摘要
通过增施钙肥、调节土壤pH值,促进壶瓶枣树吸收钙素,研究壶瓶枣裂果与枣果含钙量的相关性.结果表明,壶瓶枣果实含钙量在一定程度上可减轻枣果裂果,枣果裂果与果实含钙量呈负相关,相关系数R2在0.186 5～0.2820之间,在数据上支持了枣果含钙量不是产生裂果的根本原因.
To study the correlationship between the dehiscent fruit and fruit calcium content in Huping jujube,the research promoted the calcitonin absorption of the Huping jujube by increasing calcium fertilizer application and adjusting soil pH value.Results showed that,the fruit calcium content in Huping jujube could reduce the dehiscent fruit to some extent and there was a negative correlation between the dehiscent fruit and fruit calcium content.The correlation coefficient R2 was in the range of 0.186 5-0.282 0,which supported the conclusion that the jujube fruit calcium content was not the root cause of the dehiscence.
