Differentiation and morphological differentiation
Traditional flower promotion
▲Zinc and boron deficiency without flowers
Boron is a key element in the formation of flower vessels. It can lengthen the pollen tube and increase the number of flowers in the second year , and the fruit-setting rate is high . If the fruit tree lacks boron, it will cause small flowers, weak flowers, and more abnormal flowers, which will only bloom but not bear fruit. .
Therefore, in addition to supplementing phosphorus, there are two key reproductive elements, zinc and boron.
Flower promotion period
The autumn shoots need phosphorus, boron, and zinc for germination, and the fruits need to be supplemented by phosphorus, zinc, and boron for coloring. Phosphorus, zinc, and boron are the most critical trace elements for flower formation. The phosphorus, zinc, and boron consumed in the late autumn of the fruit trees are not replenished in time, and the accumulation of nutrients in the next year will be insufficient, which will cause excessive winter shoots to affect the coming flowers, or the quality of the flower bud differentiation in the coming year will be low, and the flower bud differentiation will not be neat, resulting in a large number of fallen flowers and weak flowers.
