After the harvest of peach trees, the trees are extremely weak. If the management of orchards after harvesting is not strengthened, it will be difficult for peach trees to adapt to the harsh climate conditions in winter, resulting in weakened tree vigor and a direct impact on the output of the following year.
First, fertilizer and water management
Application of basal fertilizer: Fertilizers are deferred organic fertilizers, including organic fertilizers and self-constructed livestock and livestock manure. The amount of fertilizer used for adult fruit trees per acre as an example: mechanism of organic fertilizer 1? 1.5 tons, 1.5 to 2 tons of farmyard manure. The fertilization method is mainly based on furrows, with a depth of 40 cm and a width of 30 cm on both sides of the vertical ground on the periphery of the peach tree crown, and the length of the circumference of the circumference of the canopy is about one quarter (per side) of the circumference, and the fertilizer is mixed with the excavated soil. After the introduction.
Clean up the ditch system: The peach tree is extremely resistant to waterlogging. It will die if it is flooded for more than one day during the growing season. With the use of winter time, the Taoyuan Inner Ditch system will be cleaned and maintained, and the drainage system will be perfected. It can guarantee the smooth drainage of orchards in the rainy season in the coming year, reach the condition of no water in the rain ditch, reduce the groundwater level, and reduce the impact of water accumulation on the growth of peach trees.
Second, pruning
Pruning of juvenile trees: The main task is to expand the canopy, strive for early results, and lay a solid foundation for future yields. When pruning, according to the requirements 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.
Fruit pruning: After 5 to 6 years of colonization, peach trees begin to enter fruity stages. The main task of pruning is to maintain the balance of tree vigor in all parts, adjust the balance of the main and lateral branch growth potential, and cultivate and update the branches and branches to prevent premature senility and internal guilt.
Third, dormancy control
Peach trees are the easiest to pull, severely impeding light and ventilation, and competing for tree nutrition. In the dormant period of the peach tree, two rows of holes are drilled in the tree skin or the tender branch of the main branch with a cone needle, and then the brushed fruit ring presses the fruit tree cation activating agent “Huo Hua Wang No. 1†to enter the tree body to disinfect and control. The swiftness of the raft will cause the peach tree to bloom early, blossom more, not fall flowers, and bear fruit.
Fourth, deep clear garden
Deep-turning: For the shallow Taoyuan soil, in the 2-3 years after planting, deepen the soil by deepening the hole, squat down 10 centimeters outside the crown crown, the depth is 50-60 centimeters, and the depth under the canopy 10 -15 cm to improve the growth conditions of the root system. At the same time, combined with the application of basal fertilizer based on farm organic fertilizer.
Clear Garden: In combination with pruning, all the pests and litter on the ground, litter, fruit drop, and concentrated burning are eliminated to reduce the source of disease.
V. Pest control
Branches painted white: Peach main trunk should be painted white, prevention of pests and diseases, protection of the tree, insulation and antifreeze.
Scraping spots: Plants with flowing glue must first be scraped and then coated with the protective agent “General Tree Guard.â€
The whole garden sprays the medicine: Before spraying the garden and before the budding of the peach tree in the next year, the whole garden is sprayed with “General Tree Guardâ€, and the heat preservation and anti-freezing ensure that the flower buds will pass the winter and eliminate overwintering pests and diseases.
To enter the autumn and winter season, in order to allow the peach trees to survive winter, we must strengthen the management measures in the above aspects, give the peach tree sufficient nutrition, and ensure the strong tree vigor of the peach tree, so as to lay a good foundation for the harvest in the coming year.
