Abstract：The “3414” design was used to study the nutrient absorption characteristics and the optimum fertilization amount and method for mulched Jinxiang garlic .The results showed that during the growth of Jinx-iang garlic , the absorption of nitrogen was the most , and then potassium and phosphorus .The absorption ratio of nitrogen, phosphorus and potassium was 1∶0.36∶0.70.The absorption peaks of nitrogen and potassium were both in the bulbing period , and the phosphorus absorption peak was in the garlic sprout elongation peri-od .The application of nitrogen , phosphorus and potassium all could increase the garlic yield , and the optimal fertilization amounts were 436.95 kg/hm2 of N, 213.34 kg/hm2 of P2O5, and 336.74 kg/hm2 of K2O.The best fertilization method of both nitrogen and potassium was 2/3 as base fertilizer and 1/3 for topdressing .
