| 摘 要： | 种基盘造林法是一种局部改善植物生长环境的播种技术,为了使其更好的应用于华北土石山区播种造林,本研究在种基盘基质配方中添加了复合海藻肥(SCF)和土壤防蚀剂(SED),并对不同用量组合下的15种配方进行了吸水试验和蒸发试验。结果表明,这2种添加物能有效改善基盘的保水性能,其中SCF对基质饱和含水量、吸水速率和蒸发失水比的影响均显著,并且用量为0.75 g.m-2时,吸水速率和饱和含水量最大、蒸发失水比最小,保水性能较好;SED对基质饱和含水量和吸水速率的影响不显著,对蒸发失水比的影响显著,并且用量为4 g时蒸发失水比最小,抑制蒸发的效果最好。

| Abstract: | Afforestation with seed-base is a method to partly improve the growth environment of plants.In older to bring the technique applied to North mountainous areas in China,it was modified by adding seaweed fertilizer(SCF) and soil corrosion inhibitor(SED).Fifteen formulae with different combinations of SCF and SED the were examined from the performances of water absorption and evaporation.The results showed that these two additives could effectively improve the water absorbency of seed-base.SCF had obviously ef... |
