本文报道了植物动力2003 中的微量元素、稀土元素的成分和含量,研究了在恒温条件下,植物动力2003 对北京褐土表土、生土、东北黑土和广东红壤中微量元素和土壤pH 值随培养时间的变化。结果表明:PP2003 原液中含有多种元素。其中主要有中量元素硫和微量元素锌,其含量分别为16180mg/L 和12550mg/L。施用PP2003 后可以提高土壤的缓冲能力,使土壤pH 值变化缓慢,保持相对稳定。对土壤中交换态微量元素含量变化的影响则随土壤类型不同而异。
In this paper, the composition and content of trace elements and rare earth elements in plant dynamics 2003 were reported. The effects of plant dynamics 2003 on the trace elements and soil pH of topsoil, raw soil, black soil of Northeast China and red soil of Guangdong Province Changes in culture time. The results show that: PP2003 stock solution contains a variety of elements. Among them, there are mainly middle-element sulfur and trace element zinc, whose contents are respectively 16180mg / L and 12550mg / L. Application PP2003 can improve the soil buffer capacity, soil pH changes slowly, remain relatively stable. The effect on the change of exchangeable trace elements content in soil varies with soil types.
