Name: Bone charcoal powder
Introduction: A kind of amorphous carbon, carbon containing 7% ~ 11%, about 80% of the calcium phosphate, and other inorganic defatted bone under the condition of the air through a degreasing, degumming, high temperature calcination, sorting process carbide.
Application: Bone charcoal powder on the effects of heavy metals on the one hand the bone charcoal itself is a kind of alkaline substances can increase the soil pH, makes the soil heavy metals in the form of carbonate formation of precipitation, on the other hand bone charcoal powder, organic matter content is higher, can increase the number of soil heavy metal organic combination mode.

名称(míngchēng)：
硅肥
具有硅(Si)标明量的肥料(féiliào)，属于一种中量元素肥料(féiliào)，属碱性物质。
简介(jiǎn jiè)：
用途：
硅肥能显著增加土壤有效硅的含量，与重金属结合成硅酸盐化合物从而增加残渣态重金属的相对含量；同时硅可缓解重金属对植物生理代谢的毒害，提高根系活力和抗性，抑制重金属向上运输和转移。

名称(míngchēng)：
沸石
是一种含水的碱金属和碱土金属的架状铝硅酸盐矿物，由通过(tōngguò)共用氧连结在一起的硅氧四面体和铝氧四面体三维格架组成，具有疏松、多孔的结构，白度极高。
简介(jiǎn jiè)：
用途：
天然沸石具有较强的选择吸附性能、离子交换性能和较大的吸附容量，在改良土壤方面有独特的作用。有研究表明，沸石配以骨炭施入土壤中可有效降低土壤有效态重金属含量，使轻度污染土壤上的蔬菜达到卫生安全标准。
