摘要: 为建立毛竹Phyllostachys pubescens实生苗适宜的水培体系,以毛竹实生苗为材料,通过比较不同处理下毛竹实生苗的叶面积、生物量和光谱反射特征,以筛选Yoshida培养液为基础的水培营养条件。结果表明:1/2 Yoshida叶面积、增加生物量和光谱反射特征都优于其他Yoshida比例处理,其中生物量增加达到对照的97.9%。氮、磷、钾单因素试验表明氮素浓度3.0 mmolL-1处理各指标优于1.0,2.0,4.0,5.0 mmolL-1处理;磷素浓度1.0 mmolL-1处理优于0.5,1.5,2.0 mmolL-1处理;钾素浓度1.5 mmolL-1处理优于0.5,1.0,2.0,2.5 mmolL-1处理。氮、磷、钾三因素三水平正交试验L9(33)表明,氮素4.0 mmolL-1,磷素0.5 mmolL-1和钾素1.0 mmolL-1为较适宜毛竹实生苗生长的浓度配比。图12表6参35Abstract: To establish a solution culture protocol for hydroponic culture experiments with Phyllostachys pubescens(moso bamboo) seedlings,comparisons of leaf-area,increased biomass,and reflectance spectral characteristics were made using Yoshida nutrient solution of 1/4,1/2,1,3/2 and soil culture as a control(ck). Also,experiments for N with 1.0,2.0,3.0,4.0,and 5.0 mmolL-1 treatments;for P with 0.5,1.0,1.5,and 2.0 mmolL-1 treatments;and for K with 0.5,1.0,1.5,2.0,and 2.5 mmolL-1 treatments using univariate and multivariate statistics as well as three level(N:2,3,4 mmolL-1;P:0.5,1.0,1.5 mmolL-1;K:0.5,1.0,1.5 mmolL-1) Orthogonal Tests [L9(33)] were conducted. Results showed that leaf-area,increased biomass,and reflectance spectral characteristics of with a 1/2 Yoshida nutrient solution was superior to other strengths with an increaseded biomass of 97.9% of compared to ck. For N the 3.0 mmolL-1 treatment was superior;For P 1.0 mmolL-1 were was superior;and for K 1.5 mmolL-1 was superior. When N,P,and K levels were tested together using orthogonal testing,optimum seedling growth was with 4.0 mmolL-1 N,0.5 mmolL-1 P,and 1.0 mmolL-1 K.[Ch,12 fig. 6 tab. 35 ref.]
