摘要
以红壤土、泥炭、珍珠岩、椰糠为基质原料,红壤土为CK,设计4种不同基质配比,对不同基质配比培育的蒜头果容器苗进行生长性状、叶绿素含量及生物量测定,并结合相关性分析、主成分分析和隶属函数值对容器苗的品质进行综合评价。结果表明:不同基质配比下,蒜头果幼苗的株高、叶片数、叶面积、叶绿素含量、须根自吸器数量与生物量均存在显著差异。其中T_(1)~T_(3)的幼苗株高分别为33.27、34.43、33.89 cm,显著高于T_(4)和CK;T_(1)、T_(2)和T_(4)的幼苗叶面积分别为10.79、12.21、11.88 cm 2,显著大于CK;T_(2)和T_(3)的叶片数及须根吸器数量与CK差异显著;T_(2)的植株叶片叶绿素含量最高,为7.75×10^(−4)mg/g,与T_(3)及CK差异显著;同时4种处理的地上、地下、全株鲜质量、干质量及壮苗指数显著高于CK。株高、叶片数、叶面积与生物量指标之间呈极显著正相关,不同基质配比的综合评价值为T_(2)>T_(3)>T_(1)>T_(4)>CK,其中蒜头果幼苗在T_(2)的基质配比中表现出明显的生长优势,为蒜头果容器育苗的最佳基质配比。
Four mixed substrates were designed using red soil,peat,perlite and coconut bran as substrate materials and red soil as control.The growth traits,chlorophyll content and biomass of Malania oleifera seedlings in different mixed substrates were measured,and the quality of container seedlings was comprehensively evaluated by correlation analysis,principal component analysis and membership function value.The results were as follows:there were significant differences in plant height,number of leaves,leaf area,chlorophyll content,the number of self-haustorium and biomass of M.oleifera seedlings among different mixed substrates treatments.The seedling height of T_(1)–T_(3)treatment were 33.27,34.43 cm and 33.89 cm,respectively,which were significantly higher than that of T_(4)treatment and CK.The leaves area of seedlings in T_(1),T_(2)and T_(4)treatment were 10.79,12.21 cm 2 and 11.88 cm 2,which were significantly larger than that of CK;there were significant differences in the number of leaves and self-haustorium between T_(2),T_(3)treatment and CK.The chlorophyll content in T_(2)treatment was the highest,which was 7.75×10^(-4)mg/g,significantly different from T_(3)treatment and CK.Meanwhile,the aboveground,aboveground,whole plant fresh mass,dry mass and strong seedling index of four treatments were significantly higher than those of the control.There was very significant positive correlation among plant height,leaf number,leaf area and biomass indexes.The comprehensive evaluation value of different mixed substrates was T_(2)treatment>T_(3)treatment>T_(1)treatment>T_(4)treatment>CK treatment.M.oleifera seedlings show obvious growth advantages in T_(2)treatment,which was the best mixed substrate for container seedlings of M.oleifera.
