Problems solved by technology

Long-term single application of chemical fertilizers to solanaceous vegetables will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, resulting in a decline in production capacity, while the fertilizer effect of organic fertilizers is slow
In the prior art, most of the crop straws are burned directly in the field, which seriously damages the beneficial microorganisms in the soil and is not conducive to the growth of crops. In addition, burning straws will produce a large amount of harmful gases such as CO2 and SO2, polluting the environment

preparation example Construction

[0014] The preparation method of biogas slurry solidified organic fertilizer of the present invention includes the following steps:

[0015] (1) The crop stalks are pulverized to 1-5 cm in a pulverizer, and then sent to a mixing tank to mix with the biogas slurry for aerobic fermentation. The internal temperature of the pile rises to 55-70°C for 7-12 days. Eliminate odor and reach harmlessness standards. Since straw has good water absorption characteristics and has good porosity after water absorption, it is conducive to the enrichment of nutrients in the subsequent aerobic fermentation process.

[0016] (2) The above-mentioned materials are sent to an aerobic fermentation tank to which ammonium bicarbonate has been added for double fermentation to increase the content of organic acids in the biogas slurry. The aerobic fermentation tank maintains a humidity of 50-70% and a carbon-nitrogen ratio It is 25-35:1 and sufficient oxygen. In this process, clay and phosphate fertilizer a...

Embodiment 1

[0020] Prepare a solidified organic fertilizer from solanaceous fruit to increase biogas slurry according to the following steps:

[0021] (1) Crush 600 parts of dry straw to 1-3 cm, and send it to a mixing tank to mix with 100 parts of biogas slurry for aerobic fermentation, the temperature in the mixing tank is 55°C;

[0022] (2) Then it is sent to an aerobic fermentation tank with 200 parts of ammonium bicarbonate for double fermentation. During the process, 5 parts of clay and 1 part of phosphate fertilizer are added. The humidity in the aerobic fermentation tank is maintained at about 55%. The ratio is about 30:1, and sufficient oxygen is guaranteed;

[0023] (3) Mix the above-mentioned double fermentation product with 200 parts of urea, 10 parts of superphosphate, 10 parts of magnesium sulfate, 10 parts of zinc sulfate, 10 parts of borax and 1 part of potassium indole butyrate, and then send it to the granulator The granulation is carried out, and the finished product is made ...

Embodiment 2

[0026] Prepare a solidified organic fertilizer from solanaceous fruit to increase biogas slurry according to the following steps:

[0027] (1) Crush 700 parts of dry straw to 2-4 cm, and send it to a mixing tank to mix with 100 parts of biogas slurry for aerobic fermentation, the temperature in the mixing tank is 65°C;

[0028] (2) Then it is sent to an aerobic fermentation tank with 300 parts of ammonium bicarbonate for double fermentation. During the process, 8 parts of clay and 2 parts of phosphate fertilizer are added. The humidity in the aerobic fermentation tank is maintained at about 60%. The ratio is about 30:1, and sufficient oxygen is guaranteed;

[0029] (3) Mix the above-mentioned double fermentation product with 200 parts of urea, 20 parts of superphosphate, 20 parts of magnesium sulfate, 20 parts of zinc sulfate, 20 parts of borax and 3 parts of potassium indole butyrate and then send them to the granulator The granulation is carried out, and the finished product is ma...

Abstract

The invention provides a biogas slurry curing organic fertilizer for solanberry yield increase and a preparation method thereof. The biogas slurry curing organic fertilizer comprises 600-800 parts of dry straw, 100 parts of biogas slurry, 200-400 parts of ammonium carbonate, 5-10 parts of clay, 1-3 parts of phosphate fertilizer, 200-250 parts of urea, 10-30 parts of superphosphate, 10-20 parts of magnesium sulfate, 10-20 parts of zinc sulfate, 10-20 parts of borax and 1-5 parts of indole-3-butyric acid potassium salt. According to the invention, the fertilizer utilization ratio of solanberry crops is improved.

Description

Technical field [0001] The invention relates to a biogas slurry solidified organic fertilizer capable of increasing the yield of solanaceous fruit crops and a preparation method thereof, and belongs to the field of fertilizer processing. technical background [0002] Solanaceous vegetables are rich in vitamins, mineral elements, carbohydrates, organic acids and a small amount of protein, all of which are essential nutrients for the human body. Due to its high yield, long growing and supply seasons, wide range of economic utilization, and widespread cultivation, solanaceous fruit vegetables occupy a large proportion of fruits and vegetables. Long-term single application of chemical fertilizers to solanaceous vegetables will cause long-term problems such as soil compaction, nutrient imbalance, and poor physical properties, resulting in a decline in production capacity, and organic fertilizer has a slower fertilizer effect. In the prior art, most crop straws are burned directly...
