Embodiment 1

[0030] The tea dregs used in the seedling raising substrate of this example are from Nanjing Rongdian Food Technology Co., Ltd., and the batch of tea dregs is B02-25.

[0031] The specific operation steps of the preparation of the seedling-raising matrix of the present embodiment are as follows:

[0032] A. Tea residue humidity adjustment

[0033] Add a desiccant to the tea dregs with a water content of 75-90% to make the humidity reach 50-60%;

[0034] B. Tea dregs crushing

[0035] The tea dregs after the humidity adjustment in the previous step are directly coarsely crushed to a particle size of less than 5 mm;

[0036] C. Fermentation of tea dregs

[0037] After crushing, 0.5 kg of agricultural microbial fermentation agent is evenly mixed into every cubic tea dregs, and the pile is used for high-temperature aerobic fermentation. The fermentation cycle is 15-40 days. 20 to 30 days, 25 to 40 days in winter, so that the fermented product formed after fermentation of tea d...

Embodiment 20

[0051] Take 20 g of the fully fermented tea dregs and peat in this example as two substrates respectively, among which peat is used as the reference substrate, add 200 mL of distilled water, stir thoroughly, and fully extract in a constant temperature shaker at 25°C and 220 rpm. The solution was autoclaved and cooled to room temperature. Vegetable seeds of Chinese cabbage-Gaojiaobai, Chinese cabbage-Suzhouqing, pepper-Sujiao No. 5, cucumber-Ningfeng No. 4, tomato-Bauda 903 are used as seed materials, and peat and tea dregs extract are used respectively As the material, three repetitions were set for each group, and the germination rate of each vegetable seed was counted. The test data are shown in Table 2.

[0052]

[0053] Table 2 Germination rate of vegetable seeds

[0054]

[0055] The results in Table 2 show that the germination rate of various vegetable seeds using tea dregs as a substrate is higher than 95%, and it is determined that tea dregs can be used as a seedl...

Embodiment 2

[0068] The tea dregs used in the seedling raising substrate of this example are from Nanjing Rongdian Food Technology Co., Ltd., and the batch of tea dregs is B02-25.

[0069] The specific operation steps of the preparation of the seedling-raising matrix of the present embodiment are as follows:

[0070] A. Tea residue humidity adjustment

[0071] Add a desiccant to the tea dregs with a water content of 75-90% to make the humidity reach 50-60%;

[0072] B. Tea dregs crushing

[0073] The tea dregs after the humidity adjustment in the previous step are directly coarsely crushed to a particle size of less than 5 mm;

[0074] C. Fermentation of tea dregs

[0075] After crushing, 1.0 kg of agricultural microbial fermentation agent is evenly mixed into every cubic tea dregs to make a stack for high-temperature aerobic fermentation. The fermentation cycle is 15 to 40 days. 20 to 30 days, 25 to 40 days in winter, so that the fermented product formed after the fermentation of tea ...

Abstract

The invention relates to a seedling cultivating substrate and a preparation method thereof, and belongs to the technical field of seedling cultivating substrate development. The seedling cultivating substrate comprises the following components, by volume percentage, 68-72% of fermentation materials, 8-12% of vermiculite, 12-16% of crop stalks and 4-8% of perlite. According to the preparation method of the seedling cultivating substrate, the humidity of tea residues is adjusted to reach 50-60%; then the tea residues are smashed directly, farm-oriented microbial fermentation fungus agents are mixed in each stere of smashed tea residues and are stirred evenly, and pile layers are made to carry out high temperature aerobic fermentation; finally the fermented substances is mixed with the vermiculite, the crop stalks and the perlite. According to the seedling cultivating substrate and the preparation method thereof, the pollution of tea residues can be eliminated, the ecological environment of China can be improved, and the seedling cultivating substrate can shorten seedling cultivating cycles.

Description

technical field [0001] The invention relates to a seedling-raising substrate made of tea dregs and a preparation method thereof, belonging to the technical field of seedling-raising substrate development. Background technique [0002] Tea products are popular consumer goods, but at present, middle and high-grade teas are easy to sell, while low-grade teas are seriously unsalable. There are hundreds of thousands of tons of low-grade tea in the country every year. In the past 10 years, the production of deep-processed tea products such as tea beverages, instant tea and tea polyphenols in my country has increased rapidly, and tea beverages rank third among all beverages after drinking water and carbonated beverages. After the 1990s, with the application of membrane technology and freeze-drying technology to the preparation of instant tea, the production technology of instant tea tended to mature, and the instant tea market gradually increased. At present, the annual output of ...
