- Effects of Density and Sowing Amount on Photosynthetic Characteristics and Yield of Vegetable Soybean
- 摘要:
- 为探索福建省鲜食大豆种植适宜密度与播量，采用双因素裂区试验设计，分别设4个密度水平和4个播量水平，研究不同密度和播量配置对鲜食大豆光合特性和产量的影响。结果表明：随着播量的增加，净光合速率（Pn）为上升趋势，胞间CO2浓度（Ci）为下降趋势；蒸腾速率（Tr）、叶绿素相对含量（SPAD值）及除种植18万和21万株·hm-2处理外的气孔导度（Gs）、胞间CO2浓度与大气CO2浓度（Ca）比（Ci/Ca）呈先升后降趋势，蒸气压亏缺（VPD）呈先降后升趋势。同一播量下，随着密度的增大，Tr和Ci呈上升趋势。相同密度条件下随着播量增加，株高和底荚高度为上升趋势，而主茎节数表现为下降趋势，有效荚数呈逐渐下降趋势，除12万和15万株·hm-2处理外产量均呈先升后降趋势。18万株·hm-2和每穴2株组合鲜荚产量最佳，达11 290.32 kg·hm-2,比12万、15万和21万株·hm-2分别增产0.45%、5.71%和14.15%。综上所述，在福建省鲜食大豆种植以密度为18万株·hm-2和每穴2株的栽培模式最佳。
