Major causes and control methods of boron poisoning in Hongmei honey grapefruit

Excessive spraying of borax or boric acid will cause boron poisoning: If every pomelo tree is applied more than 22 borax on the soil surface, boron poisoning occurs after a period of time.
Red wine honey grapefruit boron poisoning what method to solve? The occurrence of boron poisoning of grapefruit trees has been proved through practical experiments: Each tree of grapefruit uses 1-1.5 liters of lime to spread trunk on the ground. The effect is good, but the application amount should not be too much, otherwise it will cause boron deficiency.
The symptoms of boron poisoning occurred in pomelo. The shoots of new shoots were yellow until they were fallen. After the treatment of boron poisoning, the pomelo tree was treated to strengthen the management of fertilizer and water. After the second and third years, the growth of the tree vigor, flowering, and fruiting were restored to normal.
Control methods: Borax is best not to be used as ground. Only apply 0.1% boric acid or 0.2% borax to the foliage.
After years of experimenting with boron injection experiments, borax will be sprayed once at the flower bud stage and before the flowering stage of the young fruit after flowering at the new shoot (during the fruit setting period). Do not spray it frequently in other periods. Otherwise it will cause excessive application of boron. The tree vigor is weak, and a large number of old leaves fall during the winter and spring shoot-out periods, which makes the flowering in the coming year less effective, and the fruit set rate after the flower is reduced, which affects the output of the year. Other grapefruits that lack magnesium will also weaken the tree's vigor.
