摘要: 从满足夏玉米生育要求出发,采用麦秸还田,底施氮化肥、精量机播和化学除草等现代化综合技术,不但能促进壮苗早发和早熟高产,而且省工省力,降低成本,提高效率和培肥地力.采用这套简化栽培技术,平均每亩可增产粮食52.2公斤,少用工1.37个,节约开支8.54元,增加纯收益21.91元,耕层土壤有机质每年提高0.029%,土壤物理结构和营养供应性能也有明显提高.4年累计在京郊推广近百万亩,有力地促进了土地适度规模经营的发展.

Abstract: The simplified cultivation system for summer corn was characterized by the comprehensive utilization of winter wheat straw, heavy nitrogen ferilizer spreading, precision sowing, chemical weed control and high-level mechanization. Compared to the conventional technology, this new system could hasten crop growth, increase grain yield, improve labour productivity and raise soil organic matter content by 20%, 50%, and 0.0294% respectively while decreasing the production cost by 20%. The physical str...
