农业有机废弃物组合基质对脱毒马铃薯原原种经济性状的影响

Effect of Agricultural Organic Waste Combination Matrix on Economy Traits of Transplanted in vitro Potato Plantlets for Pre-elite Seed Production

在日光温室内,采用基质栽培模式,研究了废弃物组合基质与脱毒马铃薯原原种经济性状间的关系。结果表明:影响脱毒马铃薯原原种单粒重因素是菇渣>糠醛渣>牛粪>蛭石>沙子;因素间沙子:牛粪:蛭石:糠醛渣:菇渣最佳容积比为0.40:0.30:0.09:0.10:0.10。脱毒马铃薯原原种存活率:蛭石(CK)>废弃物基质;而株高、茎粗、叶片数、根系长、单株粒重、单粒重、单株粒数、繁殖效率、经济效益变化顺序是:废弃物基质>蛭石。

Using the substrate culture model, the relationship between combination matrix and economic traits of the transplanted in vitro potato plantlets was studied in the greenhouse. For single minituber weight, the influence of the factors was mushroom waste 〉 furfural residue 〉 cow dung 〉 vermiculite〉 sand, and the best volumetric ratio of sand： cow dung： vermiculite： furfural residue： mushroom waste was 0.40： 0.30： 0.09： 0.10： 0.10. Except for survival percentage of transplanted in vitro potato plantlets, all other traits, including plant height, stem diameter, leaf number, root length, minituber yield per plant, single minituber weight, minituber number per plant, reproductive efficiency, and economic benefit, were better when in vitro plantlets were transplanted into waste matrix than vermiculite.
