Problems solved by technology

[0006] Studies have shown that the use of Zanthoxylum bungeanum as a biological fumigant has a good killing effect on root-knot nematodes, but the research on using it as a biocontrol bacterial fermentation material and soil-borne disease inhibitor has not been reported, and Zanthoxylum bungeanum has a Acidity, different soils and plant growth have different pH requirements, and most existing fertilizers cannot be adjusted in a timely manner according to the situation

Embodiment 1

[0045] The preparation of the combined acid-base regulating Zanthoxylum bungeanum biocontrol bacterial fertilizer of the present invention comprises the steps of:

[0046](1) Preparation of raw materials for part A: Take 17 parts by mass of Zanthoxylum bungeanum seeds and 5 parts by mass of cassava, crush them and mix them uniformly, and then add 0.07 parts by mass of Bacillus subtilis bacterial liquid, 33 parts by mass of water, fermented at 28°C for 7 days;

[0047] Among them, the Bacillus subtilis bacterial liquid is preferably Bacillus subtilis Tpb55, which is isolated and preserved by the Tobacco Research Institute of the Chinese Academy of Agricultural Sciences, activated and cultivated with LB (Luria-Bertani) medium, and resuspended to OD=0.5 with sterile water for later use.

[0048] (2) Preparation of raw materials for part B: take rice husks as raw materials and prepare them by anaerobic pyrolysis at 400°C, control the air-dried moisture content (MAD) of biomass cha...

Embodiment 2

[0055] (1) Preparation of raw materials for part A: Take 16 parts by mass of Zanthoxylum bungeanum seeds and 1.7 parts by mass of cassava, grind them and mix them evenly, and then add 0.05 parts by mass of Bacillus subtilis bacterial liquid, 33 parts by mass of water, fermented at 28°C for 7 days;

[0056] (3) Forming part A and part B: put the raw materials of part A and 45 parts by mass of the raw materials of part B into a fertilizer molding machine and press them into rods respectively to obtain part A and part B;

[0057] Other steps are the same.

Embodiment 3

[0059] (1) Preparation of raw materials for part A: Take 20 parts by mass of Zanthoxylum bungeanum seeds and 3.5 parts by mass of cassava, grind them and mix them evenly, and then add 0.08 parts by mass of Bacillus subtilis bacterial liquid, 33 parts by mass of water, fermented at 28°C for 7 days;

[0060] (3) Forming part A and part B: put the raw materials of part A and 25 parts by mass of the raw materials of part B into a fertilizer forming machine and press them into rods respectively to obtain part A and part B;

[0061] Other steps are the same.

Abstract

The invention discloses a combined acid-alkali adjusting zanthoxylum bungeanum maxim seed biocontrol bacterial fertilizer, which comprises a part A and a part B, wherein the part A and the part B areboth in a rod shape, the multiple parts A are arranged around the part B in a surrounding mode, the part A comprises 16-24 parts by mass of zanthoxylum bungeanum maxim seeds, 1.5-5 parts by mass of cassava and 0.05-0.1 part by mass of a bacillus subtilis liquid, and the part B comprises 15-45 parts by mass of biomass charcoal. The invention discloses prevention and control for tobacco black shank,wherein a plant antibacterial material zanthoxylum bungeanum maxim seeds, cassava and biomass charcoal are combined, and fermentation is performed by using a bacillus subtilis biocontrol strain to obtain a biocontrol bacterial fertilizer, so that the obtained biocontrol bacterial fertilizer has good inhibiting effect on phytophthora nicotianae, can improve the physical and chemical properties ofsoil, can adjust the proportion of beneficial microorganisms in rhizosphere soil, and can completely replace chemical pesticides and chemical fertilizers.

Description

technical field [0001] The invention relates to the field of agricultural fertilizers, in particular to a combined acid-base regulating prickly ash seed bio-control bacterial fertilizer and a preparation method thereof. Background technique [0002] Tobacco black shank is a serious oomycete soil-borne disease caused by Phytophthora nicotianae. In my country, the epidemic area of ​​the disease exceeds 76372hm 2 , the annual direct economic loss caused is more than 800 million yuan, and it is one of the main devastating diseases of tobacco in China and even in the world. The existing control of tobacco black shank is mainly based on amide pesticides such as metalaxyl and dimethomorph, which has caused a series of problems such as high pesticide residues in tobacco leaves, environmental pollution and serious drug resistance, and long-term partial application of chemical fertilizers, It causes soil compaction, decline of organic matter, and imbalance of beneficial microorganis...
