Abstract: The author indentified thermal resources in Shenyang during peanut growing period from 1971 to 2010, basing on phenological observation data during peanut cultivation phase, by climate statistics and diagnostic methods, in order to take full advantage of thermal resources to avoid low-temperature hazards and adjust the agricultural and species distribution. The results showed that: the suitable peanut sowing period was postponed by 7.6 days in Shenyang, as for peanut species requiring 150 days or longer of maturation stage, their sowing, maturity and growth periods were lack of thermal resources to different degrees. During seedling and growth period, they were lack of thermal resources in 20% of years; during maturity period, they were lack of thermal resources in 10% of years. Therefore, local farmers shall select late-maturing peanut varieties requiring 140-150 days of maturation stage, which can take full advantage of thermal resources to avoid low-temperature hazards, and ensure stable income.
