After entering the full fruit stage, short fruit branches and flower-like fruit branches bear fruit mainly. Dahong rose plum has strong early yield, high and stable yield. Under normal cultivation and management conditions, young trees bear fruit in two years and high yield in three years, with an average yield of 12.4kg and the highest yield of 23.7kg, equivalent to 14000 kg per hectare. Four years into the full fruit period, the highest plant yield 67.2 kg. Dahong rose plum has strong self-flowering and fruiting characteristics, so it is recommended to be planted with other excellent varieties when it is introduced into our country. Suitable matching varieties are black amber, Vikson and holy rose. Timely harvest, with the fruit surface coloring more than 85%, the top part of the fruit turned crimson as the suitable harvest time. Attention should be paid to harvesting in stages.

1. Colonization

In spring, a north-south planting ditch with a width of 1 meter and a depth of 0.8 meters was dug. When digging the ditch, the core soil and topsoil were placed respectively. At the bottom of the ditch, about 20 cm of wheat straw and corn straw were applied, 3500-4500 kg of miscellaneous fertilizer per mu and 75 kg of quick-effect special fertilizer were applied. When backfilling, the core soil was evenly filled with miscellaneous fertilizer and quick-acting fertilizer, and then the topsoil was filled, and then the seedlings were planted 3 days later, and then irrigated with small water. Then the saplings are covered with plastic bags to prevent insect pests, and the tree plates are covered with plastic film to moisturize.

2. Fertilizer and water management

At the end of May, the plant was topdressing 250 grams of diammonium phosphate, and at the beginning of August, 400 grams of potassium dihydrogen phosphate was applied to the plant. Combined with the control of diseases and insect pests, foliar spraying of 400-fold photosynthetic micro-fertilizer for 2 or 3 times. From the second year, 20 kg of farm manure was applied every year before winter, and the special fertilizer for fruit trees was applied before flowering, after falling flower, during fruit expansion period and after fruit picking in the growing season, with a total of 3 kg per plant, and irrigated once after each fertilization.

3. Shaping and pruning

The use of free spindle shape, fixed stem height of 45 cm, planting year 8: 9 except for the strong shoot center stem, the rest of the new shoots are drawn into 75-85 degrees, so that they open and grow, bend and extend; in the middle of April of the second year, the main branch leaves the outer bud light and short, the other branches are slowly put and uncut, and the over-dense branches are sparse. After 2 years, the young trees can basically form a free spindle-shaped skeleton. Pruning is mainly to thinning branches, thinning weak branches, only growing branches and competitive branches.

4. Flower and fruit management

The methods of releasing bees at flowering stage and artificial pollination were used to improve the fruit setting rate. Thinning flowers to remove late flowers, weak flowers; thinning fruit thinning to remove deformed fruit, and fruit, small fruit. There are 3-4 in the long fruit branch, 2-3 in the middle fruit branch and 1 in the short fruit branch.

5. Pest control

Before sprouting, the whole garden was sprayed with 3-5 Baomedo stone sulfur mixture, 50% fenitrothion EC was sprayed before falling flowers to kill Li Shifeng, and methyl topiramate or Dysen zinc was sprayed at the beginning of June to control plum bacterial perforation and plum red spot disease. cut off diseased fruits, diseased branches and diseased leaves in winter and destroy them centrally.
