摘  要:
为探索宁夏乌拉尔甘草人工栽培的合理施磷量,对宁夏中部干旱带栽培的乌拉尔甘草进行了不同施磷量对其产量和经济效益影响的研究。结果表明:土壤施磷量和甘草产量存在显著的曲线相关,随着施磷量的增加产量显著增加,当施纯P2O5达到155kg/hm2时,产量达最高,为6 927.75kg/hm2;继续增加施磷量,甘草增产不显著。施纯P2O5量在75~150kg/hm2时,达最佳经济效益。

摘  要:
To explore the rational phosphorus levels of Ningxia Ural licorice under artificial cultivation condition,different phosphorus application rate on yield and economic impact in central drought areas of Ningxia Ural licorice were studied.The results showed that there was a significantly linear correlation between soil phosphorus content and licorice production,and with the increase of phosphate level,the production of licorice increasing significant.When P2O5reached 155kg/hm2,the production reached the highest 6 927.75kg/hm2,the Phosphate levels continue to increase,the production of licorice increased was not significantly.The best economic benefits could be achieved when the P2O5content was 75~150kg/hm2.
