摘要
在柴达木地区,设置无秸秆还田的常规施肥、常规施肥+不加腐熟剂秸秆还田、常规施肥+全量秸秆+"京圃园"秸秆腐熟剂2kg/667m2+尿素5kg/667m2 3个处理。进行单因素随机区组设计试验。结果表明:常规施肥+秸秆+"京圃园"秸秆腐熟剂2kg/667m2+尿素5kg/667m2与没有秸秆还田、有秸秆还田但没有施用秸秆腐熟剂相比,提升土壤有机质的效果最好,提升土壤全氮、有效磷、速效钾的效果最好,3个秸秆处理的后茬小麦籽粒产量没有显著差异。
In Qaidam area,setting conventional fertilization of no straw,conventional fertilization＋straw of no decomposing inoculants,conventional fertilization＋Straw＋＂Jingfuyuan＂decomposing inoculants 2 kg/667m2＋Urea 5 kg/667m2.Adopting single-factor randomized design.The results showed that compared with ＂Jingfuyuan＂decomposing inoculants 2 kg/667m2＋Urea 5 kg/667m2 with fertilization of no straw and without application of straw decomposition agent.The effects of increasing the soil physical and chemical property were the best.Meanwhile,the effects of increasing the total nitrogen,available phosphorus and potassium were also the best.There were no significant differences of yield of after wheat grain through above three treatments.
