By adopting a series of dwarfing and close planting measures, pomegranate can blossom a little in the second year, with the output of 4 15kg in the third year and 7 18kg in the fourth year, which is 1.3 times higher than that of traditional cultivation. The cultivation techniques of pomegranate dwarf and close planting are introduced as follows:

Soil preparation and colonization of pomegranate planting

According to the site conditions, management level and the growth characteristics of pomegranate trees, the plant spacing of 2 m× 3 m was selected for planting. Deep ploughing and soil improvement before planting. Digging fish scale pits on steep slopes; Build gentle slope and reverse slope terraces with a width of 2-3 meters. When planting, dig a pit of 1 m3 along the inside of the terrace, and apply 5000 kg of soil miscellaneous fertilizer or 60-80 kg of compound fertilizer per mu. When the soil moisture is good in spring, plant it. After planting, be practical, water the roots, and then cover the tree tray with plastic film.

In arid and barren mountainous areas, the trunk with a height of 5- 10 cm can be reserved and cut off for planting to prevent water evaporation and ensure the survival rate.

Pomegranate planting promotes the rapid growth and formation of young trees

1, plastic trimming.

After planting the seedlings, leave a trunk in the hole and make it evacuation layered. 1 layer, the main branch is 30 cm away from the ground, all the branches and buds below the plastic belt are thinned out, and the overgrown branches sprouted in the rhizosphere are thinned out in time, and the main branch angle is set at 50-70 degrees. Proper drainage of vertical branches, overlapping branches and thin drooping branches in the tree cavity will make the tree short and compact, and the branches will be evenly distributed, so as to achieve the purpose of ventilation, light transmission and three-dimensional fruit.

2. Strengthen fertilizer and water management.

Plant it in the base when raising seedlings. In places where it is not convenient to apply base fertilizer, 0.3%-0.5% urea solution can be sprayed outside the roots for a long time after planting, once every 10- 15 days and continuously for 2-3 times. In autumn and winter, an annular ditch of 30-50 cm is dug along the periphery of the trunk at 1 m, filled with straw and weeds, and then the soil is sealed and leveled to improve the soil and increase the soil organic matter content.

3, intertillage weeding, reasonable intercropping.

Before freezing, after thawing and during the growing season, the orchard should be shallowly planed 10-20cm, 3-5 times a year, to keep the soil surface loose and free of weeds. Low-stalk crops such as peanuts, sweet potatoes and melons can also be intercropped among fruit trees, so as to achieve the purpose of moisturizing and grass prevention on the surface, short growth and high income.
