This year, concubines in Hainan laughed and said that litchi didn't come to blossom. What foliar fertilizer should be added?

On the one hand, the flowering of litchi and longan is affected by the temperature change, on the other hand, it is also related to whether the nutrition of flowering is supplemented in time, on the other hand, it is also related to the growth of fruit trees. Generally, the temperature below 14℃ can normally differentiate flower buds, and 0- 10℃ is the most favorable for flower bud differentiation, while 14- 19℃ is prone to weak flowers and other problems, while above 19℃, flowers can not come, resulting in new leaves. We can't change the climate problem, but it is more conducive to the normal flowering of litchi and longan to do a good job of nutrition to promote flowers and strengthen flowers in advance, and pay attention to zinc and boron supplementation. Before and after white spots appear in litchi, it is necessary to spray micro-flower supplement and boron supplement to effectively supplement zinc and boron to help it bloom healthily. At the same time, if the treetops are lush, it is necessary to control nitrogen and do a good job in the early treetops control.
