Other claims from this paper (10)
- Intervention effect Saline water with ECiw at 3.4 dS·m−1 gave no significant difference in grain yields compared with the CK treatment.
- Observation Soil salt accumulated in winter wheat seasons could be leached from the main root zone in the following summer maize seasons.
- Intervention effect The difference in soil properties between ECiw 3.4 dS·m−1 and the CK treatment was not apparent.
- Association Electrical conductivity of the saturated soil extract, soil pH and sodium adsorption ratio in the top 0-30 cm layer increased with ECiw.
- Association Bulk density in the top 0-30 cm layer increased with ECiw.
- Association Soil organic carbon, porosity and macroaggregates content in the top 0-30 cm layer decreased with ECiw.
- Association Activities of catalase, urease and alkaline phosphatase in the top 0-30 cm layer decreased with ECiw.
- Intervention effect Relative grain yields were reduced by below 5% with ECiw lower than 3.17 dS·m−1 compared with CK.
- Intervention effect Soil quality index was reduced by below 5% with ECiw lower than 3.10 dS·m−1 compared with CK.
- Recommendation ECiw of 3.10 dS·m−1 is recommended as the safe utilization threshold for long-term saline water irrigation in the NCP.
