平菇菌渣制备番茄栽培基质配方优化

Optimization of Tomato Bioculture SubstrateFormula from Oyster Mushroom Residue

为促进番茄有机生态无土栽培,本研究将平菇菌渣、牛粪和稻壳进行配比试验,以草炭和蛭石(体积比3∶1)为对照,研究不同配方对番茄生长、产量和品质的影响。结果表明:全废弃物制备的生物基质可达到商品基质的栽培效果,处理P3和P4(菌渣∶牛粪∶稻壳的配比为4∶3∶3或3∶3∶4)可获得较好的效果,与对照相比,P4产量和维生素C含量分别提高2.0%和6.3%。生物基质中丰富的养分和微量元素有助于作物生长,但需关注其盐分含量。

In order to promote soilless culture,different proportions of oyster mushroom residue,cow dung and rice husk were carried out in this study,taking peat and vermiculite(volume ratio 3∶1)as the control to study the effects of different formulas on the growth,yield and quality of tomatoes.The results showed that the biostroma prepared from total waste could reach the cultivation effect of commercial stroma,and the treatment of P3 and P4(bacterial residue∶cow dung∶rice husk∶ratio was 4∶3∶3 or 3∶3∶4)could obtain a better effect,and the yield and vitamin C content of P4 increased by 2.0%and 6.3%,respectively,compared with the control group.Rich nutrients and trace elements in biological matrix contribute to crop growth,but attention should be paid to its salt content.
