Jujube management: why do jujube trees not bear fruit?
Why don't jujube trees bear fruit? Please introduce the reasons why the jujube tree does not bear fruit, there are the following three main reasons: the jujube tree does not bear fruit: the solution: the jujube tree can be peeled at the base of the main branch in full bloom, reaching to the xylem with a width of about 0.5 cm, roughly peeling the bark as thick as it is. The second reason for the non-fruiting of jujube trees: there is no pollination tree, such as Sihong jujube and other fresh jujube varieties, generally need to configure pollination varieties, otherwise the fruit rate is low. Solution: grafting pollinated varieties on the upper branches of jujube trees. The third reason why jujube trees do not like fruit is that the stigma viscosity of female flowers decreases in dry weather during the flowering period, which is easy to lose activity, which affects pollination and fertilization and decreases the fruiting rate. Solution: jujube trees can be sprayed with water to increase humidity between 8 am-10:00 and 5 pm during flowering.
