研究了烧荒对土壤性质的影响。研究表明,烧荒对土壤无机氮有强烈的影响。火烧后,土壤NH4-N明显增加,第7天烧荒地比未烧荒地高出106.92%;之后又迅速降低;土壤NO3-N含量也有类似变化,烧荒导致氮素的大量流失。土壤微生物量碳也明显减少,第7天烧荒地比未烧荒地低317.153mg/kg,第32天低270.143mg/kg;之后,土壤微生物量碳恢复较快,在100天时,烧荒地比未烧荒地高出106.187mg/kg,从长期来看,烧荒对土壤微生物量有一定的刺激作用。

The effects of burning on soil properties were studied.The results show that soil inorganic nitrogen was strongly influenced by burning.After burning,NH4-N increased obviously,and the burning land(H)was 106.92% higher than unburning land(W)at the 7th day.The concentrations of soil NO3-N had similar change. Burning results to the lose of nitrogen.While,contents of soil microbial biomass carbon and nitrogen decreased obviously, soil microbial biomass carbon and nitrogen in H were 317.153 mg/kg and 67.521 mg/kg lower than W at the 7th day,respectively,and 270.143 mg/kg and (45.128) mg/kg lower at the 32th day. While, at the 100th day, soil microbial biomass carbon and nitrogen were 106.187 mg/kg and 24.258 mg/kg higher respectively.For the long-term,burning has stimulative effect on soil microbial biomass.
