Abstract

为确定干旱区生物炭的合理施用量及其对土壤水文过程的影响,采用室内土柱试
验,研究了3 种生物炭添加量( 5%、10%和15%) 和4 种生物炭类型( d < 0. 25 mm 竹炭、
0.25 mm<d<1 mm 竹炭、d<0.25 mm 木炭和0.25 mm <d<1 mm 木炭; d 为粒径) 对地下水补给、
土壤持水能力、土壤水分上升运动和蒸发的影响.结果表明: 生物炭对地下水补给、土壤持水
能力、土壤水分上升运动和蒸发都有明显影响,但生物炭原料和粒径不同,其影响效果不同;
随生物炭施加量的升高,地下水对土壤补给量增大; 添加生物炭可提高土壤持水能力,促进土
壤水含量的上升速度,其中,添加竹炭效果大于木炭,小粒径生物炭大于大粒径生物炭; 生物
炭添加量较低( 5%) 时能有效抑制土壤蒸发,但添加量过高则可能促进土壤蒸发.干旱地区土
壤适当施用生物炭可提高土壤保墒能力.

Other Abstract

In order to determine the rational amount of biochar application and its effect on soil
hydrological processes in arid area,soil column experiments were conducted in the laboratory using
three biochar additions ( 5%,10% and 15%) and four different biochar types ( d<0.25 mm bamboo
charcoal,0.25 mm <d<1 mm bamboo charcoal,d<0.25 mm wood charcoal and 0.25 mm <d<1 mm
wood charcoal; d is particle size) to study their impact on the phreatic water recharge,soil waterholding
capacity,capillary water upward movement and soil evaporation. The results showed that the
addition of biochar could change the phreatic water recharge,soil water-holding capacity,capillary
water upward movement and soil evaporation obviously. But the effects were different depending on
the type of biochar raw material and the size of particle. The phreatic water recharge increased with
the increasing amount of biochar addition. The addition of biochar could obviously enlarge the soil
water-holding capacity and promote the capillary water upward movement rate. This effect was greater
when using the material of bamboo charcoal compared with using wood charcoal,while biochar
with small particle size had greater impact than that with big particle size. The biochar could effectively
restrain the soil evaporation at a low addition amount ( 5%) . But it definitely promoted the
soil evaporation if the addition amount was very high. In arid area,biochar addition in appropriate
amount could improve soil water retention capacity.
