Embodiment 1

[0032] A method for planting Suaeda salsa in medium-low manganese saline-alkali land and extracting plant salt, comprising the following steps:

[0033] Step 1. Selection of saline-alkali land

[0034] In coastal saline-alkali land, the pH value of the 0-5cm soil layer is 8.6-9.0, the degree of alkalization is 21-22%, the total salt content is 3.02-3.45%, and the manganese content is 400-450mg / kg.

[0035] Step 2. Soil Treatment

[0036] a. Improve the soil. In the year before the planting of Suaeda salsa, in spring, evenly sprinkle 180kg / mu of soil amendment on the selected plots, plow 0.4m deep, rake level, and water once.

[0037] The soil conditioner includes the following components in parts by weight: 19 parts of fulvic acid, 13 parts of biochar, 8 parts of desulfurized gypsum, 22 parts of diatomaceous earth, 16 parts of water-retaining agent, 9 parts of ferric citrate, and 10 parts of bean curd residue , 8 parts of eggshell powder.

[0038] b. Fertilization. With...

Abstract

The invention provides a method for planting suaeda salsa and extracting plant salt in low and medium manganese saline-alkali soil. The method includes the steps of selecting saline-alkali soil, processing soil, planting suaeda salsa and extracting plant salt. The step of processing soil includes the substep of planting pokeberry roots and leersia hexandra in an interplanting mode according to the interplanting proportion of 6 to 4 and the planting density of 45 cm *45 cm. The manganese content of plant salt prepared through the method is 1.2-2.0 mg / Kg; the problem that the manganese content in plant salt extracted from suaeda salsa planted in low and medium manganese saline-alkali soil is too high is solved.

Description

technical field [0001] The invention relates to a method for extracting Suaeda saline salsa plant salt, in particular to a method for planting Suaeda salsa salsa in medium-low manganese saline-alkali land and extracting plant salt, which belongs to the field of saline-alkali land transformation and comprehensive utilization. Background technique [0002] The biological activity of plant salt depends on the selection and combination of raw plant species and the amount of inorganic salt they contain, the content and ratio of elements, and the biologically active components related to plants; People with a sodium diet, and people with metabolic disorders, functional decline and functional impairment due to imbalance or lack of trace elements in the body. Vegetable salt is different from biological salt. Plant salt belongs to the category of nutrition, while biological salt belongs to the category of marine ecology. The concept of biological salt was clearly put forward on pag...
