Abstract: In order to promote the fertilization and improvement of albic soil,the cultivated land with different yield levels in albic soil area was selected,and 11 soil physical and chemical indexes were measured and evaluated by principal component analysis.The results showed that the cumulative contribution rate of the three principal components extracted by principal component analysis was up to 80.900%.The three principal component scores were further clustered,and the soil fertility were divided into two categories.The scores ranged from -0.83≥F≥2.11 and -1.97≥F≥-1.53.The fertility of albic soil was mainly determined by the chemical properties of the soil.Albic soil was rich in potassium.Therefore,it was suggested to enhance the fertilization and soil nutrient management of albic soil field by application organic fertilizer in combination with inorganic fertilize,and reducing the potassium fertilize.This method can objectively evaluate the quality of cultivated land in albic soil area.
