荒漠土壤具有肥力较低、保水性能差的特点,而生物炭孔隙疏松、比表面积大、稳定性高难分解,常被作为改良农田土壤的材料,可能对荒漠土壤同样具有改良效果。本文选用400℃的谷壳生物炭和锯末生物炭,设置不同的生物炭施用量,采用实验室恒温培养,研究60 d后不同处理下的荒漠土壤肥力和保水能力。实验证明,添加两种生物炭的荒漠土壤肥力均有提升。其中,添加谷壳生物炭的荒漠土壤pH值随施用量的增加降低,而添加锯末生物炭的荒漠土壤pH值随施用量的增加升高;添加两种生物炭荒漠土壤的有机碳、有效P含量均呈正相关变化,其中8%谷壳生物炭表现最好,分别为4.508%、30.74 mg·kg-1;保水率随生物炭施入量增加...

The desert soil has the characteristics of low fertility,low water retention,and the biochar porosity,which is larger than the surface area,and the stability of the soil,is often used as a material to improve the soil of the farmland,and it may have a modified effect on the desert soil.this article chooses 400℃chaff biochar and sawdust biochar,set different biochar seems to use laboratory thermostatic cultivation,research under different processing after 60 d desert soil fertility and water retention.the desert soil fertility with two biochar ...
