菜用大豆稀植技术研究

研究了稀植条件下不同密度对菜用大豆农艺性状、干物质积累、叶面积指数、品质等的变化规律.结果表明:随密度的增加,株高增加,茎粗、节间数、分枝数、分枝总长降低;单株干物质最大积累量呈减小趋势、单株荚数、单株粒数、单株粒重降低,而百粒重、品质与密度关系不显著.以低密度处理21×104株/hm2的产量最高,为15 523.05 kg/hm2.

Effect of Density on the Agronomic Character and Yield of Vegetable Soybean

This experiment studied the variety of the agronomic character,dry matter accumulation,LAI and quality different densities of vegetable soybean.The study result showed that the plant height was increased with density increasing,stem thick,nodes,the branch number,the length of branch decreasing;pots plant,seeds plant,seeds weight plant was decreased with the density decreasing,the max accumulation of dry matter was decreasing.The relation of 100 seeds weight and quality wasn't significant with plant density.The yield of 21×10~4/hm~2 was the highest,yield was 15 523.05 kg/hm~2.
