Embodiment 1

[0024] 1. Raw materials

[0025] Rice husk charcoal 20 kg, vinegar residue powder 32 kg, attapulgite 8 kg, fulvic acid 7 kg, superphosphate 7 kg, EM bacteria 0.5 kg.

[0026] 2. Saline-alkali soil improver 1#

[0027] Calcining attapulgite at 400°C for 1 hour, cooling to room temperature, grinding, and passing through a 100-mesh sieve to obtain modified attapulgite;

[0028] Mix rice husk charcoal, vinegar grains powder, fulvic acid, superphosphate, EM bacteria and modified attapulgite, stir well, then grind and pass through a 100-mesh sieve to obtain saline-alkali soil improver 1#.

Embodiment 2

[0030] Refer to Example 1 to prepare saline-alkali soil improver 2#, the difference lies in the amount of raw materials, specifically: rice husk charcoal 23 kg, vinegar grains powder 30 kg, attapulgite 6 kg, fulvic acid 9 kg, superphosphate 7 kg, EM Bacteria 0.8 kg.

Abstract

The invention discloses a saline-alkali land improving agent, which comprises the following raw materials in parts by weight: rice husk charcoal 15-30, vinegar grains powder 20-40, attapulgite 3-10, fulvic acid 5-10, superphosphate 5 ‑10, microbial agent 0.1‑4. The improver can significantly improve the physical and chemical properties of saline-alkali land, reduce soil pH and total salt content, increase soil organic matter content, increase soil aggregate structure, enhance air permeability and water and fertilizer retention capacity, and is especially suitable for cotton planting in saline-alkali land. Significantly increased cotton yield and quality.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a saline-alkali land improver and its application. The improver is especially suitable for the improvement of saline-alkali land for cotton planting. Background technique [0002] With the continuous growth of my country's total population, the area of ​​cultivated land per capita has decreased year by year, and improper measures such as excessive fertilization have led to more serious soil salinization, and the area of ​​saline-alkali land has increased year by year. In order to improve soil quality and yield per mu, technical means such as biological improvement, physical improvement, chemical improvement, and combined improvement have been used to improve saline-alkali land. Among them, chemical improvement is widely used due to its advantages of low cost, quick effect, and flexible and adjustable formula. application. [0003] After decades of research, ...
