Embodiment 1

[0020] Production of tobacco biotype coated pelleted seeds. Synchronous plate confrontation method, seed germination method and greenhouse potting method are used to screen the rhizosphere bacteria that antagonize Pythium melons and fruits and promote plant growth; further use synchronous confrontation method and bacterial suspension biological treatment method to screen the main mildew microorganisms. The antagonistic bacteria in the rhizosphere are the screened active bacteria.

[0021] A. Screening of Tobacco Damping-off Antagonistic Bacteria

[0022] 1. Process:

[0023] 1.1 Isolation and purification of antagonistic rhizosphere bacteria

[0024] Collect rhizosphere soil samples of healthy plants in diseased fields with serious root diseases, and use dilution coating method to separate and purify on NA plate.

[0025] 1.2 Antagonism detection

[0026] 1.2.1 Determination of antagonistic activity

[0027] The isolated rhizobacteria are planted around the PDA plate with...

Embodiment 2

[0082] Preparation of seed coating

[0083] The parts by weight of the seed coating raw material are special mineral clay 30, talcum powder 66, 0.5 of 90% Wanling raw powder, and tobacco compound fertilizer 3.5; half of the talcum powder is added in the mixer, and then special mineral clay, 90% The original powder of all spirits and tobacco compound fertilizer, and finally add the remaining talcum powder into the mixer; start the machine, mix for 15 to 25 minutes, stop the machine, and obtain the seed coating agent.

Embodiment 3

[0085] Nutrient solution prepared with active bacteria as solvent

[0086] The preparation of nutrient solution can be as shown in table 4.

Abstract

The present invention discloses one production process of biologically coated tobacco seed. The production process includes the esparation and screening of biologically coating active bacteria; the preparation of original active bacteria liquid; and biologically coating seed. Original active bacteria liquid or concentrated original active bacteria liquid, rather than aquatic nutritive liquid, is used in preparing seed balls. The said method of producing biologically coated tobacc seed can prevent sotto disease of tobacco in germination and seedling stage, antagonize tobacco mosaic disease germ as main mildew microlbe of tobacco, and promote the germination of tobacco seed and the growth of tobacco seedling.

Description

technical field [0001] The present invention relates to the production method of tobacco seed, more particularly, the present invention relates to a kind of method of utilizing modern biotechnology to process tobacco coated seed. Background technique [0002] The main mildew fungus of tobacco seeds is Alternaria alternata. On the one hand, it causes seed mildew, and on the other hand, it is the source of primary infection of tobacco red spot. If the bio-coated active bacteria can antagonize Alternaria Alternaria, it can reduce the amount of Alternaria Alternaria, effectively control seed mildew, and may reduce the harm of Alternaria Alternaria in the mature stage. [0003] Tobacco damping-off is one of the main soil-borne diseases of tobacco seedlings, and its pathogen is mainly Pythium. There are as many as 4 species of Pythium that cause damping-off in Yunnan, among which Pythium aphanidermatum is the dominant species and the species most pathogen...
