【摘要】 光合作用是人参产生干物质的基础,对人参的产量和品质有着重要的影响。简述了人参的光合特性,归纳了人参光合特性日变化及不同生育期变化的规律,分析了影响光合作用特性的因素,包括光强、光质、温度、CO2、水分、源-库关系、光斑对人参光合特性的影响。指出了在人参栽培实践中存在的对光合作用特性的不重视、只强调单一因素对光合特性的影响等问题及解决对策,并提出了展望。更多还原

【Abstract】 Photosynthesis is the basis of ginseng dry matter produced and it has important effect of ginseng on yield and quality. The author reviewed the photosynthetic characteristics of ginseng, summarized the photosynthetic characteristics of diurnal variation and the variation of different growth stages of ginseng,analyzed the factors affecting photosynthesis, including light intensity, light quality, temperature, CO2, source-sink correlation, light spot influence the photosynthetic characteristics of ginseng. The problems were pointed out, for example the photosynthetic characteristics of ginseng were not given too much emphasis, and only one single factor was emphasized on the influence of the photosynthetic characteristics of ginseng. The future research was provided.更多还原
