Embodiment 1

[0025] A kind of organic smoke seedling raising substrate, this substrate is that distiller's grains after fermentation and decomposing respectively, aloe residue and peat, phosphate rock powder, volcanic stone, vermiculite are mixed according to the volume ratio of 1:2:1:1:2:3, Each component should be measured in its natural state, and operations such as compaction are not required.

[0026] Specifically adopt the following method to prepare:

[0027] (1) Preparation of decomposed aloe dregs: pulverize aloe dregs to a length of 1cm-3cm, adjust the water content to 65wt.%, add fermentation bacteria by 10% of the total weight of aloe dregs, and simultaneously press 10% of the total weight of aloe dregs Add phosphate rock powder and add it for stacking fermentation and decomposing. The temperature of the fermentation pile is higher than 50°C for more than 10 days. When the germination test, the germination index GI≥60%, the decomposed material is air-dried and crushed through ...

Embodiment 2

[0031] A kind of organic smoke seedling raising substrate, this substrate is that distiller's grains after fermenting and decomposing respectively, aloe residue and peat, phosphate rock powder, volcanic stone, vermiculite are mixed according to the volume ratio of 2:1:2:1:2:2, Each component should be measured in its natural state, and operations such as compaction are not required.

[0032] Specifically adopt the following method to prepare:

[0033] (1) Preparation of decomposed aloe dregs: pulverize aloe dregs to a length of 1cm-3cm, adjust the water content to 65wt.%, add fermentation bacteria by 10% of the total weight of aloe dregs, and simultaneously press 10% of the total weight of aloe dregs Add phosphate rock powder and add it for stacking fermentation and decomposing. The temperature of the fermentation pile is higher than 50°C for more than 10 days. When the germination test, the germination index GI≥60%, the decomposed material is air-dried and crushed through a ...

Embodiment 3

[0037] An organic smoke seedling raising substrate, the substrate is to mix the respectively fermented and decomposed distiller's grains with peat, phosphate rock powder, volcanic rock, and vermiculite according to the volume ratio of 1:2:1:2:4, wherein each component is in When measuring, the natural state shall prevail, and operations such as compaction are not required.

[0038] Specifically adopt the following method to prepare:

[0039] (1) Preparation of decomposed distiller's grains: add phosphate rock powder by 10% of the total weight of distiller's grains, adjust the water content of the mixture of distiller's grains and phosphate rock powder to be 60-70wt.% and carry out stacking fermentation and decomposing. The temperature of the fermentation heap is 40-45 ℃, when the temperature in the center of the fermentation pile exceeds 60°C, turn the pile to ensure uniform fermentation inside and outside; when the temperature of the fermentation pile drops to ambient tempera...

Abstract

The invention discloses an organic tobacco seedling growing base material and a preparing method and application of the organic tobacco seedling growing base material, and belongs to the technical field of agricultural seedling growing. The composite base material is prepared by evenly mixing vinasse, aloe residues, turf, powdered rock phosphate, pelelith and vermiculite according to the size ratio of 1-2:1-2:2:1:2:2-4. According to the organic tobacco seedling growing base material, the main raw materials include the vinasse, the aloe residues, the powdered rock phosphate, the pelelith and the like, the organic requirement of organic tobacco seedling growing can be met, and grown tobacco seedlings are better than tobacco seedlings grown through a conventional seedling growing base material in the aspects of the strong seedling index, the root activity, the leaf chlorophyll content, the transplanted seedling survival time, the yield and the disease resistance; the utilization amount of the turf which serves as the main component of a current seedling growing base material can be greatly reduced. The pollution of organic waste such as the vinasse to the environment can be overcome, and resources can be recycled; in addition, the cost problem of the seedling growing base material can be solved, and the certain social benefits, the certain economical benefits and the certain ecological benefits can be achieved.

Description

technical field [0001] The invention belongs to the technical field of seedling-raising substrates for agricultural production, and in particular relates to an organic tobacco seedling-raising substrate using organic wastes in Yunnan as raw materials, a preparation method and application thereof, which meet the requirements for planting organic tobacco and are suitable for floating seedlings of flue-cured tobacco. Background technique [0002] Yunnan is a large flue-cured tobacco production province, ranking first in the country in terms of planting area and tobacco leaf output. The unique light, heat, water and soil conditions enable the growth of high-quality flue-cured tobacco, which is also the main pillar industry of local agriculture. Therefore, how to improve the planting level of flue-cured tobacco is of great significance to the healthy development of Yunnan flue-cured tobacco industry and the stability of regional economy. [0003] In the late 1990s, China National...
