Example Embodiment

[0012] Example 1

[0013] First weigh 275 parts of humic acid (parts by weight), trace elements (copper, zinc, iron, manganese, boron, molybdenum, etc.) or biological fertilizer (rhizobia, nitrogen-fixing bacteria, phosphate solubilizing bacteria, potassium solubilizing bacteria, etc.) 25 Parts (parts by weight); 700 parts (parts by weight) of high-quality fermented human, livestock, and poultry manure; spray appropriate water in the disc or drum granulator, granulate and sieve to reach the granular φ1-3mm organic fertilizer Standard granules are sent to the oven (or drying room) at 150℃, taken out when the moisture content is ≤8% during drying, and then sieved out the granules smaller than φ1mm. After the temperature drops to room temperature, weigh the organic fertilizer φ1- 790 parts (parts by weight) of 3mm particles, put into the drum granulator, spray water on the surface of the organic fertilizer particles while rolling, make the surface of the particles evenly wetted as th...

[0014] Example 2

[0015] First, weigh 150 parts of humic acid (parts by weight), trace elements (copper, zinc, iron, manganese, boron, molybdenum, etc.) or biological fertilizer (rhizobia, nitrogen-fixing bacteria, phosphorus solubilizing bacteria, potassium solubilizing bacteria, etc.) 10 Parts (parts by weight); 600 parts (parts by weight) of high-quality fermented human, livestock, and poultry manure; spray appropriate water in the disc or drum granulator, granulate and sieve to achieve a granular φ1-3mm organic fertilizer Standard granules are sent to the oven (or drying room) at 150℃, taken out when the moisture content is ≤8% during drying, and then sieved out the granules smaller than φ1mm. After the temperature drops to room temperature, weigh the organic fertilizer φ1- 780 parts (parts by weight) of 3mm particles, put them into the drum granulator, spray water on the surface of the organic fertilizer particles while rolling, make the surface of the particles evenly wette...

Abstract

The invention relates to a manufacturing technique of plant drought-resistant water-preserving organic fertilizer, comprises the following steps: weighing component weight parts: humic acid 150-300, microelement or biological bacterium fertilizer 10-30, fermentative excrement of human, livestock, poultry 600-700; mixing granulating and screening to get particles which phi 1-3 mm, baking, rescreening; putting 780-820 parts in a pelletizer, spraying water on particle surface when rolling, then feeding to a rotary drum with 18-22 parts of water-preserving agent, coating in the rotary drum pelletizer; feeding coated organic fertilizer in a rotary drum pelletizer with 20-40 parts of bentonite, when the bentonite separate the organic fertilizer fully, screening excess bentonite; feeding coated organic fertilizer sticking with bentonite after screening in a dryer, through sampling and detecting during drying procedure, when water content gets to less than 8%, taking out all organic fertilizer, airing to normal temperature to get products. The invention has advantages of drought-resistant and water-preserving, good nutrient preserving capability, low cost, simple and convenient application method.

Description

technical field [0001] The invention relates to a fertilizer production process, in particular to a plant drought-resistant and water-retaining organic fertilizer production process. Background technique [0002] my country is one of the 13 seriously water-scarce countries in the world, and its per capita water consumption is only a quarter of the world average, ranking 110th in the world. The country's arid and semi-arid areas account for about 80% of the country's land area, and the dry land without irrigation conditions accounts for about 65% of the cultivated land area among the 1.6 billion mu of cultivated land. Long-term drought and water shortage, drought resistance and seedling preservation have almost become the central task of spring sowing in these arid and semi-arid areas every year. According to statistics from 1991 to 1995, the average annual drought-affected area in the country reached 450 million mu, and the annual grain production due to drought decreased b...
