我省低产田有多种类型,但主要低产原因是土壤浅瘦,缺乏足够的有效养分。据统计,在全省粮食产量未跨《纲要》的1400万亩低产田中,属于这一低产原因的将近1000万亩(包括浅脚沙质田、浅脚黄泥田、结粉田及部分粘土田等类型),占水田总面积的28％。有机肥特别是绿肥,对改造这些低产田和培肥地力有着特殊的作用。过去两禾两肥制在我省的推广,对广辟有机肥源,达到以田养田,提高土
There are many types of low-yielding fields in our province, but the main reason for low yielding is that the soil is light and thin, lacking sufficient effective nutrients. According to statistics, in the 14 million mu of low-yield fields where the province’s grain output does not cross the “Outline,” nearly 10 million mu (including shallow-legged sandy soil, shallow-footed yellow muddy soil, knotted ground and some clay fields Other types), accounting for 28% of the total paddy field. Organic fertilizers, especially green manures, have a special role in transforming these low-yielding fields and fertilizing land. The past two Wo two fat in the promotion of our province, to open up organic fertilizer sources, to field Tian Tian, raising soil
