文档介绍

文档介绍:名称:
骨炭粉
一种无定形碳,含7%~11%的碳、约80%的磷酸钙和其他无机盐。由脱脂骨头在隔绝空气的条件下经脱脂、脱胶、高温灼烧、分拣等多道工序碳化制得。
简介:
用途:
骨炭粉对重金属的固定效果一方面在于骨炭本身是一种碱性物质可以增加土壤pH,使得土壤重金属以碳酸盐的形式形成沉淀,另一方面骨炭粉的有机物含量比较高,可以增加土壤重金属有机结合态的数量。
Name: Bone charcoal powder
Introduction: A kind of amorphous carbon, carbon containing 7% ~ 11%, about 80% of the calcium phosphate, and other anic 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 bination mode.
名称:
硅肥
具有硅(Si)标明量的肥料,属于一种中量元素肥料,属碱性物质。
简介:
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。
Name: silicon fertilizer
Introduction: With silicon (Si) indicating the amount of fertilizer, belongs to a volume element in the fertilizer, alkaline substances.
Application: Silicon fertilizer could significantly increase the content of soil effective bined with heavy metals into the pound to increase the relative content of heavy metal residue state;At the same time, silicon can alleviate the heavy metal poisoning plant physiological metabolism, improve root activity and resistance, restrain upward transportation and transfer of heavy metals.
名称:
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:
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。
Name: zeolite
Introduction: a kind of aqueous alkali metal and alkaline earth metal frame shape aluminum silicate minerals, by oxygen linked together by sharing the silicon oxygen tetrahedron and alumina tetrahedron three-dimensional framework, with a loose and
