棕榈不同播种密度对苗木产量和质量的影响

Effects Test of Different Planting Densities on Yield and Quality of Trachycarpu fortunei

通过对棕榈播种密度为10 cm×10 cm、15 cm×15 cm、20 cm×20 cm、25 cm×25 cm、30 cm×30 cm、35 cm×35 cm几种类型进行育苗试验,得出密度类型20 cm×20 cm合格苗产量最大,达到10 005株/667m2;播种密度25 cm×25 cm时苗木合格率最高,当密度大于和小于25 cm×25 cm时,合格率均呈下降趋势,当密度逐步大于25 cm×25 cm时,死亡率呈逐步上升的趋势;用播种密度25 cm×25 cm合格苗木造林,幼林林相最为整齐。

This experiment is to grow Trachycarpu fortunei tree with different sowing density including 10 cm× 10 cm, 15 cm× 15 cm, 20 cm×20 cm, 25 cm× 25 cm, 30 cm×30 cm, 35 cm× 35 cm. The result showed that the density of type 20×20cm had the most qualified seedling yield reaching 10 005 trees per 667 square meters; meanwhile, sowing density of 25 cm ×25 cm has the most qualified rate of seedlings, when the density is less than 25 cm×25cm, the qualified rate decreased gradually, and when the density is greater than 25 cm×25 cm, the mortality showed a gradual upward trend; with sowing density of 25 cm× 25 cm qualified seedlings afforestation, the young stands were consistent in uniformity.
