本试验用不同品种及不同栽培管理措施(播期、密度、种植形式、不同施肥量、不同肥料品种、不同浇水时间、次数、不同留种形式等),进行多年多点试验,证明品种及栽培管理措施对谷子结实均有明显影响,尤以栽培措施应用的当否是产生秕谷的主要原因。选用适合当地条件、生产力强、秕谷率低的品种,在亩留苗6万株的基础上,争时早播,科学施肥、浇水,采用以穗中部籽粒留种的形式,是防秕增粒的关键栽培技术。 In this experiment, multi-year and multi-point experiments were conducted with different varieties and different cultivation and management measures (sowing date, density, planting forms, different fertilizer rates, different fertilizer varieties, different watering times, times, Cultivation and management measures have a significant impact on millet robustness, especially the application of cultivation measures whether or not the main reason for producing millet Valley. Selection of suitable local conditions, strong productivity, low trough Valley species, in the Miao Miao Miao 60000, based on the early sowing, scientific fertilization, watering, the use of spike in the middle of the seeds in the form of seed is anti-tang Granulation of the key cultivation techniques.
