Embodiment 1

[0036] Such as figure 1 Shown, the preparation method of microbial activity tobacco seedling culture substrate comprises the following steps:

[0037] Description of raw materials, EM bacteria freeze-dried powder, peat, vermiculite, perlite, brown sugar, salt, urea, rapeseed cake, rice bran, wheat bran, superphosphate and biochar can all be selected from common commercial products, rapeseed The fresher the cake, rice bran and wheat bran, the better; the humus soil should be taken from unpolluted mountain forests with well-preserved ecological vegetation, aired in the shade until semi-dry, and crushed into fine particles no larger than the size of soybeans.

[0038] 1) Activation of EM bacteria: for the first round of activation of EM bacteria, add 500ml of water, 50g of brown sugar, 1.5g of table salt, and 2.5g of urea into a 500ml Erlenmeyer flask, dissolve and bandage, sterilize at 115°C for 20 minutes, take it out, and cool to room temperature. Insert 5g of preserved EM ba...

Embodiment 2

[0043] A preparation method for microbially active tobacco seedling-growing matrix, comprising the following steps:

[0044] 1) Activation of EM bacteria: For the first round of activation of EM bacteria, add 500ml of water, 40g of brown sugar, 2.5g of salt, and 1.5g of urea into a 500ml Erlenmeyer flask, dissolve and wrap, sterilize at 115°C for 20 minutes, take it out, and cool to room temperature. Insert 2.6g of preserved freeze-dried powder of EM bacteria, and culture at 35°C for 24 hours; for the second round of activation of EM bacteria, add 12L of water, 800g of brown sugar, 10g of salt, and 80g of urea to the serum bottle, dissolve, seal, and sterilize at 115°C for 20 Minutes, take it out, cool to room temperature, insert 32ml of EM bacteria in the first round of activated bacterial solution, and incubate at 35°C for 3 days; in the third round of EM bacteria activation, mix wheat bran and rice bran at a mass ratio of 1:2, and mix every 5 kg Add 100g of brown sugar, 3g ...

Embodiment 3

[0049] A preparation method for microbially active tobacco seedling-growing matrix, comprising the following steps:

[0050] 1) Activation of EM bacteria: for the first round of activation of EM bacteria, add 300ml of water, 60g of brown sugar, 0.5g of salt, and 4g of urea into a 500ml Erlenmeyer flask, dissolve, wrap up, sterilize at 115°C for 20 minutes, take it out, cool to room temperature, and then Add 12g of preserved EM bacteria freeze-dried powder, culture at 35°C for 48 hours; the second round of EM bacteria activation, add 6L of water, 1200g of brown sugar, 50g of salt, and 30g of urea into the serum bottle, dissolve, seal, and sterilize at 115°C for 20 minutes. Take it out, cool to room temperature, insert 80ml of EM bacteria in the first round of activated bacterial liquid, and incubate at 35°C for 3 days; for the third round of EM bacteria activation, mix wheat bran and rice bran at a mass ratio of 2:1, and add Brown sugar 100g, salt 3g, urea 5g, adjust moisture c...

Abstract

The invention discloses a preparation method of a microorganism active tobacco seedling growing base material. The preparation method comprises the following steps: activating EM bacteria; preparing a tobacco seedling growing base material activating agent; and fermenting and preparing the microorganism active tobacco seedling growing base material which is directly used for floating type seedling growing. By sufficiently expressing material properties of a microorganism bacterial agent (EM bacteria) (capable of optimizing base material properties, promoting rooting and reducing diseases and insect pests), organic materials (capable of improving nutritional requirements of tobacco seedlings and promoting expanding propagation of microorganisms) and biomass carbon (with abundant micro-pore structures, large specific surface area, high pH and strong adsorption capability and anti-decomposition capability); the three materials above are organically fused with peat, vermiculite, perlite and the like by utilizing a fermentation engineering technology to prepare the seedling growing base material which has the characteristics of high microbiological activity, capability of continuously and effectively supplying fertility, and good physicochemical environment for development of tobacco seedlings; the seedling growing base material is successfully used for the floating type seedling growing of tobaccos.

Description

technical field [0001] The application belongs to the field of tobacco seedling cultivation, and in particular relates to a method for preparing a microbial active tobacco seedling cultivation substrate. Background technique [0002] "Having harvest or not depends on planting, and harvesting more or less depends on planting." High-quality tobacco products depend on high-quality tobacco leaves. Cultivating high-quality tobacco seedlings is the first hurdle to achieve high-quality tobacco leaf production. Tobacco seedling cultivation in my country has generally adopted tobacco floating seedling cultivation technology, and the seedling cultivation substrate is the basis for tobacco seedling cultivation. [0003] my country is the country with the largest promotion area of ​​floating seedling raising technology in the world. Floating seedling cultivation represents the most advanced seedling cultivation technology in the world today. Under the conditions of greenhouse and plast...
