摘 要:扦插种植巴戟时,间种木茨等遮荫作物.荫蔽度约65%左右,能有效地降低气温,地温,提高空气相对湿度,创造一个插植苗度夏的良好小环境,提高插条成活率20%以上,并能促进一年生苗的生长,使之在根、茎、叶等的生物量分配比例更为合理和生长茁壮,整丛生物生产比纯种地的高34%。When plant Morinda officinalis by means ofstem cutting, intertill in advance the shading crops as Manihot esculenta which create shady condition.The intertilled crops were able effectively to reduce the light intensity,lower air and soil temperature, and raise air relative moisture.An advantageous condition protected stem cutting from strogh sun and Iower moisture in the summer is created under intertilled crops.As compared with single-planting,a survival rate of stem cutting is higher 20%, leaf area,vines Iongth,biomass of adventitious roots and totalling biomass of whole thicket in the inter-planting region were more. Strong light intensity is unfavourable for annual seedling of M. officinalis developing from stem cutting and they need proper shady condition.
