in number; the latter fertilizer efficiency is limited, extra-large work; fertilizer supply also can not meet the needs .Therefore, we must vigorously develop Green manure, expanding alfalfa, to adapt to the current situation of agricultural production.
