“…When residue return was conducted 3, 4, and 5 times, fruit yield remarkably increased by 8.24%, 7.53% and 8.23% at the 4th, 5th, and 6th pre-returning stages, respectively (Figure 5a). Similar promotion was also found in crop straw return [49,50] and compost addition [23,51]. This result might be attributed to the high dry weight of vegetable residue returned to the soil at the 4th pre-returning stage and the continuous improvement of soil physicochemical characteristics.…”

The tremendous scale of protected vegetable cultivation incidentally produces considerable vegetable residue, which refers to the remaining parts of plants after the final harvest. The low use rate of vegetable residue results in nutrient waste and environmental pressure in China. In this study, we put forward vegetable residue directly returned to the soil and investigated its feasibility. Residue return was steadily conducted 5 times in a Chinese solar greenhouse with the cucumber–tomato rotation pattern. Results showed that residue return increased the soil alkali-hydrolysed nitrogen and available potassium contents by 4.97–26.22% and 9.31–21.92%, respectively, along with slightly reduced soil pH and bulk density by 1.00–5.39% and 6.72–11.81%, respectively. Gemmatimonadetes, Firmicutes, Acidobacteria, Basidiomycota, and Mortierellomycota were the major phyla with noticeable changes when residue return was conducted 5 times. Fruit yield began to obtain remarkable increase by 5.81–9.26 t·ha−1 after residue return was conducted 3 times, bringing about additional profits of 5382.0–8519.2 USD·ha−1. Residue return could cut down the disposal expense of vegetable residues by 480.89 USD·ha−1. Moreover, residue return could supplement nutrients to soil, potentially contributing to reducing chemical fertilizer inputs. In conclusion, in situ vegetable residue return could be considered to be a feasible and sustainable use technique for vegetable residues in the Chinese solar greenhouse.

“…CK, soil without any amendment as a control; BC + W0, soil amended with bone char and distilled water; BC + W1, bone char + irrigation water from well 1; BC + W2, bone char + irrigation water from well 2; and BC + W3, bone char + irrigation water from well 3. Vertical bars indicate the standard error of the mean (n = 3 replicates) the soil solution compared to the freshwater (Cao et al 2019;Li et al 2019). The concentrations of soluble chloride and sulfate in soil solution increased with an increase in soil salinity as a result of using saline water irrigation (Chen et al 2019;Li et al 2019).…”

“…High salt stress limits the use of water, accompanied by cytotoxicity and imbalance of nutrient absorption, thus limiting the growth and development of roots, stems and leaves; In addition, sodium ions will also have a negative impact on nutrient absorption, usually leading to nutrient deficiency. The accumulation of Na in the cytoplasm or vacuole will disturb the K + /Na + homeostasis, thereby reducing the K + /Na + ratio in the cytoplasm; Excessive Na + and Cl - will lead to ion imbalance, and induce K + deficiency due to cell membrane damage, resulting in blocked oxidation process in cells, leading to interference with photosynthetic mechanism, growth rate and biomass ( Hafsi et al., 2017 ; Khoshbakht et al., 2018 ; Cao et al., 2019 ; Guo et al., 2020 ). Mild or moderate salt stress can increase the thickness of cell wall to reduce the accumulation of such potentially toxic ions; However, at high concentrations, it affects cell expansion and cell wall integrity, leading to damage to protective tissues, such as epidermis and endoderm ( Silva et al., 2021 ; Sousa et al., 2021 ).…”

This study investigated the effects of exogenous 2, 4-epibrassinolide lactone (EBR) on the growth, photosynthetic pigments, antioxidant defense system, ion homeostasis, MAPK cascade and key genes of SOS signaling pathway of cucumber seedlings under salt stress using cucumber “Xinchun 4” as the test material. The experiment was set up with four treatments: foliar spraying of distilled water (CK), 50 mmol.L-1 NaCl (NaCl), 50 mmol.L-1 NaCl+foliar spray of 0.02 μmol.L-1 EBR (EBR+NaCl), and 50 mmol.L-1 NaCl+foliar spray of 24 μmol.L-1 Brassinazole (BRZ) (BRZ+NaCl). The results showed that EBR+NaCl treatment significantly increased plant height, above-ground fresh weight, total root length, total root surface area, average rhizome and photosynthetic pigment content compared to NaCl treatment. Meanwhile, compared with NaCl treatment, EBR+NaCl treatment significantly increased superoxide dismutase, catalase and ascorbate peroxidase (SOD, CAT and APX) activities, significantly promoted the accumulation of osmoregulatory substances (soluble sugars and proline), and thus effectively reduced malondialdehyde (MDA) content and relative electrical conductivity of cucumber leaves. Exogenous spraying of EBR also significantly reduced Na+/K+ under NaCl stress, effectively alleviating the toxic effects of Na+ ions. In addition, exogenous EBR induced the up-regulated expression of CsMAPK3, CsMAPK4, CsMAPK6 and CsMAPK9 genes in the MAPK cascade signaling pathway and CsSOS1, CsSOS2 and CsSOS3 genes in the SOS signaling pathway to enhance salt tolerance in cucumber under NaCl stress. Therefore, exogenous spraying EBR may effectively reduce the damage of salt stress on cucumber seedlings by improving antioxidant capacity, maintaining ion homeostasis and activating salt-tolerant related signaling pathways, which might promote the growth of cucumber seedlings and the establishment of root system morphology. This study provides a reference for EBR to improve the salt tolerance of cucumber.
