铁皮石斛栽培废料和菇渣配制基质对草莓生长、产量及品质的影响

以铁皮石斛栽培废料和菇渣为主要原料,与土壤按不同体积比配制成栽培基质,并以纯菇渣和纯铁皮石斛栽培废料为对照,进行草莓盆栽试验。结果表明,配制的栽培基质营养元素均衡丰富,容重、电导率、孔隙度、pH值等理化性质均适合草莓生长,不同配方的基质对草莓植株营养生长无显著影响,但配方H1(80%菇渣+20%土)和H5(80%铁皮石斛栽培废料+20%土)的草莓产量显著(P<0.05)高于其他配方,草莓可溶性固形物、维生素C、可溶性糖含量,以及固酸比均以配方H5最高。配方H5的综合栽培效果优于其他配方,适用作草莓栽培基质。

Effects of substrates prepared from Dendrobium officinale cultivation waste and mushroom residue on growth,yield and quality of strawberry

Strawberry pot experiments were performed on compound substrates, which contained different ratios of Dendrobium officinale cultivation waste (DOCW) or mushroom residue (MR), and the single component substrates, which contained either DOCW or MR, were designed as controls. It was shown that the compound substrates contained more abundant and balanced nutrient elements, and their physical and chemical properties, such as bulk density, electrical conductivity, porosity and pH value were more suitable for strawberry growth. There were no significant differences in nutritional growth of strawberry among different treatments. However, significant differences in reproductive growth such as fruit quality and strawberry yield were found among treatments. The yield of strawberry in treatment H5 (80% MR+20% soil) and H1 (80% DOCW+20% soil) were significantly (P<0.05) higher than the other treatments, and the contents of total soluble solid, vitamin C, soluble sugar, and the ratio of total soluble solid to titratable acidity in H5 were the highest among all the treatments. Therefore, the comprehensive cultivation effects of treatment H5 on strawberry were obviously superior, and it deserved promotion as compound substrate for strawberry cultivation.
