Problems solved by technology

One of the biggest disadvantages of general silicon, calcium, magnesium, and potassium fertilizers is that they are easily fixed as slow-acting or ineffective after being applied to the soil. Silicon, calcium, magnesium, and potassium are not effective for crops.

Embodiment 1

[0015] Take 25% dolomite and 75% potassium feldspar by mass, mix and finely grind them to 180-300 mesh powder particles after purification, calcinate the powder particles at a high temperature of 1300-1400°C for 6 hours, and then rapidly cool them for 10 minutes , to produce highly active silicon, calcium, magnesium, potassium mixed materials. Then mix 4 parts of Lingshi snowflake blue gypsum and 1 part of humic acid evenly, finely grind to 180-300 mesh powder particles, take 1 part of the powder particles and mix 4 parts of silicon, calcium, magnesium and potassium After the parts are mixed, it is made into granules with a diameter of 1-3mm, which can be packaged after drying.

Embodiment 2

[0017] Take 35% dolomite and 65% potassium feldspar by mass, mix and finely grind them to 180-300 mesh powder particles after purification, calcinate the powder particles at a high temperature of 1300-1400°C for 10 hours, and then quench them for 5 minutes , to produce highly active silicon, calcium, magnesium, potassium mixed materials. Then mix 4 parts of Lingshi snowflake blue gypsum and 1 part of humic acid evenly, finely grind to 180-300 mesh powder particles, take 1 part of the powder particles and mix 4 parts of silicon, calcium, magnesium and potassium After the parts are mixed, it is made into granules with a diameter of 1-3mm, which can be packaged after drying.

Abstract

The invention discloses a production method of a high-activity medium element fertilizer. In the production method, activity of each element in a silicon calcium magnesium potassium fertilizer is activated by using a technology of quenching after mixed particles of dolomite and potassium feldspar are calcined at a high temperature; content of silicon calcium magnesium potassium and microelements in the fertilizer is increased by adding Lingshi compact grey gypsum full of regional character and humic acid; a total content of the elements of silicon calcium magnesium and potassium exceeds 60%; and the fertilizer which has the highest content of silicon calcium magnesium and potassium and the most comprehensive nutrition on the market is prepared. The f high-activity medium element fertilizer produced by the production method is a nutrition fertilizer, an adjustment fertilizer and a health-care fertilizer. Excerpt for providing the own nutrition elements of the fertilizer to plants, the fertilizer has the effects of improving soil structure, improving crop quality, promoting root-taking, promoting photosynthesis, and enhancing capacities of drought resistance, dry-hot wind resistance, cold resistance, low temperature resistance and disease and pest resistance of the crops.

Description

technical field [0001] The invention relates to a mineral fertilizer, in particular to a production method of a compound mineral fertilizer containing multiple nutritional elements such as silicon, calcium, magnesium, potassium, sulfur and humic acid. Background technique [0002] High activity medium element fertilizer is an important compound element mineral fertilizer containing silicon, calcium, magnesium, potassium, sulfur and humic acid, which can be used as base fertilizer or topdressing fertilizer. The basic fertilizer of compound fertilizer has good compatibility with various fertilizers. One of the biggest disadvantages of general silicon, calcium, magnesium, and potassium fertilizers is that they are easily fixed to be slow-acting or ineffective after being applied to the soil, and silicon, calcium, magnesium, and potassium are not effective for crops. Generally, the seasonal utilization rate is 15-20%. How to improve the production process to reduce costs and im...
