Abstract

The invention discloses a saline-alkali land comprehensive improving system and belongs to the technical field of saline-alkali land improvement. The saline-alkali land comprehensive improving system comprises a latticed saline-alkali land with a cofferdam, a moisture separation layer, salt-controlling and permeation-increasing closed conduits and water collection pipes, wherein trapezoidal soil stacks and inverted-trapezoidal trenches are plowed on the saline-alkali land; salt-controlling and permeation-increasing holes, water collection holes and detection scaleplates are drilled on the land; non-woven fabric filtering material is arranged on the salt-controlling and permeation-increasing pipes; and a water inlet hole is formed in ach water collection pipe. The invention further provides an improving method for the improving system. The improving method comprises steps of selecting a land, paving the moisture-separation layer, burying the salt-controlling and permeation-increasing closed conduits and water collection pipes, repairing the cofferdam, a trapezoidal soil pile, an inverted-trapezoidal trench, punching holes, applying soil fertilizer, planting crops, managing the field, and managing the salt-controlling and permeation-increasing closed conduits and the water collection pipes. Soil moisture storage property can be improved and nutrient can be remained; soil shatter value can be improved and soil hardening degree can be enhanced; water and fertilizer can be remained; great temperature increasing effect can be achieved; salt in a ploughing area can be greatly decreased; and salt content can be controlled within 0.2%.

Description

technical field [0001] The invention relates to a system and method for comprehensive improvement of cultivated land, in particular to a system and method for comprehensive improvement of saline-alkali land, belonging to the technical field of soil improvement for saline-alkali land. Background technique [0002] China currently has 100 million hectares of saline-alkali land, most of which are distributed in arid and semi-arid regions such as North China, Northwest and Northeast China, mainly including Xinjiang, Qinghai, Gansu, Ningxia, Shaanxi, Inner Mongolia, and northeast Shanxi. Most of them belong to the Yellow River system, and the groundwater level is significantly affected by the Yellow River system. The groundwater level is high. The local drinking wells are generally around 20m, and the groundwater level is around 2m. The main soil types are saline soil and aeolian sand, which are developed on the parent material of aeolian sand. The juvenile soil contains a lot of...
