以秸秆灰、草炭为试材,以番茄品种‘粉冠888’为研究对象,将未经科学处理的秸秆灰和草炭按不同配比混配成混合育苗基质,研究其理化性质及其在番茄穴盘育苗中的应用效果。结果表明:秸秆灰草炭混配基质的理化性质符合穴盘育苗效果要求,处理中混配基质A3(秸秆灰∶草炭(V∶V)=1∶1)育苗效果明显高于对照(草炭∶蛭石(V∶V)=2∶1),A3处理幼苗的壮苗指数和根冠比分别为0.163、0.124,比对照依次高出32.52%、13.76%;综合幼苗生长状况和生理代谢等指标可以确定,秸秆灰混配基质以秸秆灰和草炭等体积混合可以作为番茄穴盘育苗的基质。
Using straw ash and peat as test materials, the tomato cultivar ’Fengyuan 888’ was taken as the research object. The straw and peat not treated in different proportions were mixed into a mixed seedling matrix with different proportions to study its physicochemical properties and its effects on tomato Application Effect of Plug Seedling. The results showed that the physical and chemical properties of straw-ash-peat mixed substrate accorded with the requirement of plug-seedling. The effect of seedling mixed with substrate A3 (straw ash: peat (V:V) = 1: 1) (V:V) = 2:1). The seedling index and root / shoot ratio of seedlings treated with A3 were 0.163 and 0.124, respectively, which were 32.52% and 13.76% higher than that of the control respectively. The indexes of comprehensive seedling growth and physiological metabolism could be It was confirmed that the mixture of straw ash and matrix could be used as the matrix of tomato plug seedling by mixing the volume of straw ash and peat.
