据国内有关单位和我所近四年(1978到1981年)的试验证明:种植无毒薯增产效果显著。但马铃薯的殖繁系数较低(一般十倍左右),因此无毒薯的增产作用在生产上不能迅速发挥。为了解决这个问题,我所用腋芽扦插法高速繁殖无毒种薯的技术在1979—1980年试验,示范成功。但问题是建塑料薄膜大棚(育苗棚、假植棚)投资较大, According to the relevant domestic units and my nearly four years (1978 to 1981) test proved that: planting non-toxic potato yield a significant effect. However, the potato reproductive coefficient is low (usually about ten times), so the production of non-toxic potato production can not be quickly developed. In order to solve this problem, the axillary bud cutting method used in the rapid propagation of non-toxic seed potatoes in 1979-1980 test, demonstration success. But the problem is to build a plastic film greenhouse (nursery shed, fake shed) greater investment,
