Cultivation of peach-shaped plum with rare fruit

Peach-shaped plum is a small deciduous tree of Rosaceae, flowering from late March to early and mid-April. The fruit performance of this variety is very good, long fruit branch, middle fruit branch, short fruit branch and flower bouquet fruit branch can bear fruit, and have cluster fruit phenomenon. The fruit ripens from late July to early August and has a good seasonal consumer market. Peach-shaped plums are resistant to drought and cold, and are not strict with the soil. They can be planted wherever they are suitable for cultivation of peaches and plums.

Choose the garden and choose the place with drainage and irrigation conditions to build the orchard. If planted in the mountains, the slope should be less than 25 °, the whole reclamation depth should be 20 to 25 cm, and the slopes with larger slopes should be made into horizontal terraces. The row spacing of planting plants in mountainous area is 2.5 × 5 meters, and that in plain area is 3 × 4 meters. Apply 100 to 150 kilograms of soil and miscellaneous fertilizer in the cave before planting.

Timely planting in winter should be carried out after the defoliation of seedlings, the best time is from late December to mid-January of the following year, and spring planting can be carried out from February to March. Dry 35 to 40 cm, stretch the roots of the seedlings and put them into the pit, fill the soil tightly, and pour the planting water.

Four to five branches were selected as the main branches in the trunk in the summer of the first year after the young trees were planted, and the rest were removed. There should be a certain distance between the main branches, showing a radial distribution. Before sprouting in the second year, each main branch should be cut short by 50 to 60 centimeters, and the cutting buds should be outward. After coming out of the shoot, let the extension branch grow on the lower side of the top of the main branch. Before sprouting in the spring of the third year, the elongated branches of the main branches were cut short according to the growth situation, so that their power was balanced. Pay attention to erase the tillering seedlings at the base of the trunk at any time, and remove the buds in the second and third spring so as not to consume nutrients. Before putting into production, young trees are fertilized once every year when sprouting and spreading leaves in spring and falling leaves in autumn.

In order to regulate the vegetative growth and promote the balance of fruit, the one-year-old branches of the put-into-production tree management should be shortened and thinned. Short fruit branches and bouquet-like fruiting branches should be properly removed to ensure normal branching and fruiting of the plant. It is required to apply pre-flowering fertilizer, strong fruit fertilizer, pre-fruit fertilizer and pre-winter fertilizer. It is best to use 0.2% to 0.3% potassium dihydrogen phosphate as foliar topdressing in June, spraying every 12 to 15 days. In the aspect of pest control, we should pay attention to longicorn beetles, heart-eating beetles, beetles, bugs, aphids, termites and other pests.
