摘要
曲靖市茨营乡茨营—蔡家冲一带分布着下第三系蔡家冲组的中—碱性凝灰岩 ,厚2 1— 2 4m ,分布面积 69 75× 10 4 m2 ,其含沸石 5 8% ,蒙脱石 10 68% ,ω (K2 O) =3 71% ,稀土总量ω (REO) =0 0 34 %。具吸附性、吸水性、膨胀性及阳离子交换性能 ,是一种新型的农用岩石。储量 3141× 10 4 t。笔者对其理化性质进行了详细研究 ,为该凝灰岩改土肥田的机制提供了理论依据 ,又通过对该凝灰岩的可利用的元素激活、释放原理及化工工艺的研究 ,开发形成了系列的该凝灰岩为载体的复混 (合 )肥。在烟草、蚕桑、土豆、水稻、玉米五种作物多组试验、示范 。
In the CiyingCaijiachong region of Qujing, there is the intermediatealkaline tuff of Palaeogene Caijiachong Formation, with thickness 21 24m, distribution area 69 75×10 4m 2, which consists of zeolite 5 8%, montmorillonite 10 68%, w(K 2O)=3 71%, total REE w=0 034%. It is a new rock in agriculture application, with adsorptivity, water absorbability, expansion and anion exchange ability, reserves 3 4×10 4t. We have studied the physical and chemical nature of it in detail and provided a theoretical basis of the mechanism in applying it to reforming soil and fertilizing field. And we have developed a series of composite fertilizer with it as a container material according to a study on the activization and release principle of its available elements and the chemical technology. Many experiments for tobacoo, mulberry, potato, rice and maize have proved that this tuff composite fertilizer series is better than others with the same nutrient composition.
