Abstract
Soil salinization is one of the main reasons for soil degradation, which limiting the improvement of soil productivity. To evaluate the response plant height, stem diameter, plant biomass and nutrient uptake of maize, and soil properties to various salt stress and oxygen supply rates, a soil culture experiment with two factors were carried out: different salt stress degrees (A0, 0 g L−1 NaCl irrigation; A3, 3 g L−1 NaCl irrigation; A6, 6 g L−1 NaCl irrigation; A9, 9 g L−1 NaCl irrigation;) and different rhizosphere oxygen supply degrees (B0, 0 ml L−1 H2O2 solution; B0.5, 0.5 ml L−1 H2O2 solution; B1, 1 ml L−1 H2O2 solution; B1.5, 1.5 ml L−1 H2O2 solution). The results showed that the plant height, stem diameter, aboveground and root biomass of maize under different salt stress degrees were reduced by 6.8–9.8%, 4.4–9.8%, 18.4–45.5% and 21.4–35.8% at the end of the experiment compared to A0, respectively. Meanwhile, the nutrient uptake of aboveground and root were declined, especially under high salt stress degree, but the sodium (Na+) uptake was increased significantly. Rhizosphere oxygen supply enhanced the plant height, stem diameter, aboveground and root biomass by 2.0–6.5%, 4.1–6.1%, 27.5–56.6% and 19.5–47.1% at the end of the experiment compared to B0, respectively. The restriction of nutrient absorption caused by salt stress could be alleviated. Soil quality indicators were influenced by salt stress and oxygen supply management as well. Overall, rhizosphere oxygen supply could alleviate the restriction of salinization on maize growth at seedling stage, improve soil chemical quality and water use efficiency.
