| Abstract: |
| 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. |
