Garden jujube trees can be applied with excrement.

Yes, but the fertilizer must be fermented before use. Direct fertilization has germs, and the heat generated by the fermentation of manure at the root of trees will burn seedlings. Fertilization method is: dig a circle around the seedlings, apply fermented fertilizer, cover the soil and water, dig another circle outside this circle next year, and then fertilize. The fruit produced by applying farmyard manure is sweet and delicious, and the soil is not easy to harden. Young trees should be fertilized less.
