喷施大生M45防止枣裂果研究

Prevention of Fruit Cracking of Chinese Jujube by Spraying Dasheng M45

从枣果膨大到白熟,每隔15 d喷施1次大生M45,连续喷5~6次,可有效防止枣果成熟遇雨裂果,防效达94.8%~96.3%。同时,可促进枣果果面光洁和着色,提高枣果质量。据分析,大生M45可在植物表面形成一层致密的保护膜,有效防止雨水从枣果表面进入果肉,阻止了果肉细胞迅速吸水膨大;大生M45所含的锰锌离子具有叶面肥的作用,促进了枣果的果皮和果肉细胞排列整齐紧密,几何形状好,细胞之间相互形成张力,增强了果实抗裂果能力,从而防止了枣果成熟遇雨裂果,提高了枣果质量。

Dasheng M45 could effectively prevent jujube fruit cracking when it is continuously sprayed on the fruit every 15 days for 5-6 times during ripening process in raining day.The control effect was as high as 94.8% to 96.3%.Meanwhile,it could make fruit surface clean and promote color formation to enhance fruit quality.It was reported that Dasheng M45 could produce compact protective film to effectively guard rain against fruit pulp,which deterred pulp cell rapidly by absorbing water and swelling.The component of Mn2＋,Zn2＋ contained in Dasheng M45 had the function of foliar fertilizer,making the cells of jujube fruit peel and pulp trim,close and good in geometry.The tension between cells increased the ability of fruit cracking resistance,thereby preventing fruit from cracking,and improving the fruit quality.
