Problems solved by technology

2. Poor environmental protection, resulting in serious soil compaction
Excessive application of chemical fertilizers will deteriorate the physical and chemical properties of the soil, block the soil pores, destroy the soil aggregate structure, and cause the imbalance of soil nutrients, compaction, pollution and decline in fertility
At the same time, excessive application of chemical fertilizers can also lead to groundwater pollution and air pollution, which is also a threat to human health.
3. The quality of crops is low, which directly threatens the safety of human life

Embodiment 1

[0011] It is composed of the following raw materials by weight: 40% of ammonium humate; 20% of sodium selenite; 40% of silicon micropowder.

[0012] The preparation steps of humic acid fertilizer are as follows:

[0013] The raw coal is pulverized to 30-60 mesh, and at 20°C, the raw coal and the directly ammoniated ammonia are added in the reaction tank according to the ratio of the humic acid content in the raw coal to the directly ammoniated ammonia source weight ratio of 6:1. Source: nitrogen ammonia, ammonia water and carbonized ammonia water are stirred, and the temperature is controlled at 40°C; the reaction time is 0.5 hours, and the reaction product is placed for 24 hours; Dry at ℃ to obtain ammonium humate, and mix the prepared humic acid product with sodium selenite or silicon micropowder in the above ratio to obtain a finished product. Microsilica is a commercially available product.

Embodiment 2

[0015] It is composed of the following raw materials by weight: 60% of potassium humate; 5% of sodium selenite; 35% of silicon micropowder.

[0016] The preparation steps of humic acid fertilizer are as follows:

[0017] The raw coal is pulverized to a temperature of 30° C. In the reaction tank, the raw coal and potassium carbonate are added in a ratio of 6:1 by weight ratio of the humic acid content in the raw coal to the ammonia source of direct ammoniation, and the temperature is controlled at 60 °C. ℃; the reaction time is 0.5 hour, and the product after the reaction is placed for 72 hours; stirring is granulated, and the granulated reactant is placed in a drying oven and dried at 55 ℃ to obtain potassium humate, and the prepared humic acid product Mixed with the above proportion of sodium selenite or silicon micropowder to obtain the finished product.

Embodiment 3

[0019] It is composed of the following raw materials by weight: 50% of sodium humate; 10% of sodium selenite; 40% of silicon micropowder.

[0020] The preparation steps of humic acid fertilizer are as follows:

[0021] The raw coal is pulverized to the point where, at 25°C, the raw coal and sodium carbonate are added in the reaction tank according to the ratio of the humic acid content in the raw coal to the weight ratio of the ammonia source directly ammoniated to be 6:1, and the temperature is controlled at 50 °C. ℃; the reaction time is 0.5 hours, and the product after the reaction is placed for 168 hours; stirring is granulated, and the granulated reactant is placed in a drying oven and dried at 55 ℃ to obtain ammonium humate, and the prepared humic acid product Mixed with the above proportion of sodium selenite or silicon micropowder to obtain the finished product.

Abstract

A silicon-selenium humate fertilizer is characterized in that: the fertilizer consists of the raw materials with the following weight percentage: 40 to 60 percent of humic acid, 5 to 20 percent of sodium selenite and 20 to 40 percent of silicon micropowder. The humic acid is ammonium humate, potassium humate or sodium humate. The silicon-selenium humate fertilizer, which is widely used in crops such as wheat, corn, soybean, melon, fruit and vegetable, has outstanding effects in improving soil, adjusting soil solution acidity, reinforcing chemical fertilizer fertility and reducing fertilizing cost.

Description

technical field [0001] The invention relates to the field of agricultural chemical fertilizers, in particular to a humic acid silicon selenium fertilizer. Background technique [0002] With the rapid development of the chemical industry, the production and application of various fertilizers have continued to increase, which has played an important role in promoting the development of agricultural production. However, with the continuous increase in the amount of chemical fertilizer application, the shortcomings of its application are increasingly prominent, mainly in the following three aspects: 1. It is the increase in the cost of fertilization caused by high input and low output. At present, the utilization rate of nitrogen fertilizer in my country's chemical fertilizer field is only 15-40%, the utilization rate of phosphate fertilizer is only 10-20%, and the utilization rate of potassium fertilizer is only 20-50%. 2. It is green and environmentally friendly, resulting in...
