Jujube flower flowering
In order to increase the yield of jujube trees and reduce the drop of flowers and fruits, while strengthening the prevention and control of soil, fertilizer, water and pests, the following "one release and two sprays" should be done.
One put, that is, the jujube puts a bee.
Jujube is a arboreal flower. Using bees to enhance pollination, the fruit setting rate can be increased by about 1 time, the yield is increased by more than 20%, and the superior jujube nectar can also be obtained. According to the investigation, the fruit setting rate of jujubes at a distance of 120 meters from the beehives was 8.41%, and the fruit setting rate at 1140 meters from the beehives was only 3.84%, a difference of more than one time. Method of placing bees in jujube garden: Put the beehives in the jujube garden 2 days before the flowering of the jujube trees, and put 1 box of bees per hectare in the jujube garden. The effect of adding bees on jujube trees is related to the distance of the beehives. The closer to the beehives, the better the effect. The jujube garden with bee pollination is prohibited from spraying pesticides harmful to bees during flowering. The beekeeper said that "the spring puts the hedgehog and puts the jujube in the summer, and the autumn has the vitex and the scorpion. In winter, the bees are at home, and the honey can be fed."
Two sprays, namely flowering water spray and spray growth regulators, trace elements.
1 flowering water spray. As the saying goes: "Arid hot wind jujube flowers fall, cloudy days and rainy dates are full of branches." Jujube tree flowering period often caused by drought or dry wind, "focusing flowers", affecting fruit set. During the flowering period of jujube flower, choose 8:00 am or 5 pm after the windless season, spray evenly on the jujube with a sprayer, 3.5 to 4 kg per plant, spray once every 3 to 5 days. When spraying water, 0.3% urea can be added to improve the nutrient level of the tree. Where there are irrigation conditions, it is also possible to irrigate the ground during the flowering period, increase the air humidity of the jujube garden, and increase the fruit setting rate.
2 spray growth regulator, emblem element. Spray growth regulators and trace elements can effectively increase the fruit setting rate and increase the yield. In the middle and early June of the first flowering period, sodium naphthalene acetate (1010-6) or 920 (10～2010-6) was sprayed; in the middle of the middle of July, the naphthylacetate (40～6010-6) was continuously sprayed twice in the middle of the young fruit period. 3 to 5 days, can increase the yield of jujube trees by 20% to 30%.
