摘要： 为探讨提高土壤中秸秆发酵效率的新途径，本试验采用盆栽方法研究了秸秆配施外源蛋白酶对土壤速效养分、有机质、pH值以及后季作物生长的影响。结果表明，整个种植期内，秸秆施酶处理土壤速效氮、磷、钾及有机质含量都高于不施酶处理，小麦收获时，施酶处理速效氮、磷、钾及有机质含量分别高出不施酶处理0.74~1.74mg/kg，0.53~1.33mg/kg，3.90~6.57mg/kg，0.07~0.13 g/kg；盆栽小麦叶绿素含量、根系活力、株高和干物质含量都比不施酶处理有所提高，子粒产量比对照提高19.84%~34.11%。可见，秸秆配施外源蛋白酶可以提高土壤肥力并且促进后季作物生长。

Abstract: In order to find the new way to promote the fermentation efficiency of crop straws,the influences of outer protease on soil fertility and the effects on growth of wheat were investigated by pot culture experiment.When the wheat were reaped,compared with the control,the contents of soil available N,available P,available K and contents of soil organic matter were increased 0.74-1.74mg/kg,0.53-1.33mg/kg,3.90-6.57mg/kg,0.07-0.13 g/kg.Compared with control,wheat height,dry weight,chlorophyll contents and root activity were all increased,grain yield were increased 19.84%~34.11%.Outer protease could improve soil fertility and promote the growth of wheat.
