- Intervention effect Potassium fertilizer reduced soil alkali-hydrolyzable nitrogen content to varying degrees.
- Observation Soil alkali-hydrolyzable nitrogen was relatively low before leaf expansion across depths.
- Observation Soil alkali-hydrolyzable nitrogen was relatively high at blossom or fruit-set stage.
- Association Potassium fertilizer amount correlated negatively with soil alkali-hydrolyzable nitrogen at 0-20cm before leaf expansion (r = -0.8769*).
- Association Potassium fertilizer amount correlated positively with soil alkali-hydrolyzable nitrogen at 20-40 cm at fruit set (r = 0.95678*).
- Association Potassium fertilizer amount correlated negatively with soil alkali-hydrolyzable nitrogen at 40-60 cm at fruit maturation (r = -0.9835**).
- Intervention effect Applying 30 kg/667 m 2 potassium fertilizer benefited nitrogen absorption and accumulation in fruit branches before fruit set.
- Intervention effect Excess potassium fertilizer curbed nitrogen absorption by jujube plants.
- Association Fertilizer amount correlated with nitrogen content of jujube secondary branches before leaf expansion (r = 0.9823**).
- Association Fertilizer amount correlated with total nitrogen in roots (r = 0.9673*).
- Association Fertilizer amount correlated positively with nitrogen content in jujube leaves at blossom stage (r = 0.9513*).
- Association Fertilizer amount correlated positively with total nitrogen in roots at blossom stage (r = 0.9456*).
- Association Fertilizer amount correlated with total nitrogen in secondary branches at fruit set (r = 0.9455*).
