一、产量结构667米2理论株数0.5万~0.6万株,收获穗数0.48万~0.55万穗,平均每穗粒数700~800粒,千粒重300克,单穗粒重210~240克,667米2产量1000千克。二、栽培技术1.选地整地①选地玉米是高产作物,根系发达,需肥量大。滴灌玉米对地势要求不高,但宜选择耕层深厚、
First, the yield structure 667 m 2 theoretical strains of 0.5 million to 0.6 million, the harvest spike number 4800 ~ 0.55 million spikelets, the average grain number per spike 700 ~ 800, 1000 grain weight 300 grams, grain weight per spike 210 to 240 grams, 667 Rice 2 production of 1000 kg. Second, the cultivation technology 1 site preparation ① selected corn is a high-yielding crops, developed root system, a large amount of fertilizer needed. Drip corn on the terrain less demanding, but should choose a deep plow,
