| 摘 要： | 采用Bowman和Cole提出的有机磷分级体系,分3个灌水量对外源活性有机磷β-甘油磷酸钠在黄棕壤中的淋溶和转化特征进行了研究。结果表明,大于50mm的灌水量可以使β-甘油磷酸钠发生淋溶。施入黄棕壤中的β-甘油磷酸钠在24h内可以转化为速效磷和中活性有机磷,灌水量愈大,速效磷和中活性有机磷积累的土层也愈深。中稳性有机磷和高稳性有机磷含量没有明显变化。

| Abstract: | The leaching and transformation of β-Sodium glycerophosphate in Yellow-brown earths were studied with Bowman-Cole method under 3 different irrigation norms.The results showed that β-Sodium glycerophosphate could transfer to Olsen P and moderately labile organic P in 24 hours.The accumulation depth of Olsen P and moderately labile organic P increased when irrigation rate was up.The contents of moderately resistant organic P and highly resistant organic P in soil layers had no significant change between treatments. |
