Embodiment Construction

[0026] 1. The provision of algae mud

[0027] It is provided free of charge by salvage stations around Taihu Lake and placed in the algae mud storage pool for 2 months.

[0028] 2. Production of functional bacterial agent

[0029] The growth-promoting bacteria SQR9 was inoculated into the PDA culture medium for liquid fermentation production. The conditions for fermentation production were: natural pH growth range, culture temperature range of 30-35°C, stirring speed of 180-300 rpm, and formation of Spores, so that the number of bacteria or spores in the fermentation broth is ≥1×10 9pieces / ml. The preparation method of the PDA culture medium used is as follows, taking the preparation of 1L medium as an example: Peel 200g of potatoes, cut into small pieces, put them in water and boil, boil for 30min, add 20g of ordinary sucrose to the filtrate after filtration, and dilute to 1000ml, adjust the pH value to 7.0-7.6, and sterilize at 121°C for 20min.

Abstract

The invention provides a low-cost growth promoting bioorganic fertilizer produced by using algae mud as an additive and a production technology thereof, and belongs to an agricultural intensive production technology. A formula consists of 95 weight percent of common decomposed cow dung fertilizer and 5 weight percent of dry algae mud; the strain is growth promoting bacillus amyloliquefaciens SQR-9; and the technology comprises the following process flow of: mixing the raw materials according to an optimal formula, inoculating 5 percent of growth promoting bacteria, performing strip stacking fermentation, turning once every day, and fermenting for 6 to 7 days. The beneficial viable count of the produced fertilizer is more than 2*10<7> CFU/g (dry fertilizer weight), the total nitrogen content is 1.2 to 2.0 percent, the total nitrogen, phosphorus and potassium nutrient is more than or equal to 5 percent, the organic substance content exceeds 45 percent, and both the content of microcystin LR and the content of the microcystin RR are less than 4mug/kg. The bioorganic fertilizer is rich in amino acid, low in production cost and good in growth promoting effect, and can be applied to food crops, vegetables and the like.

Description

1. Technical field [0001] The invention provides a process and product for producing growth-promoting bio-organic fertilizer using algae mud as an additive, which belongs to the intensive agricultural production technology. grow. 2. Background technology [0002] In recent years, cyanobacteria blooms have occurred in major lakes at home and abroad, and the eutrophication of lakes has attracted increasing attention. Every summer and autumn, major lakes such as Chaohu Lake, Dianchi Lake, Taihu Lake, and Donghu Lake in my country frequently break out algal blooms due to serious water eutrophication, which brings serious water crisis to urban residents. There are many ways to remove cyanobacteria, directly remove cyanobacteria in the water body, and remove the water body, that is, the salvage method of cyanobacteria, which is currently a very effective and uncontroversial method in the academic circle. Due to the high water content of cyanobacteria, which reaches 98%, and occu...
