Embodiment 1

[0027] A method for extracting plant salt in sea asparagus with high carbon fixation capacity in saline-alkali soil, comprising the following steps:

[0028] 1. Cultivation of asparagus in saline-alkali land

[0029] (1) Selection of saline-alkali land

[0030] Saline soil silt silt clay, below 60cm is mainly composed of fine clay particles of silt formed by marine sediments, the soil is mainly composed of sodium chloride salt, and the thickness of the cultivated layer is generally about 30cm, with high salt content In 4.0% heavy saline soil.

[0031] (2) Arranging the land

[0032] Use mechanical plowing to plow the surface soil, rake the soil block to loosen the surface soil, and make the surface flat without obvious ups and downs; furrows are opened, each furrow is 2-3m wide, the furrow surface is flat, and the middle 1m is 15cm deep, and the middle The deep ditch is used as a benchmark, and the ditch is 7 cm deep at intervals of 30 cm on both sides.

Abstract

A method for extracting plant salt contained in sea asparagus having high carbon sequestration capacity in a saline land comprises the steps of planting the sea asparagus in the saline land and extracting the plant salt, wherein the plant salt extracting step include cleaning, drying, smashing and subcritical propane-liquid ammonia extraction. By adopting the method for extracting the plant salt contained in the sea asparagus having high carbon sequestration capacity in the saline land, saline-alkali land soil in a planting area is effectively improved, the soil salinity is reduced, soil organic matter is increased by 1.3-1.46g/kg, the water seepage speed of the soil is improved by 47-55%, and the soil salinity is 2.0-2.5%. The yield of obtained plant salt is 1.96-2.0%, the sodium chloride content of the plant salt is 37.2-38.9%, the content of trace elements and amino acid is remarkably improved, the glutamic acid is 12.3-12.6 mg/g, the glycine is 5.8-6.9 mg/g, alanine 6.5-7.5g/g, and the carbon sequestration capacity of absorbing carbon dioxide of the sea asparagus per hectare is 5.3-5.4 tons.

Description

technical field [0001] The invention relates to a method for extracting plant salt, in particular to a method for extracting plant salt in sea asparagus with high carbon fixation capacity in saline-alkali land, and belongs to the field of saline-alkali land transformation and comprehensive utilization. Background technique [0002] Sea asparagus, in addition to being rich in amino acids, proteins, vitamins, and minerals, also contains natural plant salts and natural saponins, which can effectively reduce cholesterol on the blood vessel wall, and play a role in lowering blood pressure, lowering fat, losing weight, Promote the metabolism of the liver. These unique nutrients make sea asparagus a new variety of seawater vegetables in my country, which is very suitable for processing into various deep-processed products. [0003] However, so far, the emergence rate of sea asparagus and the survival rate after transplanting and planting are not high, and the ability of sea aspara...
