摘要
该实验采用循环潮水式灌施营养液法对适合白桦容器育苗栽培用的营养液浓度进行了比较试验 .对不同营养液处理的试材白桦生长状况 (包括植株生长量、叶绿素合量、光合能力及叶片营养元素含量等 )进行分析比较 ,结果表明 :不同浓度处理的欧洲盆花标准营养液Sonneveld液中 ,以 1S浓度处理的白桦小苗生长表现最佳 .用山崎肯哉公式计算得出 ,适合白桦容器育苗栽培的最佳营养液配方为大量元素 (mmol·L- 1 ) :N 9 16 ,P 3 48,K 3 78,Ca3 2 5 ,Mg 0 79.
This study compared and screened 3 different strengths of Sonneveld nutrient solution (NS) for container growing of \%Betula platyphylla\% with automatically recirculating ebb & flow subirrigation systems.By analyzing and measuring plant growth,leaf chlorophyll contents,net photosynthesis and nutrient element concentration of \%B.platyphylla\% treated in different strength of Sonneveld solution,the results indicated that the growth and development were optimum in 1S strength of NS treament.Calculated by Yamazaki's formula the authors made up an optimum NS composotion for container culture of \%B.platyphylla,\%the macronutrients as follows:N 9 16,P 3 48,K 3 78,Ca 3 25,Mg 0 79.
