Problems solved by technology

Although it can dilute the salinity in the surface layer of saline-alkali soil in a short period of time to achieve a certain improvement effect, but the workload is heavy and the cost is high, and as the irrigation water penetrates into the deep layer, the salt will continue to dissolve. When the surface is in a dry state, the saline-alkali solution will As the pores in the soil drain to the soil surface, they eventually form salt deposits, still detrimental to plant growth

Embodiment Construction

[0026] The power output of the power machine is used to drive the vacuum machine, and the negative pressure generated at the same time is transmitted to the vacuum suction cup, and acts on the sprayed or irrigated ground through the filter crawler. The huge negative pressure generated by the vacuum machine removes the saline-alkali solution from the soil layer. The extraction is separated out and collected into the collection tank. Under the constant speed traction of the tractor (or other power machinery), the fuselage is driven and the filter crawler is driven, so as to continuously extract the saline-alkali solution in the soil during the displacement process to achieve the purpose of removing the saline-alkali components in the soil.

[0027] Before operation, it must be fully sprayed or watered with water on the saline-alkali ground. Generally, the depth of water penetration is 20cm-30cm, and the humidity is 30%-40%. Soluble salts such as sodium sulfate, sodium carbonate,...

Abstract

The invention relates to a working principle of a vacuum filtration salt leaching machine on saline-alkali land and an application of the vacuum filtration salt leaching machine, and belongs to an innovative method for mechanically governing the saline-alkali land. A vacuum absorption principle is used, and a saline-alkali solution in soil is subjected to suction filtration and extraction, so that the saline-alkali content in the soil is reduced, and the alkalization degree is reduced. A tractor (or any other power machine) is used as a power source and movement traction to drive a vacuum machine in movement to perform suction filtration and extraction on the saline-alkali solution under a water-soluble state in the saline-alkali soil, and enriched saline-alkali solutions are discharged, so that the purpose of governing the saline-alkali land in a mechanical, automated and large-scale manner is achieved.

Description

technical field [0001] Mechanical methods to control saline soil and saline-alkali cultivated land. Background technique [0002] The area of ​​saline soil in the world is about 10 trillion hectares. The area of ​​saline soil in my country is 99.13 million hectares (excluding coastal beaches), and 7.6 million hectares of salinized and alkalized cultivated land, accounting for about one-fifth of the total cultivated land area . Most of the saline-alkali land is distributed in the arid and rainless northern regions of my country. Taking Xinjiang as an example, there are 1,333,300 hectares of arable land, nearly one-third of which have been salinized, and more than 80% of the soil has secondary salinization. In recent years, the popularization and application of drip irrigation technology in agricultural production has aggravated the salinization of cultivated land and increased the number of abandoned farmland. [0003] Sodium chloride is the main salt in coastal tidal flats...
