摘要
该文以无患子种子为试验材料,设置6种育苗密度D_1(5cm×25cm)、D_2(20cm×20cm)、D_3(20cm×15cm)、D_4(20cm×10cm)、D_5(15cm×10cm)、D_6(10cm×10cm),研究不同育苗密度对无患子幼苗生长和生物量积累的影响。结果表明:幼苗苗高在生长前期随育苗密度变化不明显,生长中期随密度增加而减少,后期受密度影响不明显;幼苗地径、幼苗根系及茎生物量在生长中期随育苗密度增加而减少,生长后期密度对地径生长影响不大;育苗密度对幼苗叶生物量的影响在各个时期则表现各不相同。
This paper designed the following six experiments by taking seeds of Sapindus mukorossi as materialson.The six seeding density was respectively（25cm×25cm）,（20cm×20cm）,（20cm×15cm）,（20cm×10cm）,（15cm×10cm）,（10cm×10cm）. By the above six groups of experiment,influence of seedling density on seedling growth andbiomass accumulation were studied. The results showed that the variation of seedling height was not obvious withseeding density at the early growth stage,reducing with the increasing of seeding density at the middle growth stage.The height affected by density was also not obvious at late growth stage. The biomass of seedling ground diameter,roots and stem decreased with the increasing of seeding density in catagen. Seeding density had a little effects onground diameter growth at later growth stage. The biomass of seedling leaf showed different in various periods.
