本试验采用裂区设计，以营养液配方为主处理，中微量元素浇施次数为副处理。结果表明：以脱毒的克新２号为试材，在无土栽培条件下，在剪头苗快速生长期间，用 Ａ_３Ｂ_３处理表现产量高、粒数多、商品率高，而且成本低，Ａ_３Ｂ_３可以用于无土栽培生产微型种薯。
In this experiment, split-zone design was adopted to treat the nutrient solution as the main treatment, and the number of microelements was applied as the secondary treatment. The results showed that under the condition of soilless culture, the treatment of A23B_3 with high yield, large number of grains, high commodity rate, low cost, A_3B_3 Can be used for soilless cultivation of micro-seed production.
