Embodiment 1

[0045] A special substrate for flue-cured tobacco floating seedlings, comprising the following components by volume:

[0046] 6.5 servings of fermented crushed corncobs

[0047] Vermiculite 1.5 parts

[0048] 1.5 parts of expanded perlite

[0049] Magangsa 0.8 parts

[0050] The preparation method of the fermented crushed corncob is as follows: first expose the corncob to the sun at 50°C, adjust the moisture content of the straw to 30%, cover with film, retting, ferment until decomposed, dry and crush to obtain the fermented crushed corncob. The pH value of the fermented crushed corncob is 6, and the particle size of the fermented crushed corncob is 1um.

[0051] According to the above components by volume, the fermented crushed corn cob, vermiculite, puffed perlite and magang sand are uniformly mixed to obtain the special substrate for floating seedling cultivation of flue-cured tobacco. The pH value of the special substrate for flue-cured tobacco floating seedlings is 5....

Embodiment 2

[0077] A special substrate for flue-cured tobacco floating seedlings, comprising the following components by volume:

[0078] 7 servings fermented corn cobs

[0079] 1 part vermiculite

[0080] 1 part expanded perlite

[0081] Magangsa 0.5 part.

[0082] The preparation method of the fermented crushed corn cob is as follows: first expose the corn cob to the sun at 80°C, adjust the moisture content of the straw to 40%, cover with film, retting, ferment until decomposed, dry and crush to obtain fermented crushed corn Cobs, the pH value of fermented crushed corncobs is 6.3, and the particle size of fermented crushed corncobs is 3um.

[0083] According to the above components by volume, the fermented crushed corn cob, vermiculite, puffed perlite and magang sand are uniformly mixed to obtain the special substrate for floating seedling cultivation of flue-cured tobacco. The pH value of the special substrate for flue-cured tobacco floating seedlings is 6, and the bulk density is ...

Embodiment 3

[0107] A special substrate for flue-cured tobacco floating seedlings, comprising the following components by volume:

[0108] 6 servings fermented corncobs

[0109] 2 parts vermiculite

[0110] 2 parts expanded perlite

[0111] 1 serving of Magangsa.

[0112] The preparation method of the fermented crushed corn cob is as follows: first expose the corn cob to the sun at 100°C, adjust the moisture content of the straw to 50%, cover with film, retting, ferment until decomposed, dry, and crush to obtain fermented crushed corn core. The pH value of the fermented crushed corncob is 7, and the particle size of the fermented crushed corncob is 5um.

[0113] According to the above-mentioned components by volume, after the fermented crushed corncob, vermiculite, expanded perlite and magang sand are mixed evenly, the special substrate for floating seedling cultivation of flue-cured tobacco is obtained. The pH value of the special substrate for floating seedling cultivation of flue-cu...

Abstract

The invention relates to the technical field of organic seedling substrate and in particular to a special substrate for float seedling of flue-cured tobaccos and a preparation method of the special substrate. The special substrate for float seedling of flue-cured tobaccos comprises the following components in parts by volume: 6-7 parts of fermented smashed corncobs, 1-2 parts of vermiculite, 1-2 parts of expanded perlite and 0.5-1 part of Magang sand. The substrate disclosed by the invention is high in root activity, high in emergency rate, short in seedling time, good in nutrient absorption and good in overall growth vigor of tobacco seedlings, and all parameters are superior to those of the existing tobacco seedling substrate. By using the special substrate, the corncobs are also sufficiently utilized, so that the problem of environment pollution of the corncobs serving as organic wastes can be solved, the aims of utilizing the wastes and changing waste material into things of valueare achieved, the cyclic utilization of natural resources is realized, and the industrialized production of float seedling of flue-cured tobaccos and the sustainable development of the tobaccos are favorably promoted.

Description

technical field [0001] The invention relates to the technical field of organic seedling raising substrates, in particular to a special substrate for flue-cured tobacco floating seedling raising and a preparation method thereof. Background technique [0002] Tobacco is an important economic crop, and tobacco is produced on all continents. my country is the world's largest producer of flue-cured tobacco. More than 1 million hectares of tobacco are planted all year round, and the annual output of tobacco leaves reaches more than 2 million tons. Tobacco has become the main pillar industry in some domestic smoking areas. How to adopt scientific cultivation techniques to promote the healthy development of flue-cured tobacco production is of great significance for improving the quality of flue-cured tobacco in my country, promoting the sustainable development of the tobacco industry and the prosperity of the regional economy. [0003] Seedling raising is an important link in the p...
