- 摘要:
- 为促进温室枣树增产,以灵武长枣为研究对象,研究不同浓度CO2施肥对温室枣树果实品质及产量的影响。通过预设各隔间的CO2浓度,且在枣树果实成熟过程中维持在设定值,其中处理T1~T4依次为600,800,1 000,1 200 μmol?mol-1,对照(CK)为400 μmol?mol-1。结果表明:随着CO2浓度的升高,枣果的总糖含量、还原性糖含量、维生素C含量、糖酸比及产量有显著的增效;整体来看,当施入CO2浓度为800 μmol?mol-1时,效果最佳,其中总糖含量较CK提高70.16%,还原性糖含量提高64.46%,维生素C含量提高55.81%,糖酸比提高25.71%,产量提高27.84%;差异较CK显著(P<0.05),但与增施高浓度差异并不显著(P>0.05)。因此,CO2浓度施肥能有效改进温室枣树果实的品质及产量,但增施过多的CO2并不能有效提高产量。
- Abstract:
- In order to promote yield increase of jujube trees in greenhouse,we investigated the effects of CO2 fertilization on fruit quality and yield of Lingwu jujube in greenhouse.By presupposing the CO2 concentration in each compartment and maintaining the same compartment at the set value during fruit ripening,the treatments T1~T4 were 600,800,1 000 and 1 200 μmol?mol-1,and the CK was 400 μmol?mol-1.The results showed that with the increase of CO2 concentration,the total sugar content,reducing sugar content,vitamin C content,sugar-acid ratio and yield of jujube fruits increased significantly; Overall,when the CO2 concentration was 800 μmol?mol-1,the effect was the best,in which the total sugar content was increased by 70.16%,the reducing sugar content increased by 64.46%,and the vitamin C content increased by 55.81%,the ratio of sugar to acid increased by 25.71%,and the yield increased by 27.84%.The difference was significant compared with CK(P<0.05),but the difference was not significant with the increase of high concentration(P>0.05).Therefore,CO2 concentration fertilization could effectively improve the quality and yield of jujube fruit in greenhouse,but too much CO2 could not effectively improve the yield.
