摘要
为探讨提取自黑龙江褐煤和新疆风化煤的矿源黄腐酸钾对水培绿萝生根和发芽的影响,开展了试验研究。试验设黄腐酸钾质量浓度为20、40、60、80 mg/L等4个浓度水平,分别测定并计算每个处理中10株绿萝的平均生根及发芽数量、根及叶的长度、根及叶的质量。结果表明:质量浓度40 mg/L的矿源黄腐酸钾可以较好地促进水培绿萝根系和叶的生长,高质量浓度的矿源黄腐酸钾则会抑制绿萝生根发芽;在相同质量浓度下,从褐煤和风化煤中提取的矿源黄腐酸钾对水培绿萝的生根、发芽无显著性差异。
In order to explore the effect of mineral potassium fulvic acid extracted from Heilongjiang lignite and Xinjiang weathered coal on the rooting and sprouting of hydroponic epipremnum aureum, an experimental study is being carried out. In the experiment, the mass concentration of potassium fulvic acid is set to 4 concentration levels: 20, 40, 60, 80 mg/L. The average rooting, sprouting number, average root, leaf length, average root and leaf mass of 10 plants of epipremnum aureum in each treatment are measured and calculated respectively. The results show that the mineral potassium fulvic acid with a mass concentration of 40 mg/L can promote the growth of the roots and leaves of the hydroponic epipremnum aureum and the mineral potassium fulvic acid with a high mass concentration can inhibit the rooting and sprouting of epipremnum aureum. When the mass concentration is the same, the mineral potassium fulvic acid extracted from lignite and weathered coal has no significant difference on the rooting and sprouting of hydroponic epipremnum aureum.
