摘　　要：为探究抛秧稻田稻株分布对水稻产量的影响,本文总结分析了抛秧稻高产栽培技术和作物分布对群体产量的影响。水稻抛秧高产栽培技术包括合理育秧、形成壮苗;选择带土秧苗抛栽,确保水稻立苗;抛栽时注意均匀播撒,以促进秧苗健壮生长,改善秧苗素质。作物分布对群体产量的影响方面,适宜的基本苗密度可促进水稻分蘖增强,有效穗数增多,从而提升群体产量;合理的种植均匀度有助于植株充分利用光照、水和土壤等资源,减小个体与群体的竞争,构建合理的群体动态,从而实现水稻高产。本文为抛秧稻高产栽培提供参考。To investigate the effect of rice plant distribution on yield in paddy fields with seedling throwing,the high yield cultivation techniques of seedling throwing rice and the influence of crop distribution on population yield were summarized and analyzed.The high yield cultivation techniques of rice seedling throwing include reasonable seedling cultivation and the formation of strong seedling;choosing soil bearing seedlings for throwing planting to ensure rice seedlings stand upright;paying attention to even sowing during planting to promote the robust growth of seedlings and improve their quality.In terms of the impact of crop distribution on population yield,an appropriate basic seedling density can enhance rice tillering,increase the number of effective panicles,and thus improve population yield.Reasonable planting uniformity can enable plants to fully utilize resources such as light,water,and soil,reduce competition between individuals and populations,construct reasonable population dynamics,and thus achieve high rice yields.This article provides a reference for high yield cultivation of seedling throwing rice.
