飞仙关组紫色页岩作为矿质肥源的试验

EXPERIMENT WITH THE PURPLE SHALES OF FEIXIANGUAN FORMATION OF LOWER TRIASSIC SERIES AS MINERAL FERTILIZER RESOURCES

四川盆地下三叠统飞仙关组(T_1f)紫色页岩,富含有机质、磷和多种微量元素T_1f紫色母质添加到两类基础肥力较低的紫色母质和黄壤内,种植稻麦试验后对照结果表明T_1f紫色页岩肥效显著,因此它是一种矿质肥源。

The purple shales of Feixianguan Formation of lower Triassic series(T1f) contain rich organic matter,phosphorus,and various kinds of micro element.In the lower fertility purple soils of the Shaqimiao Formation of middle Jurassic series (J2s), the Suining Formation of upper Jurassic series(J3s) ;and the lower fertility yellow soils of Ya'an Layer of Quaternary system(Qp),adding two levels of T1f parent material. 10% and 30% of the soils used,and the above lower fertility soils ware used for the control. 2. 5kg of each treament and control soils was put into each pot,repeated trebly. Wheat and rice were cultured to study the fertilizer efficiency of the purple shales of T1f as mineral fertilizer resources.The fertilizer efficiency of the purple shales of T1f is significant,that show a great future of the purple shales of T1f as the mineral fertilizer.
