嫁接砧木对拱棚连作辣椒生长发育、产量及品质的影响

Effects of Grafting Stock on Growth,Yield and Quality of Continuous Cropping Pepper

以引选的6份辣椒砧木("神根二号""青园砧木""新峰四号""砧强""神根F1""天骄F1")为研究对象,采用随机区组排列,对拱棚连作辣椒生长指标、产量及品质进行了研究。结果表明:拱棚连作辣椒株高、茎粗、开展度、单株结果数、净光合速率方面,"神根二号"辣椒砧木材料均高于其它砧木及"亨椒1号"(CK),"神根二号"的小区总产量、折合667m2产量和产值均最高,分别为171.5kg、4 888.5kg、6 746.1元,分别比"青园砧木""新峰四号""砧强""神根F1""天骄F1""亨椒1号"(CK)667 m2产量增加了17.9%、2.7%、1.8%、2.2%、9.7%、3.4%,"神根二号""神根F1"维生素C含量最高,分别为96.2、95.4mg·g^(-1),其它4份辣椒砧木维生素C含量差异不显著,"亨椒1号"维生素C含量最低,为38.2mg·g^(-1)。综合分析"神根二号"辣椒砧木材料是适合彭阳地区辣椒嫁接的优良砧木。

Six selected pepper rootstocks（‘Shengen No.2＇‘Qing Yuan rootstock＇‘Xinfeng No.4＇‘Zhenqiang＇‘Shengen F1＇and‘Tianjiao F1＇）were selected as research objects.Using random group arrange,growth index,yield and quality of pepper continuous cropping were studied.The results showed that fruit height,stem diameter,development degree,fruit number per plant and net photosynthetic rate,the rootstocks of ‘Shengen No.2＇were all higher than other rootstocks and‘Hengjiao No.1＇（CK）,the total output of‘Shengen No.2＇,the yield equivalent to 667 m2,and the value of 667 m2 were the highest,171.5 kg,4 888.5 kg,6 746.1 RMB,respectively.Compared with‘Qing Yuan rootstock＇‘Xinfeng No.4＇‘Zhenqiang＇ ‘Shengen F1＇ ‘Tianjiao F1＇（CK）,yield increased 17.9%,2.7%,1.8%,2.2%,9.7%,3.4%,respectively,the highest content of vitamin C in‘Shengen F1＇and ‘Shengen No.2＇,96.2,95.4 mg·g^-1,respectively,there was no significant difference in vitamin C content among the other 4 pepper rootstocks.The content of vitamin C of‘Hengjiao No.1＇was the lowest,38.2 mg·g^-1,comprehensive analysis,‘Shengen No.2＇rootstock was a good rootstock suitable for grafting pepper in Pengyang area.
