Problems solved by technology

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:

[0040] 5% thermoplastic resin coated urea 40kg

[0041] 6% thermoplastic resin coated urea 20kg

[0042] Sulfur coated urea 360kg

[0043] Potassium sulfate compound fertilizer 350kg

[0044] Potassium sulfate 185kg

[0045] Diammonium phosphate 40kg

[0046] Zinc sulfate 5kg.

[0047] Preparation method: Put the above-mentioned raw materials into a blender and stir for 8 minutes, and mix well to get the product. 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:

[0050] 5% thermoplastic resin coated urea 30kg

[0051] 6% thermoplastic resin coated urea 30kg

[0052] Sulfur coated urea 275kg

[0053] Potassium sulfate compound fertilizer 350kg

[0054] Potassium sulfate 270kg

[0055] Diammonium phosphate 40kg

[0056] Zinc sulfate 5kg.

[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, belonging to the technical field of slow-release and controlled-release fertilizers. According to the fertilizer requirements of ginger and garlic, the present invention precisely compounded a certain proportion of 5% and 6% thermoplastic resin-coated urea, sulfur-coated urea, potassium sulfate compound fertilizer, potassium sulfate, diammonium phosphate and zinc sulfate. . The controlled-release fertilizer not only matches the nutrient release law of ginger and garlic, but also can reduce fertilizer loss, improve fertilizer utilization rate, and reduce the cost of controlled-release fertilizer. The controlled-release fertilizer is used for one-time fertilization without topdressing, reducing Reduced the labor intensity and labor cost of farmers.

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...
