以平均苗高7.4cm、平均地径1.82 cm、无病虫害的一年生葛萝槭扦插苗为试验材料,采用农林废弃物醋渣、松针、菇渣主要基础性基质,分别与粉煤灰、树皮粉、锯末、羊粪以不同的体积比混合而成,对不同育苗基质上生长的葛萝槭的苗高、地径、叶片数、冠幅、成活株数进行调查。结果表明:处理9的成活率最高达到了92.78%,表现最好。处理9、处理1、处理3、处理8、处理10可推广使用;不同基质对苗高、叶片数的相对生长量存在显著性差异(α=0.05),对地径、冠幅的相对生长量不存在显著性差异(α=0.05);不同基质处理的葛萝槭的年生长规律一致即3月下旬到4月上旬进入树液流动期,4月中旬到6月上旬为植株的生长初期,6月中旬到8月为速生期,9月进入苗木的硬化期,且在7月中旬出现了生长暂缓期现象。
With the average seedling height of 7.4cm and the average diameter of 1.82 cm, the cuttings of annual gerbera maple without plant diseases and insect pests were used as test materials. The main basic substrates of vinegar residue, pine needles and mushroom residue of agricultural and forestry wastes were respectively mixed with fly ash, bark Powder, sawdust and sheep manure were mixed in different volume ratios. The height, diameter, number of leaves, crown width and number of surviving plants of D. davidiana grown on different seedling growing matrices were investigated. The results showed that the highest survival rate of treatment 9 reached 92.78%, the best performance. Treatment 9, Treatment 1, Treatment 3, Treatment 8 and Treatment 10 can be used widely. The relative growth of seedling height and leaf number of different substrates was significantly different (α = 0.05). The relative growth of ground diameter and crown width There was no significant difference (α = 0.05). The growth of R. solani under different substrates was in accordance with the law of annual growth. The flowering time was from late March to early April, and the flowering period was from mid-April to early June. June mid-August to fast-growing period, in September into the hardening period of seedlings, and in mid-July there growth retardation phenomenon.
