为了给塞罕坝林区华北落叶松移植容器育苗提供适宜的基质配比方案,在塞罕坝机械林场第三乡林场苗圃内,以阔叶腐殖土、草炭土、牲畜粪肥、黄土等做基质原材料,对其7种配比的育苗结果进行了筛选。通过多重比较,研究不同配比基质对苗木生长的影响。结果表明:不同基质对华北落叶松移植容器苗的地径存在显著性差异,对苗高、茎根比、鲜重和干重之间的影响差异达极显著水平。在塞罕坝林区培育华北落叶松移植容器苗,基质配比以阔叶腐殖土60%、猪羊厮肥30%、过磷酸钙8%、硫酸亚铁2%为最佳。
In order to provide a suitable matrix proportioning plan for the seedlings of Larix principis-rupprechtii in the Saihanba Forest Region, in the third rural forestry nursery of Saihanba mechanical forest farm, with broadleaf humus soil, peat soil, livestock manure and loess The matrix material was screened for its seven kinds of breeding results. Through multiple comparisons, we studied the effects of different ratio matrices on seedling growth. The results showed that there was a significant difference in the diameter of container seedlings of Larix principis - rupprechtii with different substrates, and the difference of seedling height, shoot - root ratio, fresh weight and dry weight reached a significant level. In the Saihanba area, Larix principis-rupprechtii could be transplanted to seedlings of pots. The ratio of matrix to 60% of broad-leaved humus soil, 30% pigs fattening sheep fat, 8% superphosphate and 2% ferrous sulfate were the best.
