Study Of Cultivation Of Two Wild Flowers

The research was done in nursery of Agriculture University of Hebei.The research mainly includes introduction,cultivition,and adaptability of 2 wildflowers: Echinops latifolius, Elshollzia stauntoni.The results were as follows:1 Echinops latifolius has high germination percentage and germination index on which different germination temperature and warter temerature had no influnce .Treating the seeds with water of 50℃-60℃before cultivite when outdoor temperature between 15℃and 20℃could lead to high gemination percentage. Germination temperature has no influnce on Elshollzia stauntoni seed germination.Different temperature water has certain influnce on seed germination of Elshollzia stauntoni, rearing the seeds with water of 50℃before cultivite when outdoor temperature between 15℃and 20℃could lead to high gemination percentage.2 After seeding during the last 10 days of Mar, Echinops latifolius sprouted during the middle 10 days of Apr.During the middle 10 days of Jun., Echinops latifolius formed whole plant. Echinops latifolius started to wilt during the middle 10 days of Oct. After seeding during the last 10 days of Mar, Elshollzia stauntoni sprouted during the last 10 days of Apr.During the middle 10 days of May Elshollzia stauntoni formed whole plant. Elshollzia stauntoni started to wilt during the middle 10 days of Otc.3 Echinops latifolius has a wild adaptability.It coμld adapt different irradiance and soil.It coμld be planted under different environment. Elshollzia stauntoni could adapt different irradiance and soil.It could be planted under different environment.Different irradiance has certain influnce on its height.4 Both of 2 wilde flowers could live in the soil which salt pencentage is 0.1% and 0.3%.They could not live in the soil which salt pencentage is bighter than 0.5%.5 Heat tolerance of Echinops latifolius, Elshollzia stauntoni was measured by clectrolyte leakage.Sigmoidal response curve existed between the relative injury value occurring in leaf tissue discs and treatment temperature,which accorded with Logostic equation.The LT₅₀ was Echinops latifolius62.41℃, Elshollzia stauntoni 60.98℃,respectively according to formula.
