| 摘 要： | 为探求提高土壤中秸秆发酵效率的新途径,采用室内培养和盆栽土培方式研究了秸秆配施外源纤维素酶对秸秆分解速率及后季作物生长的影响。结果表明,小麦秸秆、玉米秸秆加酶处理与不加酶处理的降解率存在极显著差异(p<0.01),到培养结束时,小麦秸秆加酶处理降解率高出不加酶处理7.10~11.86个百分点,玉米秸秆处理高出8.01~14.04个百分点;秸秆配施纤维素酶还可以促进后季作物生长,盆栽小麦籽粒产量比对照提高17.52%~29.61%,叶绿素含量、根系活力、株高和干物质含量比对照也有所提高。

| Abstract: | In order to find the new way to promote the degradation rates of crop straws,the influences of exogenous cellulose on degradation rates of straws and the effects on growth and development and physiological function of wheat were investigated by incubation experiments and pot culture experiments.The results showed that in the incubation time,the wheat straw and corn straw that added cellulose all have the significant difference,compared with ck(p<0.01).When the incubation finished,the degradation rate of wheat straw added cellulose were increased by 7.10-11.86 percentages,and the rate of corn straw were increased by 8.01-14.04 percentages.Compared with ck,exogenous cellulose can promote the growth of wheat.Wheat height,dry weight,chlorophyll contents and root activity were all increased and grain yield were increased by 17.52%-29.61%. |
