| 为探究关中地区最佳的猕猴桃果园覆盖模式，以3年生‘徐香’猕猴桃为试验材料，设置3种覆盖方式：行内覆地布+行间生草（FG）、行内覆地布+行间裸地（FN）和行内裸地+行间生草（NG），以行内裸地+行间裸地（NN）作为对照，分析不同覆盖方式对猕猴桃各生育时期土壤储水量、果实形状、产量及品质的影响，同时运用熵权法对猕猴桃三类果实指标（果实产量、生长及品质）进行评价，并采用TOPSIS法对各覆盖处理进行综合评价。结果表明，二元覆盖（FG）可以同时增加猕猴桃行内与行间土壤储水量，与对照（NN）相比，其全生育期行内储水量分别增加10.06%（2021）和38.19%（2022），行间储水量分别增加3.97%（2021）和3.89%（2022）；二元覆盖（FG）显著增加了猕猴桃果实体积（两年增幅分别为24.18%和24.54%）、可溶性固形物含量（8.06%和10.89%）、可溶性糖含量（17.79%和14.08%）和固酸比（22.80%和20.16%），显著降低果实中可滴定酸含量（两年降幅分别为13.25%和8.47%）。不同覆盖模式对猕猴桃产量指标（单株结果数、单果质量和单株产量）的影响基本相同，整体表现为FG＞FN＞NG＞NN。利用熵权法对猕猴桃各指标赋权，其中权重最大的指标为可溶性糖含量，两年分别为0.3032（2021）和0.2450（2022），猕猴桃单株产量与果实体积权重次之；TOPSIS法计算表明，贴合度（Ci）最大的处理为二元覆盖（FG），最有利于关中地区猕猴桃果实生长。综上，行内覆地布＋行间生草可作为关中地区猕猴桃果园适宜的覆盖模式进行推广应用。 |

| In order to investigate the optimal kiwifruit mulching pattern in kiwifruit orchards in Guanzhong region, an experiment utilized three\|year\|old ‘Xuxiang’ kiwifruit plants was carried out under three different ground mulching treatments: intra\|row fabric + inter\|row grass mulching (FG),intra\|row fabric + inter\|row bare ground (FN),intra\|row bare ground + inter\|row grass mulching (NG),and intra\|row bare ground + inter\|row bare ground (NN) as the control, to analyze the effects of different mulching methods on the soil water storage, fruit shape, yield and quality of kiwifruit in each reproductive period. The entropy weight method was applied to evaluate the three types of kiwifruit fruit indicators (fruit yield, growth, and quality),and the TOPSIS method was used to comprehensively evaluate each mulching treatment. The results showed that the dual mulching method (FG) could simultaneously increase soil water storage both within and between kiwifruit rows. Compared with the control (NN) treatment,soil water storage within rows increased by 10.06% (2021) and 38.19% (2022),while soil water storage between rows increased by 3.97% (2021) and 3.89% (2022)in treatment FG throughout the entire growth period. The dual mulching method (FG) significantly enhanced kiwifruit fruit volume (increase rate of 24.18% and 24.54% in 2021 and 2022 respectively), soluble solid content (8.06% and 10.89%),soluble sugar content (17.79% and 14.08%), and the solid\|acid ratio (22.80% and 20.16%) over the two years,while significantly reducing titratable acid content (decrease rate of 13.25% and 8.47% in 2021 and 2022 respectively). The effects of different mulching methods on the three yield indicators of kiwifruit (number of fruit per plant, single fruit quality, and yield per plant) were generally consistent,with the order of effectiveness being FG > FN > NG > NN. Using the entropy weight method to assign weight to each indicator of the kiwifruit, the highest weight was assigned to soluble sugar content,with values of 0.3032 (2021) and 0.2450 (2022), followed by single\|plant yield and fruit volume. According to the TOPSIS method,the dual mulching method (FG) had the highest closeness coefficient (Ci), indicating that it is the most conducive to kiwifruit growth in the Guanzhong region. In summary,the mulching mode of intra\|row fabric + inter\|row grass mulching can be promoted and used in kiwifruit orchards in the Guanzhong area. |
