摘要
2018年在山西省农业科学院谷子研究所试验田对谷子品种长生13进行了施肥量栽培试验,调查施肥量对谷子干物质量积累与分配的影响。结果表明,施肥量越大,谷子的千粒质量和产量越大;施肥量对幼苗期和拔节期的谷子植株干物质量影响不大,但从抽穗期开始各处理干物质量有明显的差别,抽穗期到完熟期均是施肥量越大的处理干物质量越大;各处理叶和叶鞘干物质量占比均是随生育期进程逐渐减小,而各处理的茎干物质量占比变化趋势均呈先增加后减少。
In 2018,the experiment was conducted in Institute of Millet,Shanxi Academy of Agricultural Sciences,to investigate the dry matter accumulation and distribution of millet variety Changsheng 13.The results showed that the greater the amount of fertilizer applied,the greater the 1000-grain quality and yield of millet.The amount of fertilizer application had little effect on the dry matter quality of millet plants at seedling stage and jointing stage.However,from heading stage,there was a significant difference in the dry matter quality,and from heading stage to maturity stage,the greater the amount of fertilizer,the greater the dry matter quality.The mass ratio of dry matter in leaf and leaf sheath in each treatment gradually decreased with development of growth period.The mass ratio of stem matter increased first and then decreased with development of growth period.
