Embodiment 1

[0022] An ecological slow-release fertilizer resistant to root rot, prepared from the following raw materials in parts by weight: 20 parts of nitrogen fertilizer, 10 parts of phosphate fertilizer, 8 parts of potassium fertilizer, 10 parts of humic acid, 3 parts of medium and trace elements, and 3 parts of attapulgite , 3 parts of borax, 1 part of calcium sulfate, 2 parts of lime powder, 0.8 part of calcium chloride, 0.1 part of cotton wool, 5 parts of coating agent; After stirring for 1 hour in hot water at 80°C, add 2% acetic acid solution to form a 5% cornstarch solution, stir for 40 minutes, and mix KH560, which accounts for 5% of the starch mass, and 1% of the starch mass. The lignin was dissolved in 2 mL of ethanol, then added to the starch acetic acid solution, continued to stir, and kept at a temperature of 60°C for 4 hours. After the reaction was completed, the solution was distilled off the solvent under reduced pressure to obtain a solid, which was then dried in vacuo...

Embodiment 2

[0031] An ecological slow-release fertilizer resistant to root rot, which is prepared from the following raw materials in parts by weight: 25 parts of nitrogen fertilizer, 13 parts of phosphate fertilizer, 9 parts of potassium fertilizer, 15 parts of humic acid, 7 parts of medium and trace elements, and 4 parts of attapulgite , 4 parts of borax, 2 parts of calcium sulfate, 3 parts of lime powder, 1.5 parts of calcium chloride, 0.3 part of cotton wool, 8 parts of coating agent; After stirring for 1 hour in hot water at 80°C, add 2% acetic acid solution to form a 5% cornstarch solution, stir for 40 minutes, and mix KH560, which accounts for 5% of the starch mass, and 1% of the starch mass. The lignin was dissolved in 2.5 mL of ethanol, then added to the starch acetic acid solution, continued to stir, and kept at a temperature of 60°C for 4.5 hours. After the reaction was completed, the solution was distilled off the solvent under reduced pressure to obtain a solid, which was then...

Embodiment 3

[0040] An ecological slow-release fertilizer resistant to root rot, which is prepared from the following raw materials in parts by weight: 30 parts of nitrogen fertilizer, 16 parts of phosphate fertilizer, 10 parts of potassium fertilizer, 20 parts of humic acid, 10 parts of medium and trace elements, and 5 parts of attapulgite , 5 parts of borax, 3 parts of calcium sulfate, 4 parts of lime powder, 2.5 parts of calcium chloride, 0.5 part of cotton wool, 10 parts of coating agent; After stirring for 1 hour in hot water at 80°C, add 2% acetic acid solution to form a 5% cornstarch solution, stir for 40 minutes, and mix KH560, which accounts for 5% of the starch mass, and 1% of the starch mass. The lignin was dissolved in 3mL of ethanol, then added to the starch acetic acid solution, continued to stir, and kept at a temperature of 60°C for 5 hours. After the reaction was completed, the solution was evaporated to remove the solvent under reduced pressure to obtain a solid, which was...

Abstract

The invention discloses an ecological anti-root-rot slow-release fertilizer and a preparation method thereof, and belongs to the technical field of fertilizers. The fertilizer is prepared from, by weight, 20-30 parts of a nitrogen fertilizer, 10-16 parts of a phosphorus fertilizer, 8-10 parts of a potassium fertilizer, 10-20 parts of humic acid, 3-10 parts of medium and trace elements, 3-5 parts of attapulgite, 3-5 parts of borax, 1-3 parts of calcium sulfate, 2-4 parts of lime powder, 0.8-2.5 parts of calcium chloride, 0.1-0.5 part of dazomet and 5-10 parts of a film coating agent. The film coating agent is obtained by modifying corn starch. The fertilizer is scientific in formula and remarkable in fertilizer effect, and can effectively reduce the occurrence probability of root rot of crops, and improve the disease resistance of the crops. At the same time, the fertilizer has a good slow release effect, continuously provides stable nutrients for the crops for a long time, improves thecrop yield and the crop quality, has no pollution to creatures, soil and water sources, maintains the ecological environment of soil, and is safe and environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of fertilizers, and in particular relates to a root rot resistant ecological slow-release fertilizer and a preparation method thereof. Background technique [0002] The application of slow and controlled release fertilizers can improve the utilization rate of fertilizers, which is the direction of fertilizer development in the 21st century. In a broad sense, slow and controlled release fertilizers refer to fertilizers that release nutrients at a slow rate and have a long release period, and can meet the growth needs of crops during the entire growth period of crops. But in a narrow sense, there are different definitions for slow-release fertilizers and controlled-release fertilizers. Slow-release fertilizers (SRFs), also known as long-acting fertilizers, mainly refer to fertilizers that are converted into effective plant nutrients at a slower rate than ordinary fertilizers after being applied to the soil. ...
