不同基质配比对盆栽香菜生长及品质的影响

以“大叶香菜”为试验材料，设置T1（草炭∶蛭石∶珍珠岩=3∶1∶1）、T2（草炭∶蛭石∶珍珠岩∶有机肥=6∶1∶1∶2）、T3（草炭∶蛭石∶有机肥=3∶1∶1）、T4（草炭∶蛭石∶珍珠岩∶有机肥=2∶1∶1∶1）、T5（草炭∶蛭石∶珍珠岩∶有机肥=1∶1∶1∶1）和T6（草炭∶蛭石∶有机肥=2∶1∶1）共6种基质配比种植盆栽香菜，研究不同基质配比对盆栽香菜生长及品质的影响。结果表明，T4处理的盆栽香菜茎粗、根长和根体积等生长指标优于其他处理，全株鲜质量相对较大，为2.854 g，全株干质量具有最大值，为0.384 g。T4处理的品质指标可溶性蛋白含量、维生素C含量和叶绿素含量也相对较高，分别为37.78、0.20和2.02 mg/g。因此，建议使用草炭∶蛭石∶珍珠岩∶有机肥=2∶1∶1∶1的基质配比进行盆栽香菜的种植。 

Effects of Different Substrate Ratio on Growth and Quality of Potted Coriander

Effects of different substrate ratio on growth and quality of potted coriander were studied with six substrate ratios of T1(peat ∶ vermiculite ∶ perlite = 3 ∶ 1 ∶ 1), T2(peat ∶ vermiculite ∶ perlite ∶ organic fertilizer = 6 ∶ 1 ∶ 1 ∶ 2), T3(peat ∶vermiculite ∶ organic fertilizer = 3 ∶ 1 ∶ 1), T4(peat ∶ vermiculite ∶ perlite ∶ organic fertilizer = 2 ∶ 1 ∶ 1 ∶ 1), T5(peat ∶vermiculite ∶ perlite ∶ organic fertilizer = 1 ∶ 1 ∶ 1 ∶ 1) and T6(peat ∶ vermiculite ∶ organic fertilizer = 2 ∶ 1 ∶ 1) were set to plant potted coriander by taking "big leaf coriander" as experimental material. Results showed that, growth indexes such as stem diameter, root length and root volume of potted coriander treated with T4 were better than those of other treatments, and fresh weight of whole plant was relatively big, which was 2. 854 g. T4 had a maximum dry weight of whole plant was 0. 384 g.Quality indexes such as soluble protein content, vitamin C content and chlorophyll content of T4 were also relatively high, which were 37. 78, 0. 20 and 2. 02 mg∕g respectively. Therefore, substrate ratio of peat ∶ vermiculite ∶ perlite ∶ organic fertilizer =2 ∶ 1 ∶ 1 ∶ 1 was recommended for potted coriander.
