喷施醋酸钙对赞皇大枣裂果的影响

Effects of Spraying Caluim Acetate on Fruit Craking of Zanhuangdazao

研究田间喷施Ca(Ac)2对赞皇大枣裂果及树体钙的影响。结果表明,随着喷施Ca(Ac)2质量分数的升高,裂果率逐渐降低;喷施1%,2%Ca(Ac)2处理的裂果率分别为31.58%,31.25%,比对照分别降低31.59%,32.30%。对钙与裂果率的相关性分析表明,叶片和果皮中的钙与裂果率呈负相关关系。喷1%~2%Ca(Ac)2能显著增加树体的Ca含量,降低裂果率。

A trail was undertaken to evalue the effects of various rate of Ca（Ac）2 solution on fruit cracking rate and the contents of Ca in jujube. The results showed that as the concentration of Ca（Ac）2 increased, the cracking rate decreased. Compared with CK, the rate of fruit cracking was 31.58% and 31.25% by the treatment of spraying 1% Ca（Ac）2 and 2% Ca（Ac）2, respectively, which decreased31.59%, 32.30%, respectively, compared with CK. Correlation analysis between calcium and cracking rate showed that calcium in leaves and pericarp was negatively correlated with fruit cracking rate. Spraying 1%-2% Ca（Ac）2 can significantly increase the Ca content of trees and reduce the cracking rate.
