The main high-yielding cultivation techniques of crisp peach

The main high-yield cultivation techniques of crisp peach High standards to build the park. Picking trees that are heavy and boggling, and building new peach orchards, should choose land plots that have not been planted with peach trees in the past. The width of the planting trenches was widened and their depths were 60 cm and 40 cm, respectively. When backfilling, the topsoil shall be filled into the bottom of the trench, and then every 667 square meters (1 mu) shall be applied with 5000 kg of organic fertilizer and 50 kg of superphosphate uniformly, and shall be filled with subsoil. The sorghum cultivation is used. The row spacing is 3m and 4m. When planting, the root system must be well-distributed. 2. Reasonable pruning. 1 sapling shaping. Natural open heart shape, the main branch opening angle of 45 ~ 60, the first main branch from the main trunk is not less than 50 cm, one or two main branch spacing not less than 50 cm and grow on the opposite side of each other, vice main branch must be lateral branch (Backs and backs can not be used as sub-branches). Generally 2 years can be formed, which is the key to early tree entering the fruit period. 2 Reasonable pruning. In the summer, it mainly wipes back and back buds, and the lateral branches are rejected as 10-15 cm. The excess branches and buds are completely removed. After the fruit is buried, the fruit is thinned and leaves a single fruit. The distance between the fruits is 10 cm. Winter pruning is mainly to ensure the growth potential of the main branch and the sub-branch, and the remaining competing branches are cut off. 3 Apply paclobutrazol timely. Paclobutrazol can inhibit the vegetative growth of peach trees, dwarf the tree body, and increase the fruit setting rate. The application methods can be divided into root application and spraying: root application is carried out at the beginning of April. Under the canopy of the row, a shallow ditch of 20 cm is opened, and 10 g per plant is applied to the ditch: spraying should be performed immediately after physiological fruiting. The application concentration is generally 1000-1500 mg/L. The overgrowth of the tree is followed by a second half spray. 3. Pay attention to soil fertilizer management. 1 Change the soil. Peach is a shallow-rooted fruit tree. Deep-turning and soil improvement should be carried out in combination with basal fertilizer at the end of autumn. 2 fertilization. Fertilization 3 times a year: strong fruit to be applied after physiological fruit drop, mainly nitrogen, potassium fertilizer, shallow application of potassium sulfate compound fertilizer, accounting for 30% of the annual fertilizer. The appropriate amount of potassium dihydrogen phosphate was added in combination with the sprayed pesticide: the maize fruit fertilizer was applied after the fruit was harvested, mainly nitrogen, and applied shallowly with urea, which accounted for 10% of the total annual fertilizer amount; the base fertilizer was used in late October to 11 In the first half of the month, rapeseed cake and superphosphate were used for deep application after fermentation, accounting for 60% of the total amount of fertilizer used in the whole year. 3 moisture control. Peach trees are not resistant to soiling, but they also need sufficient water during the growing season (new shoot growth, fruit enlargement), and drainage and irrigation facilities should be established. In the rainy season of the south (Meiyu period), attention should be paid to drainage; from July to September it is a period of high temperature and drought, after the Meiyu period, it should be covered with a medium-thick plastic film 2 meters wide, and the soil around the membrane is tight, which not only reduces the weeds. , And effectively solve the problem of severe water shortage in high temperature and drought. 4. Strengthen pest control. The crisp peaches are mainly caused by diseases such as peach brown rot, sores (black scab), anthrax, gummy disease, peach aphid, red neck beetle, aphids and scale insects. Dong Li or Lithosulfide in the early spring is sprayed once a year. During growth and development, Dasheng M-45, thiophanate-methyl, compound carbendazim, 65% mancozeb, 50% dichlorvos, and 50% chlorbenazide are used. 50% killing lice pine emulsion and other agents (bactericidal, insecticide mixed and alternate use), spray once every 10 days, if the rain should be promptly after the spray.
