秸秆还田后颜色由浅变深是反映秸秆腐解程度的重要指标之一。为了快速准确地识别小麦秸秆的分解程度，建立了一种基于土壤中不同天数降解的秸秆颜色的高通量定量图像分析方法。并研究了这些值与秸秆中化学成分含量的相关性。结果表明，代表秸秆颜色的灰度值与秸秆中残留灰分含量呈极显著负相关(R2=0.0.696)。利用该方法对秸秆分解过程中的微生物菌剂进行了研究。结果表明，接种微生物的秸秆在30d后的灰度值与未接种微生物的秸秆有显著差异。添加微生物接种剂的秸秆最终色泽比未接种剂的要深得多。这表明微生物接种剂不仅可以加快麦草在土壤中的分解速度，还可以影响其最终的矿化程度。
The colour of straw changing from lighter to darker after being incorporated into soil is one of the most important reflections of the degree of straw decomposition. To quickly and accurately identify the decomposition degree of wheat straw, a high-throughput quantitative image analysis method was developed based on the colour of the straw degraded in soil over a different number of days. The correlation between these values and the contents of the chemical components in the straw was also investigated. The results indicated that the grey value representing the colour of the straw had a significant negative correlation with the content of residual ash in the straw (R2= 0.696). The method was used to study the microorganism inoculants involved in straw decomposition. The results showed that there was a significant difference between the straw with and without microorganism inoculants in terms of the grey value after 30 days. The final colour of the straw with microorganism inoculants was much deeper than that of straw without inoculants. This suggests that the microorganism inoculants not only could accelerate the decomposition speed of the wheat straw incorporated into the soil but could also affect its final degree of mineralization.
