Green alga and viable bacterium compound, method for preparing same and application of green alga and viable bacterium compound

Abstract

The invention discloses a green alga and viable bacterium compound, a method for preparing the same and application of the green alga and viable bacterium compound. The green alga and viable bacteriumcompound comprises, by weight, 40-60 parts of green algae and 10-20 parts of viable bacteria. The green algae are chlorella, and the viable bacteria are photosynthetic bacteria and bacillus polymyxa.The green alga and viable bacterium compound, the method and the application have the advantages that the green alga and viable bacterium compound can be used in the agricultural field; the bacteriaand the algae are complementary with one another, and accordingly the green alga and viable bacterium compound is environmentally friendly; effects of promoting growth of crops, improving the diseaseresistance of the crops, increasing the yield of the crops and improving the quality of the crops can be realized; the green alga and viable bacterium compound can be used as a foliar fertilizer, accordingly, the photosynthetic rates of the crops can be increased by 2-3 times, nitrogen sources and carbon dioxide in air can be sufficiently utilized, energy can be saved, and environments can be protected; effects of remedying soil further can be realized by the green alga and viable bacterium compound, and effects of immobilizing heavy metal, degrading harmful substances such as polycyclic aromatic hydrocarbons, reducing the salt concentration and improving the water retention and fertilizer conservation capacity of the soil can be realized by the green alga and viable bacterium compound.

Description

technical field [0001] The invention relates to the field of agricultural technology, in particular to a green algae live bacteria compound and its preparation method and application. Background technique [0002] Chlorella is a member of the plant kingdom Chlorophyta, with about 6,700 species. It is mainly distributed in fresh water, but also in seawater and wet places on land. The ratio of photosynthetic pigments (chlorophyll a and b, carotene, lutein) in green algae is similar to that of seed plants and other higher plants. Typical green algae cells may or may not be motile. It has a central vacuole, the pigment is in the plastid, and the shape of the plastid varies from species to species. The cell wall consists of two layers of cellulose and pectin. Food is stored in the protein nucleus in the plastid in the form of starch. [0003] Photosynthetic bacteria (PSB for short) are the earliest prokaryotic organisms with a primitive photosynthetic system on the earth, an...
