Embodiment Construction

[0025] A method for extracting moderately salinized Suaeda salsa low-sodium high-amino acid plant salt, comprising the following steps:

[0026] 1. Planting of Suaeda salsa

[0027] 1) Selection of saline-alkali land

[0028] Select moderately salinized soil plots with a salt content of 1.0-1.4% and a pH of 7.6-7.8 in the 0-30cm soil layer.

[0029] 2) Tidy up the land

[0030] Before sowing, carry out plow and harrow operation to make the surface soil flat and finely crushed, and remove weeds. Each furrow is 3 meters wide, and the furrow should be flat. It is advisable to drain the water.

[0031] 3) Seed treatment

[0032] Preparation of root powder, soaking seeds

[0033] 0.05-0.1 parts of brassinolide, 0.5-1 parts of S-inducer, 5-7 parts of salicylic acid, 15-25 parts of biochemical fulvic acid.

[0034] Take 0.7g~1g of the above rooting powder and dissolve it with a small amount of alcohol, then add 1L of water, and soak the seeds for...

Abstract

The present invention provides an extraction method for low-sodium chloride and high-glutamic acid plant-salt from moderate salinization suaeda salsa, and includes suaeda salsa cultivation and plant-salt extraction; the plant-salt extraction comprises washing and subcritical liquid ammonia extracting. The suaeda salsa is high in emergence rate and transplanting survival rate; in mid-October, the suaeda salsa has a plant density of 500-510 plants/m2, an average biomass of 980-1100 g/m2 and a cover degree of 96-97%; the method can effectively improve saline-alkali soil of planting areas, reduce soil conductivity, and reduce soil salinity; the content of sodium chloride in the prepared plant-salt is 22.7-22.9% and the content of potassium chloride in the prepared plant-salt is 13.3-13.6% the prepared plant-salt has balanced nutrition indexes and significantly increased contents of aspartic acid, arginine, lysine, glutamic acid, glycine.

Description

technical field [0001] The invention relates to a method for extracting plant salt, in particular to a method for extracting medium-salinized Suaeda salsa low-sodium and high-amino acid plant salt, and belongs to the field of saline-alkali land transformation and comprehensive utilization. Background technique [0002] The prior art involves the artificial cultivation of salt-tolerant plants in saline-alkali land, but it is mainly used for agricultural utilization in saline-alkali environment, with the main purpose of harvesting vegetable oil and other products, which is effective for improving saline-alkali land, and the process of extracting plant salt is immature . Planting techniques such as soil preparation and sowing management adopted in the prior art have the following disadvantages: 1. The seeds are easily blown away by the wind, which affects the establishment of vegetation; affect seed growth. [0003] The method for extracting plant salt from Suaeda salsa in th...
