摘要: 以3个品系的杂交兰组培苗为试材,研究秀珍菇菌渣添加量(10%、30%、50%、80%、100%)对栽培基质理化性质和杂交兰生长的影响。结果表明:与常规使用的栽培基质相比,添加秀珍菇菌渣可降低栽培基质的容重、通气孔隙度和气水比,提高持水孔隙度、pH值和电导率。在基质中添加不同比例的菌渣对杂交兰组培苗生长状况的影响不同。在GZ1-11和GZ3-7品系上,当菌渣添加量不超过30%时,杂交兰的生长状况与对照(使用常规栽培培基)相近或更优;在GZ2-1品系上,当菌渣添加量不超过50%时,杂交兰的株高,鲜重,根数,根长,假鳞茎横径、纵径等指标显著(p<0.05)高于对照。综合考虑,秀珍菇菌渣可作为栽培基质用于杂交兰生产,添加量以不超过30%为宜。

Abstract:

By using three types of hybrid orchid tissue culture seedlings as test materials, the effects of addition amount (10%, 30%, 50%, 80%, 100%) of Pleurotus geesteranus residue on the physicochemical properties of the cultivation substrate and the growth of hybrid orchids were investigated. It was shown that adding P. geesteranus residue reduced the bulk density, aeration porosity and air-water ratio of the substrate, while increased the water holding porosity, pH value and electrical conductivity, as compared with the commonly used cultivation substrate. Different addition amounts of P. geesteranus residue to the substrate had varying effects on the growth status of tissue culture seedlings of hybrid orchid. For the hybrid orchids GZ1-11 and GZ3-7, when the addition amount of P. geesteranus residue was not higher than 30%, their growth status was similar to or better than the control group (CK), which used the common cultivation substrate. For the hybrid orchid GZ2-1, when the addition amount of P. geesteranus residue did not exceed 50%, the plant height, fresh weight, root number, root length, and vertical and transverse diameter of pseudobulb were significantly (p<0.05) superior than those of the CK. Overall, P. geesteranus residue could be used in cultivation substrate for hybrid orchid production, with an appropriate addition amount not exceeding 30%.
