Fertilization Management of Young Jujube

The jujube tree was planted in that year, the basic fertilizer was applied at the bottom of the hole, and the topdressing was applied under the crown after slow seedling. After the second year, fertilizer was applied twice a year. For the first time before sprouting, dig a 20cm ditch around the crown and apply soil fertilizer and half of the chemical fertilizer used throughout the year. The second time, in mid-July, more points under the crown to apply the other half of chemical fertilizer, a depth of 10 centimeters. After leaf spreading, 0.5% to 0.3% potassium dihydrogen phosphate was sprayed on branches and leaves for extra-root topdressing with an interval of 20 to 30 days each time.
