摘要: 为有针对性地做好农业气象服务,指导设施农业生产,以‘美红2 号’番茄为试验材料,通过日光温室内自然环境浓度CO2的番茄为对照,研究增施不同浓度CO2对日光温室番茄生长发育的影响。2 年的试验观测结果表明:日光温室增施CO2能促进番茄的生长发育,表现为番茄的株高、茎粗、叶片数、结果个数增加及产量提高;且增施CO2浓度1200 mg/kg处理比700 mg/kg处理效果更好。说明对日光温室的番茄增施CO2可以促进其光合作用,对番茄的生长发育和产量的提高有利。

Abstract: The paper aims to provide targeted agricultural meteorological services to guiding the facility agriculture production. We studied the effect of different concentrations of carbon dioxide on greenhouse tomato growth and development, with‘Meihong 2’tomato as the experimental material, by comparison with the tomato under natural environment CO2 concentration in greenhouse. After two years of experiment, the results showed that the increase of CO2 could promote the growth and development of tomato, and the plant height, stem diameter, leaf number, fruit number and yield were increased. The effect of increasing CO2 concentration by 1200 mg/kg was better than that by 700 mg/kg. It is suggested that CO2 enrichment in solar greenhouse can promote the photosynthesis of tomato, and is beneficial to its growth and yield.
