密度与行距配置对春谷子农艺性状及产量的影响

Effects of Different Density and Row Spacing on Agronomic Traits and Yield of Spring Millet

为了探索春谷子的高产、高效种植方式,以长农35为材料,采用二因素完全随机试验的方法,对宽窄行与等行距栽培条件下春谷子不同栽培密度与产量的关系进行研究。结果表明,同一密度条件下,不同行距配置下春谷子株高、茎粗、穗长、穗粗、出谷率、千粒质量和穗数差异不显著,各处理间的单穗质量、单穗粒质量、倒伏率与产量存在显著差异;春谷子在4种密度条件下,宽窄行种植方式(20 cm+40 cm)较等行距种植(30 cm+30 cm)的产量分别提高0.59%,2.74%,4.01%和1.80%,在密度为3万株/hm2条件下产量达最高,为4 903.50 kg/hm2。

Taking Changnong 35 as test materials,the relationship of spring millet density and yield under wide-narrow row planting and same row space were studied by the method of two element resourceful test.The results showed that with the different spacing forms,there were no significant differences in plant height,stem diameter,ear length,ear diameter,grain percentage,1 000-grain quality and spike number of spring millet,the yield and spike quality,grains quality per spike and percentage of lodging had direct correlation under the same density.Under four densities condition,the yield of wide-narrow row planting(20 cm+40 cm) was significantly higher than the same rowspace(30 cm+30 cm),the yield increased 0.59%,2.74%,4.01%,1.80%,respectively,the yield of 30 000 plants/hm2 was the highest,which was 4 903.50 kg/hm2.
