- 摘要:
- 为筛选出适于板蓝根育苗的最佳基质，以食用菌下脚料为试材，将食用菌下脚料配比成6种基质，采用田间随机区组排列方法，研究了6种基质对板蓝根幼苗生长与生理特性的影响。结果表明：以商品基质与食用菌下脚料等体积混合基质处理（A4）的板蓝根幼苗株高、叶片数、主根根长、地上鲜质量、冠根比等形态指标与CK相比，分别高出5.36 cm、3.66片、2.52 cm、5.00 g和4.04；幼苗的光合速率、蒸腾速率、气孔导度和胞间CO2浓度等生理指标最大，分别为13.25 CO2 μmol?m-2?s-1、6.44 mmol?m-2?s-1、432 H2O mmol?m-2?s-1和376 μmol?mol-1，幼苗叶片中叶绿素含量最高可达12.78 mg?dm-2；综合分析处理A4的基质配比有利于板蓝根幼苗的壮苗培育。
- Abstract:
- To select the best substrate for Radix isatidis seedling，taking mushroom residue as test material，matching the mushroom residue of 6 kinds of substrates,by field random arrangement，the effects of 6 substrates on the growth and physiological characteristics of Radix isatidis were studied.The results showed that the values of plant height，leaf number，root length，fresh weight on the ground and crown root ratio of commoditymatrix and edible scraps from the volume mixing matrix(A4) were significantly higher than CK 5.36 cm，3.66 tablets，2.52 cm，5.00 g and 4.04 respectively.The photosynthetic rate，transpiration rate，stomatal conductance and intercellular CO2 concentration of the seedlings were also the highest，which were 13.25 CO2 μmol?m-2?s-1,6.44 mmol?m-2?s-1,432 H2O mmol?m-2?s-1 and 376 μmol?mol-1 respectively.The chlorophyll content of seedlings leaf reached 12.78 mg?dm-2;the results indicated that the treatment A4 was beneficial to the seedling cultivation of Radix isatidis seedlings.
