Abstract
[Objective] The aim was to study effects of calcium spraying on calcium absorption of nectarine fruit under protected cultivation and provide theoretical basis for the improvement of nectarine fruit quality.[Method] Nectarines sprayed with calcium under protected cultivation were used to study the change of calcium content during the fruit growth and the effects of calcium absorption.[Result] The result showed that:(1)Given natural circumstance,there was different in the calcium content of the fruit for three nectarine varieties during the fruit growth,the change of Yanguang calcium concentration was unique M-shape, both Chaohongzhu and Lichun went up at beginning and then lowered in the fruit calcium concentration.(2)The Ca2+ concentration of the nectarine fruit increased obviously after spraying calcium and was all higher than the control during the fruit growth,and Chaohongzhu,Yanguang,Lichun fruit Ca2+ concentration of calcium treatment was markedly(P0.05)higher by 17%,15%,12% than the control on 15 days after full blossom and was significantly(P0.01)higher by 34%,29%, 28% on 55 days after full blossom.[Conclusion] Spraying calcium nutrition could significantly improve nectarine fruit calcium content.
