农作物秸秆的生物高效综合利用已成为研究的热点,实施秸秆还田技术不仅使粮食产量增加6%-15%,而且由于逐步增加了土壤肥力,实现大面积以地养地、促进粮食产量的持续增加。在我国,秸秆还田技术已经被农业部大力推广,作为增肥改土工程和环保农业的重要技术,近几年取得了较快的发展。秸秆的快速腐解是秸秆还田的关键技术,重点研究秸秆复合菌系来快速降解秸秆具有非常重要的意义。虽然许多学者对分解秸秆的纤维素酶菌株的选育做了大
The efficient and comprehensive utilization of crop stalks has become a research hotspot. The implementation of straw returning technology not only increased the grain yield by 6% -15%, but also increased grain yield as a result of gradual increase of soil fertility and large areas of land increase. In our country, the technique of returning straw to straw has been vigorously popularized by the Ministry of Agriculture. As an important technique for soil improvement and environmental protection in the fields of fertilizer and fertilizer, rapid development has been achieved in recent years. The rapid decay of straw is the key technology of straw returning. It is very important to focus on straw compound strains to rapidly degrade straw. Although many scholars have done large selection of cellulase strains that decompose straw
