Embodiment 1

[0047] Embodiment 1: special controlled-release fertilizer for cucumber, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 22%, 10%, 15%, all are percentage by mass. The raw material components are as follows:

[0048] 5% thermoplastic resin coated potassium nitrate 100kg

[0049] 6% thermoplastic resin coated potassium nitrate 60kg

[0050] 7% thermoplastic resin coated potassium nitrate 100kg

[0051] 5% thermoplastic resin coated urea 100kg

[0052] 7% thermoplastic resin coated urea 120kg

[0053] 8% thermoplastic resin coated urea 100kg

[0054] Potassium sulfate compound fertilizer 320kg

[0055] Diammonium Phosphate 95kg

[0056] Zinc sulfate 5kg.

[0057] The preparation method is that the above-mentioned raw materials are put into a blender and stirred for 5-10 minutes, and fully mixed to obtain the product. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.

Embodiment 2

[0058] Embodiment 2: special controlled-release fertilizer for cucumber, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 22%, 7%, 18%, all are percentage by mass. The raw material components are as follows:

[0059] 5% thermoplastic resin coated potassium nitrate 120kg

[0060] 6% thermoplastic resin coated potassium nitrate 105kg

[0061] 7% thermoplastic resin coated potassium nitrate 100kg

Abstract

The invention relates to a special controlled release fertilizer for cucumbers and a preparation method thereof. The special controlled release fertilizer is synthesized by 5 percent of thermoplastic resin coated potassium nitrate, 6 percent of thermoplastic resin coated potassium nitrate, 7 percent of thermoplastic resin coated potassium nitrate, 5 percent of thermoplastic resin coated carbamide, 7 percent of thermoplastic resin coated carbamide, 8 percent of thermoplastic resin coated carbamide, diammonium phosphate, etc. The special controlled release fertilizer for the cucumbers of the invention is served as a base fertilizer to be applied only one time before transplanting the cucumbers without dressing, thus acquiring relatively good yield-increasing effect, improving the utilization ratio of the fertilizer and saving labor.

Description

technical field [0001] The invention relates to a method for producing a special controlled-release fertilizer for crops by using a thermoplastic resin coating, in particular to a special controlled-release fertilizer for cucumbers produced by using thermoplastic resin coated potassium nitrate and thermoplastic resin coated urea and a manufacturing method thereof, which belongs to slow / Controlled release fertilizer technical field. Background technique [0002] Cucumber is one of the main vegetable varieties in my country. Statistics at the end of the 20th century show that the cultivated area of ​​cucumber in my country has reached nearly 3 million hectares, of which cucumbers in protected areas account for about 42%, and the cultivated area accounts for more than 70% of the total area of ​​cultivated vegetables in protected areas. . Make fresh cucumber production realize annual supply. [0003] Cucumber is an unlimited growth crop, as long as the temperature, light, wat...
