[0002] Sugarcane is an important economic crop, and its growth requires sufficient nutrients. Traditional fertilizer application methods have problems such as low fertilizer efficiency, fertilizer waste, and environmental pollution. Sugarcane has a long growth cycle, requires a large amount of fertilizer, and requires many types of fertilizers. When fertilizing sugarcane, if you only focus on the application of a single fertilizer, excessive application of a single fertilizer, unreasonable ratio of nitrogen, phosphorus, and potassium, lack of trace element fertilizers and organic matter, etc., it will cause soil compaction, yellow leaves, small leaves, slow growth, small stems, light weight, poor disease resistance, and prone to various diseases and pests. In the end, the yield of sugarcane is low and the sugar content is low. At the same time, after the fertilizer is applied, especially in the rainy areas in the south, the soluble inorganic fertilizer will dissolve more quickly, which will reduce the effect of fertilizer application and cause fertilizer waste, and also pollute the surrounding water bodies.

At the same time, fertilizers with different ratios can also be selected according to the actual conditions of the planting soil, so that the special fertilizer for sugarcane perfectly matches the growth needs of sugarcane. Example

[0039] On the basis of the above embodiments, an embodiment of the present invention provides a special fertilizer for sugarcane based on urea slow-release agent. On the basis of the above embodiments, the fertilizer also includes a preservative and a moisturizer, wherein the preservative is one or more of sodium benzoate, potassium sorbate, sodium p-hydroxybenzoate, and methyl p-hydroxybenzoate, and the moisturizer is one or more of polyvinyl alcohol, polyvinyl alcohol-polyvinyl acid copolymer, polyvinyl alcohol-polyacrylic acid copolymer, and polyvinyl alcohol-polyacrylate copolymer.

[0040] By using appropriate amounts of preservatives and moisturizers, the shelf life of the special fertilizer for sugarcane is increased, thereby improving the practical value of the special fertilizer for sugarcane. Example

[0041] On the basis of the above embodiments, the embodiment of the present invention provides a method for preparing a sugarcane-specific fertilizer based on a urea slow-release agent, comprising the following steps: Step 1: Evenly mix the slow-release urea, organic fertilizer, potassium sulfate, potassium dihydrogen phosphate, potassium nitrate, potassium chloride, trace elements and growth regulators according to the formula ratio, and avoid static electricity during the mixing process; Step 2: Mix the mixed fertilizer with an appropriate amount of water and stir evenly; Step 3: Put the mixed fertilizer into the fertilizer packaging bag and seal it for storage.

[0042] In the first step, when mixing fertilizers, it is important to weigh each fertilizer accurately according to the formula ratio and mix them thoroughly to ensure a balanced distribution of various nutrients in the fertilizer. In addition, static electricity should be avoided during the mixing process to avoid affecting the quality of the fertilizer.

[0043] In the second step, when mixing fertilizer and water, you need to pay attention to adding water in appropriate amounts according to the moisture and stability of the fertilizer to ensure that the moisture of the fertilizer is appropriate and will not be affected by being too dry or too wet. In addition, the mixture should be stirred thoroughly to ensure the uniform distribution of various nutrients in the fertilizer.

[0044] In the third step, when putting the mixed fertilizer into the fertilizer packaging bag, you need to pay attention to choosing a reliable quality packaging bag and sealing it to prevent the fertilizer from getting damp, deteriorating or volatilizing. In addition, the fertilizer ingredients, purpose, production date and other information should be marked on the packaging bag to facilitate users to understand the fertilizer.

[0045] Addition of trace elements: Trace elements can be added to fertilizers in the form of compounds or salts, such as ferrous sulfate, manganese sulfate, zinc sulfate, boric acid, molybdic acid, etc. When mixing fertilizers, the trace elements should be evenly mixed in the fertilizer to ensure a balanced distribution of the trace elements.

[0046] Addition of growth regulators: Growth regulators can be added to fertilizers in the form of powder or liquid, such as gibberellins, rooting powder, auxins, ethylene, etc. When mixing fertilizers, the growth regulators should be evenly mixed in the fertilizer to ensure balanced distribution of the growth regulators.

[0047] It should be noted that the amount of trace elements and growth regulators added should be appropriately controlled according to the growth stage of sugarcane and soil conditions to avoid excessive additions that have a negative impact on the growth of sugarcane. At the same time, when adding trace elements and growth regulators, reliable products should be selected, and appropriate quality control and testing should be carried out to ensure the quality and stability of the products.

[0048] Preservatives and moisturizers can also be added during the preparation process to extend the shelf life of the fertilizer.

[0049] The water needs to be filtered or disinfected before mixing to avoid the impact of impurities and microorganisms in the water on the fertilizer.

[0050] When preparing special fertilizer for sugarcane, water treatment also has a certain impact on the quality and stability of the fertilizer. An appropriate amount of water should be added according to the humidity and stability of the fertilizer to ensure that the humidity of the fertilizer is appropriate and the quality of the fertilizer will not be affected by being too dry or too wet.

[0051] If tap water is used, it should be filtered first to remove impurities and microorganisms in the water. You can use a filter or other filtering equipment for treatment; in order to avoid the impact of microorganisms in the water on fertilizers, you can also use disinfectants to disinfect the water. Commonly used disinfectants include bleaching powder, hydrogen peroxide, etc.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
