摘要
[目的]研究沼液改良煤矸石地对樱桃栽培地土壤物理性状、化学性状和生物学性状的影响.[方法]以樱桃树为试验材料,采用完全随机设计,研究沼液改良煤矸地对樱桃栽培地土壤物理性状、化学性状的影响.[结果]施用沼液的处理能使樱桃树正常生长,A4(1 200 mL/m2)沼液处理降低了土壤容重,孔隙度有所增加,脲酶活性、过氧化氢酶活性、速效氮、速效磷、速效钾、全氮、有机质含量均显著提高,A3 (900 mL/m2)沼液处理后土壤pH下降最多.[结论]A4(1 200 mL/m2)沼液改良煤矸地后土壤各项指标均较好.
Abstract
[Objective] To study effect of biogas slurry modified coal gangue on soil properties of cherry cultivation land.[Method] Effects of biogas slurry on soil physical,chemical and biological properties before and after cherry cultivation under the condition of completely random design were studied with cherry tree as experimental material.[Result] Application of biogas slurry could make cherry trees grow normally.The treatment of biogas slurry (A4 1 200 mL/m2) could decrease the soil bulk density,porosity,urease activity,catalase activity,the alkaline solution nitrogen,available phosphorus,available potassium,total nitrogen and organic matter contents were significantly improved,and the soil pH was well mitigated by (A3 900 mL/m2) biogas slurry.[Couclusion]The effect of A4(1 200 mL/m2) biogas slurry is better.
