Fertilizer produced by using coal special for improving humic acid salt licks

Abstract

The invention provides a fertilizer produced by using coal special for improving humic acid salt licks. The fertilizer comprises the following components in parts by weight: 0.02-0.08 part of daminozide, 0.05-0.09 part of ethephon and 100-120 parts of a humic acid reactant, and the pH of the fertilizer is 4-5.5. A method for preparing the fertilizer comprises the following steps of: smashing weathered coal lignite and peat of which the humic acid contents are over 50 percent and the water content are less than 30 percent into coal powder of 80-120 meshes; adding 100-120 kilograms of coal powder and 200-300 kilograms of water into a reaction kettle, and stirring; adding 3-5 kilograms of ammonium nitrate into the reaction kettle; stirring; heating to 60-70 DEG C; reacting for 60 minutes; adding 5-6 kilograms of potassium hydroxide, and stirring; heating to 70-85 DEG C; reacting for 60 minutes; stirring; hermetically reacting at the temperature of 60 DEG C for 20 minutes till the pH is 4-5.5; adding 0.02-0.08 kilogram of daminozide and 0.05-0.09 kilogram of ethephon; stirring; and granulating and drying to obtain the fertilizer. Due to the adoption of the fertilizer, salt licks can be effectively improved; and the fertilizer has the advantages of easy and practical process, freeness from environmental pollution, low extraction cost, high raw material utilization ratio and high fertilizer utilization ratio.

Description

technical field

[0001] The invention belongs to a special fertilizer for the improvement of humate and alkali produced by coal. Background technique

[0002] As mankind enters the 21st century, the development of science and technology has reached a new stage, which has greatly promoted the progress of social economy. On the other hand, the problems faced by mankind are still very prominent, such as climate change, land desertification, salinization, environmental pollution and so on. In developing countries, due to the increasing population and decreasing arable land, a large number of forests, grasslands, wetlands, etc. have been reclaimed as arable land for intensive management, destroying the original vegetation and soil structure, leading to land salinization. Ten years later, the population-environment-resource problems faced by the world will become more serious, and land desertification, soil erosion and salinization will gradually increase. It is estimated that th...

Examples

Embodiment 1

[0010] Embodiment 1: It contains 0.02-0.08 parts by weight of biju, 0.05-0.09 parts by weight of ethephon, and 100-120 parts by weight of humic acid reactants. Its pH is 4-5.5.

[0011] It is composed of the following process: choose weathered coal, lignite and peat with more than 50% humic acid content and less than 30% moisture, and crush them into 80-120 mesh coal powder, take 100-120 kg of coal powder, and 200-200 kg of water Add 300 kg to the reaction kettle and stir, add 3 to 5 kg of ammonium nitrate to the reaction kettle, stir, heat, the temperature is 60°C to 70°C, react for 60 minutes, and then add 5 to 6 kg of potassium hydroxide Stir, heat to 70-85°C, react for 60 minutes, stir, temperature 60°C, seal and react for 20 minutes, the moisture content of the reaction material is required to be controlled at 25-35%, the pH is 4-5.5, and then add 0.02-0.08 kg of ratio Jiuhe 0.05 ~ 0.09 kg of ethephon, stir and mix evenly, and then send the material to the granulator wit...

Embodiment 2

[0012] Embodiment 2: Different from Embodiment 1, it contains 0.04-0.07 parts by weight of perju, 0.06-0.08 parts by weight of ethephon, and the pH is 4.5. The rest of the steps are the same, so they will not be repeated here.

Embodiment 3

[0013] Embodiment 3: Different from Embodiment 1, it contains 0.05 parts by weight of biju and 0.07 parts by weight of ethephon. The pH is 5. The rest of the steps are the same, so they will not be repeated here.

[0014] In a word, the invention can effectively improve the saline-alkali land, and the process is simple and practical, does not pollute the environment, the extraction cost is low, and the utilization rate of raw materials and fertilizer efficiency are high, so it can be popularized and used.
