摘要: 研究套作对太子参生物量和产量的影响,为这种重要中药材的合理栽培提供参考。通过连续 2个生长季的盆栽试验,以太子参单作为对照,设置大豆和玉米2种套作处理,考察套作对太子参生物量和产量指标的影响。与太子参单种相比,套作处理降低了太子参的地上生物量,增加了总生物量,显著地提高了产量,极显著地提高了根茎比;套作促进了光合产物向根系的分配,有助于太子参产量的提高,且套作大豆和玉米对提升太子参产量的效果相当;套作对太子参的单根重指标表现出了一定的促进作用,但其对太子参的增产作用主要是通过增加太子参的分根数来实现的。实际生产中可选择合适的作物与太子参套作,提高太子参产量,并获取更大的综合收益。

Abstract: The effects of relay intercropping on the biomass and yield of Pseudostellaria heterophylla were studied to provide some reference for the proper cultivation of this important Chinese medicinal herb. With P. heterophylla monoculture as the control, two relay intercropped treatments of soybean and maize were set up to test the effects of relay intercropping on the biomass and yield of P. heterophylla by pot culture experiments that carried out in two consecutive growth seasons. Compared with monoculture, relay intercropping reduced the shoot biomass, improved the total biomass, and significantly increased both root-shoot ratio and yield of P. heterophylla. Relay intercropping enhanced the distribution of photosynthetic product to root, contributed to the increment of yield, and relay intercropped soybean and maize had similar effect on increasing the yield of P. heterophylla. The yield increment of P. heterophylla was mainly due to the increase of the root quantity, although the single root biomass of P. heterophylla was improved to some extent in relay intercropping system. In order to obtain better yield and enhance comprehensive income, P. heterophylla is recommended to be relay-intercropped with suitable crops in actual production.
