Embodiment 1

[0031] The microalgae fertilizer is obtained by adding the Haematococcus pluvialis culture liquid to the water-soluble fertilizer; the mass ratio of the Haematococcus pluvialls culture liquid to the water-soluble fertilizer is 5:95.

Embodiment 2

[0033] The microalgae fertilizer is obtained by adding the Haematococcus pluvialis culture liquid to the water-soluble fertilizer; the mass ratio of the Haematococcus pluvialls culture liquid to the water-soluble fertilizer is 5:95.

[0034] The Haematococcus pluvialis culture solution is carried out according to the following steps: inoculate the Haematococcus pluvialls into the culture medium, place it in a closed photobioreactor, and cultivate it to obtain the Haematococcus pluvialls culture solution in the swimming growth stage;

[0035] The culture medium is BG11;

[0036] The culture conditions were as follows: culture temperature 20°C; light intensity 80 μmol / (m2·s); carbon dioxide concentration 6%; culture time 7 days.

Embodiment 3

[0038] The microalgae fertilizer is obtained by adding Haematococcus pluvialis into the water-soluble fertilizer; the mass ratio of Haematococcus pluvialis to the water-soluble fertilizer is 5:95.

[0039] The Haematococcus Pluvialls culture solution is carried out according to the following steps: Inoculate the Haematococcus Pluvialls into the culture medium, place it in a closed photobioreactor, and cultivate it to obtain the Haematococcus Pluvialls culture solution in the swimming growth stage, The medium contains adenosine triphosphate; the culture conditions are culture temperature 20°C; light intensity 80 μmol / (m2·s); carbon dioxide concentration 6%; culture for 7 days.

[0040] The medium is BG11; the mass ratio of the medium to adenosine triphosphate is 999.99:0.01.

Abstract

The invention relates to a microalgae fertilizer and a preparation method thereof. The microalgae fertilizer consists of microalgae and a fertilizer. The preparation method of the microalgae fertilizer comprises: adding the microalgae into the fertilizer to obtain the microalgae fertilizer. By adopting the microalgae fertilizer, sugar content in crop root systems can be improved, so that stress resistance of crops is improved; meanwhile, by the microalgae fertilizer, crop quality can also be improved.

Description

technical field [0001] The invention relates to a microalgae fertilizer and a preparation method thereof. Background technique [0002] Haematococcus pluvialis is recognized as the best organism in nature to produce natural astaxanthin, therefore, using this microalgae The extraction of astaxanthin undoubtedly has broad development prospects, and has become a research hotspot in the production of natural astaxanthin in the world. [0003] Haematococcus pluvialis mainly grows and distributes in small ponds and small temporary blisters formed by accumulated water after rain in nature. It is the microorganism that synthesizes and accumulates the most astaxanthin in nature. Haematococcus pluvialis has strong adaptability to the environment: under suitable growth conditions, it grows and reproduces rapidly with flagellar swimming cells; The cell loses its flagella, its walls thicken, and it accumulates a large amount of red substance, causing the cell to enter a dormant state. ...
