摘要
通过对沙地樟子松种子园中的树木进行施肥管理试验,结果表明:不同的肥料对樟子松的树木生长和开花结实产生显著差异,树高以处理4(施草碳75 kg.株-1)效果最佳;胸径以处理2(施猪粪60 kg.株-1)、处理6(羊粪60 kg.株-1)、处理8(施颗粒状氯化钾1.5 kg.株-1)的生长效果极显著,分别为3.82、3.74、3.65 cm,对于坐果率,施用无机肥的单株要高于施有机肥的单株,但持续时间较短。
Fertilizing experiments on trees of Pinus sylvestris var. mongolica seed orchard on sand land were conducted. The results show that different fertilizer can produce significant differences on growth and fruiting of Pinus sylvestris var. mongolica. Tree height get the optimal effect by treatment 4 (applying grass carbon 75 kg per plant) ;DBH get the extreme effect by treatment 2 (applying pig manure 60 kg per plant), treatment 6 (applying sheep manure 60 kg per plant), trentment 8 ( applying particle potassium chloride 1.5 kg per plant), and is 3.82,3.74,3.65 cm respectively. Fruit setting rate applying fertilizer is higher than individual applying manure and lasts a short time.
