几种无土栽培代用基质对花卉种子萌发的影响

The Effect of Several Substitute Media of Soilless Culture on the Germination of Flower Seeds

通过种子发芽试验探讨发酵后的木屑、花生壳、酒糟、大豆秆、玉米芯、椰糠等作为无土栽培基质的可行性。统计分析了基质以及其浸提液对种子发芽以及胚根伸长的影响,并引用发芽指数进行了比较。结果表明:椰糠、花生壳粉、木屑条件下的某些生长指标接近甚至超过两种传统的泥炭基质,其中花生壳粉作为花卉育苗基质具有较强的广普性。测定了不同基质中总酚酸的含量,初步分析了造成发芽过程中生长抑制的原因。

Discussed the posibility of sawdust, powder of peanut hull, powder of maize core etc. as soilless culture media. The effect of the different materials and extract on the germination and the growth of the radicle root of flower seeds were measured. The germination index （GI） were introduced into the experiment as the most important guide line. The results showed that under the cocoa nut coir, powder of peanut hull and sawdust conditions, most of the growing index of the flower seeds were close to or even better than the traditional peat moss cultural medias. The powder of peanut hull is a kind of widely applicable seeding substrates. The total phenolic acids contents of different materials were also tested in the experiment, the reason of holding hack the germination was also analyzed primarily in the paper.
