First, reasonable control. Before flowering (about the beginning of May), each plant should be applied with 0.5-0.7 kg of urea, 0.25 kg of initial fruit, and a nitrogen, phosphorus and potassium compound fertilizer after flowering (in the middle and late June). , about 0.75 kg per plant. Spraying 10~50ppm gibberellin solution at the beginning of full bloom or spraying 0.3% borax solution during full bloom can significantly improve the fruit setting rate.
Second, watering before flowering, spraying water during flowering. If the soil is too dry before flowering, it should be timely flooded to ensure stable fruit setting. Spraying water every 2 to 3 days during the flowering period of jujube can promote pollination and fertilization and increase the fruit setting rate.
Third, the jujube is a bee. Jujube is a typical arboreal flower. The flowering period can increase the fruit setting rate. Generally, 1 box of bees can be placed every 6-10 mu.
It is very important to control microbial activity in cutting fluid containers. Both bacteria and fungi can cause problems because they metabolize the components of the cutting fluid, resulting in the production of biofilm/mucus (large quantities of biofilm/mucus can exacerbate foaming problems and sticky surfaces) and secondary metabolites in the form of short-chain organic acids. The latter can result in a lower pH of the cutting fluid and an increased risk of corrosion. It is also important to note that high levels of bacteria and fungi can cause health problems for those operating the machines.
If the pH drops to less than 8.5, it may indicate bacterial growth in the cutting fluid. In such cases, we recommend measuring bacterial growth and replacing the cutting fluid if the test is positive.
Other signs of bacterial growth are a bad smell and fungal/bacterial film on top of the cutting fluid.
