生物炭作为无土栽培基质的初步探究
Explore of bio carbon as matrix of soilless cultivation

研究柠条深度裂解产生的生物炭作为无土栽培机制的可行性，以探讨柠条的综合开发和利用. 试验分析了生物炭和草炭复配基质的理化特性，并对小白菜做育苗期盆栽试验. 结果表明： 当草炭和柠条炭的质量比为4∶2时达到最佳配比，此时混配基质各项指标均符合理想基质的要求；柠条炭具有强大的吸附能力和丰富的孔隙结构，其作为草炭的混配基质能够较大程度提高基质的透气性和速效钾含量，有贮存和缓释养分的作用.
This experiment discussed the comprehensive development and utilization of the Caragana. In order to study the feasibility of bio carbon which was produced by the dissociation of Caragana as soilless cultivation，the experiment analysed the physicochemical properties of biochar and compound matrix，and also maked pot experiment for pakchoi in seedling stage. The result showed while Caragana carbon mixed peat carbon with 4 to 2，the indicators all reached the requirement of ideal matrix. Caragana carbon had strong absorption capability and abundant pore structure. Furthermore，Caragana carbon as the mixed matrix，which can greatly improve the permeability and available potassium content，had great effect on storaging and releasing nutrients slowly
