The Study of Soil Improvement in the Process of Land Consolidation in Salinization Area

Abstract:

According to the consolidation practice and the special characteristics of land in the saline area with high soil salt content and less nutrient content, this article adopted salt separated material (A), the depth of the salt separated material (B) and amendments (C) as factors to improve the soil property by designing 3 factors of 3 level orthogonal variance analysis. Based on it, the better drainage scheme can be chosen and it can provide guidance on land consolidation in the region. The results showed that: after soil improvement, the soil bulk density, pH and salt content decreased significantly, the content of effective nitrogen, phosphorus and organic matter showed an upward trend, but a slight decline in effective potassium. Compared with the control group, the soil properties, mainly nutrients, crop biomass and yield significantly of the test groups were significantly improved, and the indicators were significantly different. After comprehensive consideration, the best improvement program is A2B2C1, and the slag and straw, 60cm and organic fertilizer are selected as the salt separated material, the depth of the salt separated material and amendments respectively.
