Problems solved by technology

[0002] The existing flue-cured tobacco floating nursery substrate in my country is still dominated by peat. Peat is a non-renewable resource. Extensive use of peat causes waste of resources. Therefore, my country has restricted the exploitation of peat resources within a reasonable range. This restriction will significantly increase the existing resources. The production and preparation cost of flue-cured tobacco floating seedling cultivation substrate with peat as the main component will significantly increase the price of flue-cured tobacco floating seedling cultivation substrate, which will also directly increase the cost of tobacco seedling cultivation and affect the research and development of tobacco floating seedling cultivation

specific example

[0020] Since 2007, the applicant has carried out research on the alternatives of floating seedling raising substrates in Bozhou. After three years of research, the substrate formula of the present invention has been screened out. Specific examples are as follows:

[0021] The extension test is arranged in Zhangji, Qiaocheng District, Bozhou, and the test time is designed from the end of December 2008 to April 10, 2009, and from August 15, 2009 to the end of October.

[0022] 1) Preparation of fermented biomass: mix biological straw starter + rice husk with a particle size of 2-5 mm or dry corn stalk or dry sorghum stalk + water in a weight ratio of 1: 400: 80, mix evenly at 55- Ferment at a temperature of 60°C for 55-60 days, so that the surface of the rice husk turns from yellow to gray or the surface of corn stalks and sorghum stalks grows white hyphae and emits a peculiar smell. After drying, the color is dark gray.

[0023] 2) Substrate configuration: The above-mentioned ...

Abstract

The invention discloses a flue-cured tobacco float breeding matrix and a preparation method of the flue-cured tobacco float breeding matrix. The matrix comprises main components of fermented rice husks or / and dried corn straws and broomcorn straws and a certain amount of high temperature disinfected mellow soil or deshydratees and puffed pearl. The preparation method mainly comprises the following steps of: performing biomass fermentation, configuring the matrix according to components and performing steam sterilization. The flue-cured tobacco float breeding matrix has the advantages that the fermentation rice husks, the corn straws and the broomcorn straws in the matrix are used as the main components and are waste produced by processing the conventional crops; the substances are easily available and are low in production cost; moreover, the fermented rice husks, the dried corn straws and the broomcorn straws contain rich organic substances; and a demand of tobacco seedlings for nutritious components during growth process can be well met.

Description

technical field [0001] The invention relates to a flue-cured tobacco floating seedling raising substrate and a preparation method thereof. Background technique [0002] The existing flue-cured tobacco floating nursery substrate in my country is still dominated by peat. Peat is a non-renewable resource. Extensive use of peat causes waste of resources. Therefore, my country has restricted the exploitation of peat resources within a reasonable range. This restriction will significantly increase the existing resources. The production and preparation cost of flue-cured tobacco floating seedling raising substrate with peat as the main component will significantly increase the price of flue-cured tobacco floating seedling raising substrate, which will also directly increase the cost of tobacco seedling raising and affect the research and development of floating tobacco seedling raising. Since tobacco floating seedlings have special requirements on the characteristics of the substrat...
