Answer: The persimmon tree should be fertilized according to the age before the soil is frozen. Saplings applied 2.5 to 3 kilograms of organic fertilizer per plant, applied a ring-shaped groove, and watered easily after application. In mountainous areas where there is no watering condition, snow or ice blocks can be deposited in the tree nests to meet the water requirement of the persimmon trees. During the growing season, the appropriate amount of Epnophycocyanin can be sprayed to supplement the nutrition of the persimmon tree, promote the growth, prevent and treat premature senescence, and attack the senescent persimmon tree to extend its life span.
