摘要:
在净作和“玉/豆”套作条件下，研究钼肥拌种对大豆光合特性及产量的影响。结果表明：净作条件下大豆叶片的叶绿素Chl（a+b）含量、单株有效荚数、荚粒数、百粒重及产量均显著低于套作，而Chl a/b值、净光合速率和蒸腾速率则高于套作；钼肥拌种提高了大豆叶片Chl（a+b）含量、Chl a/b值、净光合速率、气孔导度、胞间CO2浓度、蒸腾速率、有效荚数和产量。在净作条件下，上述指标均以2.0 g.kg-1处理最高，其次为1.0 g.kg-1，其中2.0 g.kg-1处理植株叶片的净光合速率、单株有效荚数及产量分别较对照高36.14%、27.32%和37.25%。套作条件下，上述光合指标均以1.0 g.kg-1处理最高，其次为2.0 g.kg-1，其中1.0 g.kg-1处理植株叶片的净光合速率、单株有效荚数及产量分别较对照高34.46%、68.00%和84.85%。可见，钼肥拌种可提高大豆的光合特性及产量，套作模式中钼肥对大豆产量的贡献大于净作，且套作模式中钼肥的最适拌种浓度低于净作。
Abstract:
The effect of seed treatment with molybdenum on soybean photosynthesis was studied under mono-cropping and relay strip intercropping system.The results showed that the Chl(a+b) content, pods per plant, seeds per pod, 100-seed weight, and seeds yield of mono-cropping soybean was lower than those of relay strip intercropping soybean. However, the value of Chl a/b, net photosynthetic rate (net photosynthetic rate, Pn) and transpiration rate (transpiration rate, Tr) of mono-cropping soybean was higher than that of relay strip intercropping soybean.The Chl(a+b) content, the value of Chl a/b, Pn, stomatal conductance (stomatal conductance, Gs), intercellular CO2concentration (intercellular CO2concentration, Ci), Tr pods per plant and yield were increased by molybdenum treatment.The above indexes were the highest with 2.0 g.kg-1molybdenum treatment, and Pn, pods per plant and yield were higher by 36.14%, 27.32% and 37.25% respectively as compared with the control under the mono-cropping system, followed by 1.0 g?kg-1treatment.Whereas, in the relay strip intercropping system, the above indexes were the highest with 1.0 g.kg-1 molybdenum treated the seeds, and Pn pods per plant and yield were higher by 34.46%, 68.00% and 84.85% respectively as compared with the control, followed by 2.0 g.kg-1treatment. In a word, seed treatment with molybdenum improved the photosynthetic characteristics and yield of soybean, the molybdenum contribution to soybean yield in the relay strip intercropping system was higher than that in the mono-cropping system, and the optimum concentration of molybdenum in the relay strip intercropping system was lower than that in the mono-cropping system
