| 摘 要： | 平菇生长发育期间所需水分大部分来自培养料,而培养料缺水,易导致平菇减产。为了解决这一问题,试验采用在培养料中添加不同比例(0.1%、0.2%、0.3%、0.5%)的保水剂,研究分析添加保水剂对平菇生长的影响。结果表明:保水剂的施入,促进了平菇采摘次数、总产量和水分利用效率的增加。与CK(不添加保水剂)相比,4种不同比例保水剂施用下平菇采摘次数分别提高10%、11.11%、14.44%、16.67%;总产量分别提高8.73%、17.68%、50.94%、45.32%;水分利用效率分别提高0.74%、1.70%、22.07%、4.27%。通过对总产量和水分利用效率综合分析,保水剂添加比例为0.3%时,总产量和水分利用效率提高效果较佳。而根据保水剂持水量与总产量相关性分析可知,保水剂添加比例为0.455%时,总产量达到最大。因此,建议在平菇生产中保水剂添加比例为0.3%~0.455%。

| Abstract: | Most of the water needed for the growth and development of Pleurotus ostreatus comes from the culture materials,and the lack of water in the culture materials can easily lead to the reduction of Pleurotus ostreatus.In this experiment,different proportions(0.1%,0.2%,0.3%,0.5%)of SAP are added to the culture materials to study and analyze the effect of adding SAP on the growth of Pleurotus ostreatus.The results show that the application of SAP promotes the increase in the number of picking times,total yield and water use efficiency of Pleurotus ostreatus.The total yield increases by 8.73%,17.68%,50.94%and 45.32%,respectively.The water use efficiency increases by 0.74%,1.70%,22.07%,and 4.27%,respectively.Through comprehensive analysis of total yield and water use efficiency,when the proportion of SAP is 0.3%,the total yield and water use efficiency are better.According to the correlation analysis between water retention capacity and total yield of water retention agent,it can be seen that when the SAP addition ratio is 0.455%,the total yield reaches the maximum.Therefore,it is recommended that the proportion of SAP added in the production of Pleurotus ostreatus is 0.3%~0.455%. |
