摘要为了降低岩棉投入成本、提高经济效益并了解国产棉在无土载培中的应用效果，进行了不同产地的岩棉培番茄对比试验。试验结果表明：使用大连国产岩棉能降低生产投入成本39.48%，增加收入8.68%；产量比对照降低5.19%，达5%显等水平；能增加有效花稳数、平均果实数量、果实串数、单果重，但采实品质有所降低；基质内电导率不稳定，变化较大；使用荷兰进口岩棉虽然植株生长发育状况好于大连国产岩棉、产量高，但固投入成本高，纯收入低于使用大连国产岩棉。

AbstractIn order to reduce the input cost of rock wool, improve economic performance and understand the use effect of domestic rock wool on soilless culture, a comparative experiment of tomato growth in rock wool culture with rock wool from different production places is carried out. Experimental results show that use of rock wool made in Dalian, China can reduce input cost by 39. 48% , and increase income by 8.68% yield is lower by 5.19% than output of contrast, reaching the 5% significant level; productive panicle number, average quantity of fruit, quantity of fruit cluster and single fruit weight are increased, but fruit quality is decreased; electric conductivity in matrix is not stable, and has a large variation; by using rock wool imported from Holland, the growth and development conditions of plant is better than that using rock wool produced in Dalian, China and the yield is higher, but net income is less than that using Dalian rock wool.

无土栽培就是不用天然土壤而利用含有植物生长发育所必需的营养液来提供营养，并可使植物能够正常地完成整个生长周期的种植技术，又称为营养液栽培、溶液栽培、水耕、水培等。根据植物根系生长环境是否有固体基质的存在，无土栽裁培可分为无固体基质裁培和有固体基质裁培。无固体基质裁培是指根系生长的环境中没
有使用固体基质来固定根系，根系生长在营养液或含有营养液的潮湿空气中，可分为水培和喷雾培两种类型。有固体基质裁培是指植物根系生长以各种天然的或人工合成的材料作为基质，利用这些基质来固定植株并保持和供应营养及空气，常用基质有沙、岩棉、石砾、泥炭、锯木屑、蛭石、珍珠岩、片岩、火山熔岩、膨胀陶粒、树皮、甘
