麦秸不同部位生物降解速率差异
The Differences of Biodegradation Rates in the Different Parts of Wheat Straw
摘要
Abstract
Decomposing experiment was carried out to study the decomposition rates of different parts of wheat straw by adding Streptomyces rochei with a period of 27 d under the room temperature and flooding conditions. Physical and chemical indexes such as the rate of dry mat-ter, the activity of cellulose enzyme, the number of experimental fungus, fiber composition and crystallinity, and total phenolic acid were mea-sured and analyzed in different parts of straw leaves, sheaths, cobs, stems and roots. Results indicated that Streptomyces rochei became the dominant strains under the flooded environment. Wheat straw decomposing speed of different parts were:leaves>sheaths>cobs>roots>stems. Loss rate of dry matter and cellulose enzyme activity, cellulose enzyme activity and total phenolic acids had significant positive correlation at 0.01 level. Meanwhile, loss rate of dry matter and total phenolic acids were also positively correlated. The decomposing rates of cobs, stems and roots were slower than others, and they were accounted for a relatively large proportion of the whole wheat straw. According to the con-clusion, using the inoculum favorable wheat straw decomposition, inoculants should be inoculated into the stems and cobs site to speed up the decomposing of straw. It also could provide the scientific basis for resource utilization and determine a fixed position on the harvester for vac-cination equipment.关键词
