【摘要】 以福建省桐口国有林场毛竹林为研究对象,通过研究铜元素对铝毒害之响应,以期了解铝毒害对毛竹笋品质的影响。采用回归旋转组合设计进行毛竹林铝毒害的田间试验。统计分析表明土壤酸性和A l离子浓度对毛竹笋铜元素含量有显著影响,且其影响在第1年呈负相关关系,随着时间的推移,到第2年呈正相关关系。A l离子处理对毛竹笋Cu元素含量前期呈抑制作用;随着时间的推移,土壤中的A l离子浓度持续下降,到第2年A l离子对Cu元素含量呈促进作用,Cu元素含量显著增加。更多还原

【Abstract】 Regarding the bamboo stand as the object of study on Tongkou forest farm in Minhou of Fujian Province,the response to copper element from aluminum poisons was studied,in order to understood the effect of aluminum poisons on bamboo shoots quality.In this experiment,the method of the field test and the experiment were selected to analyze unifies.The multi-dimensional statistical method were used to analyze the collected data.The results showed that soil sourness and the aluminum ion concentration had the remarkable influence on the copper element content in bamboo shoots.Also its influence in the first year was the inverse correlation relations,and in the second annual variation for positive correlation.Al treatment had the inhibitory action on Cu element content in the bamboo shoots.Along with the time lapse,Al ion concentration in the soil could drop continually,Al Ion content turned the promoter action to Cu at the 2nd year,the Cu ion content remarkable increase.更多还原
