CO_2加富对温室芹菜光合参数和产量及品质的影响

Effect of CO_2 Enrichment on Photosynthetic Parameters,Yield and Quality of Celery in Greenhouse

为提高设施芹菜品质,以芹菜早熟品种-皇后为材料,日光温室冬春茬栽培过程中增施CO_2,通过测定其光合特性、形态和品质性状等,研究CO_2加富对芹菜生长的影响。结果表明:CO_2加富显著提高了光合性能,植株变得高大粗壮,单株鲜重和干重增加,产量增幅25.33%,产品品质有效提升。

In order to improve the quality of celery in facilities,the celery variety Queen was used as test material and CO2 enrichment was applied to greenhouse environment in the winter and spring,to explore effects of CO2 enrichment on the growth of celery,by measuring the photosynthetic characteristics,morphological indexes and quality indexes.The results showed that CO2 enrichment increased photosynthetic performance,the plant height and the fresh weight were also increased,the yield increased by 25.33%,and the product quality was improved.
