| 摘 要： | 通过盆栽试验研究了3种菜园土壤(高磷、中磷和低磷土壤)与4种不同水平磷肥配施对生菜产量及土壤中不同浸提形态磷素的吸收转化率的影响。结果表明,菜园土磷素含量对生菜产量的影响依次为高磷土>中磷土>低磷土,且以高、中磷土配施中水平磷肥以及低磷土配施高水平磷肥可使生菜显著增产;不同磷素含量菜园土对磷素的吸收转化率的影响依次为中磷土>低磷土>高磷土,且以高磷土不施磷或施低水平磷、中磷土不施磷或施中水平磷、低磷土施高水平磷可使磷素吸收转化率显著提高;不同浸提形态磷素的吸收转化率以中磷土NaHCO3和H2O、低磷土H2O和NaOH、高磷土NaHCO3和NaOH表现较高。

| Abstract: | By selecting three vegetable garden soils of high,middle and low phosphorus and four levels of P use,we studied on their impact on lettuce yield and different extract morphological phosphorus absorption and transition.The result showed that the impact degree rank on P use of lettuce is high phosphorus soil>middle>low phosphorus soil.High and middle phosphorus soils applied with middle level phosphorus;low phosphorus soil applied with high level phosphorus could significantly improve the yield.The impact deg... |
