摘　　要：为了降低种薯成本、解决水肥等资源过度消耗的问题,本试验分析比较了高架苗床无土繁育模式和地面隔层无土繁育模式的水肥投入和产出效益。结果表明:与地面隔层无土繁育模式相比,高架苗床无土繁育模式有利于结薯,结薯个数增加72个/m2,增幅为4.58%,且直径≤25 mm的原原种居多,占总结薯个数的59.49%;节水0.184 m3/m2,节省肥料0.08 kg/m2,成本降低0.7392元/m2。In order to reduce the cost of seed potatoes and solve the problem of excessive consumption of water and fertilizer resources,this experiment analyzed and compared the water and fertilizer input and output benefits of the elevated seedbed soilless breeding model and the ground-interval soilless breeding model.The results showed that compared with the ground-interval soilless breeding model,the elevated seedbed soilless breeding model was conducive to potato formation,the number of potatoes increased 72 per m2,increased by 4.58%.The breeder′s seed with diameter≤25 mm formed the majority,accounting for 59.49%of the total number of potatoes.Water saved 0.184 m3/m2,fertilizer saved 0.08 kg/m2,and cost reduced 0.7392 yuan/m2.
