试验调查了营养液浓度 ( 0 5～ 2倍 )和施用频率 ( 6、12、18次 /ｄ)对稻壳基质栽培非洲菊的影响。处理浓度为1 5倍时 ,花柄长度和直径 ,切花宽、重和产量都高 ;而浓度为 0 5倍时 ,生长减缓。高浓度 ( 2倍 )处理时 ,花柄长度短。与 2倍浓度的处理相比 ,浓度为 0 5～ 1倍时 ,
The effects of nutrient solution concentration (0-5 ~ 2 times) and application frequency (6,12,18 times / d) on the germination of Gerbera jamesonii were investigated. When the treatment concentration was 15 times, the length and diameter of flower stalk, width of cut flower, weight and yield were all high; when the concentration was 0 5 times, the growth slowed down. The stalk length is short when treated at high concentration (2x). Compared with 2-fold concentration treatment, when the concentration is 0-5 times,
