Effects of Different Canopy Densities and Fertilization Treatments on the Growth Characteristics of Erythropalum scandens
摘要
Abstract
To investigate the adaptability of two-year-old cuttings of Erythropalum scandens,a woody vegetable,to canopy density,fertilizer type,and their interactions,initial theoretical support for the cultivation environment and fertilizer applica-tion of E.scandens was provided.This experiment used the full light treatment without fertilizer as the control group.It set up three canopy density levels(full light,0.42-0.51,0.81-0.93)and five fertilizer types(no fertilizer,single application of inor-ganic fertilizer,compound fertilizer∶bio-organic fertilizer=4∶1,compound fertilizer∶bio-organic fertilizer=1∶1,single application of organic fertilizer)in a randomized block design with a double factorial experiment to investigate the growth characteristics,yield,and water content of E.scandens under different canopy densities and fertilizer treatment conditions.The results revealed extremely significant differences(p＜0.01)in all the indicators between the control and the various treat-ment conditions.The L1F2(moderate canopy density+compound fertilizer∶bio-organic fertilizer=4∶1)treatment condition resulted in the best growth conditions,yield,and water content of E.scandens.For each fertilizer type,except for the increase in tender shoot thickness and water content,all the growth indicators first increased but then decreased as the canopy density increased.For the same canopy density and fertilizer application rate,all the growth indicators first decreased but then in-creased as the organic fertilizer application increased.The membership function analysis revealed that the growth effect of E.scandens under the condition of moderate canopy density(0.42-0.51)+application of compound fertilizer∶bio-organic fer-tilizer=4∶1 was the best.The appropriate fertilization ratio was selected to provide a theoretical basis for the seedling culti-vation technology of interplanted woody vegetables in forests.关键词
