ABSTRACT

Soil salinisation can lead to soil compaction and fertility decline, which is unfavourable to crop nutrient absorption and hinders crop growth. In order to reduce its adverse effects on plant growth, tomato No.4 and 202 were used as experimental materials, AM fungi and Bacillus subtilis were used as inoculants, and three treatments of Gm, B, Gm + B and CK were established by soil inoculation and rooting method. Each group corresponded to three concentrations of salt solution (15, 75 and 150 mmol / L) for rooting, a total of 12 groups. The physiological changes of tomato and the differences of soil physical and chemical properties after 7d, 14d and 21d were studied. The results showed that the addition of AM fungi and Bacillus subtilis could promote plant height and root length development, and increase the activities of antioxidant enzymes, of which the maximum growth rates of SOD, POD, and CAT were 12.8%, 112.1%, and 30.6%, respectively, and the maximum reductions of MDA and Pro contents were 44.38% and 42.39%. In addition, the synergistic interactions between the two biocontrol bacteria inoculated made the saline soil pH decrease, the water content increase significantly, the N, P, and K contents increase in general, and the soil enzyme activities increased, which alleviated the problems of soil compaction and low fertility.
