摘要
在大田条件下,研究了BM秸秆腐熟剂对还田玉米秸秆腐熟程度和小麦生长发育及产量的影响,结果表明:施用BM秸秆腐熟剂与不施用BM秸秆腐熟剂相比,还田秸秆提早30d腐熟,且小麦植株生长健壮,分蘖多,千粒重提高。最佳处理方法是在施用配方肥的基础上(525kg/hm2)进行秸秆还田并加施BM秸秆腐熟剂30kg/hm2,与在习惯性施肥基础上(底施磷酸二铵375kg/hm2)不施用BM秸秆腐熟剂相比,可使农田秸秆提早55d腐熟,小麦生长健壮,分蘖多增产1667.5kg/hm2,增幅19.7%。
In order to research the effect of BM straw decomposition inoculant on fermentation of smashed corn stalk and wheat production,an experiment with 5 treatments was conducted.The results showed that application of BM straw decomposition inoculant to smashed corn stalk shortened the decomposition term by 30 days.Additionally,wheat plants grew strongly,with more tillers and increasing grain weights.The best treatment was applying BM straw decomposition inoculant of 30kg/ha to smashed corn stalk on the base of formula fertilizer（525kg/ha）,which could shorten the decomposition term by 55 days,and increase wheat production by 1667.5kg/ha at an increase rate of 19.7%,compared to no application of BM straw decomposition inoculant based on 375kg/ha of DAP.
