Abstract

The invention provides a method for extracting low-sodium plant salt contained in low-nitrite sea asparagus in a saline land. The method comprises the steps of planting the sea asparagus in the saline land and extracting the plant salt, wherein the step of planting the sea asparagus in the saline land include seed processing and seedling raising, and the plant salt extracting step include subcritical carbon dioxide-liquid ammonia extraction. By adopting the method for extracting the low-sodium plant salt contained in the low-nitrite sea asparagus in the saline land, the planting yield is 3650-3700 kilograms/mu, and the carbon sequestration capacity of absorbing carbon dioxide of plants per hectare is 5.3-5.5 tons. The nitrite content contained in plant bodies is remarkably reduced, and the yield of the obtained plant salt is improved. The sodium chloride content of the obtained plant salt is 38.1-38.9%, and the obtained plant salt is rich of amino acid, proline, phenylalanine and tyrosine.

Description

technical field [0001] The invention relates to a method for extracting plant salt, in particular to a method for extracting low-sodium plant salt in low-nitrite sea asparagus in saline-alkali land, and belongs to the field of saline-alkali land transformation and comprehensive utilization. Background technique [0002] Soil salinization and secondary salinization are one of the main problems of soil degradation in the world today. The area of ​​saline-alkali land in the world is about 955 million hm 2 , the area of ​​saline-alkali soil in my country is about 9.91×107hm 2 , of which the total area of ​​coastal tidal flats is about 2.35 million hm 2 . At present, my country's water and soil resources can only guarantee 500 million tons of grain production capacity, which is far from meeting the huge demand of the growing population. At the same time, my country's energy shortage contradiction is becoming increasingly acute, and the development of biomass energy must ensure...
