Summer pruning method of pomegranate
First, girdling. It is mainly used for strong branches on young and prosperous trees. Selecting the smooth part of strong branches according to width 0.3cm girdling in the middle and first ten days of June can obviously promote the differentiation and formation of flower buds and increase the fruit setting rate. Second, pick the heart. Removal of top shoot 5cm or shoot growth to 30~40cm at flowering stage can promote flower bud.

Fertilization Management techniques for High-yielding Pear trees
About a month before the pear fruit ripens, the growth rate accelerates, which is called the fruit expansion period. At this time, topdressing can improve photosynthetic efficiency and promote nutrient accumulation, which is beneficial to fruit expansion and flower bud differentiation. This topdressing will not only increase the yield of the current year, but also lay the foundation for the results of the coming year. 525 Shandong Fruit Network fertilization period is generally in the fruit.
