Abstract: The topography of Southern mountains RuHe basin is plain, tableland and platform, abundance and lack of available p in soil indicators is below average, but rapidly-available potassium abundant and lack index above average content is 146.6 mg/kg and production levels of about 600 kg/667m2, rapidly-available potassium is 24.5 mg/kg with relative yield 90%, it is suggested that applying P20s content of 8 - 10 kg/667m2, and K20 content of 0 - 4 kg/667m2.
