How to plant crisp persimmons and how to plant crisp persimmon trees

1, timely sowing. Crispy persimmon is a deciduous fruit tree, which needs to be planted after defoliation and before germination. The most suitable period is after defoliation in autumn and before germination in spring, that is, before mid-February, which generally does not exceed the rain solar term. Planting density depends on topography, soil, variety, rootstock and cultivation management conditions. The row spacing of astringent persimmon plants in mountainous areas is 5m× 6m or 6m× 6m, and that of sweet persimmon plants is 4m× 5m or 5m×5m；. The row spacing of flat persimmon plants is 6 m× 7 m or 7 m× 7 m, and that of sweet persimmon plants is 5 m× 6 m or 6 m× 6 m. The standard for opening holes is 70 cm deep and 70 cm wide.

2. Trim the branches. Adult trees with tall crowns or shady branches should be moderately retracted and pruned after defoliation in winter.

Prune mainly short branches, combine thinning and shrinkage, cut off dense branches, cross branches, clustered branches and diseased dead branches, promote the rational distribution of branches, and cut them into reasonable tree potential. Increase fertilizer and improve soil. Persimmon is a deep-rooted tree species. It needs to expand holes, improve soil and increase fertilizer to make the tree grow vigorously.

3. Strengthen fertilizer and water management. Persimmon trees have strong moisture tolerance and weak drought tolerance. Too dry soil can easily lead to poor growth and poor results. When the soil moisture content is 30% ~ 40%, the new shoots grow best. Orchard soil management should pay attention to improving soil permeability and water retention. The specific measures are: after planting, spray the roots with enough water, and then spray them every 3-5 days (or extend the watering interval appropriately) until the fruit seedlings survive. The most needed fertilizer for persimmon trees is nitrogen fertilizer, followed by phosphorus fertilizer and potassium fertilizer.

4. Clean the garden in winter. Winter pruning should thoroughly remove diseased fruits, diseased stems, dead branches and fallen leaves, and remove the source of overwintering pests and diseases.

5. Grafting propagation is generally adopted. The northern persimmon producing area takes Junqianzi (commonly known as black jujube) as the rootstock. After the ripe fruit becomes soft, it is rubbed and washed to remove the pulp for later use.
