摘要
试验表明，塑盘旱育秧机械抛栽具有劳动生产率、抛秧质量高和成本低的生产优势及出叶快、分蘖势强、穗多和成穗率较低的生育特点，秧苗冠根球比（地上苗体与地下根球重量比）是衡量机抛秧的主要指标，适宜机械抛秧的冠根球比为１∶１０～１５，并提出主攻成穗率为核心的机抛秧稻群体质量栽培技术。
Experiment shows that seeding rice of plastic dry raising mechinary tossing has superionity of production of high labour productivity, high quality of tossing cultivict and low cost, it still shows that seedling rice has growth feature of leaf and tiller growing fast, more ears and low percentage of tiller Rate of crown to ball root is assessed main target of machinary tossing seedling rice quality, suitable rate is 1∶10￣15 Cualtivict science and technology of mechinary tossing seedling rice population quality with core of raising percentage of tiller was put forward
