摘要: 彭阳县南部山区茹河流域的川、塬、台地,土壤有效磷丰缺指标中等偏下,速效钾丰缺指标中等偏上,相对产量为90%有效磷含量为24.5mg/kg,速效钾含量为146.6mg/kg;产量水平600kg/667m^2左右时,建议P2O5施用量为8-10kg/667m^2,K2O施用量为0-4kg/667m^2。

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.
