Abstract:: Taking ‘Longyao 1’ as material，four cultivation management modes including open field(CK)，plastic film，small arch shed and double film were conducted to study ground temperature of 0～25 cm，the germinating time，agronomic traits，yield and net income and other indexes，in order to propose a better cultivation pattern of ‘Longyao 1’ in northwest dry zone.The results showed that small arch shed，covered with plastic film and double film treat could improve soil temperature of every layer in 0～25 cm，daily average and each period，therefore，yam could be sowed advanced 10 d than CK，meanwhile the growth period could be prolong 20～30 d with these treatments；all these treatment was advantaged to the individual growth of yam.The yield of small shed treatment was 1 098.96 kg/667m²，it could be improved 5.01% than the double membrane cultivation，32.68% and 30.62% than plastic film mulching and CK respectively.The net income of small shed was 12698.28 yuan/667m²，it could be improved 10.24% than the double membrane cultivation，49.80% and 40.68% than plastic film mulching and CK respectively.
