CO_2加富对大棚甜瓜农艺性状的影响

Effect of CO_2 Enrichment on Agronomic Character of Melon

以厚皮甜瓜“金蜜”品种为施肥对象 ,研究不同浓度 (10 0 0、12 0 0、14 0 0 μmol/mol)CO2 气肥对其农艺性状的影响。结果表明 :CO2 加富对春季大棚甜瓜生长发育、抗性和品质均有促进作用 ;平均单果重和产量增幅分别为 17.2 0 %～ 2 9.62 %和 10 .40 %～2 9.3 0 % ;CO2 加富适宜浓度为 12 0 0 μmol/mol。

Effect of different concentration CO 2 enrichment on agronomic character of Cucumis melo L.planted in plastic greenhouse were studied. The result showed:the growth, quality and tolerance to disease of melon could be promoted by fertilization of 1?000～1?400?μmol/mol CO 2.Average weight of single fruit and yield varied respectively from 17.20% to 29.62% and 10.40% to 29.30%. The optimum concentration of CO 2 in Cucumis melo L.was about 1?200?μmol/mol.
