内蒙古东部区玉米草谷比与秸秆可收集系数监测

Monitoring of Corn Grass to Grain Ratio and Straw Collectability Coefficient in the Eastern Region of Inner Mon⁃golia

为丰富内蒙古东部区玉米草谷比与可收集系数测算样本数量,进一步完善秸秆资源台账数据,科学测算玉米秸秆资源量,在内蒙古东部区开展玉米草谷比与秸秆可收集系数监测试验。通过对呼伦贝尔市阿荣旗、兴安盟扎赉特旗、通辽市科左中旗、赤峰市阿鲁科尔沁旗等4个旗县20个行政村12个苏木乡镇进行监测试验,结果表明,实测玉米草谷比为1.06~1.49,平均值为1.25;玉米秸秆可收集系数为0.78~0.86,平均值为0.82,数据可为内蒙古东部区秸秆资源化利用提供数据支撑。

In order to enrich the sample size of corn grass to grain ratio and collectible coefficient calculation in the eastern region of Inner Mongolia,further improve the straw resource ledger data,and scientifically calculate the amount of corn straw resources,monitoring experiments on corn grass to grain ratio and collectible coefficient were carried out in the east⁃ern region of Inner Mongolia.Through monitoring experiments on 20 administrative villages and 12 Sumu townships in 4 banner counties,including Arong Banner in Hulunbuir City,Zhalaite Banner in Xing'an League,Kezuo Middle Banner in Tongliao City,and Aruhorqin Banner in Chifeng City,the results showed that the measured corn grass to grain ratio was 1.06~1.49,with an average value of 1.25;The collectible coefficient of corn straw is 0.78~0.86,with an average value of 0.82.The data can provide data support for the resource utilization of straw in the eastern region of Inner Mongolia.
