Jujube trees need high yield and fruit setting is the key. Management depends on the technology, take the fruit and find the law. The flowering period should be tightened, and the secret must be kept in mind. First, the flowering period of jujube trees is longer, usually 35 days from May 25 to June 30. Florescence is divided into early flowering, full flowering and late flowering. The flowering period was around June 8. The flowering rate at the flowering stage and the final flowering stage is high, accounting for 50% of the total fruit. Second, the fruit setting rate The flower of the jujube tree is very dense. The big fruit date hangs and blossoms more than 100, and the fruit setting rate is only 1%. Jujube flowers hang around 300 flowers per flower, and the fruit setting rate is generally 2%. Third, pollen date is an insect-mediated flower, it can not rely on its own wind or pollination. The flowering period is to use insects such as bees to pollinate, or drugs to pollinate, in order to increase the fruit setting rate. Fourth, temperature and humidity June weather, high temperature and little rain, hot dry wind and more. The temperature is suitable for fruit setting when it is about 35°C, and it is not suitable for fruit setting below 28°C. The highest rate of fruit set is in high temperature, no sun, and no wind and sultry weather. Drought and high-temperature weather are not easy to set fruit and must be sprayed to protect the flowers. Humidity is not suitable for fruit set. V. Hormone fruiting According to the characteristics of long flowering time and low fruit setting rate of jujube trees, the fruit set can be used in flowering stage, such as GA3, 2,4-D pollinating hormone, cytokinin, plus 20% potassium nitrate, vital force source. , Nongfeng Hercules, phosphorus nitrate, rare earth boron fertilizer, etc., can increase the amount of fruit set 1-2 times. 6. Jujube Jujube Jujube is a traditional folk management model and can play an effective role in shutting off the flow. In the full flowering period every 3-5 days, jujube can improve fruit setting rate and increase yield.
