中文摘要:
      为制定合理的盐碱化土壤改进措施，提升棉花产量和水分利用效率，设置2种滴灌方式：未加气常规滴灌（A0）和加气滴灌（A1），4种生物炭施用量：0、12、24、36 t·hm-2（B0、B12、B24、B36），研究加气滴灌和生物炭对盐碱土理化性质和棉花产量的影响。结果表明：随生物炭用量增加，土壤容重逐渐降低，较B0处理平均降低8.63%;土壤孔隙度、pH值、含盐量逐渐增加，增幅分别为12.57%、2.62%、11.72%;土壤含水量呈先增后减趋势，B24处理增幅最大，达19.24%。A1处理较A0处理土壤容重、含水量、pH值和含盐量分别平均降低4.71%、9.27%、0.82%、4.65%，土壤孔隙度平均增加6.19%。加气滴灌和生物炭共同作用下，棉花产量平均提高17.17%、水分利用效率平均提升13.55%。
英文摘要:
      In order to formulate reasonable improvement measures for saline\|alkali soil and improve cotton yield and water use efficiency, two drip irrigation methods were set up: unaerated conventional drip irrigation (A0) and aerated drip irrigation (A1), and four biochar application rates: 0, 12, 24, and 36 t·hm-2 (B0, B12, B24, and B36). The effects of aerated drip irrigation and biochar on the physical and chemical properties of saline\|alkali soil and cotton yield were studied. The results showed that with the increase of biochar dosage, the soil bulk density decreased gradually, which was 8.63% lower than that of the B0 treatment. The soil porosity, pH value, and salt content increased gradually, with an increase of 12.57%, 2.62%, and 11.72%, respectively. The soil water content increased first and then decreased, and the increase of the B24 treatment was the largest, reaching 19.24%. Compared with the A0 treatment, the soil bulk density, water content, pH value, and salt content of the A1 treatment decreased by 4.71%, 9.27%, 0.82%, and 4.65%, respectively, and the soil porosity increased by 6.19% on average. Under the combined action of aerated drip irrigation and biochar, the cotton yield increased by 17.17% on average, and the water use efficiency increased by 13.55% on average.
