Winter is also a dormant period for peaches and plums, and the focus of management is also on pruning and clearing. (A) The peach tree pruning winter shear can be carried out after the fall of autumn leaves and before the budding of next spring. Peach trees require strict lighting. When shaping, many center leaders are not employed, but adopting a happy-shape. Dry height 35 to 45 centimeters, scattered with three main branches. The main branch opening angle varies depending on the species. The erection angle of the main branch of the erect type should be larger, preferably 50 to 60 degrees, and that of the open or semi-open type should be 45 to 50 degrees. In the main branch about 60 cm with 1 to 2 vice main branch, the whole tree can be equipped with 3 to 6 vice main branch, the base angle of 75 degrees. The main branches of the extension branch can generally stay 60 to 80 cm, the direction of the backbone branches should be chosen to stay outside the bud extension. The collaterals can be appropriately long, about 2/3 of the main branch, and the angle is larger than the main branch. The extension branches are lower than the main branch and maintain their affiliation. Adult tree winter pruning is mainly short pruning and pruning pruning. Short cut pruning is to cut the branches short, cut off the unfruitful part of the long fruiting branches, which is about 1/3 of the whole shoots, and retains the fruitful growth results (commonly about 25 cm), and the weak fruiting branches can be Heavy and short cut, long fruit branches with strong growth buds on the upper part of the flower buds must be light and short cut. Long fruiting branches should generally be preserved obliquely or horizontally, except for erect or pendulous branches. Short fruiting branches can be selected to be relatively thick, with a large part of the flower buds that retain their fullness. Every 10 centimeters, it is advisable to keep an oblique or upright short fruit branch. In order to cultivate new shoots, two similar branches are left on the mother branch. The upper branches are trimmed according to the result branches, and the result is that the lower branches only leave the base part short and truncated, and two new shoots are drawn to form the second year result branches. Sheng fruit 6 to 7 years old trees, backbone branches retract and update in time, can stay 30 to 50 centimeters, or even retracted to the biennial branch, to prevent the lower branches of dead. Pay attention to the results of the branch culture update. At the same time as the result, it is necessary to keep a certain renewed branch. At the same time, it is necessary to control the upper part of the crown and peripheral branches to prevent the inner part from being empty. For the lower and inner litchi groups to shrink and combine, weak to stay strong, raise the angle, pay attention to rejuvenation. The densely growing shoots on the backbone or branch groups were removed from the base. (b) Prunus prune. Pruning Lishu plastic generally uses a natural happy shape, there is no center trunk above the trunk, only 3 major branches, dry high general level is 60 to 70 centimeters, about 50 centimeters of mountain, in the year 6 ~ In July, the main branch was selected on the main trunk with three branches distributed evenly and forming a 40-50 degree angle with the main trunk. When cutting in winter, the main branch can generally be cut 45 centimeters. Other branches adopt slow-release, and there is a space for growth as an auxiliary vegetative branch, and thinning and cutting of dense branches. In the second year of winter shearing, the extension branch of the main branch continued to be short cut, and the clipping length was similar to that of the previous year. All the short, medium, and long fruiting branches growing on the main branch should be slowly placed. For long branches with a good angle, 40 to 60 centimeters away from the main trunk, 2 are selected as the deputy main branch, and each main branch is deputy. The main branches are preferably on the same side of their respective main branches and have a shorter clipping length than the main branches. After entering the full fruit period, the result is dominated by clustered short fruit branches and short fruit branches. Pruning at this time should be based on the combination of sparse and short cuts. For the growth branches or long fruiting branches that were born on the stems of the year, they will be overly dense and sparse, and the rest will be long, without trimming or light shearing, and the lower part will form clusters of short fruit branches or short fruit branches as the resulting base branches. Cut off the competition branches, leggy branches, sprouting twigs and dead branches of pests. Results The culture of the shoots should be grown within a length of 50 cm to grow full or long fruiting branches. Growing branches or long fruiting branches, such as oblique or nearly horizontal branches, can be long-distance without pruning; if the growth is strong, close to vertical and long, it can be cut 1/3 to promote the germination of the base of buds. Remove stubborn strong branches, choose to leave the oblique branches of the growing trend of the moderately inclined branches appropriate short cut, the lower short fruit branches can be left to the results, the main branch, the lateral branch and the deputy main branches of the result on the base branches of short fruit or short fruit branches and fruiting branches and results After the top buds continue to form short fruit branches, if the students are born too dense, they can stay good or bad, and properly remove them. Results The results of the two-year and three-year results were the best for the base branches, with the largest number of fruit with a length of 20-40 cm. Exceeding this period, most short-fruiting branches have declined, resulting in few results. At this time, these branches should be updated in time to stay weak. In the first year, a certain number of result bases must be cultivated. After three years of results, they will be removed from the base or short cuts and rotations will be updated. (III) Clearing the winter gardens, reducing the number of pests and diseases, peaches, and plum gardens Every year in November, the whole garden is plowed to loosen the soil and destroy the living environment of the underground overwintering pests; cut off the dead branches of the pests, eradicate the surrounding weeds, and remove the dead branches. , leaves, pests and branches, weeds, concentrated burned; brush the trunk white; scrape the tree flow plastic, with 402 fungicides 100 times liquid smear the disease. Before sprouting, the whole park sprayed 5 Baume degrees of lime sulfur to reduce the source of disease; open drainage ditch to prevent waterlogging.
