水稻盘育抛秧栽培具有省力、省工、省水、省种、省秧田且提高产量等优点。笔者从1993年开始,将此项技术结合生产实际,先后进行了育苗营养土配比、壮苗培育、抛栽密度、化学除草以及规范化栽培等项试验研究,总结出了“河南沿黄稻区水稻盘育抛秧栽培技术规范”。1997年在郑州市示范1666.7hm~2,平均产量达8265kg/hm~2,比常规种植田的7110kg/hm~2增产16%,每公顷省水、省种、省肥、省工和增产等共增收节支2325元,显示出了广阔的应用前景。
Rice cultivation and throwing cultivation with labor-saving, labor-saving, water-saving, provincial species, provincial seedling and increase yield and so on. The author from 1993, this technology combined with the actual production, has conducted nursery nutrition soil ratio, strong seedling cultivation, throwing planting density, chemical weeding and standardized cultivation of other pilot studies, summed up the “Henan along the Yellow River region Rice cultivation and throwing cultivation technical specifications. ” In 1997, it demonstrated 1666.7 hm ~ 2 in Zhengzhou, with an average output of 8,265 kg / hm ~ 2, an increase of 16% over 7110 kg / hm ~ 2 in conventional fields, saving water, saving species, A total of 2325 yuan in revenue growth, showing a broad application prospects.
