First, take care of
Flowering management is very important. All new dates in spring are erased. When the second branch grows to a certain degree, the vegetative growth of the jujube tree almost synchronizes with the reproductive growth. The vegetative growth and reproductive growth must be coordinated. The relationship, so that it to the jujube hanging nutrient supply, so that jujube hanging nutrition, in order to ensure flowering fruit set.
Second, flower spray
Pollination of jujube and pollen germination are related to temperature and humidity. The suitable temperature for jujube pollen germination is 24-26°C, relative humidity is 70%-80%, and the humidity is too low. As the recent flowering season often encounters high temperatures and dry weather, the phenomenon of "defloration" is prone to occur. Therefore, spraying water during the flowering period can not only increase the air humidity, but also reduce the temperature. Spray water 2-3 times in general years, strict intervals of 1-3 days.
Third, the flowering bee
Jujube trees are typical insect-infested flowers with rich nectar and strong aroma. Bees are the best pollinators. The pollen viability and germination rate of the jujube pollen are the highest during the bud split period and the sepal flattening period, so the effective pollination period of the jujube flower is shorter. According to the survey, the percentage of fruit setters pollinated on the first day of flowering was 50%; the percentage of fruit setters on pollination on the second day of flowering was 2%; all pollinations later fell off. Therefore, timely pollination of jujube flowers is particularly important. Studies have shown that flowering at the flowering stage can increase the fruit setting rate by more than 1 time.
