Salinized soil improvement system and method

Abstract

The invention discloses a salinized soil improvement system and method, and belongs to the technical field of salinized soil improvement. The salinized soil improvement system comprises planting parts, the planting parts are long-strip-shaped soil piles arranged in an array, the tops of the planting parts are provided with planting platforms, and planting grooves are formed in the planting platforms; and water seepage blind pipes with notches formed at the tops for plant planting are arranged in the planting grooves, slopes are arranged at the two sides of each planting platform, and the slopes and the corresponding planting platform are covered with water retention covering films at the same time through a film covering trolley. An irrigation device comprises deep ditches formed between the planting parts, water outlets of the deep ditches communicate with a water outlet pipe, the water outlet pipe communicates with a reservoir and a filter tank through a reservoir water inlet pipe and a filter tank water inlet pipe correspondingly, and multiple layers of partition plate filter devices are arranged in the filter tank; and the reservoir and the filter tank are both communicated with a mixing box through a mixing box water inlet pipe, the mixing box is connected with an irrigation water pipe, and the irrigation water pipe is arranged on the planting grooves and conducts drip irrigation through irrigation droppers.

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.
