Embodiment 1

[0026] The embodiment of the present invention provides a straw biochar-based soil phosphorus active conditioner and a preparation method thereof, comprising the following steps:

[0027] Step 1. Take the crop straw: remove the sundries on the straw, clean up the soil and sand, and cut it into 3-5cm by cutting equipment;

[0028] Step 2, cleaning and filtering: cleaning the straw, and after the cleaning is completed, the straw is placed in water for immersion, and the soaking time is 30 minutes. It can decompose fungi and ammonia nitrogen degrading bacteria. Sulfur-fixing agent can remove sulfur oxides in soil during the control and treatment of soil pollutants. Polyethylene wax can enhance the viscosity during the fermentation process, achieve the characteristics of good compatibility, and achieve sufficient Fusion, then air-dried until there is no moisture on the surface, and carbonization operation;

[0029] Step 3: Fermentation: the air-dried straw is fermented at 28°C, t...

Embodiment 2

[0035] It contains the following raw materials by weight: 70% of straw, 8% of cellulose-degrading bacteria, 6% of ammonia nitrogen-degrading bacteria, 8% of sulfur-fixing agent, and 8% of polyethylene wax. By adding 8% of cellulose-degrading bacteria, the soil can be decomposed Fungal action, and the added value is the same as that of sulfur fixer and polyethylene wax, which achieves the advantages of viscosity and controlled removal of sulfur oxides. Secondly, ammonia nitrogen degrading bacteria can quickly oxidize ammonia nitrogen into nitrite nitrogen and then into nitrate nitrogen, increasing the nitrification efficiency. , and the role of the sulfur-fixing agent is to control the soil of the dye and remove sulfur oxides, and at the same time, the polyethylene wax can improve the viscosity during the fermentation process, achieve the characteristics of better compatibility, and achieve full fusion.

Embodiment 3

[0037] Raw materials containing the following weight percentages: 70% of straw, 10% of cellulose degrading bacteria, 8% of ammonia nitrogen degrading bacteria, 7% of sulfur-fixing agent, and 5% of polyethylene wax. The straw can be: rice husk, corn cobs, fruit tree pruning etc., or compressing and granulating materials such as wood chips, coconut shells, and hay into pellet fuels, all of which can be used for direct combustion and carbonization. During the cleaning process, the straw is removed to remove impurities, so that the straw and fungi are soaked and fused. , after fusion, it can degrade fungi and oxidize nitrate nitrogen, etc., and at the same time, decomposing agent can be added to cooperate with urea to achieve fertilization effect, which is beneficial to soil phosphorus activity conditioning. Soil phosphorus content of biochar-based soil phosphorus active conditioners.

Abstract

The invention provides a straw biochar-based soil phosphorus active conditioner and a preparation method thereof, and relates to the technical field of agricultural preparation. Comprising the following raw materials in percentage by weight: 60-80% of straws, 5-10% of cellulose degrading bacteria, 5-10% of ammonia nitrogen degrading bacteria, 5-10% of a sulfur-fixing agent and 3-8% of polyethylene wax. The preparation method comprises the following steps: step 1, taking crop straws, and cutting the crop straws into 3-5cm by using cutting equipment; step 2, cleaning and filtering: cleaning the straws, and soaking the cleaned straws in water; step 3, fermentation: fermenting the air-dried straws; 4, carbonization is conducted, specifically, the cut straw is placed in a carbonization furnace to be subjected to carbonization operation; step 5, cooling: cooling the carbonized straws; step 6, crushing: crushing the carbonized straws; and 7, storage: performing temperature-controlled storage on the carbonized straws through a sealing bin.

Description

technical field [0001] The invention relates to the technical field of agricultural preparation, in particular to a straw biochar-based soil phosphorus active conditioner and a preparation method thereof. Background technique [0002] Straw biochar refers to the solid product after high temperature thermal cracking of organic matter in incomplete combustion or anoxic environment. The charred plant stubble that has not been burnt out after the forest fire is the biochar made in nature; and artificial charcoal is too numerous to mention, such as charcoal, bamboo charcoal, rice husk charcoal, etc. The entire high-temperature thermal cracking process is the so-called "carbonization" or "dry distillation", in addition to producing solid carbon, it also produces liquid and gas. Carbon monoxide and other flammable gases; [0003] Soil phosphorus active conditioner is composed of agricultural water-retaining agent and natural peat or other organic matter rich in organic matter and...
