In the past two years, the peach planting efficiency was relatively high. Many farmers have successively developed peach planting. However, the technical management of new growers is relatively lacking. In order to help them do a good job in the spring management of the newly planted peach trees, this article was written for reference.
1. Spring shears. Peach trees that are not cut in winter are trimmed. The newly planted peach trees are mainly cultured trees, with the emphasis on cultivating the two main branches and setting the height to 60 to 80 cm. Select two branches with good growth potential, full shoot buds, and positive direction as the two main branches, and fix the angle of the main branch into 45 to 50 angles through branching, pulling, and falling. There are six details to emphasize when trimming: (1) Extend the branch treatment. The weak branches are short and heavy, and the moderate tree branches and strong Wang branches are thrown away. (2) Treatment of branches near the branches. Remove competition branches, leggy branches, and dense branches. (3) Correct the direction of the branches. Branches are not in the right direction and can be replaced with promising neighboring branches. (4) The growth of the two main branches. Requires two main branches grow in balance, the main branch tree strong, can leave weak branches for head, leaving more fruit; the main branch of the tree is weak, can stay strong branches for the first time, leaving little fruit. (5) Leave a branch on the main branch. As a result, the branches are arranged on the main branch in a cross-wise manner, and the same side results in a branch distance of 15-30 cm. (6) According to the density of the leaves, leave the result of the branch. The plant spacing of 1 to 2.5 meters does not leave large-scale branch groups, and the plant spacing of 2.5 to 3 meters does not allow large-scale branch groups (the distance of the same side branch group is not less than 40 centimeters).
2. Completely clean the garden. Remove dead branches, fallen leaves, weeds, and branches cut off during the winter. This is conducive to underground management, including top-dressing, watering, ploughing, etc. It is also helpful to remove some overwintering pests hidden in litter.
3. Pour frozen water. The thawing water is poured before budding, especially in the mountain orchards and sand orchards that have not been frozen. In winter, the orchard with lighter branches has been cut, and the orchard has been seriously plucked. This is conducive to uniform budding, flowering and high fruit setting rate.
4. Reasonable fertilization. There is no plot of organic fertilizer in the fall and it must be filled in spring. At the beginning of April, 2000-3000 kg of high-quality rot fertilizer was applied per acre, and the application of ditch and hole was better than that of ground spreading. After the young fruit expansion period, the chemical fertilizer was applied again, and ammonium ammonium bicarbonate 40 to 60 kg and potassium sulfate 10 to 20 kg were applied.
5. Apply a protective agent to the saw cut. The large swarf cuts are not easily healed and are prone to diseases caused by pests and infestations. They should be applied with protective Pharmacy such as Zhifuling, 9281 and Guotukang.
6. Prevent late spring. In the budding stage, spraying more than 6000 times of love or Bi defended 800 ~ 1000 times liquid, can effectively prevent cold. Throughout the flowering period, we must pay close attention to the weather forecast, attach great importance to the frosty blue warning, and timely smoke and cold at night. After the frost had sprayed 6000 times again, the love was over.
