System and method for improving salinized soil

Abstract

The invention discloses a salinized soil improvement system and method, belonging to the technical field of salinized soil improvement, which includes a planting part, the planting part is a strip-shaped soil mound arranged in an array, the top of the planting part is a planting platform, and the planting platform There are planting grooves on the top, and there are water seepage blind pipes with cutouts on the top for planting at the planting grooves. There are slopes on both sides of the planting platform, and both the slopes and the planting platform are covered with water-retaining films by film-covering trolleys at the same time; The irrigation device includes deep ditches opened between various planting parts. The water outlets of each deep ditch are connected to the water outlet pipe, and the water outlet pipe is respectively connected to the water storage tank and the filter tank through the water inlet pipe of the reservoir and the water inlet pipe of the filter tank. There are multi-layer clapboard filtering devices arranged in the filter tank. Both the reservoir and the filter tank are connected to the mixing tank through the water inlet pipe of the mixing tank. The mixing tank is connected to the irrigation water pipe. The irrigation water pipe is arranged on the planting groove and passes through the irrigation water. Dropper for drip irrigation.

Description

technical field [0001] The invention relates to the technical field of salinized soil improvement, in particular to a salinized soil improvement system and method. Background technique [0002] Soil salinization, also known as salinization, refers to the process in which the salt in the bottom soil or groundwater rises to the surface with capillary water, and after the water evaporates, the salt accumulates in the surface soil. Saline soil has the characteristics of high salinity and high alkalinity. The salt content in the soil is above 0.1%-0.2%, or the soil colloid absorbs a certain amount of exchangeable sodium, and the alkalization degree is above 15%-20%. Organic matter is destroyed and leached, trace elements are deficient, soil structure is poor, ventilation and water permeability are poor. It is manifested as white saline-alkali deposits on the soil surface. Severe salinized soil will cause plant wilting, poisoning and root rot death, making it difficult for plants...

AI Technical Summary

Problems solved by technology

It is manifested by white saline-alkali deposits on the soil surface. Severe salinized soil will cause plant wilting, poisoning and root rot death, making it difficult for plants to absorb fertilizer nutrients, affecting yield and causing economic losses.
