However, there are still two main problems in the direct application of these slow / controlled release fertilizers to the production of ginger and garlic. One is that the price is too high for farmers to accept; the other is that the ratio of nutrient elements and the law of nutrient release are not targeted.

Embodiment 1
[0039] Special controlled-release fertilizer for ginger and garlic, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide content are 20%, 8%, and 14% respectively, all of which are percentages by mass. The raw material components are as follows:
[0047] Preparation method: Put the above-mentioned raw materials together in a blender and stir for 8 minutes, and mix thoroughly. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.
Embodiment 2
[0049] Special controlled-release fertilizer for ginger and garlic, total nutrients: nitrogen, phosphorus pentoxide, and potassium oxide are 17%, 8%, and 18% by mass, respectively. The raw material components are as follows:
[0057] The preparation method is the same as in Example 1.

Abstract
The invention relates to a special controlled release fertilizer for ginger and garlic and a preparation method thereof and belongs to the technical field of sustained release fertilizer and controlled release fertilizer. According to the rule of the fertilizer requirement of the ginger and garlic, the invention is prepared by exactly remixing 5 percent and 6 percent thermoplastic resin coated urea, sulfur coated urea, potassium sulfate complex fertilizer, the potassium sulfate, diammonium phosphate and zinc sulfate according to certain proportion. The nutrient release rule of the controlled release fertilizer is in accordance with the nutrition absorption rule of the ginger and garlic, which can reduce the loss of the fertilizer, improves the fertilizer utilization rate and reduces the cost of the controlled release fertilizer, and no more fertilization is required after one time of the fertilization of the controlled release fertilizer, which reduces the labor intensity of the farmer and the labor cost.
Description
technical field [0001] The invention relates to a method for producing a special controlled-release fertilizer for crops by using coated sulfur and coated thermoplastic resin, in particular to a special controlled-release fertilizer for ginger and garlic and a manufacturing method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] China is the main producer and exporter of ginger and garlic in the world. At present, my country's garlic planting area is about 260,000 hectares, accounting for 1 / 2 of the world's garlic area, with an annual output of 2 million tons. It is an important export agricultural product; in recent years, my country's ginger production and export have also shown a significant growth trend. [0003] Both ginger and garlic are crops whose main products are rhizomes. They are shallow-rooted plants with underdeveloped root systems and weak fertilizer absorption capacity. Therefore, the amount of f...
