| 摘 要： | 本研究旨在探讨不同培育基质对华北落叶松容器苗苗木质量的影响。培育基质设置了6种配方,分别是:森林土(10);草炭土∶猪羊厩肥∶黄土(6∶3∶1);草炭土∶鹿粪∶黄土(7∶2∶1);阔叶腐殖土∶酵母菌生态有机肥(8∶2);草炭土(10);阔叶腐殖质土∶厩肥∶锯末∶黄土(5∶3∶1∶1)。对6种配方中的华北落叶松容器苗的苗高、地径、侧根数、主根长及高径比等生长指标进行了调查。结果表明:华北落叶松容器苗第6种基质配方的苗木质量最佳。基质配方2、4、6培育的华北落叶松苗木,在苗高、地径、侧根数上,与其他3种基质相比,均具有显著差异,而基质为纯草炭土在各项指标上表现效果不是最优。

| Abstract: | This research is for the purpose of discussing the effects of the different cultivated aggregate on the container-grown seedling quality of Lairx principis-rupprechtii. Cultivated aggregate was set by six formulae of mere forest soil （10） ; peat moss soil, pig and sheep sta- ble manure： loess （6：3：1）; peat moss soil ： deer dung loess （7 ： 2 ： 1）; broad-leaved humus soil yeast ecological organic fertilizer （8 ： 2） ; mere peat moss soil （10） ; and broad- leaved humus soil fellow fat ： sawdust the loess （5 ： 3 ： 1：1）, respectively. The con- tainer-grown seedling growth indicators in six kinds of cultivated aggregate such as seedling height ,stem base, lateral root number, root length and height-to-diameter ratio were sur- veyed. The results showed that the container-grown seedlings of Lairx principis-ruppre- chtii growed the best in Formula 6. Besides, the Larix principis-rupprechtii seedlings cultivated by substrate formulae 2, 4 and 6 have significances in terms of height, ground diameter and lateral root number com- pared with other three substrate formulae. However, the performances of each indicator for substrate formula with pure turfy soil are not the best. The comprehensive analysis showed that. the container seedlings of Larix principis-rupprechtii cultivated from the above men- tioned substrate formulae have the best quality. |
