Embodiment 1

[0041] The fertilizer needed for each sugarcane is as follows: nitrogen 8g per tree, phosphorus pentoxide 2.86g per tree, potassium chloride 8.57g per tree, urease inhibitor 0.2-0.5g per tree. 3,500 sugarcane trees are planted per mu, and the fertilization conditions per mu are as follows: nitrogen 28kg per mu, phosphorus pentoxide 10kg per mu, potassium chloride 30kg per mu.

[0042] According to the fertilizer situation required by each sugarcane, determine the ratio of each component contained in a fertilizer granule: nitrogen 7-8g, phosphorus pentoxide 2-3g, potassium chloride 8-9g, urease inhibitor 0.2 -0.5g. Fertilizer raw materials are prepared into powder, and then granulated by a granulator. Specifically, take each component of the fertilizer raw material, mix the components of the fertilizer raw material, add water and carrageenan, mix and stir to obtain a mixed preparation; put the mixed preparation into a granulator for high-temperature drying, and the drying temp...

Abstract

The invention discloses a special fertilizer for a primary root zone of sugarcane and a preparation process of the fertilizer. The process comprises the following steps: preparing fertilizer granules from fertilizer raw materials, wherein the fertilizer comprises the following raw materials: a nitrogen fertilizer, phosphorus pentoxide, potassium chloride and a urease inhibitor, and according to the amount of the fertilizer required by one sugarcane for an annual long term, the prepared fertilizer granule comprises the following components: 7-8 g of the nitrogen fertilizer, 2-3 g of the phosphorus pentoxide, 8-9 g of the potassium chloride and 0.2-0.5 g of the urease inhibitor; preparing a coating solution by using polyethylene resin; and spraying the coating solution to the surfaces of the fertilizer particles, so as to form a polyethylene film layer on the surfaces of the fertilizer particles, wherein the polyethylene film layer is a shell completely wrapping the fertilizer particles. The prepared fertilizer releases fertilizer nutrients to crops according to the growth needs of sugarcane, and one fertilizer can meet one growth cycle of each sugarcane plant, namely the fertilizer demand of the crops in one year, so that the utilization rate of the fertilizer can be improved, the use frequency of the fertilizer can be reduced, and the planting efficiency of the sugarcane can be improved.

Description

technical field [0001] The invention relates to the technical field of fertilizer production, in particular to a special fertilizer for sugarcane primary root zone and a preparation process thereof. Background technique [0002] Chemical fertilizers are essential in the cultivation and planting of sugarcane, which is related to the growth status and final yield of sugarcane. However, the increase in the application of chemical fertilizers has led to an increase in the frequency of use of chemical fertilizers, which has increased the workload of sugarcane cultivation. On the other hand, although the application of chemical fertilizers has increased, the utilization rate of chemical fertilizers has not been effectively improved, which also leads to increased production costs and an unsatisfactory input-output ratio. Contents of the invention [0003] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the a...
