摘要
[目的]研究铁皮石斛组培苗移栽基质的理化性质对栽培效果的影响。[方法]通过试验比较不同原料、不同配比的移栽基质的理化性质、营养成分对铁皮石斛移栽成活率、病害发病率、多糖含量的影响。[结果]以48%废弃食用菌糠、5%中草药废渣、11%桑秆+玉米芯、11%食物废弃壳、8.5%黏土+草皮土、6%木屑混和而成的栽培基质具有较适宜的理化性质和合理的营养成分,能有效减少铁皮石斛病害的发生,对植株的成活率、植株生长、多糖含量及产量均有明显影响。[结论]移栽基质的理化性质是影响铁皮石斛组培苗移栽时生根成活的关键因素。
Abstract
Objective] The aim was to study effects of physicochemical properties of Dendrobium officinale tissue culture plantlets transplan-ting medium on cultivation.[ Method] Effects of physicochemical properties and nutrient composition of medium with different raw material and ratios on transplanting survival rate, morbidity, content of polysaccharides of D.officinale were compared through experiment.[ Result] The results showed that the culture medium of 48% abandon fungus chaff, 5% waste residue of Chinese herbs, 11% mulberry+corncob, 11%wasted food shell, 8.5% clay+soddy soil and 6% sawdust had optimum physicochemical properties and appropriate nutrients to effec-tively reduce the diseases,also had significant effect on survival rate of plant, plant growth, content of polysaccharides and yield.[ Conclu-sion] The physicochemical properties of medium is the key factor to influence the survival rate of D.officinale tissue culture plantlets in trans-planting.
