摘要: 为提高水培富贵蕨的成活率及生长速度,进行不同基质(生化棉和定植篮)和日本园试营养液不同浓度(标准营养液、1/2标准营养液、1/4标准营养液和静置2 d的自来水)对水培富贵蕨根长、新叶数及植株鲜重增加量的影响研究,结果表明:经50 d的水培实验,以生化棉栽植的富贵蕨(根长(11.58±1.38)cm,新叶数(11.00±0.82)片,鲜重(22.00±0.82)g)优于以定植篮栽植的 富贵蕨(根长(8.95±0.79)cm,新叶数(9.25±0.96)片,鲜重(18.50±1.29)g),说明生化棉有利于富贵蕨栽植。在园试营养液不同浓度的试验结果中,1/2园试标准营养液培养的植株在生化棉和定植篮的根长、新叶数和鲜重增加量分别为((10.77±0.85)cm、(12.67±2.08)片、(19.67±2.08)g)和((10.20±0.61)cm、(11.33±1.53)片、(17.67±0.58)g),优于其他浓度,说明1/2园试标准营养液比较有利于富贵蕨的水培栽植。

Abstract: In order to improve the survival rate and growth rate of hydroponic Blechnum orientale, this research studied the effects of different substrate(biochemical cotton and colonization baskets)and Japanese garden nutrient solutions with different degrees of concentrations(standard nutrient solution, 1/2 standard nutrient solution, 1/4 standard nutrient solution and city water after standing for 2 days)on root length, number of new leaves and plant fresh growth weight. The results showed that after 50 days of hydroponic experiment, Blechnum orientale planted with biochemical cotton had better root length(11.58 ± 1.38)cm, the number of new leaves (11.00 ± 0.82)and the fresh weight(22.00 ± 0.82)g than those planted in baskets with the root length(8.95 ± 0.79)cm and the number of new leaves(9.25 ± 0.96), fresh weight(18.50 ± 1.29)g, indicating that biochemical cotton is conducive to the cultivation of rich ferns. Among the test results with different concentrations of nutrient solution in the garden, the root length, new leaf number and resh weight increment of biochemical cotton and colonization baskets were(10.77 ± 0.85)cm ,(12.67 ± 2.08),(19.67 ± 2.08)g and (10.20 ± 0.61)cm,(11.33 ± 1.53)and(17.67 ± 0.58)g respectively in the 1/2 standard nutrient solution, which suggest 1/2 solution is more conducive for the cultivation of the plant.
