摘要
[目的]研究不同处理方式对软荚红豆种子萌发和幼苗生长的影响.[方法]以软荚红豆种子为研究对象,分析不同浸种方式、消毒方式、种子破皮后处理方式及育苗基质对软荚红豆种子萌发、幼苗生长、生物量积累的影响.[结果]75℃热水浸种及破种皮后砂藏处理能极显著提高种子发芽率,显著促进幼苗生长和生物量积累;高锰酸钾消毒及火烧土:黄心土=1:2的培养基质在一定程度上能提高种子发芽率,促进幼苗生长和生物量积累.[结论]该研究为软荚红豆种子播种繁殖提供了技术支撑.
Abstract
[Objective] To research the effects of different treatments on seed germination and seedling growth of Ormosia semicastrata.[Method] With O.semicastrata seeds as the research material,effects of soaking method,disinfection method,treatment method after seed scarification and seedling substrate on the seed germination,seedling growth and biomass accumulation of O.semicastrata seeds were researched.[Result] Soaking in 75 ℃ hot water and sand hidden treatment after seed coat breaking extremely enhanced the germination rate of seeds,significantly promoted the seedling growth and biomass accumulation.K2 MnO4 disinfection,substrate of fire clay and yellow soil mixture (1 ∶ 2) promoted seed germination rate,seedling growth and synthesis of biomass accumulation.[Conclusion] This research provides technical support for the seed sowing propagation of O.semicastrata.
