摘要：To screen the best combination cultivation factors, the orthogonal test was conducted on the 6 factors of virus-free potato Favorite including sowing time, density, urea, calcium superphosphate, potassium sulfate and zinc, planted in paddy field of Xian-ning, Luo-tian and Guang-shui. The results showed that: a) experimental site had significant influence on growth period (F = 147.08>F_0.01), sowing date had great significant influence on growth period (F = 15.68>F_0.01), with the delay of sowing date, the growth period was short (R1 = 0.9851**). b) Density had great significant influence on yield (F = 4.0>F_0.01), the yield could be increased with the density increasing (R2 = 0.9782**), sowing date had significant influence on yield (F = 3.55>F_0.05). c) The maximum yield and economic return appeared at the treatment of seeding date December 10, seeding density 75000 plant/hm², N 75 kg/hm², phosphorus fertilizer 900 kg/hm², potassium sulfate 450 kg/hm² and zinc 22.5 kg/hm², with the yield 31185 kg/hm² and economic benefit 26833 Yuan/hm².
