preparation example Construction

[0024] See figure 1 , the present invention provides a kind of preparation method of composite calcium-silicon organic fertilizer, comprising: mixing and stirring calcium-rich material, manure, and water evenly to form a Ca-organic mixture; collecting ammonia; cultivating the Ca-organic mixture for a period of time and The silicon-rich substances are mixed to obtain a Ca-Si organic mixture; the Ca-Si organic mixture is mixed with mineral acid and kept for a period of time; dried and cultivated; and granulated to obtain the composite calcium-silicon organic fertilizer.

[0025] Specifically, the calcium-rich substance is mixed with animal or / and poultry manure for 10 minutes to 1 hour, and the water content of the original mixture is 40-60%; the ammonia is captured with water from the beginning of the mixing process, and lasts for 5-10 hours; The Ca-organic mixture was incubated for 10-100 hours following the stirring process; ammonia gas was collected from the mixed gas. Mix ...

Embodiment 1

[0041] Take quicklime, poultry manure and mix for 10 minutes to ensure that the water content of the original mixture is 40%; capture ammonia with water from the beginning of the mixing process and continue for 5 hours; maintain the Ca-organic mixture for 10 hours after the mixing process; in 10 minutes Mix the Ca-organic mixture with a liquid silicon-containing solution with a Si content of 10 mg / liter to obtain a Ca-Si-organic mixture; mix the resulting Ca-Si-organic mixture with phosphoric acid for 1 to 60 minutes, and then keep it for 1 ~ 10 days, drying the culture mixture until the moisture content is 1%, and granulating to obtain a compound calcium-silicon organic fertilizer. Wherein the mass ratio of calcium-rich substance to poultry manure is 1:3, and the volume ratio of the Ca-Si organic mixture to phosphoric acid is 1:100.

Embodiment 2

[0043] Mix calcium-rich substances and animal manure for 1 hour, and ensure that the water content of the original mixture is 60%; maintain the Ca-organic mixture for 100 hours after the stirring process, and capture ammonia with water at the same time, and continue for 10 hours; Mix the Ca-organic mixture with a liquid silicon-containing solution with a Si content of 50,000 mg / L within 1 hour to obtain a Ca-Si-organic mixture; mix the resulting Ca-Si-organic mixture with nitric acid for 1 to 60 minutes, and then keep 1 to 10 days, drying the culture mixture until the water content is 1%; granulating to obtain the compound calcium-silicon organic fertilizer. Wherein the mass ratio of calcium-rich substance to animal feces is 1:3, and the volume ratio of the Ca-Si organic mixture to nitric acid is 10:1.

Abstract

The invention belongs to the technical field of soil improvement, and particularly relates to a composite calcium-silicon organic fertilizer, a raw material formula and a preparation method. The preparation method of the composite calcium-silicon organic fertilizer comprises the following steps: uniformly mixing and stirring calcium-rich substances, manure and water to form a Ca-organic mixture; collecting ammonia gas; culturing the Ca-organic mixture for a period of time and then mixing the Ca-organic mixture with a silicon-rich substance to obtain a Ca-Si organic mixture; mixing the Ca-Si organic mixture with mineral acid, and keeping for a period of time; drying and culturing; and granulating to obtain the composite calcium-silicon organic fertilizer.

Description

technical field [0001] The invention belongs to the technical field of soil improvement, and in particular relates to a compound calcium-silicon organic fertilizer, a raw material formula and a preparation method. Background technique [0002] It is very important to improve the soil fertility of cultivated land. The intensification of agriculture, including the high use of traditional mineral fertilizers, has a negative impact on soil fertility and reduces farmers' profitability and crop quality. Application of mineral acids leads to lower pH, increased mobility of heavy metals, and increased greenhouse gas emissions. However, nitrogen is a vital macronutrient for cultivated plants, and reducing the application of mineral acids can negatively affect the yield of cultivated plants. Soil fertility is an important factor for sustainable agriculture. Today, many cultivated soils are degraded and need to be restored to their fertility levels. However, there is currently no g...
