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...

Problems solved by technology

As for the improvement of saline-alkali land, at present, most of them are to eradicate saline-alkali soil and replace it with benign fertile soil, but this method has high cost, low efficiency, fast return to saline-alkali, and the eradicated saline-alkali soil is difficult to handle.

There is still no effective and economical way to control salt land
