晚播麦主要是指寒露至霜降节(10月20号前后)播种的小麦,比普通栽培播期晚20天左右,这种晚播麦晚播不晚熟,高产了倒伏,据吴桥县1987—1988年度3500亩的试验示范,原产可达到400—450公斤/亩,是提高粮食单产增强农业后劲的一条新途径,使晚播麦高产稳产有两个方面的意义:一是小麦晚播延长了夏玉米的生长期,使夏玉米可种植增产潜力大的中晚种,如掖单4号、2号等,以充分利用高温多雨的夏秋有利季节,提高玉米单产(单产600—650公斤/亩),
Evening broadcast wheat mainly refers to the cold dew frost (October 20 before and after) sowing of wheat, sowing 20 days later than ordinary cultivation of late-sowing evening broadcast is not late, high yield lodging, according to Wuqiao County, Experimental demonstration of 3,500 acres in 1988, the original can reach 400-450 kg / mu, is to improve grain yield and enhance agricultural stamina, a new way to make late-sowing high and stable yield of wheat has two aspects: First, the extension of late sowing of wheat The growth of summer maize, summer maize can be planted with large yield potential of the late species, such as Yedan 4, 2, etc., in order to make full use of hot and humid favorable seasons summer and improve corn yield (yield 600-650 kg / mu),
