Embodiment 1

[0018] Embodiment one: a vermiculite substrate for flue-cured tobacco seedling cultivation, which is formed by mixing vermiculite and perlite, and the expansion factor of perlite is greater than 10, wherein the ratio of the dry matter volume of vermiculite to the dry matter volume of perlite is 1: 1, The density of vermiculite is between 150 and 180 kg / m 3 , the particle size ranges from 1 to 5 mm. The selected vermiculite must have good permeability, good water absorption, no toxic side effects, uniform particles, no pollution, less mud and no impurities. Perlite comes from industrial raw materials.

[0019] A method for cultivating tobacco seedlings by using the above-mentioned vermiculite substrate for flue-cured tobacco seedling cultivation, the steps of which are: putting the vermiculite substrate for flue-cured tobacco seedling cultivation into a foam seedling cultivation tray, planting seeds in the tray, and putting the seedling cultivation tray into a seedling cultiva...

Abstract

The invention discloses a vermiculite substrate for culturing tobacco seedlings, which belongs to the technical field of tobacco seedling culturing and aims at solving the damage to the ecological environment caused by using grass peat in the existing seedling culturing substrate. The invention provides a tobacco seedling culturing vermiculite substrate which is mixed by vermiculite and perlite. The invention also provides a method for culturing tobacco seedlings. The method comprises the steps of: arranging the vermiculite substrate in a seedling culturing tray, seeding, adding water into a seedling culturing pool, adding nutrition liquid after the tobacco seedlings erupt completely, carrying out thinning, replanting, leaf cutting as well as seedling hardening during the growing period and finally carrying out transplanting. The substrate used for seedling culturing has the advantages of high rate of emergence, high planting percent and low cost; moreover, the grass peat is not used, thus reducing the damage to the ecological environment.

Description

technical field [0001] The invention belongs to the technical field of tobacco seedling cultivation, and in particular relates to a substrate for growing tobacco seedlings, a preparation method of the substrate and a method for cultivating flue-cured tobacco seedlings with the substrate. Background technique [0002] The technique close to the present invention among the existing floating seedling-raising substrates is a seedling-raising substrate mainly composed of perlite, peat and vermiculite. In this matrix formula, peat is an indispensable main raw material. Generally, the proportion in the matrix formula can account for about 30%-50%. Peat generally comes from wetlands with limited reserves. Excessive exploitation of peat will damage wetlands. The ecosystem balance is disrupted. The economic value of peat is relatively high, and the use of peat in the seedling substrate will greatly increase the cost of seedling cultivation. Contents of the invention [0003] In or...
