A kind of silicon element alkaline fertilizer for improving soil acidification and preparation method thereof

Abstract

The invention provides a silicon-element alkaline fertilizer for improving soil acidification and a preparation method of the silicon-element alkaline fertilizer. The silicon-element alkaline fertilizer comprises the following raw materials in parts by weight: 15-20 parts of potassium silicate, 20-25 parts of potassium humate, 15-20 parts of urea, 0.1-0.5 part of ammonium molybdate, 0.2-2 parts of ethylenediamine tetraacetic acid, 0.1-0.5 part of part of hexanoic,2-(diethylamino) ethyl estercitrate, 0.1-0.5 part of compound sodium nitrophenolate, 12-15 parts of powdered rock phosphate, 6-7 parts of calcium chloride, 5-7 parts of a natural potassium magnesium fertilizer and 18-20 parts of matured compost. By virtue of the silicon-element alkaline fertilizer, the acidified soil can be effectively improved; the pH of the soil is 6.8-7.0 after the silicon-element alkaline fertilizer is used for a year; the specific gravity of the soil is 2.63-2.64g / cm<3>; the volume-weight of the soil is 1.12-1.13g / cm<3>; and the total porosity of the soil is 57%-58%.

Description

technical field [0001] The invention relates to a fertilizer and a preparation method thereof. Specifically, it relates to a silicon element alkaline fertilizer for improving soil acidification and a preparation method thereof, belonging to the field of agricultural technology. Background technique [0002] There is a large area of ​​acidic soil in our country. The main problem of acidic soil is low nutrient availability, and there are many types of nutrients involved. For example, many acidic soils are generally deficient in nitrogen, phosphorus, and potassium; many soils are deficient in calcium and magnesium; and most acidic soils are severely deficient in phosphorus. [0003] Patent CN201010580872.1 discloses a glass-based slow-release compound fertilizer and its preparation method. The formula and mass ratio of the compound fertilizer are: 10-30 parts of waste glass, 40-60 parts of calcium carbide, and 1-30 parts of phosphate fertilizer 0-30 parts of potassium fertili...

AI Technical Summary

Problems solved by technology

[0006] Although the above patents provide some solutions for improving soil acidification, the following defects still exist: 1. Although the pH is improved, the effects of improving soil specific gravity, soil bulk density and total soil porosity are not significant

2. It is difficult to control the intensity of pH adjustment, and it is easy to burn seedlings if the control is not good

3. Cannot effectively improve the lack of multiple nutrients at the same time

4. The existing acidified soil improvement products did not improve the symptoms of silicon deficiency in crops
