Statistics of fertilization in Lishu County was collected and analyzed in the paper.The results showed that after soil survey in 1982,soil organic matter content,nitrogen content,available phosphorus,available potassium were increased.Fertilization technology according to the main types of soil in Lishu come to effect fertilization and yield equations.In black soil district the fertilization of N-P₂O₅-K₂O was 13.26-5.46-5.64 kg/667 m²,the highest yield was 644.7 kg;in north-west sandy soil areas the fertilization of N-P₂O₅-K₂O was 13.26-4.57-7.91 kg/667 m²,the highest yield was 582.5 kg;in the southern brown soil zone the fertilization of N-P₂O₅-K₂O was 12.4-8.33-4.08 kg/667 m²,for maximum yield was 699.58 kg.When the county was accounting as a whole,the fertilization of pure N14.38kg,P₂O₅ 5.28kg,K₂O 6.43kg,the maximum yield was 637.14 kg.In main grain production areas of Lishu,input of 1 kg fertilizer achieved 9.27 kg increase of grains.Fertilizers contribution rate to yield increase decreased in such order: nitrogen＞ fertilizer＞ K.According to different types of areas,yield increase by fertilizer application in such order: wind sand soil area in the north ＞ brown soil zone in the south ＞ black soil area in the central.
