Winter turning through the winter turning can loosen the soil, enhance the permeability of the soil, improve the physical and chemical properties of the soil, create a good environmental conditions for the growth of peach; and can effectively control the base of the pest, the young tree can be in the crown and the vertical part of the crown It is about 1 meter deep and it is enlarged year by year until it is connected. The depth of deep plowing is appropriate to 20-30 cm. The big tree can be combined with basal fertilization to carry out deep plowing in the whole garden. It should be noted that it should be shallow near the trunk and deeper away from the trunk.
Fertilizers are mainly decomposing organic fertilizers that are slow-acting, including organic organic fertilizers and self-refining livestock and livestock manure. 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. The fertilization method was mainly based on furrows, and the depth of 40 cm and the width of 30 cm were opened on both sides of the vertical ground on the periphery of the peach tree canopy. Ditches were made around the circumference of the canopy and the fertilizer was applied to the soil after the application.
Winter pruning
The pruning of the young tree's pruning juvenile tree is mainly to expand the canopy, laying a good tree-like foundation for the subsequent high yield. When pruning, according to the requirements of the tree, look at the pruning of the tree, choose, equip and cultivate the main branches and side branches according to local conditions, and properly maintain the auxiliary branches and the resulting branches. At the same time, the angles and growth trends between the main and lateral branches are adjusted in a timely manner so that they can be clearly distinguished and occupied, and each has its own space.
After 5 to 6 years of pruning and fruiting of fruit trees, peach trees begin to enter the full fruit period. The main tasks of pruning are to maintain the balance of the tree vigor in all parts, adjust the balance of the growth potential of the main and lateral branches, and cultivate and update the branches and branches to prevent premature aging and emptiness in the internal organs.
Pest Control
The peach tree branches, peach bags, and scraped old skin that were cut by the winter gardeners of the Qingyuan Garden should all be cleared out of Taoyuan and be treated in a centralized manner to effectively control the base number of diseases and insect pests.
After the winter pruning, the Baume 5 degree lime sulfur and 0.3% sodium pentachlorophenol were sprayed to prevent overwintering diseases and insect pests.
Brush whitening agent 1 kg of lime, 3 to 5 kg of water, and 2 tsp of salt. 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.
