In order to increase the yield of jujube trees and reduce the number of fallen flowers and fruit, in addition to strengthening soil and fertilizer water and pest control, it is also necessary to accomplish the following “one release and two injections†work.
One put, that is, Zaoyuan bee. Jujube is an insect-medium flower. Using bees to strengthen pollination, the fruit setting rate can be increased by about 1 time, and the yield can be increased by more than 20%. At the same time, it can also obtain superior jujube flower honey. According to the survey, the fruit set rate of jujube trees at 120 meters from the beehive was 8.41%, while the fruit setting rate at 1140 meters from the beehive was only 3.84%, a difference of more than one time. The method of putting bees in the jujube garden: The beehive is placed in the jujube garden 2 days before the jujube tree is blossoming, and 1 box of bees is placed in each jujube garden. The effect of adding bees on the jujube orchard on jujube tree is related to the distance of the beehive. The closer to the beehive, the better the effect. With jujube gardens pollinated by bees, it is forbidden to spray pesticides harmful to bees. The beekeeper said: “In the spring, the juniper puts jujube in the summer, in the autumn there are viburnum and cockroaches, and in the winter, the bees are at home and can feed molasses.â€
The second spray, that is, flower spray and spray growth regulators, trace elements. 1 Sprinkle water during flowering. As the saying goes: “Dry hot wind jujube falls, cloudy little rain jujube full branches.†Jujube flowering often made due to drought or dry wind
Become a "focal flower", affect the fruit set. In the flowering period of the jujube flower, no wind was selected before 8:00 am or after 5:00 pm. Spray the water on the jujube with a sprayer, and spray 3.5 to 4 kilograms per plant. Spray every 3 to 5 days. When spraying water, 0.3% urea can be added to increase the nutrient level of the tree. Where there are irrigation conditions, it is also possible to irrigate the ground during the flowering period to increase the air humidity of the jujube garden and increase the fruit setting rate. 2 spray growth regulators, trace elements. Spraying growth regulators and trace elements can effectively increase fruit setting rate and increase yield. In the first half of June, Naphthalene Acetate (1010-6) or September 20 (10-2010-6); During the first half of July, two naphthaleneacetic acid sodium (40～6010-6) were sprayed consecutively in the young fruit period. 3 to 5 days, can increase jujube tree production 20% to 30%.
