| 摘 要： | 利用木霉菌产纤维素酶的能力，降解秸秆，有利于还田，减少生物质能源的浪费。通过连续多次提取木霉菌，以秸秆降解率为指标，研究木霉菌对秸秆降解能力。以秸秆失重率，秸秆中N、P、K中含量变化为指标，通过多次提取木霉菌，提高了其降解秸秆能力，提取到第4 次时，木霉对秸秆的降解率为最高，当提取到第5次时秸秆降解率略有下降，到第6次时下降最为明显。多次提取木霉菌，可能提高木霉菌降解秸秆的能力，但不是次数越多越好，以4次为宜。

Effects of Trichoderma harzianum on Wheat Straw Degradation |
| |
| Abstract: | Using Trichoderma harzianum for producing cellulose enzyme to degrade straw was advantageous to returning straw to field and reducing the waste biomass. Trichoderma was extracted continuously. Straw degradation rate was used as indicators to research straw degradation ability. With straw weightlessness rate, and changes in the N, P, K content in the straw as indexes, through multiple extractions, the ability of straw degradation was improved. To the fourth extraction, effect of trichoderma viride on straw degradation rate was the highest, to the fifth extraction, straw degradation rate fell slightly, and to the sixth extraction, the decline
was most obvious. Multiple extractions could improve the ability of trichoderma in straw degradation, but not the more the better, with four times as advisable. |
