Problems solved by technology

Sea asparagus is one of the herbs with the highest salt content in the world, with a soluble salt content of about 37%. In addition, it is rich in vitamins, trace elements, minerals, fat and protein, and is very suitable for the production and development of plant salt. It has not attracted people's attention, and the preparation of plant salt from sea asparagus has not been industrialized
[0004] Especially in some medium and severe alkaline sulfate saline-alkali lands, the soil pH of saline-alkali lands is very high, the content of soil organic matter is insufficient, and the total nitrogen content is low. Limited by the soil conditions of saline-alkali lands, the survival rate of sea asparagus planted in the prior art is not high. The prepared The sodium chloride content of plant salt is low, the content of various nutritional indicators is low, and the content of potassium is high

Abstract

The invention discloses a method for extracting low-potassium plant salts from sea asparagus planted in sulfate saline-alkali soil with a medium-high alkalinity. The method is characterized by comprising the steps of planting sea asparagus in saline-alkali soil and extracting plant salts; wherein the planting comprises seed processing and seedling culture. The sea asparagus output for each mu is 3600 to 3650 kilogram, and the each 100 grams of sea asparagus contain 3.0 to 3.2 grams of amino acid. The plant salt yield is 1.93 to 1.96%; the sodium chloride content of the plant salts is 37.6 to 39.3%, the Ca content is 5460 to 5530 mg / kg, the VC content is 42.5 to 42.9 mg / g, the VE content is 85.1 to 86.5 mg / g, the valine content is 4.8 to 5.9 mg / g, the isoleucine content is 4.3 to 5.6 mg / g, and the potassium content is 2.3 to 3.4%.

Description

technical field [0001] The invention relates to a method for extracting plant salts, in particular to a method for extracting low-potassium plant salts from medium-severe alkaline sulfate saline-alkali ground sea asparagus, and belongs to the field of saline-alkali land transformation and comprehensive utilization. Background technique [0002] Sea asparagus, also known as salicornia, sea velvet, sea wormwood, rich cabbage, etc., is an annual herbaceous salt-accumulating plant, belonging to Chenopodiaceae, Salicornia genus, in the classification of halophytes, it belongs to the stem succulent euhalophyte . [0003] Sea asparagus in my country mainly grows in salt marshes, salt lakes and beaches in Liaoning, Hebei, Shanxi, Shaanxi, Ningxia, Gansu, Shandong, Jiangsu and other provinces. It has strong salt resistance and can be directly irrigated with seawater. It is a typical halophyte. Sea asparagus is one of the herbs with the highest salt content in the world, with a solub...
