How to control the size of bayberry
Yangmei is a typical fruit tree with regular and alternate results every other year. Therefore, the overcoming of size and annual result is an important project in the production of bayberry, which can be applied to ring cutting, suppression, promotion, flower protection, fruit thinning and other technical measures. Regulation.
1, ring cutting suppress the tip of the flower to protect the fruit. The traditional measure to control the flower and fruit is to gird up or use chemical hormones. This method can receive good short-term benefits, but it is extremely damaging to tree vigor, and can cause severe tree death. At present, extensive application of ring cutting smearing non-pollution cationic active agent "promoting Huawang No. 2" technology, control shoot promotion flower, increase fruit setting rate, and eradicate the size of the year.
2. Trim large branches. For the grown-up grown red bayberry tree, its trunk and main branch adopt the method of “cutting the branch and controlling the tree crownâ€, “deletion of the inner branch, and opening the skylightâ€. For the newly planted young trees, the method of “putting in the first place and then cutting†can be implemented. In other words, the first year was allowed to grow. After the first year of the fourth year, it gradually adjusted to dwarfing and opened a tree. Trimming wounds should be promptly painted anti-corrosion film to protect the wound healing tissue growth.
3, a reasonable fertilization. More potassium fertilizer should be applied once a year. Less application of phosphate fertilizer, because too much phosphorus, often resulting in more fruit, a small, poor quality, exacerbated the phenomenon of size. Appropriate nitrogen fertilizer, promote young fruit expansion. Saplings are suitable for chemical fertilizers, and adult trees are mainly applied for farmland fertilizers.
