It looks like a persimmon, but its shape is a bit long. What kind of plant is this?

Pallet management of persimmon trees

Deeply turn the tree tray twice a year, 1 in March-April in spring, and the second time is after the fruit is harvested and before freezing. The deep turning range is from the trunk to the edge of the crown, slightly shallow near the trunk, and gradually deepened outward to prevent root injury. Covering with grass under the tree tray is an effective way to improve soil nutrients and water conditions, and it is one of the important measures for persimmon trees to achieve high yield and high quality. Apply appropriate amount of nitrogen and potassium fertilizer before covering grass, then water and cover grass. The suitable thickness of grass mulch is 15-20cm, and the coverage range is within the tree crown, but there is no grass mulch 30cm away from the trunk in Fiona Fang. After covering the grass, sprinkle some soil and press the grass bit by bit to prevent wind and fire.

Fertilization management of persimmon trees

The suitable time for applying base fertilizer to persimmon trees in autumn is from the middle and late September to1early October 10. The fertilization method is to apply it in a strip ditch or annular ditch, dig a strip ditch or annular ditch with a width of 50 cm and a depth of 60 cm along the outer edge of the crown, put the topsoil and undecomposed crop stalks into the bottom of the ditch, and mix the decomposed soil miscellaneous fertilizer with the March seed fertilizer and apply it in a soil layer of 20-30 cm. No matter which fertilization method is adopted, the decomposed farm manure and special fertilizer should not be applied too deeply, so as not to affect the fertilizer efficiency.
