Problems solved by technology

Compared with chemical fertilizers, the application of these products has played a positive role in the protection of the ecological environment, but these microbial fertilizers are often powerless for the bioremediation of soil pollution, especially heavy metal pollution
[0003] And the arbuscular mycorrhizal mycorrhizal agents that appear in recent years are also mostly concentrated on several aspects such as improving the mineral nutrition of plants, improving drought resistance, and promoting the growth of plants, as disclosed in the description of No. 00137712.4 of Chinese patent. Phosphorus-functional arbuscular mycorrhizal agents and their production methods, but no patents or products on improving plant heavy metal resistance

Embodiment Construction

[0022] Pass the river sand and peat through a 1mm sieve, mix according to the volume of 1:1, and mix in a certain amount of urea (0.078 g / kg matrix) and superphosphate (0.33 g / kg matrix), weigh it and put it into a plastic box. The species containing Glomus caledonium, Gigaspora margarita, Gigaspora decipens, Scutellospora gilmori and Asapora ( Acaulospora) and various arbuscular mycorrhizal fungi of the genus Glomus (Glomus) soil samples were used as inoculum, and the inoculum amount was 3%-5%. Mix it into the matrix, pour about 20% of water, and sow sudan grass. Routine management, after 3 months, check whether the spore density of arbuscular mycorrhizae in the soil is > 10 per gram of dry soil. After reaching the standard, cut off the upper part of the Sudan grass, cut the root into pieces, mix it with the substrate, and let it dry in the air use.

Abstract

A microbial prararation for increasing the absorptivity of plant to copper contains more useful microbes including scotch blastocyst, panicillium sp., etc. It is prepared by culturing them in liquid-state Ca's culture medium.

Description

technical field [0001] The invention relates to a high-efficiency microbial bacterial agent and a preparation method thereof, in particular to a microbial bacterial agent capable of improving plant copper absorption and a preparation method thereof. Background technique [0002] At present, the known public microbial fertilizers are mostly composed of nitrogen-fixing bacteria, phosphorus bacteria, potassium bacteria, photosynthetic bacteria, bacillus, silicate bacteria and other bacteria, which can improve the yield and quality of plants by improving the nutritional status of plants. Compared with chemical fertilizers, the application of these products has played a positive role in the protection of the ecological environment, but these microbial fertilizers are often powerless for the bioremediation of soil pollution, especially heavy metal pollution. [0003] And the arbuscular mycorrhizal mycorrhizal agents that appear in recent years are also mostly concentrated on sever...
