Problems solved by technology

[0002] Saline-alkali land refers to the general name of various types of soils that contain too much saline-alkali components in the soil, including saline soil and alkaline soil, and other types of soil that have undergone a certain degree of salinization or alkalization. Saline soil refers to a large amount of soluble salts that make most plants Soil that cannot grow. Alkaline soil refers to the soil where the percentage of substitutable sodium ions accounts for more than 20% of the cation replacement capacity and the pH value exceeds 8. In fact, because saline soil and alkaline soil are often interlaced, it is customary to collectively call them saline-alkali soil. , saline-alkali land is more harmful, mainly manifested in restricting agricultural production, destroying the ecological environment and affecting sustainable d

Embodiment 1

[0015] 1) Cut 15 parts of rice stalks to a length of 6 cm, then crush 6 parts of peanut shells into peanut shell powder, soak the cut rice stalks and peanut shell powder in distilled water for 2.5 hours;

[0016] 2) Add the preparation in step 1), 10 parts of sulfur and 3 parts of kaolin to 42 parts of fresh chicken manure and mix evenly, and then spray 0.021 parts of microbial agent into the mixture;

[0017] 3) Add the mixture in step 2) to the reactor, stir at a speed of 30r / min, and at the same time pass cooling water into the jacket of the reactor, and control the reaction temperature to remain at 65°C. As the reaction time increases, the reaction temperature gradually increases. Decrease, at this moment, stop passing cooling water in the jacket of the reaction kettle, change to pass water vapor, continue to keep the reaction temperature at 65°C, and the total reaction time is 65min.

Embodiment 2

[0019] 1) Cut 16 parts of rice stalks to a length of 6 cm, then crush 7 parts of peanut shells into peanut shell powder, soak the cut rice stalks and peanut shell powder in distilled water for 2.6 hours;

[0020] 2) Add the preparation in step 1), 12 parts of sulfur and 4 parts of kaolin to 45 parts of fresh chicken manure and mix evenly, and then spray 0.023 parts of microbial agent into the mixture;

[0021] 3) Add the mixture in step 2) to the reactor, stir at a speed of 30r / min, and at the same time pass cooling water into the jacket of the reactor, and control the reaction temperature to remain at 67°C. As the reaction time increases, the reaction temperature gradually increases. Decrease, at this moment, stop passing cooling water in the jacket of the reaction kettle, change to pass water vapor, continue to keep the reaction temperature at 67°C, and the total reaction time is 62min.

Embodiment 3

[0023] 1) Cut 17 parts of rice stalks to a length of 6 cm, then crush 8 parts of peanut shells into peanut shell powder, soak the cut rice stalks and peanut shell powder in distilled water for 2.7 hours;

[0024] 2) Add the preparation in step 1), 14 parts of sulfur and 5 parts of kaolin to 48 parts of fresh chicken manure and mix evenly, and then spray 0.024 parts of microbial agent into the mixture;

[0025] 3) Add the mixture in step 2) to the reactor, stir at a speed of 30r / min, and at the same time pass cooling water into the jacket of the reactor, and control the reaction temperature to remain at 69°C. As the reaction time increases, the reaction temperature gradually increases. Decrease, at this moment, stop passing cooling water in the jacket of the reaction kettle, change to pass water vapor, continue to keep the reaction temperature at 69°C, and the total reaction time is 59min.

Abstract

The invention discloses the technical field of saline-alkali soil improvement, and particularly discloses the field of a saline-alkali soil chicken manure fermented fertilizer. The saline-alkali soilchicken manure fermented fertilizer comprises the raw materials with corresponding weight parts: 42-55 parts of fresh chicken manure, 15-18 parts of rice straw, 10-16 parts of sulfur, 6-10 parts of peanut shells, 3-6 parts of kaoline, and 0.021-0.028 part of a microbial agent. Sulfur after heating can be combined with oxygen to generate sulfur dioxide; the sulfur dioxide is dissolved in water to generate sulfurous acid or is oxidized to generate sulfuric acid under the action of bacteria; sulfurous acid or sulfuric acid can react with ammonia in a mixed fermentation substance to generate ammonium sulfate, so the content of effective nitrogen in the chicken manure fermented fertilizer is increased, and at the same time, the emission of ammonia gas is reduced; the kaoline has a dispersing effect, the content of colloids in chicken manure is high, the kaoline can improve the dispersion uniformity of the chicken manure fermented fertilizer, and the occurrence of partial condensation or caking phenomenon of the chicken manure fermented fertilizer is prevented.
