本文研究了CO2富集对大通风温室栽培番茄植株生长和产量的影响。在本研究中，CO2富集是指将温室内的CO2浓度维持在与大气CO2水平相同的水平。在春夏期和夏秋期，对番茄植株（Solanum lycopersicum L.）进行了CO2富集和CO2不富集两种不同CO2条件下的栽培。在春夏作物中，CO2富集栽培的番茄植株叶片干重和叶面积均大于CO2不富集栽培的番茄植株。在春夏作物和夏秋作物中，由于CO2的富集，单株果实总产量增加。在春夏作物中，CO2富集使总果实产量和正常果实产量均有提高。但在夏秋作物中，由于CO2富集，果实总产量增加，正常果实产量与果实总产量之比下降。这些结果表明，CO2富集可能会增加不同种植季节果实畸形的发生率。CO2富集对果实产量的影响受栽培期环境条件差异的影响。综上所述，有必要评估温室内环境条件是否适合植物在CO2富集条件下生长。
The present study examined the effect of CO2 enrichment on the growth and yield of tomato plants cultivated in a large-scale greenhouse with a highventilation rate. In this study, CO2 enrichment referred to maintaining the CO2 concentration inside the greenhouse at the same level as the atmospheric CO2 level. Tomato plants (Solanum lycopersicum L.) were cultivated under 2 different CO2 conditions ―one group of plants was cultivated under CO2 enrichment, and the other was cultivated under CO2 non-enrichment― during the spring-summer and summer-autumn periods. In the spring-summer crop, leaf dry weight and leaf area of the tomato plants cultivated under CO2 enrichment were greater than those of the tomato plants cultivated under CO2 non-enrichment. In both the spring-summer and the summer-autumn crops, the total fruit yield per plant increased because of CO2 enrichment. In the spring-summer crop, CO2 enrichment led to increase in both the total fruit yield and the normal fruit yield. However, in the summer-autumn crop, the total fruit yield increased and the ratio of the normal fruit yield to the total fruit yield decreased because of CO2 enrichment. These results reveal that CO2 enrichment might increase the incidence of fruit malformation according to the cropping season. The effect of CO2 enrichment on the fruit yield was influenced by differences in the environmental conditions during the cultivation periods. In conclusion, it is therefore necessary to assess whether the environmental conditions inside the greenhouse are suitable for plant growth under CO2 enrichment.
