【摘要】 本研究在河北农业大学苗圃进行，主要对蓝刺头和木本香薷两种野生花卉的引种栽培和适应性进行了研究，结果表明：(1)蓝刺头种子发芽率、发芽势均较高，不同发芽温度和不同浸种温度对其影响均不大。户外温度在15℃到20℃时用50℃到60℃的水对其种子进行浸种处理，再进行播种育苗，可以较早的获得整齐一致的发芽率。发芽温度对木本香薷种子的发芽率有一定影响，不同温度水对木本香薷种子进行浸种处理对发芽率影响不大。户外温度在15℃到20℃时用50℃的水对木本香薷种子进行浸种处理播种育苗，再进行播种育苗，可以较早的获得整齐一致的发芽率。(2)蓝刺头3月下旬播种后，4月中旬开始萌发，5月上旬全部萌发并长出完整的真叶。6月中旬形成较为完全的植株。10月中下旬地上部分叶片开始枯黄。木本香薷3月下旬播种后，4月下旬开始萌发，5月中旬全部萌发并长出完整的真叶。6月中旬形成较为完全的植株。10中旬进入枯萎期。(3)蓝刺头能够适应不同的光照、土壤水平，适应性广泛，可以在不同的环境下栽培。木本香薷对不同的光照、土壤适应性较强，可以在不同的环境下栽培，但不同的光强会对木本香薷的株高有一定影响。(4)两种野生花卉在土壤盐分浓度为0.1％，0.3％的条件下均能正长生长，当土壤盐分含量＞0.5％时，两种野生花卉均不能成活。(5)测定梯度高温下膜透性的变化情况，计算出蓝刺头的半致死温度为62.41℃，木本香薷的半致死温度为60.98℃。更多还原

【Abstract】 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.更多还原
