Embodiment 1

[0038]Embodiment 1: The weathered coal, lignite and peat with a humic acid content of more than 50% and a moisture content of less than 30% are selected and pulverized into 80-120 mesh coal powder. Coal powder: nitric acid: potassium carbonate: diflubenzuron: diflubenzuron: biclobutrazol: water = 100~120: 3~8: 2~5: 0.03~0.06: 0.01~0.05: 0.05~0.07: 0.02~ 0.08: Raw material weight ratio of 200-320 is prepared. First, take 100-120 kg of coal powder and 200-300 kg of water into the reactor for stirring, then add 3-8 kg of nitric acid into the reactor, stir, and heat at a temperature of 60°C-70°C. React for 60 minutes to fully oxidize the raw materials into small molecular organic substances that are easily absorbed by plants, then add 5-8 kg of potassium carbonate and stir, heat to 70-85°C, and react for 60 minutes to react all the combined humic acid. get the reaction material. The moisture content of the reaction material is lower than 30% (air-dried and dehydrated), and the p...

Embodiment 2

[0039] Embodiment 2: Different from Example 1, the weight ratio of raw materials is coal powder: nitric acid: potassium carbonate: diflubenzuron: diflubenzuron: bijiu: paclobutrazol: water=110~120: 5~6: 3~4 : 0.04-0.05: 0.02-0.04: 0.06-0.07: 0.04-0.07: 270-320. The rest of the steps are the same, so they will not be repeated here.

Embodiment 3

[0040] Embodiment 3: Different from Example 1, the raw material weight ratio is coal powder: nitric acid: potassium carbonate: diflubenzuron: diflubenzuron: bijiu: paclobutrazol: water=118: 5: 3: 0.04: 0.03: 0.06 :0.06:300. The rest of the steps are the same, so they will not be repeated here.

[0041] In a word, the production process of the present invention is simple and practical, saves energy and time, does not pollute the environment, is low in cost, has a good promotion effect on ecological environments such as soil, crops, and water systems, enhances the drought resistance and drought resistance of crops, and has a certain degree of prevention and control of diseases and insect pests. role, can be promoted and used.

Abstract

The invention provides a process for producing a special humic acid fertilizer for grassland ecology by using coal. The fertilizer is prepared from such raw materials as coal powder, nitric acid, potassium carbonate, diflubenzuron, chlorbenzuron, daminozide, paclobutrazol and water in a weight ratio of (100-120):(3-8):(2-5):(0.03-0.06):(0.01-0.05):(0.05-0.07):(0.02-0.08):(200-320) through the following steps of: reacting, stirring, heating, mixing and granulating. The process has the following advantages: the process is simple and practical, is energy-saving and time-saving, is environmentally-friendly, is low in cost, has a good effect on promoting such ecological environments as soil, crops and water systems, can conduce to enhancing the drought, cold and disease resistance of grassland plants and has a certain effect on controlling plant diseases and insect pests.

Description

technical field [0001] The invention belongs to a kind of humic acid grassland ecological special fertilizer produced by coal. Background technique [0002] Grassland is the largest terrestrial ecosystem in my country. my country's grasslands start from the west of the Songliao Plain in the east, pass through the Inner Mongolia Plateau, the west of the Loess Plateau, and reach the Qinghai-Tibet Plateau of nearly 400 million hectares, accounting for about 41.7% of the country's land area, which is larger than the combined area of ​​forest land and farmland. It is a vast green land resource. But up to now, more than 90% of the grasslands have been degraded, and more than 50% of the grasslands have been seriously degraded. As early as 2006, the area of ​​degraded and desertified grassland in Xilin Gol League had reached 184.46 million mu, accounting for 64% of the usable grassland area from 48.6% in 1984, and degraded and desertified at an annual growth rate of 10%. Nearly 75...
