Prune early and middle ripe peaches in time after picking
Early and middle ripening peach trees are in the high temperature and rainy season after fruit harvest, with large shoot growth and strong ability to form secondary shoots, which is easy to cause canopy closure in the upper part of the crown, poor ventilation and light permeability in the inner chamber, affecting flower bud differentiation and pest control, and is not conducive to the improvement of yield and quality in the coming year. After fruit harvest, combined with fertilizer and water management, reasonable pruning can promote branch enrichment and flower bud formation, lay the foundation for high yield in the following year, and inhibit the outward movement of fruit parts. The specific pruning methods are as follows:
Retract overlapping branches and cross branches in time after fruit harvest, remove over-dense and weak branches and useless erect branches from wind and light in the upper part of the crown, cut off the fruiting branches at the top of the fruiting branches, and leave the basal preparatory branches, which can effectively promote their growth and enrichment, which is beneficial to the formation of flower buds and improve the quality of flower buds.
For the strong branches in the upper part of the crown, after thinning and removing the strong shoots, they can be pressed down from the sprain or sprain at the base to control their growth potential and promote flower bud differentiation. For the erect strong branches in the crown, when there is space to retain, select 2 or 3 basal branches with large angles and cut short at the weak secondary shoots to make them into a good fruiting branch group.
The backbone branches with small angle, especially the first fruit tree, can be pulled and opened at an angle. For the newly born shoot, pick the heart at 30 cm and twist the tip.
For the peach trees with bare inner chamber of the crown, the main branches were temporarily pulled to the level, and in the middle and lower part of the branches, 2-3 places were cut every 15-20 cm half-ring, so that new shoots sprouted in the lower part, and when the new shoots grew to 15-20 cm, they were coring and twisted to promote them to develop into good bore fruiting branches.

The "Seven essentials" of Bitao cultivation
Blue peach is a small deciduous and flowering tree of the genus Prunus in Rosaceae. it likes light, fertilizer, cold tolerance, drought tolerance and water and humidity tolerance. The flower buds are all born between the axillary buds of the new branches in the afternoon, with 1-2 per node, with short pedicels and double flowers. The flowering period is usually from late February to early April. It is the new favorite of Guangzhou New year Festival Flower Market in recent years. In management, it is necessary to achieve the "seven essentials": (1) after pruning the flowers in time, we should cut short all the nutritious branches and cut off the crowded branches to ensure that they will blossom more in the coming year. (2) fertilizing green peach from sprouting in time

Control of brown spot perforation of peach leaves
Occurrence rule: The pathogen overwinters mainly by mycelium on diseased leaves or diseased tissues of injured branches. The following spring, with the rise in temperature and the arrival of rain, the pathogen produced conidia. Conidia spread by wind and rain, infecting leaves, shoots and fruits. The disease occurs more seriously in low-lying, poorly ventilated, cloudy orchards or rainy years. Control methods: (1) Agricultural control: reasonable pruning. Make orchard ventilation and light transmission good, reduce the humidity of peach orchard, create unfavorable conditions for disease occurrence.
