厌氧消化残留物对改良土壤的作用

Effects of methane fermentation residues on soil improvement

张无敌,周长平,刘士清。厌氧消化残留物对改良土壤的作用。1996,4(3):35～37。 厌氧消化残留物作肥料,有利于粪便秸秆还田,既可作为优质肥料,又是土壤改良剂。厌氧消化残留物具有改善土壤理化性状、促进土壤团粒结构形成以及激活土壤微量元素和微生物活动等特点。厌氧消化残留物的肥效和培肥地力的功效,能使农作物平均增产10％～30％。

It helps stalks to return to field when the residues from methane fermentation are used as fertilizers.The residues are not only high quality fertilizers,but also can improve soil.The functions of the residues in improving soil physi-chemical properties and granular structures, activating microelements and micro-organisms in soil can increase crop production by 10 to 30%.
