玉米秸秆还田配施腐熟剂对土壤理化性质及玉米产量的影响

Effect of Straw Returning with Decomposition Inoculants on Soil Physical-chemical Properties and Yield of Maize

为研究玉米秸秆还田及配施腐熟剂对土壤理化性质和玉米产量的影响。在博乐市小营盘镇玉米种植区设置了3个处理的田间试验,测定土壤理化性质及土壤酶活性,并调查玉米产量。结果表明,玉米秸秆还田能增加玉米产量,增加土壤有机质、碱解氮、速效磷、速效钾,提高土壤酶活性,降低土壤容重。尤其以秸秆还田配施有机物料腐熟剂效果显著。

In order to study the effect of corn stalks returned to the field with rotten accelerant on soil physical-chemical propertiesand maize yield.A three treatment field experiments were set up in the corn growing area of the bole town in Xinjiang,through test thesoil physical and chemical properties and the soil enzyme activity,the corn yield was investigated too.The results showed that the cornstraw returned to the field could increase the yield of corn,increase the soil organic matter,effective nitrogen,available P and availableK,improve the soil enzyme activity,and reduce the weight of the soil.Especially,the effect of straw return with rotten accelerantwas remarkable.
