| 研究了不同醋糟、粉煤灰处理下高粱苗期土壤微生物数量和土壤酶特性的变化特征及对高粱生长的影响，以探讨醋糟、粉煤灰的施用效果及最佳配比，试验设置4个处理，分别是处理1（醋糟100%）、处理2（醋糟∶粉煤灰=1∶1）、处理3（醋糟∶粉煤灰=2∶1）、处理4（醋糟∶粉煤灰=3∶1）和化肥对照。结果表明：施用醋糟、粉煤灰可以有效增加土壤微生物数量和提高土壤酶活性，提高叶片光合速率和高粱产量。处理1~处理4细菌数量分别比对照提高19.66%、31.34%、15.69%、12.54%，放线菌数量分别比对照提高20.99%、32.37%、17.56%、10.43%，真菌数量分别比对照提高22.78%、34.26%、13.54%、9.56%；土壤磷酸酶活性分别比对照提高17.11%、20.85%、12.29%和19.78%；土壤蔗糖酶活性比对照提高了23.70%、37.08%、11.54%和3.08%，土壤脲酶活性比对照提高了25.28%、34.77%、19.82%和13.79%；处理2苗期光合速率分别比对照、处理1、处理3和处理4提高13.8%、6.67%、9.98%和13.30%，拔节期提高3.45%、3.22%、3.21%和4.05%，抽穗期提高14.52%、3.75%、1.86%和12.66%，灌浆期提高了13.08%、4.26%、4.08%和9.36%，成熟期提高了3.8%、1.05%、2.12%和2.20%。醋糟含有大量的有机物质和无机物质，可为土壤微生物的生命活动提供能量和养料，进而促进土壤微生物的繁殖和土壤酶活性。 |

| In order to understand the application effect and the best ratio of vinegar residue and fly ash in sorghum planting , the change characteristics of soil microbial and enzyme activity have been studied by field experiments. Test experiments. set up four treatments, treatment 1(100% vinegar), treatment 2(vinegar∶fly ash=1∶1), treatment 3(vinegar∶fly ash=2∶1), 4(vinegar∶fly ash=3∶1) and fertilizer treatment. The results showed that soil microbial and enzyme activity and leaf photosynthetic rate and yield were increased under the treatments of vinegar residue and fly ash. The percentage increase of bacteria number of treatments, from first to fourth, were 19.66%, 31.34%, 15.69% and 12.54%, respectively. The percentage increase of actinomycete number were 20.99%, 32.37%, 17.56%, 10.43% and the percentage increase of fungi number were 22.78%, 34.26%, 13.54%, 9.56%, respectively. The percentage increase of phosphatase from first to fourth, were 17.11%、20.85%、12.29% and 19.78%；The percentage increase of invertase from first to fourth, were 23.70%、37.08%、11.54% and 3.08%；The percentage increase of urease from first to fourth, were 25.28%、34.77%、19.82% and 13.79%； The photosynthetic rate of treatment 2 at seedling stage from CK to fourth, were13.8%, 6.67%, 9.98% and 13.30%, the photosynthetic rate at jointing stage from CK to fourth, were 3.45%, 3.22%, 3.21% and 4.05% the photosynthetic rate at heading stage from CK to fourth, were 14.52%, 3.75%, 1.86% and 12.66%; the photosynthetic rate at filling stage from CK to fourth, were 13.08%、4.26%、4.08% and 9.36%；the photosynthetic rate at mature stage from CK to fourth, were 3.8%、1.05%、2.12% and 2.20%.To sum up, vinegar residue contains a large number of organic and inorganic substances, which can provide energy and nutrients for the life activities of soil microorganisms, thereby promoting the reproduction of soil microorganisms and soil enzyme activities. |
