由于玉米秸秆的环保再利用受到越来越多的关注,利用玉米秸秆作为饲料是一种有效可行的方法。然而,无论是纤维素,木质素,玉米秸秆中的半纤维素可以有效地分解成为玉米秸秆作为饲料的关键。通过五个不同的降解温度(22°C,24°C,26°C,28°C,30°C),五个不同的pH值(4,5,6,8,10),和五个不同的降解持续时间(5、15、25、30和35天)来检查25种不同的降解条件。发现半纤维素的分解效果,纤维素,还有木质素,第25组(26°C,pH=5,25天)与其他组相比更强,含量计算为8.22%,31.55%,分别为22.55%(p<0.01,p<0.05)。第19组(22°C,pH=4,5天)显示纤维素的降解效果最差,木质素,和半纤维素与其他组相比,含量计算为15.48%,38.85%,和29.57%,单独(p<0.01,p<0.05)。研究数据为玉米秸秆降解的理想降解条件提供了基础,并结合了P.chrysosporium和O.furacalis幼虫的消化酶。旨在探索一种高效环保的玉米秸秆降解方法。
Since the environmentally friendly reuse of corn stalks attracts more and more attention, it is an efficient and feasible way to reuse corn stalks as forage. However, whether the cellulose, lignin, and hemicellulose within corn stalks can be effectively decomposed becomes a key to reusing corn stalks as forage. Orthogonal test was designed by five different degradation temperatures (22°C, 24°C, 26°C, 28°C, 30°C), five different pH values (4, 5, 6, 8, 10), and five different degradation time durations (5, 15, 25, 30, and 35 days) to examine 25 kinds of different degradation conditions. It was found that the decomposition effect of hemicellulose, cellulose, and lignin, of group 25 (26°C, pH = 5, 25 days) was stronger compared with other groups, with the contents calculated as 8.22%, 31.55%, and 22.55% individually (p < 0.01, p < 0.05). Group 19 (22°C, pH = 4, 5 days) revealed the worst degradation effect of cellulose, lignin, and hemicellulose compared to other groups, with contents calculated as 15.48%, 38.85%, and 29.57%, individually (p < 0.01, p < 0.05). The research data deliver a basis for ideal degradation conditions for corn stalks degradation in combination with the digestive enzymes of P. chrysosporium and O. furnacalis larva. Aiming to explore a highly efficient and environmentally friendly corn stalk degradation method.
