摘要
以半年生桢楠(Phoebe zhennan)幼苗为试材,采用L16(54)正交试验设计,研究了不同基质配比对桢楠幼苗生长量、生物量及苗木质量的影响。结果表明,不同的基质配比对一、二年生桢楠幼苗的苗高、地径、叶干质量、枝干干质量、根干质量均有显著影响(P<0.05)。基质配比椰糠∶泥炭土∶油樟叶∶农林废弃物∶腐殖土=4∶6∶2∶1∶4,表现均衡,综合评定结果最好,第二年比第一年地径增加5.18 mm,苗高增加50.23 cm;其次是基质配比为椰糠∶泥炭土∶油樟叶∶农林废弃物∶腐殖土=6∶6∶1∶3∶2,第二年比第一年地径增加4.06 mm,苗高增加45.99 cm。不同基质成分中对桢楠幼苗生长的影响大小为泥炭土>农林废弃物>腐殖土>油樟叶>椰糠.
In order to study the effects of different substrates ratios on the growth,biomass and seedling quality of Phoebe zhennan seedlings,the half-year-old Phoebe zhennan seedlings were used as the test materials with the L16(54)orthogonal experiment.The results showed that different substrates ratios had significant effects on the seedling height,ground diameter,leaf dry weight,branch dry weight and root dry weight of 1-and 2-year-old Phoebe zhennan seedlings(P<0.05).The substrate ratio of coconut bran(4),peat soil(6),oil camphor leaf(2),agricultural and forestry waste(1),humus soil(4)was the best treatment with the best growth indexes and balanced performance.And the comprehensive evaluation results were the best,among wich the ground diameter and seedling height in the second year increased by 5.18 mm and 50.23 cm respectively compared with the first year.The second best substrate ratio was coconut bran(6),peat soil(6),oil camphor leaf(1),agricultural and forestry waste(3),humus soil(2),in which the ground diameter and seedling height in the second year increased by 4.06 mm and 45.99 cm respectively compared with the first year.Effect of different substrate components on the growth of Phoebe zhennan seedlings were as follows:peat soil>agricultural and forestry waste>humic soil>oil camphor leaf>coconut bran.
