一、土粪和粪肥的增产作用土粪与粪肥均有明显的增产培肥作用,但其肥效常因质量高低而各异,质量高的土粪或粪肥增产作用则大,反之亦然。田间试验结果(表1)表明,每亩施用质量较高的粪肥1000—4000斤,增 First, the role of soil manure and fertilizer production Increased production of soil manure and manure have obvious effects of fertilizing, but often due to high and low fertilizer efficiency varies, high-quality soil manure or manure stimulation effect is greater, and vice versa. Field test results (Table 1) show that the higher quality of manure applied per mu 1000-4000 pounds, by
