摘要
蛹虫草是一种珍贵的药、食同源大型真菌，其市场需求量日益增加。为了实现蛹虫草的工厂化生产，采用正交多项式回归分析法构建数学模型，揭示了温度对蛹虫草菌丝生长速率、菌丝长势、菌丝转色、子座分化、子座生长及产量的影响规律。结果表明，蛹虫草菌丝生长速率最大时的环境温度为22．7℃，转色的最佳温度为20．2℃，子座分化的最佳温度为18．1℃；在人工栽培时，适宜的发菌温度为15～18℃，子座生长的适宜温度为14～17℃。该研究结果为蛹虫草规模化生产的环境控制提供了依据。
The market requirement of Cordyceps rnilitaris, a valuable edible and medicinal fungus, is increasingly growing. A mathematic model is established by adopting orthogonal polynomial regression method to study the effects of temperature on hypha growth rate,development,and stroma differentiation, growth,and yield of Cordyceps militaris . The results show that the optimal temperature for the hypha growth,hypa color turned,and stroma differentiation is 22.7 ℃ ,20.2 ℃ and 18.1 ℃ ,respectively,and the appropriate temperature for the hypha and stroma growth under artificial culture is 15-18 ℃ and 14-17 ℃ ,respectively. The research provides scientific basis for the production of cordyceps militars on a large scale.
