Embodiment 1

[0060] The preparation of embodiment 1 soil remediation active organic fertilizer

[0061] Prepare as follows:

[0062] 1. Preparation of cakes containing active free amino acids:

[0063] Use 1,000 kg of soybean meal as raw material, add 5,000 kg of water to soak, heat to 50°C in an enamel tank, and stir for 1 hour at a speed of 20 rpm. Use potassium hydroxide aqueous solution to control the pH value at 7.5, and then add plant proteolytic enzyme 5 kg, and stir evenly in an enamel tank, keep the temperature at 55°C, carry out enzymatic hydrolysis for 24 hours, raise the temperature to 80°C, concentrate to 50% of the original weight under negative pressure, absorb with 1000 kg of soybean meal, and dry at 80°C to a water content of 12- 15%, to obtain enzyme-hydrolyzed amino acids containing more than 30% of amino acids and more than 12% of active free amino acids. The content is: (detected by the copper sulfate salting-out method) containing about 12% of free amino acids, orga...

Embodiment 2

[0069] The preparation of embodiment 2 soil remediation active organic fertilizers

[0070] Prepare as follows:

[0071] 1. Preparation of cakes containing active free amino acids:

[0072] Use 1,000 kg of soybean meal as raw material, add 5,500 kg of water to soak, heat to 60°C in an enamel tank, and stir for 1 hour at a speed of 15 rpm. Use potassium hydroxide aqueous solution to control the pH value at 7.5, and then add plant proteolytic enzyme 7. kg, and stir evenly in an enamel tank, keep the temperature at 55°C, carry out enzymatic hydrolysis for 20 hours, raise the temperature to 80°C, concentrate to 50% of the original weight under negative pressure, absorb with 1000 kg rapeseed meal, and dry at 80°C to contain water 12-15%, to obtain enzyme-hydrolyzed amino acids containing more than 30% of amino acids and more than 12% of active free amino acids. The content is: (detected by the copper sulfate salting-out method) containing about 12% of free amino acids, organic ni...

Embodiment 3

[0078] Application of embodiment 3 soil remediation active organic fertilizer in promoting crop growth, improving yield and agricultural product quality

[0079] The active organic fertilizer for soil remediation prepared by the method of Example 1 of the present invention has been tested in Kaifeng, Henan, Miluo, Hunan, Hanshou, Hainan and other places since the research and development. The demonstration results of the soil remediation active organic fertilizer prepared by the invention all achieved very good results, which are mainly reflected in:

[0080] 1. Watermelon can increase the sugar content by more than 2 degrees.

[0081] 2. Lycium barbarum can increase the sugar content by 1.1 degrees.

[0082] 3. Sugarcane can increase the sugar content by 2.7%, reduce reducing sugar by 0.3%, increase the gravity purity of cane juice by 7%, and improve the quality of cane juice.

[0083] 4. Top-dressing lychees after flowering fades can promote flowering and preserve fruit, w...

Abstract

The invention discloses a preparation method, a product and application of a soil remediating active organic fertilizer. The preparation method provided by the invention comprises the following steps: hydrolyzing caked dregs by using an enzyme to obtain the caked dregs containing active free amido acids, and then carrying out mixed fermentation on hydrilla soil, yellow bran, shell powder, bone meal, shrimp and crab shell meal by use of ferment bacteria to obtain organic fermented materials; finally, blending the caked dregs containing the active free amido acids with the organic fermented materials and adding a soil enzyme, thereby obtaining the active organic fertilizer for soil remediation which is up to the national microbial fertilizer standards. The soil remediating active organic fertilizer provided by the invention is capable of improving the fertilizer utilization rate and the percent conversion of crop nutrients; according to practices, the utilization rate of the fertilizer can be increased by 1.5-1.8 times, and therefore, the effects of over production, quality improvement, yield increase and good harvest can be achieved. Importantly, the product of the preparation method provided by the invention is capable of effectively improving the soil hardening condition, recovering the gas-solid-liquid ratio of the arable soil, forming the granular structure, improving the water retention capacity, proliferating the beneficial bacteria and activating soil.

Description

technical field [0001] The invention relates to a soil repairing active organic fertilizer and a preparation method thereof, in particular to a soil repairing active organic fertilizer for improving soil and controlling compaction and a preparation method thereof. The invention belongs to the fields of agricultural environmental protection and planting fertilizer manufacture. Background technique [0002] In recent decades, various reasons have formed the habit of partial application of chemical fertilizers in agricultural planting, resulting in soil acidification, soil compaction, quality degradation, insufficient organic matter content, water and fertilizer retention, and decreased air permeability. According to the survey, the polluted cultivated land in our country is as many as 1.5 billion mu, 32.5 million mu is irrigated with sewage, and 2 million mu of farmland is occupied and destroyed by solid waste, accounting for more than 10% of the cultivated land area. [0003...
