Peach blossom control and promote flower
The florists of many kinds of peach blossoms called to ask how to make the peach blossoms stop growing and form more buds. The main reason affecting flower bud differentiation is the contradiction between reproductive growth and vegetative growth. When vegetative growth is too prosperous, it will seriously affect reproductive growth, that is, flower bud differentiation. Therefore, in the period of flower bud differentiation (from late May to before defoliation), attention must be paid to the balance between them in order to ensure the normal differentiation of flower buds.
1. From late May to June, peel off the top of 10-12 leaves in autumn shoots to promote flower bud differentiation, promote branching, or spray control.
2. From late August to September, the growth period of autumn shoots should be sprayed once (with 40 jin of water per packet) to ease the intensity of vegetative growth, and from late September to early October, it should be sprayed again (20-30 jin per packet of water). The aim is to make the branches stop growing before the middle of October, and the trees that are still growing should be sprayed quickly.
3. Fertilizer and water production began in the middle and last ten days of September to control shoot growth.
4. when yellow leaves and fallen leaves appear prematurely, spray agricultural nucleotides + 0.2% nitrogen fertilizer.
5. After the branches stop growing, they can be sprayed 1-2 times for better flower bud differentiation, or agricultural nucleotides + 0.2% potassium dihydrogen phosphate.
