摘要
为了筛选出适合育苗的轻基质,研究不同轻基质处理对1年生火力楠(Michelia macclurei)容器苗地径、苗高、植株鲜重和干重、叶面积、叶片厚度、叶片SPAD及叶片相对氮含量的影响,并利用隶属函数值对不同处理进行综合评价。结果表明,不同轻基质处理对1年生火力楠容器苗生长的影响为T4>T2>T1>T5>T3>T6>T7,最佳的轻基质处理为椰糠∶松树皮∶泥炭土∶黄心土=3∶2∶1∶1。
In order to select suitable light substrates for growing seedlings,effects of different light substrates on ground diameter,seedling height,plant fresh weight and dry weight,leaf area,leaf thickness,leaf SPAD,and leaf relative N content of 1-year-old Michelia macclurei container seedlings were studied,and different substrates were evaluated by subordinate function values.Results showed that different light substrates were sorted by T4>T2>T1>T5>T3>T6>T7.The best treatment was coconut bran∶pine bark∶peat soil∶yellow soil=3∶2∶1∶1.
