| 摘 要： | 目的]探索小麦秸秆资源化利用效果。方法]将腐熟的小麦秸秆、珍珠岩和蛭石按不同比例混配成小麦秸秆育苗基质,研究其在辣椒穴盘育苗上的效果。结果]将60%~90%的小麦秸秆和珍珠岩、蛭石进行复配,基质的容重、总孔隙度、持水孔隙度、电导率及pH均满足基质行业要求。70%小麦秸秆+15%蛭石+15%珍珠岩处理容重为0.227 g/cm~3,总孔隙度为93.7%,显著优于其他处理,壮苗指数为0.132,根冠比为0.493,叶绿素含量为2.85 mg/g,效果显著优于商业基质,根系活力分别较纯秸秆和对照高28.87%和4.16%。结论]70%小麦秸秆复合育苗基质更适合于辣椒幼苗生长发育,育苗可以达到壮苗标准,其可作为辣椒育苗基质使用。

| Abstract: | Objective]To explore the effect of resourceful utilization of wheat straw.Method]To study the effects of the wheat straw matrix which was composed by different proportions of decayed wheat straw,perlite and vermiculite on pepper plug seedling.Result] With the complex of 60％ ～90％ wheat straw,perlite and vermiculite,the matrix density,total porosity,water-holding porosity,conductivity and pH satisfied the requirements of the matrix industry.Bulk density and total porosity of 70％ wheat straw + 15％ vermiculite + 15％ perlite were 0.227 g/cm3 and 93.7％,the treatment was significantly better than other treatments.Under the treatment,the strong seedling index was 0.132,the root-canopy ratio was 0.493,the chlorophyll content was 2.85 mg/g,which were sigrnificantly bigher than the commercial substrate.The root vigor was 28.87％ and 4.16％ higher than pure straw and control,respectively.Conclusion] 70％ wheat straw seedling substrate is more suitable for the growth and development of pepper seedlings,nursery seedlings can meet the standard,which can be used as pepper seedling substrate. |
