摘要
以铁尾矿渣和草炭作为栽培基质进行设施蔬菜(番茄和黄瓜)的无土栽培生产,通过设置不同的铁尾矿渣和草炭配比,研究不同栽培基质对蔬菜枯萎病发病率、产量和品质的影响,以筛选适合蔬菜生产的基质配方。结果表明:30%尾矿渣与70%草炭配制的基质理化性质最接近于理想基质标准,营养成分含量最高,在设施蔬菜生产中产量最高、枯萎病发生率最低,且有效改善了产品品质。该项目能够实现工农业固定废弃物的综合利用,且能够带动设施蔬菜产业健康发展,具有较大的推广应用前景。
Iron tail slag and peat as the cultivation matrix with organic fertilizer for the soilless cultivation of facilities vegetable production,by adjusting the ratio of iron tail slag and peat,select the optimal ma-trix formula suitable for vegetable growth. The results showed that the physical and chemical properties of the ratio of 30% tail slag＋70% peat substrate accorded with the requirement of ideal matrix,the nutrient content of which was the highest. In the treatment the yield was the highest, blight incidence was the lowest,then the quality was improved. By scrap iron tail slag was used as the cultivation matrix for veg-etable production,not only can effectively overcome the facility vegetable soil continuous cropping obstacle problems,but also realizes the recycling of waste,improve the ecological environment effectively.
