摘要
在水稻 西瓜轮作模式中研究纤维素分解菌剂对水稻秸秆田间降解效果的影响。结果表明水稻秸秆还田中应用纤维素分解菌剂可以显著降低水稻秸秆的强度 ,增加土壤转化酶、脲酶、多酚氧化酶和纤维素酶的活性。应用纤维素分解菌剂在不同时期可以增加秸秆的降解率 5 .5 %～ 10 .7% ,增加下季作物西瓜产量6 .0 %～ 10 .0 %和糖度 9.1%～ 11.9%。秸秆应用纤维素分解菌剂还田是合理利用秸秆资源 ,用地养地 ,促进农业可持续发展的重要途径 ,是解决秸秆问题的根本出路。
In the rotation experiment of rice-watermelon, it w as found that applying cellulose-decomposing microbes could significantly decre ase the straw strength and increase the straw decomposition rate by 5.5%～10.7 % at different stages. At the same time applying cellulose-decomposing microb es could increase the activities of soil cellulase, invertase, urease and polyph enol oxidase and improve the soil quality. In the experiment, applying cellulose -decomposing microbes could also increase the following crop watermelon yield b y 6.0%～10.0%. So applying cellulose-decomposing microbes in returning straws t o field is a reasonable way to reuse straws resource.
