摘要
试验采用裂区设计研究了晋绿豆9号在不同密度和施氮水平下的产量及产量性状,同时对绿豆栽培密度和施氮水平的互作效应进行了分析。结果表明,随着种植密度的增加,单株荚数呈减少的趋势,单荚粒数呈先降低后增加趋势;随着氮肥施用量的增加,单株荚数和单荚粒数均呈先增加后降低的趋势;随着种植密度和施氮量的增加,绿豆产量均呈现先增加后降低的趋势;密度与施氮量对绿豆百粒质量的影响相对较小;密度与施氮量互作时,种植密度为15万株/hm^2、施氮量为150 kg/hm^2最适宜。
Split plot design was used to study the yield and yield characteristics of Jinlüdou 9 under different densities and nitrogen levels, and the interaction effects of mung bean cultivation density and nitrogen application level were analyzed. The results showed that the number of pods per plant decreased and the number of pods per pod decreased first and then increased as increase of the planting density. With the increase of nitrogen application rate, the number of pods per pod and pods per plant increased first and then decreased.The yield of mung bean increased first and then decreased with increase of planting density and nitrogen rate. At the same time, the influence of density and nitrogen rate on the quality of 100 grains of mung bean was relatively small. When the density and nitrogen rate interacted, the planting density was 150 000 plants/hm^2, and nitrogen rate was 150 kg/hm^2, which was the most suitable.
