为了进一步丰富农作物草谷比、秸秆可收集系数测算样本集，提高草谷比、可收集系数的准确性与可靠性，完善秸秆资源台账。通过对环县曲子镇宋家塬、环城镇龚淌、环城镇十五里沟、八珠乡苟塬、洪德镇耿塬畔等5个行政村110块小麦田进行监测，结果表明，环县2022年小麦播种面积3.3万hm2，平均产量为2.25 t/hm2，总产量7.4万t，草谷比为1.05，秸秆可收集系数为0.86，秸秆产生量为7.77万t。秸秆可收集量为6.68万t。监测得出的数据是真实可靠的，能够准确反映环县2022年小麦秸秆产生量和可收集量。

In order to further enrich the calculation sample set of grass-grain ratio and straw collectable system, to improve the accuracy and reliability of grass-grain ratio and straw collectable coefficient, and to improve the straw resource ledger. 110 pieces of wheat farmlands in 5 villages of Quzi Township, Huancheng Township, Bazhu Township, and Hongde Township, Huanxian were monitored. Results showed that in 2022, Huanxian had a wheat planting area of 33 000 ha, an average yield of 2.25 t/ha, a total yield of 74 000 t, a grass-grain ratio of 1.05, a straw collectable coefficient of 0.86, a straw yield of 77 700 t, and a collectable straw yield of 66 800 t. The data obtained from this monitoring are reliable, which could accurately reflect the yield of wheat straw produced and collected in Huanxian in 2022.
