Embodiment 1

[0029]Firstly prepare the compound bacterial agent, respectively ferment Bacillus subtilis, Bacillus megaterium, and phosphate solubilizing bacteria in industrial fermentation tanks, and obtain the fermented liquid according to the weight ratio of Bacillus phleus, Bacillus megaterium, and phosphate solubilizing bacteria in a ratio of 2:1:2 Compounded and concentrated at 25°C to obtain a complex microbial agent. Mix 150kg of bamboo charcoal, 180kg of peat and 210kg of coconut shell activated carbon and then air-dry them. After air-drying, make 0.2mm powder and add 300kg of HNO at room temperature 3 solution and 450kgH 2 o 2 The solution is oxidized, and after treatment, water is added in a certain proportion to obtain the mixed material A. Then 54kg of humus and 110kg of vermicompost were pulverized, and then 28kg of bamboo vinegar and water were added in proportion, so that the water content of the raw material was controlled between 35%, and piled up and fermented for 5 day...

Embodiment 2

[0031] Bacillus subtilis and phosphate solubilizing bacteria are fermented separately in industrial fermentation tanks, and the fermented liquid obtained is compounded according to the weight ratio of Bacillus phleus and phosphate solubilizing bacteria at a ratio of 2:1, and concentrated at 25°C to obtain a composite bacterial agent. Mix 162kg of bamboo charcoal, 195kg of peat and 230kg of coconut shell activated carbon and then air-dry them. After air-drying, make 0.3mm powder and add 400kg of HNO at room temperature 3 solution and 500kgH 2 o 2 The solution is oxidized, and after treatment, water is added in a certain proportion to obtain the mixed material A. Then 56kg of humus and 110kg of vermicompost were pulverized, and then 32kg of bamboo vinegar and water were added in proportion, so that the water content of the raw material was controlled between 45%, and piled up and fermented for 7 days under the condition of 28°C-32°C to obtain The first fermentation product; th...

Embodiment 3

[0033] Bacillus megaterium and phosphate solubilizing bacteria are fermented separately in industrial fermentation tanks, and the obtained fermentation broth is compounded according to the weight ratio of Bacillus megaterium and phosphate solubilizing bacteria at a ratio of 3:1, and then concentrated at 25°C to obtain a composite bacterial agent. 170kg of bamboo charcoal, 190kg of peat and 235kg of coconut shell activated carbon were mixed and then air-dried. After air-drying, 0.4mm powder was made, and 480kg of HNO was added at room temperature. 3 solution and 480kgH 2 o 2 The solution is oxidized, and after treatment, water is added in a certain proportion to obtain the mixed material A. Then 57kg of leaf humus and 115kg of vermicompost were pulverized, and then 30kg of bamboo vinegar and water were added in proportion to make the water content of the raw materials controlled between 35%, and piled up and fermented for 10 days under the condition of 29°C to obtain the first...

Abstract

The invention discloses a soil nutrient activator suitable for saline-alkali land improvement and a preparation method thereof. It uses a variety of natural charcoal and organic matter as main raw materials to provide a green and pollution-free soil nutrient activator rich in stable organic carbon. Compared with traditional soil improvers, the soil nutrient activator can effectively activate the soil structure, and the pH value of the improved soil is reduced from 9.15 to 6.95. The soil nutrient activator can effectively improve the soil structure, adjust the soil pH, and improve the soil air permeability , water retention, and at the same time promote the growth of watermelon plants, improve the internal and external quality of watermelons, and have extensive practicability in the technical field of saline-alkali land improvement.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizer processing. Specifically, the invention relates to a soil nutrient activator and the technical field of preparation thereof. Background technique [0002] Saline-alkali soil is widely distributed in my country, with a total area of ​​36.67 million hectares, ranking fourth in the world, of which nearly 6.7 million hectares of saline-alkali cultivated land accounts for about 5% of the country's cultivated land. Saline-alkali soil, also known as saline soil, includes two types of soil with different properties: saline soil and alkaline soil. When the soluble salts in the soil surface exceed 0.1%, it is saline soil, and when the total salt content exceeds 1%, it is called saline soil. When the soil surface contains more sodium carbonate, the soil will be strongly alkaline. When the exchangeable sodium ion accounts for more than 5% of the cation exchange capacity, it is called alkaline...
