摘要
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。
The present paper analyzed the composition and concentration of nutrients and rare earth elements in Plant Power 2003(PP2003).Effects of PP2003 on the changes of nutrient concentration and rare earth element in drab soil,black and red soil varied with the culturing time.The results showed that PP2003 contained many nutrients but sulphur and zinc were the main elements with the concentration of 16180mg/L and 12550mg/L,respectively.Buffering compancity of soil could be improved by using PP2003,and the effect on available nutrient in soil varied with soil types.
