Abstract: In order to get the formation about the content of alkali-hydrolyzable nitrogen in soil, available phosphorus and available potassium, and the input of chemical fertilizer in apple orchard, we survey 25 peasant households' input of chemical fertilizer in apple orchard, and collect soil samples for measuring and analysis. The results show that the average input of nitrogen, phosphorus and potassium nutrient is 839.6 kg / hm2, 520.4 kg / hm2, and 899 .7 kg / hm2, respectively; the input proportion of nitrogen to phosphorus to potassium nutrient is 1：0.62：1.07; in 0-60cm soil, the average content of alkali-hydrolyzable nitrogen is 53.49 mg/kg, the average content of available phosphorus in soil is 70.73 kg /mg, and the average content of available potassium in soil is 180.1 mg/kg (the proportion of alkali-hydrolyzable nitrogen to available phosphorus to available potassium in soil is 1: 1.32: 3.37). It indicates that the overall level of input of chemical fertilizer in apple orchard is relatively high; the content of alkali-hydrolyzable nitrogen in soil is very low on the whole, the content of available phosphorus in soil is very high, and the content of available potassium in soil is high.
