Microalgae nutrient solution, fertilizer composition and sugar beet fertilizing method

Resumen de: CN119662412A

The invention provides a microalgae nutrient solution and application thereof, and belongs to the technical field of agriculture. The invention provides a microalgae nutrient solution. The microalgae nutrient solution comprises nitrogen-fixing blue-green algae and photosynthetic nutrient green algae, the content of algae single cells in the microalgae nutrient solution is greater than or equal to 1.0 * 10 < 6 >. The microalgae nutrient solution provided by the invention, as a microalgae fertilizer, can significantly improve the activities of urease, sucrase and catalase in soil and reduce the activity of polyphenol oxidase in the soil; the content of alkali-hydrolyzable nitrogen in soil is increased, and the nitrogen fertilizer absorption amount of beet is improved; the richness of soil microbial communities can be increased, and the number of actinomycetes and proteobacteria is increased; growth and development of the beet can be remarkably promoted, the plant height, fresh weight, leaf number, chlorophyll content and net photosynthetic rate of the beet can be improved, accumulation of dry matter of beet tuberous roots can be promoted, timely transfer of beet growth centers can be regulated, and then the yield and sugar yield of the beet can be increased.

Resumen de: CN222647926U

The utility model discloses a microalgae culture shelf which comprises four stand columns, three placing plates are welded among the four stand columns from top to bottom at equal intervals, and a lifting adjusting mechanism is installed in the middle of the upper end of each placing plate. The microalgae culture frame has the beneficial effects that the lifting adjusting mechanism is mounted on the placing plate, so that the bidirectional screw rod can be rotated by virtue of a hand wheel in the lifting adjusting mechanism when the microalgae culture frame is used, and the lifting plate can be lifted under the action of the bidirectional screw rod and a connecting rod; by means of the design, when the microalgae culture shelf is used, step-shaped height differences can be formed between the microalgae culture bottles on the inner sides of all the layers of containing plates and the microalgae culture bottles on the edges, it is guaranteed that illumination intensity borne by microalgae in all the rows of microalgae culture bottles is uniform, and meanwhile workers can conveniently observe the growth conditions of all the rows of microalgae conveniently.
