One, deep clearing the garden. 1 Deep turning to improve soil. To the shallow soil of Taoyuan, deepen the soil by expanding the hole within 2-3 years after planting. The area should be 10 cm below the canopy drip line and the depth should be 50-60 cm. The crown should also be 10-15 cm below the crown. To improve the growth conditions of the root system. The deep fall time is in the south from late November to late December. Combined with the application of basal fertilizer based on farm organic fertilizer. The amount of fertilization varies depending on the age, growth, and growing conditions, but the amount of basal fertilization should account for more than 60% of the total fertilization for the whole year. 2 Clear Garden. In combination with pruning, all the pests, branches and litter on the ground, fruit drop, and concentrated burning are eliminated to reduce the source of disease.
Second, prevent pests and diseases. 1 After pruning in winter, spraying Baume 5 degrees lime sulfur and 0.3% sodium pentachlorophenol to prevent overwintering pests and diseases. 2 main branches brush white. Plants with gums must first be scraped and then whitened. Whitening agent with 1 kg of quicklime, water 3-5 kg, 2 tsp of salt dubbed. The preparation method is as follows: first, the quicklime is transferred into a paste, and then a small amount of hot water is used to dissolve the salt and then poured into the water. Then, the water is adjusted to a degree of stickiness that is not a mass and can be easily painted. If you add a small amount of lime sulfur, you can also treat diseases and pests.
Third, rootstock seedlings. After a low temperature of 5-7 °C, about 70-90 days, dry peach seedlings accumulated on the dry sand have been matured and can be sown in late autumn and early winter. Soak the seed in flowing water for 2-3 days before sowing, then dry it, and then pile it in a warm place with a thickness of 10-15 cm and cover the film to germinate. After the thick shell of the hard seed is cracked, the foot base fertilizer In the deep-falling and flat-lying seedbeds, the spacing between the rows is 25 cm, the horizontal grooves are on-demand and the cover soil is 3 cm thick, and the seeding volume is about 500 kg/mu.
Fourth, winter pruning. 1 short cut. The object is a variety that results in long fruiting branches. The top of the long fruiting branches is generally not the result, and the middle flowering buds are numerous and the result is, so the ineffective part of the top is cut off. Cut about 1/3 of the length of the branch. Among them, the long fruit branches with weaker growth tend to be short and heavy, while the long fruit trees with strong growth tend to have short and short cuts. Long fruiting branches should generally retain oblique or horizontal state, should be removed is the erect branches or drooping branches; aged trees appropriate to retain part of the upright branches, in addition to dense and sparse shear in the middle and short branches, generally not short cut. In order to cultivate new shoots, branches that grow stably upright, have good lighting conditions, and develop at the apex of lateral branches can be retained as short as 12-15 cm for regeneration. As for the long branches that have become senescent for many years, they are retracted and renewed, causing them to re-elongate long branches and form short and middle fruit branches. 2 thinning pruning. The general objects are saplings and wangshu trees, which can significantly ease the tree vigor and promote its early results. Among them, the young trees mainly include drooping branches, thin and weak branches, competing branches and leggy branches. It is also possible to use secondary branches to enlarge the crown or promote its transformation into a result branch. The canopy of the adult result tree has been shaped, and a combination of truncation and debriding can be used to control the strong and weak, mainly densely cut branches, thin branches, overlapping branches, branches and branches, straight branches and leggy branches.
