产CO2气肥残余物对番茄产量和品质的影响

为通过田间试验,研究和比较了商品有机肥和产CO_2气肥残余物对番茄生长和品质的影响。试验结果表明,施用商品有机肥和产CO_2气肥残余物均可促进番茄产量的增加,分别较CK处理增加了24.02%和28.59%,但二者之间没有达到显著性差异;通过对各处理中番茄品质指标的结果分析,可以得知,产CO_2气肥残余物显著降底了番茄坏果率,比有机肥和CK处理分别降低了18.18%和33.33%。产CO_2气肥残余物促进了番茄可溶性糖和维生素C含量的提升。由此可知,产CO_2气肥残余物较商品有机肥,可以增加番茄产量、显著降低番茄果实坏果率并改善番茄果实的品质。

Effects of Fermentation Residues of CO2 Fertilization on Tomato Yield and Quality

A field experiment was conducted to investigate the effects and differences of general commercial fertilizer and fermentation residues of CO₂ fertilization on the yield and quality of tomatoes. The results showed that the both fertilizers could enhance tomato yield, which increased by 24.02% and 28.59% than CK under general commercial fertilizer and fermentation residues of CO₂ fertilization treatments, respectively. And there was no significant difference between the two fertilizers. According to analyses on the indexes of the tomato quality, the fermentation residues of CO₂ fertilization significantly decreased the bad fruit rate and significantly promoted the concentrations of soluble sugar and vitamin C, for example, it deceased the bad fruit rate by 18.18% and 33.33% compared with general organic fertilizer and CK treatments, respectively. Therefore, the fermentation residues of CO₂ fertilization has the more advantages to enhance the tomato yield, decrease the bad fruit rates and promote the fruit quality.
