preparation example Construction

[0020] The preparation method of saline-alkali soil conditioner, the operation steps are:

[0021] Select raw materials according to the following weight percentages: polymaleic acid 0.4-8; sodium dodecylbenzenesulfonate 1.1-25; polyaspartic acid 0.3-18; malic acid 0.3-5; oxalic acid 0.3-18; sulfuric acid Ammonium 0.1-1; Plant growth agent 0.3-2; Spreading agent 0.1-2; Toluene silicone oil 0.001-0.05; Water balance;

[0022] First add sodium dodecyl sulfonate to water at 5-30°C, stir to form foam, add a small amount of toluene silicone oil as a defoamer, and after the foam is completely eliminated, add malic acid, oxalic acid, spreading agent, ammonium sulfate, Stir for 5 minutes to allow it to fully dissolve, then add polyaspartic acid, auxin, and polymaleic acid, and stir for another 15-20 minutes to allow it to fully emulsify to form a polymer substance, and finally make up 100% with water parts by weight.

Abstract

The invention discloses a saline-alkali soil modifier, a preparation method and application thereof, and relates to a saline-alkali soil modifier, and a preparation method and application technology thereof. The saline-alkali soil modifier is prepared by dissolving the following raw materials, by weight: 0.4-8 parts of poly maleic acid, 1.1-25 parts of sodium dodecyl benzene sulfonate, 0.3-18 parts of polyaspartic acid, 0.3-5 parts of malic acid, 0.3-18 parts of oxalic acid, 0.1-1 part of ammonium sulfate, 0.3-2 parts of a plant growth agent, 0.1-2 parts of a spreader, 0.001-0.05 part of toluene silicone oil and the balance of water. The application method is as below: diluting the modifier, adding to a trickle irrigation, and dripping the modifier on the soil. The invention solves the problems of the existing technology for saline-alkali soil improvement, such as high engineering cost, unobvious improvement effect, incapability to durable application, and difficulty in large area promotion.

Description

technical field [0001] The present invention relates to a saline-alkali soil improver and its preparation method and application technology, in particular to a saline-alkali soil improver and a saline-alkali soil improver for providing nutrients to microorganisms in saline-alkali soil, and the preparation method and application of the saline-alkali soil improver . Background technique [0002] For a long time, extensive and in-depth research has been carried out on the improvement of saline-alkali land at home and abroad, but most of them focus on engineering measures and rarely apply biotechnology. Although some achievements have been made, there are still some insurmountable difficulties, such as high engineering costs, The improvement effect is not obvious, it cannot be used for a long time, and it is difficult to promote in a large area. The causes of saline-alkali soil in different regions are different, the soil nutrients are different, and the topography, landform, c...
