Embodiment 1

[0026] Example 1 Preparation of tobacco water-retaining bio-organic fertilizer.

[0027] (1) Bacteria production

[0028] 1) Inoculate Bacillus.amyloliquefaciens IAE into liquid seed medium for cultivation. The cultivation conditions are as follows: cultivation temperature 37°C, shaker rotation speed 130-160rpm, cultivation time 24 hours, seed bacteria content greater than 1×10 9 cfu ml -1 , the seeds are inoculated into the fermenter according to the volume ratio of 5% for liquid fermentation production. The conditions for the fermentation production are: the culture temperature is 28-35°C, the dissolved oxygen ventilation range is 30-100%, 120-160rpm, and some strains are formed in the later stage of fermentation Bacillus, the colony forming unit of the strain in the fermentation broth ≥ 1×10 9 cfu ml -1 , the concentration of the fermentation broth became thicker; the formula of the liquid seed medium used was prepared according to 1L medium: beef extract 3g, peptone 10g...

Abstract

The invention discloses a tobacco water retention biological organic fertilizer and a preparation method thereof. The preparation method comprises the following steps: fermenting wastes by using bacillus amyloliquefaciens (IAE), compounding the fermentation product with humic acid, and then secondarily fermenting vinegar residue compost to from a biological organic fertilizer which is suitable for tobaccos and has a water retention effect. In the biological organic fertilizer, the number of effective strains is more than or equal to 0.5*10<8>cfu / g, the content of an effective water retention material is more than or equal to 21g / kg in dry weight, the water content is less than or equal to 30%, and the organic content is more than or equal to 45%. A test shows that after the tobacco is transplanted for 30 days, the water content of 0-10cm of the tobacco field soil in which the biological organic fertilizer is applied is 32.7% higher than that of the soil in which the biological organic fertilizer is not applied and the tobacco plant biomass is increased by 55.6%. The water retention biological organic fertilizer disclosed by the invention can significantly increase the water content of the soil and improve the biomass of tobacco plants at the seedling stage.

Description

technical field [0001] The invention belongs to the technical field of water and soil conservation, and relates to a tobacco water-retaining bio-organic fertilizer and a preparation method thereof. Background technique [0002] my country is the country with the largest tobacco cultivation area in the world, and some provinces have millions of acres of tobacco cultivation area. Tobacco income is an important source of local farmers' family income. The planting time of tobacco in some areas is from February to May every year, which is a period of time with less precipitation in a year. The planted tobacco needs to be watered manually, which consumes a lot of manpower. [0003] Water-retaining fertilizer is a kind of fertilizer containing water-retaining substances, and most of the water-retaining substances added to water-retaining fertilizers are polyacrylamide substances or humic acid substances. Some chemical substances are likely to cause soil compaction and plant root r...
