六月草莓品种在日本已广泛种植。由于它们在冬季和春季收获,夏季和秋季的产量很少。为了实现全年稳定的供应,我们需要扩大四季结实品种的生产面积。在这里,我们研究了是否有可能增加干物质(DM)生产和果实产量增加冠层内的CO2浓度,通过局部应用,以促进光合作用在夏季和秋季保护地栽培。研究了冠层CO2浓度、干物质生产特性、产量特性、果实品质、投影叶面积、累积光截获和光能利用效率。我们证实,植物冠层内的CO2浓度可以增加在夏季和秋季(对照; 398 ppm,CO2; 1280 ppm),显着增加DM产量和总产量(对照; 349克,CO2; 447.5克)。我们认为,局部施用CO2增加了投影叶面积,从而增加了累积光截获。该方法有助于提高夏秋设施栽培的果实产量。
June-bearing strawberry cultivars have been widely grown in Japan. Since they are harvested in winter and spring, little produce is available in summer and autumn. To achieve stable year-round supply, we need to expand the production area of ever-bearing cultivars. Here, we examined whether it is possible to increase dry matter (DM) production and fruit yield by increasing the CO2concentration within the plant canopy through local application to promote photosynthesis in summer and autumn protected culture. We investigated the CO2concentration in the plant canopy, DM production characteristics, yield characteristics, fruit quality, projected leaf area, cumulative light interception, and light use efficiency. We confirmed that the CO2concentration within the plant canopy could be increased in summer and autumn (Control; 398 ppm, CO2; 1280 ppm), significantly increasing DM production and total yield (Control; 349 g, CO2; 447.5 g). We consider that local application of CO2increased the projected leaf area and thus cumulative light interception. This method may help to increase fruit yield in summer and autumn protected culture.
