The results showed that compared with the farmer’s practice model (chemical 2 N-P O -K O: 274.2-345-0 kg/hm ), the normal chemical fertilizer + organic fertilizer model 2 5 2 2 2 (chemical N-P O -K O: 278.4-98.55-180 kg/hm , organic fertilizer 3600 kg/hm ) reduced the wa- 2 5 2 ter-soluble salt content of seedl
