| Abstract: |
| Taking the 6-year-old wine grape, Cabernet Sauvignon, which is mainly planted in Helan Mountain foothill of Ningxia, as the research object, the natural grass (CZR) and artificially planted purslane (CMC) were carried out continuously for 2 years, and clean tillage (CK) was used as a control. The effects of intra\|row planted grass on soil temperature, bulk density, total porosity, fertility, enzyme activity, microbial quantity, and wine grape yield and quality were studied. The results showed that compared with CK treatment, the CZR treatment decreased the average soil temperature in 5~25 cm soil layer of young fruit stage, expanding stage, and mature stage by 0.94℃, 1.12℃, and 0.93℃, respectively, the average soil bulk density and total porosity in the 0~60 cm soil layer by 2.23% and 1.73%, respectively, and increased urease activity, invertase activity, alkaline phosphatase activity, and catalase activity significantly by 22.67%, 30.26%, 8.46%, and 66.65%, respectively and the number of total microorganism by 34.97%. The CMC treatment decreased the average soil temperature in the 5~25 cm soil layer at young fruit stage, expanding stage, and mature stage by 1.82℃, 2.02℃, and 1.38℃, respectively, and the average soil bulk density and total porosity in the 0~60 cm soil layer by 0.90% and 2.87%, respectively. The soil organic matter, available nitrogen, available phosphorus, available potassium, total nitrogen and total phosphorus increased by 37.80%, 52.67%, 31.73 %, 31.17%, 24.81% and 21.13%, respectively. Urease activity, invertase activity, alkaline phosphatase activity, and catalase activity significantly increased by 72.08%, 109.67%, 14.93%, and 154.50%, respectively, and the number of total microorganism increased by 103.56%. Intra\|row planted grass had no significant effect on the yield of wine grapes, and had significant effect on improving the quality of grape. The content of soluble solids in grapes with CZR treatment and CMC treatment was 1.33% and 3.72% lower than that of CK treatment. Titratable acid, tannin, total phenol, and anthocyanin content increased by 14.52% and 16.13%, 21.23% and 25.82%, 26.65% and 24.41%, 32.75% and 41.16%, respectively, compared with that of CK treatment. Under the drip irrigation conditions in the arid area, through the continuous 2 years intra\|row planted grass research found that the intra\|row planted grass improved the soil physical properties, enhanced the soil fertility, increased the soil enzyme activity and the number of microorganisms. The effect of intra\|row planted grass on the yield of wine grapes was not significant. In addition, intra\|row planted grass was beneficial to the accumulation of aroma components of wine grape, adjusted the ratio of sugar to acid, the best effect of intra\|row artificially planting purslane. |
