不同载体及菌肥浸提液对苏丹草种子萌发的影响

Effects of bio-fertilizer extract with different carrierson seed germination of Sorghum sudanense

摘要:

为探究不同载体及菌肥浸提液对种子萌发的影响,采用有机堆肥、木炭、花土、菌糠、马铃薯渣和泥炭为供试材料,研究不同载体菌肥浸提液对苏丹草种子萌发的影响。结果表明:体积分数为25%和50%的不同载体及菌肥浸提液浸种均能显著促进苏丹草种子萌发,且25%复合载体菌肥浸提液显著优于25%单一载体菌肥浸提液;与CK相比,载体F4(泥炭∶菌糠∶花土)处理下的芽长、苗重、根长、根表面积分别提高24.4%,28.9%,69.6%,73.6%。主成分分析表明,50%处理组中,复合载体菌肥(F6除外)均优于单一载体菌肥;25%处理组中复合载体菌肥以F4最佳,F1和F3次之,单一载体菌肥中有机堆肥最佳,木炭次之。

Abstract:

The bio-fertilizer extract with different carriers (organic compost,charcoal,flower cultivate soil,fungus chaff,potato pulp and peat,6 formula) on seed germination of Sorghum sudanense was studied.Both thevolume fraction of 25% and 50% for bio-fertilizer extract of different carriers significantly promoted the seedgermination and the volume fraction of 25% for bio-fertilizer extract of composite carrier was superior to thesimplex carrier.Compared with control group,the bud length,sprout weight,root length and root superficial areawere enhanced by 24.4%,28.9%,69.6% and 73.6% respectively under F4 treatment.The principal componentanalysis showed that the bio-fertilizer with composite as carrier were better than the bio-fertilizer of simplexcarrier of 50% volume fraction (expect F6 treatment).For 25% volume fraction,F4 was the best,and F1and F3 were better with composite as carrier,The organic compost was the best and followed by charcoal in allsimplex carriers.
