Problems solved by technology

In some existing patent documents, there are many sulfur-containing fertilizers or soil improvers, but the sulfur content is generally lower than 5-15%, and the particles are generally large, which is not conducive to the absorption and transformation of the soil. The main disadvantages are: Low sulfur content, poor absorption and transformation effect, large dosage, poor processing safety

example 1

[0015] Example 1: Processed into 3.8mm particles according to the above-mentioned preparation method, the mass percentages of its components are as follows:

[0016] Sulfur: 40%;

[0017] Urea: 52%;

[0018] Bentonite: 8%.

[0019] After a comparative test in the cotton fields of the 24th regiment of the Second Agricultural Division of Xinjiang, 100 kilograms of the sulfur-based soil improver of the present invention was used per mu, the pH value of the soil was reduced by 0.5-0.6, and the cotton yield was increased by 27.5%.

example 2

[0020] Example 2: Processed into 2.5mm particles according to the above-mentioned preparation method, the mass percentages of its components are as follows:

[0021] Sulfur: 75%;

[0022] Ammonium sulfate: 20%;

[0023] Gypsum: 5%.

[0024] Through the comparative test in the 24th regiment of the Second Agricultural Division of Xinjiang, using 150 kilograms of the sulfur-based soil improver of the present invention per mu, the pH value of the soil decreased by 0.6-0.8, and the yield of melon seeds increased by 31.2%.

example 3

[0025] Example 3: be processed into the particle of 4.5mm by above-mentioned preparation method, its each component mass percent is as follows:

[0026] Sulfur: 65%;

[0027] Ammonium bicarbonate: 25%;

[0028] Attapulgite: 10%.

[0029] Through the comparative test in the corn field of the 24th regiment of the Second Agricultural Division of Xinjiang: 50 kg of sulfur-based compound fertilizer of the present invention is used per mu, the pH value of the soil is reduced by 0.4-0.6, and the corn yield is increased by 16.8%.

Abstract

The invention relates to the technical field of agriculture and in particular relates to a sulfur-based soil conditioner. The sulfur-based soil conditioner disclosed by the invention is composed of the following components in percentage by mass: 35-90% of sulfur, 5-60% of general chemical fertilizers and 2-10% of adhesives. The sulfur-based soil conditioner disclosed by the invention has the advantages that the soil conditioner is high in sulfur content and small in usage, large in sulfur specific surface area and good in absorption and transformation effect, and the preparation method is simple, safe to process and convenient to use; and moreover, in sulfur-free saline-alkali soil, due to a contrast test of planting seeding-watermelon, cotton and corn, 50-150kg of the sulfur-based soil conditioner disclosed by the invention is used per mu, and the yield can be increased by 12-32%.

Description

technical field [0001] The invention relates to the technical field of agriculture, in particular to a sulfur-based soil conditioner. Background technique [0002] According to statistics, there are about 4 million hectares of sulfur-deficient high-PH saline-alkali land cultivated in my country, and sulfur-containing fertilizers or soil improvers used for sulfur-deficient high-PH saline-alkali land are rarely seen in the market. In some existing patent documents, there are many sulfur-containing fertilizers or soil improvers, but the sulfur content is generally lower than 5-15%, and the particles are generally large, which is not conducive to the absorption and transformation of the soil. The main disadvantages are: Low sulfur content, poor absorption and transformation effect, large dosage, poor processing safety. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a sulfur-based soil condit...
