Embodiment 1

[0015] Embodiment 1: a kind of anti-repeatable soil-friendly special fertilizer for peanuts of the present invention is calculated by the following weight percentages: urea 7.5%, ammonium chloride 16.1%, monoammonium phosphate 22.7%, potassium chloride 16.6% and clay mineral particle control Release agent 37.1% made of: of which,

[0016] 1), mixing urea, ammonium chloride and clay mineral particle controlled release agent together to make initial material;

[0017] 2), mixing potassium chloride with the initial material to make a premix;

[0018] 3) Mix the monoammonium phosphate and the premix evenly to make granules;

[0019] 4) Dry and sieve the granules so that more than 90% of the granules with a particle size of 3.35-5.6mm are finished products;

[0020] The clay mineral particle controlled release agent is composed of agricultural sodium tetraborate and bauxite tailings slag with a weight ratio of 0.015:0.8;

[0021] The mass content of urea nitrogen is 46.4%, the m...

Embodiment 2

[0022] Embodiment 2: a kind of soil-friendly special fertilizer for anti-heavy cropping of the present invention is calculated by the following weight percentages: urea: 1%, ammonium chloride 23.5%, monoammonium phosphate 35.9%, potassium chloride 6.7% and clay mineral particles Controlled release agent 32.9%, the preparation method is the same as

[0023] Example 1.

Embodiment 3

[0024] Embodiment 3: a kind of anti-heavy cropping soil-friendly special fertilizer for peanuts of the present invention is calculated by the following weight percentages: urea: 15.2%, ammonium chloride 1.5%, monoammonium phosphate 20.7%, potassium chloride 18.6% and clay mineral particles Controlled release agent 44% is made, and preparation method is the same as embodiment 1.

Abstract

The purpose of the invention is to provide a continuous cropping-resistant and soil-friendly special fertilizer for peanuts. The fertilizer is prepared from 1-16.2% of urea, 2-24% of ammonium chloride, 10-36.6% of monoammonium phosphate, 1-16.6% of potassium chloride and 33-44.5% of a clay mineral particle controlled release agent. The continuous cropping-resistant and soil-friendly special fertilizer for peanuts has the advantages of rich raw materials, easiness in production and preparation, high production efficiency, low cost, easiness in promotion and application, effectiveness in being used for plantation of continuous cropping peanuts, low content of nitrogen, phosphorus and potassium nutrients, high activity, provision of good nutrients for peanuts, meeting the needs of peanuts formedium and trace elements, simple preparation method, low cost, good use effect, effectiveness in peanut plantation, no environmental pollution, ensuring of high yielding and high harvesting, and great economic and social benefits.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a soil-friendly special fertilizer for peanuts resistant to heavy cropping. Background technique [0002] Peanut is the main oil crop, the planting area has been expanding year after year, and perennial planting brings serious obstacles such as dead seedlings and other heavy cropping, which has a great impact on production, high agricultural investment costs and reduced returns; ordinary chemical fertilizers are high in input, high in pollution and low in yield It is also one of the main reasons for the high input and low output of chemical fertilizers. [0003] On the other hand, the resource utilization of bauxite tailings has always been the main research direction of bauxite flotation enterprises, but at present, the resource utilization of bauxite tailings is mostly concentrated in industries such as building bricks and tiles, and lacks research and application in agriculture , so whether to...
