我区粮食产量低而不稳,原因很多。但与土地养用失调有密切关系。近年采用以油促粮、以豆养田、以草(包括绿肥)肥地和充分施用磷肥的办法,取得了较好效果。为使这些经验在全区发挥更大的作用,现根据不同自然区域提出以下意见。一、高原沟壑区:地势平坦,土层深厚,气候温和,雨量较多。作物以小麦为主,面积占播种面积的40～50％。土壤贫瘠,麦田施肥面积仅有一半左右,亩施厩肥2000～3000斤,小麦连作年限长,亩产不过百斤左右。 (1)人均耕地在3亩左右的社队,油菜面
There are many reasons for the low and unstable grain output in our region. However, it is closely related to the imbalance of land use. In recent years, the use of oil to promote grain to bean fields, to grass (including green manure) and the full use of phosphate fertilizer approach, and achieved good results. In order to make these experiences play a greater role in the region, the following opinions are based on different natural regions. First, the gully area of the plateau: flat terrain, deep soil, mild climate, rainfall. The main crop of wheat, sown area of 40 to 50% of the area. Barren soil, wheat field fertilization area is only about half, manure fertilizer 2000 ~ 3000 kg, wheat, even the long working years, but per kilogram per kilogram or so.
