摘要
为了解有机物料腐熟剂对秸秆的腐解效果及对作物产量的影响,采用田间调查和室内分析的方法,研究了有机物料腐熟剂对黏质潮土土壤理化性质、玉米秸秆腐熟程度、小麦产量及其构成因素的影响。结果表明,施加有机物料腐熟剂30 kg/hm2能够降低土壤容重和p H值,增加土壤养分含量,增加小麦穗长和穗粒数,显著提高小麦产量,较秸秆还田不施加有机物料腐熟剂处理增产3.02%。
In order to understand the effect of organic matter-decomposing inoculant on decomposition of stalk and corp yield,using field survey and indoor analysis,a field experiment was conducted to study the effects of organic matter-decomposing inoculant on soil physico-chemical properties,decomposition level of corn stalk and wheat yield in clay soil.The results showed that the application of organic matter-decompo-sing inoculant of 30 kg/ha reduced soil bulk density and pH value,increased soil nutrient content,wheat ear length and grain number per ear, thereby significantly improved wheat yield, which increased by 3.02%compared with the treatment without organic matter-decomposing inoculant.
