以中薯2号的脱毒试管苗为试材,研究不同扦插密度与施肥模式对成都地区马铃薯微型薯产量的影响.结果表明:扦插密度为78株/盘(624株/ m~2),其产量最高,平均每盘合格薯为77.2个,平均每盘薯重155.5g;在生根第1、2周喷施烟草复合肥70 g+尿素30 g+水15 kg,在第3、第4周喷施烟草复合肥100 g+水15 kg,在第5、6周喷施烟草复合肥60 g+磷酸二氢钾40 g+水15 kg,采用该施肥处理产量最高,其单薯重为1.93 g,每盘产薯重178.4 g.

Using potato virus-free seedling of 'Zhongshu No. 2' as the experimental material, the effect of different cutting density and fertilizing model on yield of the mini-Potato in Chengdu were studied. The results indicated that the best cutting density was 624 plants/m~2 and the best fertilizing model was as follows: spraying fertilizer in rootage duration with 'tobacco compound fertilizer 70 g+carbamide 30 g+water 15 kg' in the first week and the second week, 'tobacco compound fertilizer 100 g+water 15 kg' in the third week and the forth week, 'tobacco compound fertilizer 60 g+potassium dihydrogen phosphate 40 g+ water 15 kg' in the fifth week and the sixth week.
