秸秆还田秸秆还田straw manure秸秆还田(straw manure)又称秸秆直接还田肥。指前茬作物收获后，把作物秸秆直接用作后茬作物的基肥或硬盖肥。农作物的秸秆是重要的有机肥源之一，秸秆还田是物质循环和再利用的良好形式.各个国家和地区利用秸秆的方法不相同，但传统的利用方式多是利用秸秆垫圈.制成厩肥、沤肥、堆肥、用作沼气肥原料，或直接烧成草木灰。自20世纪40年代以来，在美国出现免耕或少耕耕作法之后，秸秆搜盖地面或直接翻入土壤中以保持水土和培肥土壤的秸秆还田肥日益受到许多国家的重视。日本南方约62%的稻草直接还田，中国北方多利用大豆、玉米、高粱、麦子的根茬(或秸秆)直接还田，南方则以稻草直接还田为主.成分及肥效作物的秸秆及残体的有机组成成分主要是纤维素、半纤维素、木质素，而蛋白质、醉溶性物质及水溶性物质等的含量相对较少。一般作物秸秆中钾、钙、硅等矿物质含量较高，其次是氮、磷。但作物种类不同，其秸秆所含的养分及组成也有所不同，通常豆科作物和油菜的秸秆含氮较多，禾本科作物的秸秆含钾较多。几种作物秸秆的主要化学组成及养分含量见表1.物秸秆类型不同，作物增产的幅度也有差异，增产率多在10%~15%之间，几种直接还田秸秆类型对作物增产率见表2。英国洛桑试验站连续(1934~1951)，对秸秆直接还田与等量桔秆经堆腐后还田的比较试验表明，直接还田的马铃拼产t比堆腐后还田的每公顷高3.5吨，糖用甜菜高O，52吨，大麦籽提高0 .41吨。表2几种直接还田桔杆类型及作物的增产率┌─────────────┬──────┬─────┐│还田材料及用t │平均增产幅度│平均增产率││ (kg/hmZ)│(%) │(%)│├─────────────┼──────┼─────┤│麦秸(或糠)类:1 500~4 500 │3 .2~60.3│14.8士1.6 ││玉米枯类:375~15 000│一2 .9~54.6 │13.0士1.6 ││稻草类:4 500~7 500│0 .3~75.1│13.2+2。
