The management of jujube flowering period is very important. The number of jujube fruit is closely related to jujube flower. Therefore, farmers should do the necessary care before, during and after jujube flowering. So, how is the jujube flowering period managed?
How to manage the jujube flowering period?
Jujube flower flowering management 1 : Flowering ring stripping of jujube trees that have entered the fruiting period and have a tree age of 12 to 15 years, and are stripped at the flowering stage.
Method: On the trunk of jujube tree about 15 cm away from the ground, cut 2 times with a sharp knife, the width is 4-6 mm, and the xylem is deep, and the skin can be peeled off. The ring stripping is carried out once a year, and the base of the trunk is gradually stripped upwards, 3 to 5 cm apart. It is necessary to grasp the principle of three non-exfoliation, that is, the small tree does not strip, the weak tree does not strip, and the stripping period does not strip.
Jujube flowering period management 2 : flowering water jujube tree flowering period often encounters high temperature and dry weather, it is easy to cause the jujube stigma to wither and fall off, should spray water on jujube tree crown during flowering period, increase humidity and promote pollen germination.
The water spray should be carried out before the high temperature every day. Each plant sprays 3 to 4 liters, sprays once every 2 to 3 days, and even sprays 3 to 4 times.
Jujube flower flowering management three : jujube topping in the jujube flowering period, when the new branch reaches 30 cm long, the jujube head that does not make the updated branch is cut off, leaving 3 to 4 secondary branches to control the jujube head and grow long and reduce Nutrient consumption.
Management of jujube flowering period 4 : spraying boron and boron during flowering can promote pollen absorption of sugar, activate metabolic process, stimulate pollen germination and pollen growth during flowering
The leaf surface is uniformly sprayed with a borax solution of 0.2% to 0.3% or a boric acid solution of 0.1% to 0.2%.
Management of jujube flowering period: Foliar spray fertilizer is sprayed with 0.3%-0.5% urea solution at the initial flowering stage to improve the quality of flower bud differentiation.
In the flowering stage and the young fruit stage, foliar spraying with a mixture of 0.3% urea solution and 0.4% potassium dihydrogen phosphate solution can reduce the drop and fruit drop, increase the fruit setting rate, increase the single fruit weight, and improve the jujube fruit. quality.
Management of jujube flowering stage 6: Spraying growth regulator and trace element during flowering stage spraying 10×10-4 gibberellin or 2% chlormequat solution and 0.2% zinc sulphate solution can effectively improve jujube Tree fruit rate...
The above is the specific method of jujube flowering management. Farmers must take good care of them. I believe that jujube trees will have a bumper harvest.
