【目的】探讨罗汉果与生姜间作对生姜光合特性和产量的影响,为罗汉果间作生姜种植提供参考。【方法】2011年进行大田实验,设3个处理,分别为罗汉果棚式栽培间作生姜(P)、罗汉果立式栽培间作生姜(L)、裸地栽培生姜(CK),比较不同栽培方式对生姜光合特性和产量的影响。【结果】罗汉果棚式栽培间作生姜条件下,生姜叶片的净光合速率在生长前期略高于CK,生长后期低于CK,气孔导度、胞间CO2浓度和蒸腾速率均低于CK,产量与CK差异不大。在罗汉果立式栽培间作生姜条件下,生姜叶片的净光合速率在生长前期高于CK,生长后期略低于CK,气孔导度、胞间CO2浓度、蒸腾速率低于CK,产量比CK增加68.1%。【结论】罗汉果—生姜间作可以改变生姜叶片的净光合速率,影响生姜产量,减少投入,提高土地利用率,增加经济效益。
【Objective】 The objective of this study was to investigate the effects of interplanting ginger and Ginger on the photosynthetic characteristics and yield of Ginger, providing a reference for the cultivation of Giant Ginger. 【Method】 Field experiments were conducted in 2011 and three treatments were set up, including the cultivation of Ginger (P), the cultivation of Ginger (L) in vertical cultivation of Lo Han Guo and the cultivation of ginger (Ginger) in bare land. The effects of different cultivation methods on the growth of ginger Photosynthetic characteristics and yield effects. 【Result】 The results showed that the net photosynthetic rate of ginger was slightly higher than that of CK at early growth stage, but lower than that of CK at the late growth stage, while the stomatal conductance, intercellular CO2 concentration and transpiration rate were lower than those under CK, CK little difference. The net photosynthetic rate of ginger was higher than that of CK at early growth stage and slightly lower than that of CK at the later growth stage, while the stomatal conductance, intercellular CO2 concentration and transpiration rate were lower than those under CK, and the yield was increased by 68.1 compared with CK %. 【Conclusion】 Mangosteen-Ginger intercropping can change the net photosynthetic rate of ginger leaves, affect the yield of ginger, reduce the input, increase the utilization rate of land and increase the economic benefits.
