摘要
为了筛选适宜枳砧木繁育的基质,采用红壤土、椰糠、泥炭、有机肥以不同比例配比组成23种基质用于枳容器苗培养,比较了不同基质上植株的株高、茎粗、根总长、根表面积、根直径、根体积、根尖数、地上部分鲜质量、地下部分鲜质量、地上部分干质量、地下部分干质量差异.结果表明,S15(红壤土∶椰糠∶泥炭∶有机肥=7∶2∶0∶1,体积比,下同)基质能提高枳苗木的茎粗、株高和地下部分干质量,分别比CK(红壤土)高出67.40％、86.79％和82.05％;S7(椰糠∶有机肥=7∶3)基质提高了植株根总长,比CK高出51.30％;S11(椰糠∶泥炭=7∶3)基质提高了地下部分鲜质量和地上部分干质量,分别比CK高出105.48％和207.14％;S14(椰糠∶泥炭=5∶5)基质提高了枳苗木地下部分干质量,比CK高出了 74.35％.结合考虑成本,筛选S15(红壤土∶椰糠∶泥炭∶有机肥=7∶2∶0∶1)基质为枳容器苗繁育的最适基质.
Abstract
In order to screen the suitable substrate for the breeding of Poncirus trifoliata rootstock,23 combi-nations of red loam soil,coconut peat,peat and organic fertilizer were used as substrates to cultivate P.trifoli-ata container seedlings.The plant height,stem diameter,root length,root surface area,root diameter,root vol-ume,root tip number,fresh weight of aboveground part,fresh weight of underground part,dry weight of aboveground part and dry weight of underground part were compared.The results showed that the substrate S15(red loam soil∶coconut peat∶peat∶organic matter=7∶2∶0∶1,by volume,the same below)increased the stem diameter,plant height and dry weight of the underground part of P.trifoliata seedlings by 67.40％,86.79％and 82.05％compared to that of control(red loam soil),respectively.The substrate S7(coconut peat∶organic matter=7∶3)increased the total root length by 51.30％compared with control.Compared with control,the substrate S11(coconut peat∶peat=7∶3)increased the fresh weight of underground part and dry weight of aboveground part of seedlings by 105.48％and 207.14％,respectively.The substrate treatment S14(coconut peat∶peat=5∶5)increased the dry weight of underground part of the seedlings by 74.35％.Con-sidering the cost and benefit comprehensively,substrate S15(red loam soil∶coconut peat∶peat∶organic matter=7∶2∶0∶1)was selected as the most suitable substrate formula for the breeding of P.trifoliata seedlings.
