- 摘要:
- 以香菇品种“驻香706”（ZX706）、“驻香1号”（1732）、‘L808’及野生香菇（LYS）为试材，设置25、28、30 ℃ 3个温度梯度，采用构建菌丝生长与鲜质量动态积累的Logistic模型方法，研究了温度对香菇菌丝长度与鲜质量动态积累的调控效应，以期为香菇营养生长阶段生长特性预判及栽培温度精准化管理提供参考依据。结果表明：不同温度下，香菇菌丝长度及鲜质量与生长日数呈极显著正相关，相关性系数均达到0.96以上，随生长日数呈典型“S”型单向递增动态变化趋势。以生长日数为自变量构建的香菇菌丝生长与鲜质量Logistic模型具有良好的生物学意义，菌丝生长方程的R2为0.961 0~0.999 3，鲜质量方程的R2为0.974 5~0.998 8；相关系数分别介于0.980 3~0.999 6和0.987 2~0.999 4；菌丝生长nRMSE在1.515 1%~7.489 2%，鲜质量nRMSE为1.481 5%~8.737 9%，均小于10%，模拟曲线与实测值拟合度极高，达到极好预测结果。随温度的升高，菌丝生长到达最大生长速率所需的生长日数呈上升趋势，鲜质量则呈下降趋势，快速增长期平均生长速率、最大生长速率及达到最大生长速率的生长量均呈下降趋势。综合表明，不同温度下香菇菌丝长度与鲜质量动态生长存在明显差异，研究构建的Logistic模型拟合效果极好，具有较强的利用价值。
- Abstract:
- Taking four Lentinula edodes strains ‘Zhuxiang 706’(ZX706),‘Zhuxiang 1’(1732),‘L808’ and wild Lentinula edodes (LYS) as experimental materials,three temperature gradients (25 ℃,28 ℃ and 30 ℃) were set in this study.The regulatory effect of temperature on the dynamic accumulation of mycelial length and fresh weight of Lentinula edodes was investigated by constructing Logistic models for the dynamic accumulation of mycelial growth and fresh weight,in order to provide references for growth characteristic prediction during the vegetative growth stage and precise temperature management in Lentinula edodes cultivation.The results showed that mycelial growth and fresh weight of Lentinula edodes had highly significant positive correlations with cultivation days at different temperatures,with correlation coefficients all above 0.96,and showed a typical unidirectional increasing ‘S’ dynamic trend with the increase of cultivation days.The Logistic models of mycelial growth and fresh weight constructed with cultivation days as the independent variable had sound biological significance.The coefficient of determination (R2) of the mycelial growth equations ranged from 0.961 0 to 0.999 3,and that of the fresh weight equations ranged from 0.974 5 to 0.998 8;the correlation coefficients were 0.980 3-0.999 6 and 0.987 2-0.999 4,respectively. The normalized root mean square error (nRMSE) was 1.515 1%-7.489 2% for mycelial growth and 1.481 5%-8.737 9% for fresh weight,all less than 10%,indicating an extremely high fitting degree between the simulated curves and the measured values and excellent prediction results.With the increase of temperature,the number of days required for mycelial growth to reach the maximum growth rate showed an upward trend,while that for fresh weight showed a downward trend.The average growth rate,maximum growth rate during the rapid growth phase,and the growth amount corresponding to the maximum growth rate all showed decreasing trends.In conclusion,there were significant differences in the mycelial growth rate and dynamic fresh weight ccumulation of Lentinula edodes under different temperatures.The Logistic model constructed in this study had an excellent fitting effect and strong application value.
