不同基质配比对涮辣幼苗生长的影响

Effects of Different Substrate Composition on Capsicum frutescens L.var.shuanlaense Seedlings

[目的]研究不同基质配比对涮辣幼苗生长的影响。[方法]采用4因子3水平设计,以涮辣株高、茎粗、主根长、主根粗、第一片真叶长、第一片真叶宽、第二片真叶长、第二片真叶宽、地上部鲜重、地下部鲜重、地上部干重和地下部干重12个形态指标和根系活力、子叶POD和CAT酶活性3个生理指标为评价标准,分析不同处理对涮辣幼苗影响。[结果]3种处理效果均高于对照,其中10%菜园土+20%珍珠岩+20%蛭石+50%营养土处理效果最好。[结论]该研究为涮辣育苗提供了理论依据。

[Objective]To research the effects of different substrate composition on Capsicum frutescens L.var.shuanlaense seedlings.[Method]Four factors and three levels design was adopted.12 morphological indexes(plant height,stem diameter,main root length,main root width,the length of first euphylla,the width of first euphylla,the length of second euphylla,the width of second euphylla,fresh weight of aboveground part,fresh weight of underground part,dry weight of aboveground part,dry weight of underground part)and 3 physiological indexes(root activity,cotyledon POD and CAT activities)of C.frutescens were used to evaluate the effects of different treatments on seedlings.[Result]Effects of different treatments were all superior to that of the control.Among them,treatment of 10%vegetable garden soil+20%pearlstone+20%roseite+50%nutrition soil showed the best effects.[Conclusion]This research provided theoretical basis for the seedling breeding of C.frutescens.
