The invention discloses a preparing method of alkaline soil modifier, which comprises the following steps: dissolving polyacrylic acid in the water; adding inorganic acid, pyroligneous and plant hormone sequently; stirring to blend evenly. The modifier contains 5-25% polyacrylic acid, 10-50% inorganic acid, 1-5% pyroligneous, 0.01-2.0% plant hormone and water. The invention reduces soil pH value effectively, which is beneficial for plant growth.
Description
Technical field: [0001] The invention relates to a preparation method of a saline-alkali soil improver, that is, a preparation method of an improver capable of reducing soil pH, soluble salt content and water retention. Background technique: [0002] The threat of soil salinization to agriculture is a global problem, with about 1 billion hectares of 2 The saline-alkali land occupies nearly 25% of the land area. 20% of the world's arable land and nearly half of the irrigated land are threatened by varying degrees of salt damage. my country has only 100 million hm of arable land 2 , of which more than 20 million hm 2 For salt wasteland and 0.067 billion hm 2 It is a saline-alkali soil land, and it is one of the world's largest countries with saline-alkali land. my country is a large agricultural country, and agricultural development is one of the important components of national economic development. Studying effective measures to control saline-alkali land, transforming...
