Management Methods and Technical Key Points After the Persimmon Tree Fruits
Timely fertilization: When the fruit's transverse diameter reaches 4~5 cm and when the fruit size has basically become fixed, apply fruit-swelling fertilizer and pre-harvest fertilizer, mainly with quick-acting, quick-dissolving nitrogen-phosphorus-potassium fertilizer. For fruiting trees over five years old, apply 1.5~2 kg of urea and 0.75~1 kg of monopotassium phosphate per tree, or apply nitrogen-phosphorus-potassium

Key Technical Points for Winter Management of Persimmon Orchards
In winter, the management work of a persimmon orchard has three key points, namely increasing fertilizer, pruning, and cleaning the orchard. Increasing fertilizer and improving the soil. The persimmon tree is a deep-rooted tree species, and only by expanding the planting holes, improving the soil, and applying more fertilizer can the tree grow vigorously. Bearing persimmon trees should have their holes expanded and soil improved in winter, with holes 1-1.5 m long, 0.4 m wide, and 0.4-0.5 m deep. When backfilling with topsoil, apply 100-150 kg of farmyard manure per tree, or 50 kg of dried pig or cattle manure, or 100-150 kg of mushroom soil, or 1-1.5 kg of calcium magnesium phosphate fertilizer, etc., mix evenly with the topsoil, and fill it into the lower layer. Level the surface of the hole with topsoil from the orchard. Deep digging to improve the soil can also be used, that is, spreading organic fertilizer evenly at the drip line of the canopy, and then deep digging 20 cm at the fibrous root zone.
