Abstract

The invention provides a method for extracting low-cuprum low-arsenic plant salt contained in 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 land preparation, seed processing and seedling raising, and the plant salt extracting step include smashing, microwave wall breakage and ultrasonic-assisted subcritical propane-liquid ammonia extraction. By adopting the method, the saline-alkali land soil in a planting area is effectively improved, the soil electric conductivity is reduced, the water seepage speed of the soil is improved, the soil humus is increased by 1.5-1.6g / kg, and the heavy metal copper and arsenic content of the obtained plant salt is remarkably reduced.

Description

Technical field [0001] The present invention involves a method of extraction of plant salt, which specifically involves the extraction method of low copper and low arsenic plant salt in a saline -alkali land. It belongs to the reconstruction of saline -alkali land and comprehensive utilization. Background technique [0002] Sea asparagus is a real salt plant. Its stems and leaves are already meaty, and the plant tissue liquid soaked is large. It contains a large amount of water. It forms a high osmotic pressure with the outside world. It can absorb a large amount of salt from the soil.In liquid foam, a natural plant salt is formed in the plant body, and certain soil salt can stimulate its growth. Therefore, sea asparagus is suitable for excellent economic crops grown in saline -alkali land. [0003] However, under natural conditions, the nutrient content in salt -related soil is generally low, and it is difficult to meet the needs of plant growth and development. The natural grow...
