Problems solved by technology

However, at present, my country's wheat-specific fertilizers only use crop species as the main reference factor, ignoring important factors such as soil type and farming methods for wheat growth.
The Huanghuai Plain covers an area of ​​6,000 square kilometers. It is a key agricultural production area in my country to promote straw returning to the field and promote the comprehensive utilization of farmland straw resources. The traditional fertilization mode can no longer meet the current needs of wheat production in the Huanghuai Plain.

Embodiment 1

[0027] Embodiment 1: a special fertilizer for wheat, with urea, monoammonium phosphate, potassium chloride and weathered coal as basic raw materials, granulation additives are fertilizer adhesives and activation additives, the mass parts of each component are: 29 parts of urea , 20 parts of monoammonium phosphate, 16 parts of potassium chloride, 30 parts of weathered coal, 4 parts of fertilizer adhesive and 1 part of activation additive; described fertilizer adhesive is activated clay, and described activation additive is potassium hydroxide .

[0028] The preparation method is as follows:

[0029] Batching and granulation: drying the raw materials of urea, monoammonium phosphate and potassium chloride to a water content of ≤2wt%, and drying the weathered coal raw materials to a water content of ≤20wt%. After the raw materials are dried, they are pulverized so that the particle diameter of each raw material component is 0.1-0.3 mm. The dried and pulverized raw materials are ...

Embodiment 2

[0036] A special fertilizer for wheat, the mass parts of each component are: 19 parts of urea, 20 parts of monoammonium phosphate, 16 parts of potassium chloride, 40 parts of weathered coal, 3.5 parts of fertilizer adhesive and 1.5 parts of activation additive; The fertilizer adhesive is activated clay, and the activation additive is potassium hydroxide.

[0037] The preparation method is the same as in Example 1. The nutrient content of special fertilizer for wheat is N:P 2 o 5 : K 2 O=9:8:9.

[0038] This special fertilizer for wheat is suitable for use as a base fertilizer in land with medium soil fertility, and the application rate is 1500kg / hm 2 , 15kg of urea can be applied at the jointing stage. Compared with farmers' customary fertilization method, the yield is increased by about 10%.

Embodiment 3

[0040] A special fertilizer for wheat, the mass parts of each component are: 11 parts of urea, 22 parts of monoammonium phosphate, 18 parts of potassium chloride, 44 parts of weathered coal, 3 parts of fertilizer adhesive and 2 parts of activation additive; The fertilizer adhesive is activated clay, and the activation additive is potassium hydroxide.

[0041] The preparation method is the same as in Example 1. The nutrient content of special fertilizer for wheat is N:P 2 o 5 : K 2 O=7:9:10.

[0042]This special fertilizer for wheat is suitable for use as a base fertilizer in plots with high basic soil fertility, and the application rate is 1500kg / hm 2 , 15kg of urea can be applied at the jointing stage. Compared with farmers' customary fertilization method, the yield can be increased by about 9%.

Abstract

The invention relates to a special fertilizer for wheat under the condition of full-amount straw returning in Huanghuai plain and a preparation method thereof, according to the fertilizer-required characteristic of wheat growth and development under the condition of full-amount straw returning in Huanghuai plain, urea, monoammonium phosphate, potassium chloride and weathered coal are utilized as basic raw materials, a composite granulation additive consisting of an adhesive and an activatiing agent is added, and then the fertilizer can be obtained through disc plate granulation. The wheat special fertilizer of the invention has the advantages of simple production process, low cost, environment protection, high utilization factor and obvious production increase effect, and is applicable tothe requirement of wheat production under the condition of full-amount straw returning in Huanghuai plain.

Description

technical field [0001] The invention relates to the field of fertilizer production, in particular to the formulation and preparation method of special wheat fertilizer under the condition of full straw returning to the field in Huanghuai Plain. Background technique [0002] In recent years, the focus of research and development and application of new fertilizers at home and abroad has shifted from simple fertilizers to compound fertilizers. As a kind of compound fertilizer, special fertilizer for crops is very popular in the fertilizer market because of its richer types of nutrient elements, more reasonable ratio and more convenient application. Wheat is the second largest food crop in my country. Therefore, the research and development and application of special fertilizers for wheat have always been paid attention to. Potassium chloride, potassium sulfate, zinc sulfate, manganese sulfate, sodium aluminate, sodium molybdate, ferrous sulfate, borax, rare earth nitrate, medic...
