| 摘 要： | 桉树(Eucalyptus)已经成为我国南方发展速生丰产林的战略性树种(谢耀坚,2003).据不完全统计我国现有桉树人工林总面积已经达到190万hm2,每年新造林面积达几十万公顷,需要培育大量的优质苗木以满足桉树生产的需要(谢耀坚,2006).目前桉树造林70%以上采用扦插苗,少量用组培苗,极少用种子苗.传统的大田采穗圃是将优良无性系组培苗(生产上叫母苗)种植在大田上土壤中,不断地修剪和采穗,以繁殖扦插苗. |

| Abstract: | 10 solutions of different concentration of N, P, K, Ca, Mg, S were used to culture the hedges in the experiment while the traditional hedges growing on soil is used as control. 8 indexes including cutting length, number of cutting burl, diameter of cutting, fresh mass of cutting, dry mass of cutting, index of fresh hydrophytic root, lignification degree of cutting, survival rate of cuttings have been measured and analyzed. The difference between solution hedges and soil hedges is signifcant. The content of nutrition irons effects cuttings quality and rooting percentages directly. The lignification degree is negatively correlated with diameter of cutting, cutting length, number of cutting burl, fresh mass and dry mass, while the survival rate of cuttings is positively correlated to lignification degree and index of fresh hydropuytic root. Among all solutions No.5, No.6, No. 8 have good affection for hedges culture, their cuttings are usually have suitable diameter and length, and high rooting percentages. No. 6 is the best solution. |
