摘要
[目的]探讨不同环束高度对龙榛育苗的影响,为培育优质壮苗提供技术支撑.[方法]以龙榛5个品种为试验材料,开展不同环束高度对根蘖育苗影响的研究.[结果]不同环束高度对龙榛育苗的生根率、合格苗率及苗木生长有着明显影响,以环束高度为地面以上2 cm处理时根系和苗木生长指标最优;不同龙榛品种对环束高度处理也表现出差异,以龙榛4号表现最优.[结论]不同龙榛品种育苗适宜的环束高度为地面以上2 cm处.
Abstract
[Objective] To discuss the effects of ring beam height on seedling growth of Corylus heterophylla × C.avellana,and to provide technical support for the cultivation of high-quality seedlings.[Method] With five varieties of Corylus heterophylla × C.avellana as the test materials,seedling technique of ring beam height was researched.[Result] Ring beam height had significant impacts on the rooting rate,qualified seedling rate and seedling growth.The growth indexes of seedling and root system were the optimal when ring beam height was 2 cm above the ground.Different varieties showed differences on ring beam height treatment;and variety No.4 showed the optimal performance.[Conclusion] The optimal ring beam height of different varieties of Corylus heterophylla × C.avellana is 2 cm above ground.
