| Abstract: |
| In order to better understand the impacts of different organic fertilizers on soil organic matter, enzyme activity, microorganisms, and wine grape production, a field experiment was conducted and 5 a raw Cabernet Sauvignon wine grapes were used as test materials to study the effects of different organic fertilizers on soil organic matter, enzyme activity, and microorganisms in soil layers of 0~20, 20~40 cm, and 40~60 cm. The treatments included none\|organic fertilizer as the control (CK), biogas residue (BR), sheep manure (SMOF), cow manure (CMOF), pig manure (PMOF), and cow manure + biogas residue organic fertilizer (CMOF+BR). The results showed that compared with CK after application of different organic fertilizers, soil organic matter content increased by 6.79%~44.97%, soil microbial carbon increased by 19.78%~91.53%, microbial nitrogen increased by 2.22~3.93 times, and alkaline phosphatase increased by 57.78%~512.55%, catalase increased by 53.45%~240.48%, the grape yield increased by 15.12%~46.89%. Compared with other organic fertilizers treatments, the organic matter content of cow manure applied in different soil layers increased by 8.49%~33.29%; the content of microbial carbon and nitrogen in the soil increased by 5.30%~42.46% and 6.12%~49.65%, respectively; alkaline phosphatase increased by 8.01% to 184.63%, catalase increased by 5.14% to 84.27%, urease increased by 25.58% to 410.70%, invertase increased by 6.00% to 107.65%, and the total number of microorganisms increased by 5.99% to 56.56%. Compared with other organic fertilizers in this experiment, the application of organic manure from cow dung increased the yield by 7.08%~27.60%. It showed that the application of organic fertilizer in Ningxia area effectively increased the content of soil organic matter, increased the number of microorganisms, enhanced soil enzyme activity, promoted the growth and development of wine grapes, and increased yield. Among them, cow manure had the most significant effect. |
