Sandy saline and alkaline land soil remediation device and remediation method thereof

Abstract

The invention discloses a sandy saline and alkaline land soil remediation device. The sandy saline and alkaline land soil remediation device comprises a water storage sponge, a bottom plate, a water suction sponge, a shell and a top plate. A separation plate is arranged at the top end in the shell, and a plurality of mounting holes are evenly formed in the separation plate and the bottom of the shell at equal intervals. According to the sandy saline and alkaline land soil remediation device, the water suction sponge is arranged at the position, between an upper pressing plate and a lower pressing plate, in the shell, the water storage sponge is arranged at the position, above the separation plate in the shell, plants are planted on soil above the shell, the water suction sponge can be utilized for absorbing and draining underground water on the deep layer of the soil, it is avoided that underground water where salt is dissolved rises to the surface of the soil through the capillary action to evaporate to form saline and alkaline land, rainwater permeating into the shell can be collected, the interior of the shell and a drainage can be collected, and the service life of the device is prolonged. The wettability of the soil is improved through the water storage sponge arranged above the separation plate, growth of the planting is convenient, the soil on the upper layer is managedand remediated, and therefore the effect and efficiency of saline and alkaline land management are improved.

Description

technical field [0001] The invention relates to the technical field of soil restoration, in particular to a sandy saline-alkali soil restoration device and a restoration method thereof. Background technique [0002] Saline-alkali land is a type of salt accumulation, which means that the salt contained in the soil affects the normal growth of crops. According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954.38 million hectares, of which my country is the largest 99.13 million hectares, the formation of alkaline soil and alkalized soil in my country is mostly related to the accumulation of carbonate in the soil, so the degree of alkalization is generally high, and plants in severe saline-alkali soil areas can hardly survive. [0003] All kinds of saline-alkali soils are formed under certain natural conditions. The essence of their formation is mainly the redistribution of various soluble salts in the horizontal and vertical di...

Problems solved by technology

[0005] The purpose of the present invention is to provide a sandy saline-alkali soil repair device and its repair method, to solve the problem that the existing saline-alkali land proposed in the above background technology has no efficient treatment method, and can only be carried out by traditional soil overturning and repeated planting preparation. Saline-alkali is suppressed, but the work efficiency is low and the treatment effect is relatively poor. The manpower and material resources are invested heavily, and the treatment effect is not obvious.
