| 为了探究木醋液及其配施螯合钙对新疆盐碱土土壤性质和棉花幼苗生长的影响，采用室内盆栽试验，共设7个处理，即施加蒸馏水（CK）、施加木醋液150（M1）、300 （M2）、600 kg·hm-2（M3）,施加木醋液+螯合钙150 （T1）、300（T2）、600 kg·hm-2（T3）。结果表明：（1）与对照相比，施加木醋液、木醋液配施螯合钙处理均可以显著降低土壤水溶性总盐的含量，降低了8.75%~54.10%；土壤速效磷（Available-P）含量显著增加了32.25%~86.95%，土壤速效钾（Available-K）含量显著增加了8.80%~14.96%，土壤多酚氧化酶（S-PPO）和土壤碱性磷酸酶（S-AKP）的含量分别显著增加5.16%~16.65%和3.08%~45.90%，棉花幼苗的株高、茎粗以及鲜质量分别增加了5.66%~53.81%、9.80%~45.61%以及3.21%~124.78%。（2）与单施木醋液相比，木醋液配施螯合钙处理能够有效促进土壤水溶性总盐的降低，最低为3.54 g·kg-1，较CK降低了54.10%；土壤速效磷和土壤速效钾含量均在T2处理下最高，分别为65.30 g·kg-1和174.00 g·kg-1，与CK相比分别增加了88.10%、19.70%；S-AKP活性在T3处理时最强，较CK增加了45.90%；棉花幼苗的株高、茎粗以及鲜质量均在T2处理最高，分别为8.60 cm、11.80 mm以及3.27 g。（3）通过熵权法分析得出，木醋液配施螯合钙比单施木醋液改良盐碱土效果好，T2处理优于其他处理，综合排名第一。其最佳施用量是300 kg·hm-2。 |

| In order to investigate the impacts of wood vinegar liquid and its combined application with chelated calcium on the properties of saline\|alkali soil in Xinjiang and the growth of cotton seedlings, an indoor pot experiment was carried out. A total of seven treatments were set up, namely the application of distilled water (CK), the application of wood vinegar liquid at 150 (M1), 300 (M2), and 600 kg·hm-2 (M3), and the application of a combination of wood vinegar liquid and chelated calcium at 150 (T1), 300 (T2), and 600 kg·hm-2 (T3). The results showed that, (1) Compared with the control group, both the application of wood vinegar liquid and the combined application of wood vinegar liquid and chelated calcium could significantly reduce the content of water\|soluble total salt in the soil, with a reduction range of 8.75%~54.10%. The content of soil available phosphorus (Available-P) increased significantly by 32.25%~86.95%, and the content of soil available potassium (Available-K) increased significantly by 8.80%~14.96%. The contents of soil polyphenol oxidase (S-PPO) and soil alkaline phosphatase (S-AKP) increased significantly by 5.16%~16.65% and 3.08%~45.90%, respectively. The plant height, stem diameter, and fresh weight of cotton seedlings increased by 5.66%~53.81%, 9.80%~45.61%, and 3.21%~124.78%, respectively. (2) In comparison with the sole application of wood vinegar liquid, the combined application of wood vinegar liquid and chelated calcium could effectively promote the reduction of water\|soluble total salt in the soil. The lowest content was 3.54 g·kg-1, which was 54.10% lower than that of CK. The contents of soil available phosphorus and soil available potassium were the highest under the T2 treatment, reaching 65.30 g·kg-1 and 174.00 g·kg-1, respectively, showing an increase of 88.10% and 19.70% compared with CK. The activity of S-AKP was the highest under the T3 treatment, increasing by 45.90% compared with CK. The plant height, stem diameter, and fresh weight of cotton seedlings were the highest under the T2 treatment, measuring 8.60 cm, 11.80 mm, and 3.27 g, respectively. (3) Through the entropy weight method analysis, it was found that the combined application of wood vinegar liquid and chelated calcium had a better effect on improving saline\|alkali soil than the sole application of wood vinegar liquid. The T2 treatment was superior to other treatments, ranking first in the comprehensive evaluation. The optimal application rate was 300 kg·hm-2. |
