Embodiment 1

[0025] 1. Raw materials

[0026] Jujube charcoal 18 kg, vinegar grains powder 27 kg, attapulgite 6 kg, humic acid 8 kg, superphosphate 6 kg, polyacrylamide PAM (anionic, average molecular weight about 12 million) 2 kg, EM bacteria 0.5 kg .

[0027] 2. Saline-alkali soil improver 1#

[0028] Calcining attapulgite at 400°C for 1 hour, cooling to room temperature, grinding, and passing through a 100-mesh sieve to obtain modified attapulgite;

[0029] Mix jujube seed charcoal, vinegar grains powder, humic acid, superphosphate, PAM, EM bacteria and modified attapulgite, stir well, then grind and pass through a 100-mesh sieve to obtain saline-alkaline soil improver 1#.

Embodiment 2

[0031] Refer to Example 1 to prepare saline-alkali soil improver 2#, the difference lies in the amount of raw materials, specifically: 15 kg of jujube stone charcoal, 25 kg of vinegar grain powder, 8 kg of attapulgite, 7 kg of humic acid, 8 kg of superphosphate, polypropylene Amide PAM (anionic type, average molecular weight about 12 million) 3 kg, EM bacteria 0.6 kg.

Abstract

The invention discloses a saline-alkali soil improver which is prepared from the following raw materials in parts by weight: 10 to 25 parts of jujube pit carbon, 15 to 40 parts of vinegar residue powder, 3 to 10 parts of attapulgite, 5 to 10 parts of humic acid, 5 to 10 parts of calcium superphosphate, 1 to 5 parts of a water-retaining agent and 0.1 to 4 parts of a microbial agent. The soil improver can significantly improve the physicochemical properties of saline-alkali soil, reduce the pH value and total salt content of soil, increase the organic matter content of the soil, increase the granular structure of the soil and improve the water and fertilizer retention capacity of the soil; in addition, the soil improver is especially suitable for watermelon saline-alkali soil, and can greatly increase the yield of watermelons.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a saline-alkali soil improver and its application. The improver is especially suitable for the improvement of saline-alkali soil for planting watermelon. Background technique [0002] Among all saline-alkali land improvement technologies, chemical improvement has the advantages of low cost, quick effect, and flexible and adjustable formula. It does not depend on fresh water resources and supporting engineering facilities, and is less affected by climate. Regions with large variations are widely used. [0003] After decades of research, a large number of patented technologies for chemical improvement of saline-alkali land have emerged, and the types of raw materials suitable for improvement of saline-alkali land are gradually becoming familiar to those skilled in the art. However, practical application shows that there are not many products that can really ...
