Problems solved by technology

Compared with ordinary fertilizers, the nutrients of these fertilizers have a certain slow-release effect, but because the coating materials are water-soluble, their nutrient release speed is mainly affected by water. Large crops have poor adaptability

Embodiment 1

[0047] Embodiment 1: special controlled-release fertilizer for wheat, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 24%, 10%, 13%, all are percentage by mass. The raw material components are as follows:

[0048] 6% thermoplastic resin coated urea 45kg

[0049] 7% thermoplastic resin coated urea 30kg

[0050] 8% thermoplastic resin coated urea 15kg

[0051] Sulfur coated urea 300kg

[0052] Potassium chloride compound fertilizer 550kg

[0053] Potassium chloride 50kg

[0054] Zinc sulfate 10kg.

[0055]Preparation method: Put the above-mentioned raw materials into a blender and stir for 5-10 minutes, and mix thoroughly. Then the mixed fertilizer is sent to the metering and packaging machine for metering and packaging.

Embodiment 2

[0056] Embodiment 2: special controlled-release fertilizer for wheat, total nutrient: nitrogen, phosphorus pentoxide, potassium oxide content are respectively 20%, 10%, 20%, all are percentage by mass. The raw material components are as follows:

[0057] 6% thermoplastic resin coated urea 45kg

[0058] 7% thermoplastic resin coated urea 30kg

[0059] 8% thermoplastic resin coated urea 15kg

[0060] Sulfur coated urea 260kg

[0061] Potassium chloride compound fertilizer 300kg

[0062] Diammonium phosphate 100kg

[0063] Potassium chloride 240kg

[0064] Zinc sulfate 10kg.

[0065] The preparation method is the same as in Example 1.

Abstract

The invention relates to a special controlled-release fertilizer for wheat and a preparation method thereof, and belongs to the technical field of slow-release and controlled-release fertilizers. According to the fertilizer requirements of wheat, the present invention precisely compounded 5%, 6% and 7% thermoplastic resin-coated urea, sulfur-coated urea, potassium chloride compound fertilizer, potassium chloride, diammonium phosphate and zinc sulfate, Form a special formula controlled release fertilizer for wheat. The controlled-release fertilizer not only matches the nutrient release law with the nutrient absorption law of wheat, but also reduces the cost of the controlled-release fertilizer. The controlled-release fertilizer is used to apply fertilizer once before wheat sowing, and there will be no topdressing in the future, which reduces the labor intensity of farmers. and labor costs.

Description

technical field [0001] The invention relates to a special controlled-release fertilizer for crops produced by coated sulfur and coated thermoplastic resin, in particular to a special controlled-release fertilizer for wheat and a manufacturing method thereof, belonging to the technical field of slow / controlled release fertilizers. Background technique [0002] Wheat is one of the most important food crops in the world, and more than one-third of the world's population takes wheat as their main ration. Wheat is also the most important commodity grain in the world. The annual trade volume of world wheat is about 100 million tons, more than the sum of all other grains. China is the world's largest wheat producer and wheat consumer, and is the center of world wheat production and consumption. [0003] According to the existing fertilizer varieties and fertilization techniques, my country mainly adopts the combination of base fertilizer and topdressing in wheat fertilization. In ...
