Embodiment 1

[0026] Example 1 Preparation of organic fertilizer for tobacco

[0027] Grind 1000kg oil dry with a pulverizer, with a fineness of 1mm~3mm, and then transport the fine oil dry with a vehicle into the mixer, and add 25kg CaCO 3 Adjust the pH to 6.5, add 480 kg of water while stirring, and add 0.5 kg of fermentation base to make the water content of the oil dry up to 60%.

[0028] The fermentation tank is a brick tank with a length of 30 meters, a width of 9 meters, and a height of 1.1 meters. It is divided into 6 parts. A track is installed on the fermentation tank, and a mechanical turning and polishing machine is installed on the track. Use a belt conveyor to transport the above-prepared oil dry into the first unit fermentation tank, and load it into 33.33 cubic meters. The cloth material is 5 meters long, 1.0 meters high and 9 meters wide. After 24 hours, start the mechanical turning and throwing machine, and push forward 5 meters of the raw materials placed on the first day, tha...

Embodiment 3

[0049] Example 3 Determination of fertilizer efficiency of organic fertilizer

[0050] The organic fertilizer prepared in Example 1 was tested in the field of flue-cured tobacco plants, and the dosage was set at three levels, level 1 was 10kg / mu, level 2 was 20kg / mu, and level 3 was 30kg / mu. The control sample was inorganic fertilizer (N%, P 2 O 5 %, K 2 The O% weight content is 9%, 9%, and 27% respectively), and the flue-cured tobacco plants are applied with base fertilizer before transplanting.

[0051] Table 3 Effects of applying different dosages of oil kuh on the economic properties of tobacco leaves

[0052]

[0053] *The price is the national price standard for purchasing flue-cured tobacco.

[0054]

[0055] From Tables 3 and 4, it can be seen that the organic fertilizer prepared in Example 1 has a higher output value than the control sample. After application, the tobacco plant grows vigorously and the leaves are well developed. After curing, the color of the tobacco leaves i...

Abstract

The invention belongs to the technical field of organic fertilizers, and particularly relates to organic fertilizer for tobacco and a preparation method thereof. The organic fertilizer for the tobacco is prepared from an oil cake and a fermentation base which are mixed evenly according to the weight ratio of between 1 and 0.0004 to 0.0006 and are fermented; compositions of the fermentation base are beneficial microbial inoculum and effective vectors of high, medium and low temperature aerobic fermentation, and the number of live bacteria is between 4 and 20 hundred millions / g. The preparationmethod comprises the following steps: the oil cake is crushed to a fineness of between 1 and 3 mm, CaCO3 is added to adjust the pH value to be between 6 and 7, the fermentation base which accounts for 0.0004 and 0.0006 of the weight of the oil cake and water which accounts for 0.4 to 0.6 of the weight of the oil cake are added to stir evenly, and the organic fertilizer can be obtained through thedrying after the fermentation. The organic fertilizer can kill harmful bacteria, parasitic ova and weed seeds, a tobacco plant has robust growth and well-developed leaves after the application, the proportion of first-class tobacco and orange tobacco is greatly improved, tobacco leaves after the roasting have bright and glossy color and luster, and chemical compositions of crude tobacco are harmonious.

Description

Technical field [0001] The invention relates to an organic fertilizer and a preparation method and application thereof, and belongs to the technical field of organic fertilizers. Background technique [0002] Neglect of organic fertilizers in farmland and long-term application of inorganic fertilizers will cause soil compaction, decrease of organic matter content, uncoordinated nutrient supply, adjustment of soil physical and chemical properties and decrease of soil biological self-repair ability. At the same time, the burning of a large amount of crop straw not only wastes good biological resources, but also seriously pollutes the environment. [0003] The agricultural sector currently attaches great importance to the application of farmyard manure, and vigorously promotes planting green manure, returning to the field through the belly, returning straw to the field, and returning manure to the field to improve soil. However, the use of traditional organic fertilizers that have no...
