“…Notably, this yield was achieved under deficit irrigation (irrigation quota: 1,760 m 3 /hm 2 ), and would be expected to increase significantly under appropriate agronomic management, such as the supply of appropriate nitrogen and/or adequate water (X. Wang et al., 2021 ). These results show that S. salsa can produce substantial biomass for use as a potential source of forage.…”

Plant growth, salt removal capacity, and forage nutritive value of the annual euhalophyte Suaeda salsa irrigated with saline water

Sustainable agricultural development in semiarid and arid regions is severely restricted by soil and water salinization. Cultivation of the representative halophyte Suaeda salsa, which can be irrigated with saline water and cultivated on saline soils, is considered to be a potential solution to the issues of freshwater scarcity, soil salinization, and fodder shortage. However, the salt removal capacity and differences in the forage nutritive value of S. salsa under different saline water treatments remain unknown. Using the methods of field trials and randomized blocks design, we quantified salt accumulation in the aboveground biomass, and the biochemical and nutritive value of field-cultivated S. salsa in arid northwestern China under irrigation with water of different salinities [i.e., freshwater or water containing10, 20, 30, or 40 g/L NaCl). The fresh and dry weights of S. salsa increased, then decreased, with increase in salinity. The salt content of the plant’s aboveground biomass increased to a constant range and, thus, the salt extraction of S. salsa was relatively stable under different salinities of irrigation water. Under the experimental conditions, the crude protein content significantly increased to 9.45% dry weight (DW) and then decreased to 6.85% DW, with an increase in salinity (p < 0.05). The neutral detergent fiber (42.93%–50.00% DW) and acid detergent fiber (34.76%–39.70% DW) contents were suitable for forage. The contents of trace elements, such as copper and zinc, were significantly increased after irrigation with saline water (p < 0.05). The forage of S. salsa is of high nutritive value for livestock, and contains low concentrations of anti-nutrients. Therefore, S. salsa can be considered for cultivation in saline soils irrigated with saline water. In addition, it provides a viable additional source of fodder in arid regions, where the availability of freshwater and non-saline arable land is limited.

Soil aggregate characteristics and enzyme activities are key to the sustainable development of soil quality management. However, there are presently few studies on soil aggregate nutrients, enzyme activities, and their driving factors in areas with karst rocky desertification. As such, this study investigated the effects of planting patterns on soil aggregate nutrients and soil enzyme activities under six typical planting patterns (walnut, Rosa roxburghii Tratt, ryegrass, walnut-Rosa roxburghii Tratt, Rosa roxburghii Tratt-ryegrass and walnut-ryegrass) in the karst rocky desertification area of plateau mountains. The results indicated that: (1) there were significant differences in soil aggregate nutrients and soil enzyme activities among the different plots, when compared to traditional farmland, the increase in the aggregate nutrient content and soil enzyme activities was most noticeable in walnut-Rosa roxburghii Tratt, Rosa roxburghii Tratt-ryegrass, and walnut-ryegrass, and the nutrients gradually increased as the aggregate particle size decreased. The maximum C:N and C:P ratios were measured in the 0.25-2 mm aggregates, while the maximum N:P ratios was measured occurred in the <0.053 mm aggregates. (2) The stoichiometric ratios had different degrees of relevance associated with the aggregate nutrients, TN and C:N, SOC and C:P, and TP and N:P showed extremely significant linear correlations. Moreover, a significant correlation also occurred between enzyme activity and aggregate nutrients, particularly in macroaggregates. (3) Soil physicochemical properties, such as the soil total porosity, capillary water holding capacity, saturated hydraulic conductivity, bulk density and pH, had a direct influence on enzyme activity, therefore, the soil condition can be improved by changing the planting patterns to promote enzyme activity. These findings are helpful for the optimal allocation of forest and grass for the comprehensive control of karst rocky desertification.
