According to the space in the shed and the requirements of tree growth, under the condition that 3~4 basic backbone branches are reserved for each plant, large branches, weak branches, no flowering branches, disease and insect branches, over-dense branches and overlapping branches disturbing the tree shape are thinned out, medium and long fruit branches on the back are thinned out or flattened, extended branches are slowly laid out, medium and long branches are laid out, and drooping fruit branches are cut short. The pruning amount is controlled at about 10% of the total amount, so that the peach tree after pruning retains 8

1. Pruning in order to ensure a better yield of greenhouse peaches, pruning should adopt the method of long branch pruning, leaving more branches and removing branches as much as possible. According to the requirements of space and tree shape growth in the greenhouse, under the condition of retaining 3 to 4 basic backbone branches per plant, remove the big branches, weak branches, non-flower branches, disease and insect branches, over-dense branches and overlapping branches, remove or flatten the middle and long fruit branches on the back, slowly extend the long fruit branches, long the medium long fruit branches, and cut short the drooping fruit branches. The amount of pruning is about 10% of the total, so that a single peach tree retains 80,140 compound flower buds after pruning.

Second, fertilize and irrigate 3000 kg of fully mature chicken manure or soil fertilizer per mu, 10 kg of urea, 8 kg of diammonium, 8 kg of potassium sulfate, or a considerable amount of multicomponent compound fertilizer. Dig 3 to 4 holes of 30 cm in length, width and depth between plants or rows, and apply them centrally.

Third, clean up the shed and gently remove the leaves by hand, remove weeds, remove all the fallen leaves, weeds, branches, etc. out of the shed, concentrate and bury them deeply or burn them, and then spray 4-5 Bomedo stone sulfur mixture throughout the garden to eradicate overwintering germs and eggs.

Fourth, to keep the temperature in the greenhouse mainly depends on the measures such as cover, opening and closing vents and so on. When the temperature is lower than 10 ℃ in late autumn, it is best to begin to buckle the shed at 7 ℃ ~ 8 ℃, and cover the canopy outside the greenhouse. The opening of the canopy is just the opposite of the heating management. The vents are opened at night, and the vents are closed during the day. With the drop of temperature, when the temperature in the greenhouse is lower than 7 ℃ day and night, the vents will no longer be uncovered and opened. The aim is to keep the air temperature in the greenhouse between 0 ℃ ~ 7 ℃ as far as possible to meet the cooling requirement of peach trees. Most varieties can pass dormancy smoothly after concentrated treatment for about 30 days.
