Problems solved by technology

[0002] Soilless seedling cultivation is the core technology of industrialized seedling cultivation technology reform. Most traditional soilless seedling cultivation adopts solid substrate (for example, the choice of solid substrate recognized at home and abroad is "peat: vermiculite 2-3:1 according to the volume ratio"). For mixed substrates, the nutrient method has always been to water the nutrient solution. The preparation of the nutrient solution is cumbersom

Embodiment 1

[0029] Biochar, peat, vermiculite and perlite are mixed in a volume ratio of 3:2:1:1. In each cubic meter of the original matrix, 2.8 kg of potassium sulfate compound fertilizer, 8.0 g of fulvic acid, and zeolite powder are added. 8.0 kg of agent, 80.0 kg of vermicompost, 10.0 g of chitin, just mix evenly.

Embodiment 2

[0031] Biochar, peat, vermiculite and perlite are mixed in a volume ratio of 3:2:1:1. In each cubic meter of the original matrix, 2.8 kg of potassium sulfate compound fertilizer, 8.5 grams of fulvic acid, and zeolite powder are added. 7.5 kg of agent, 80.0 kg of vermicompost, 11.0 g of chitin, just mix evenly.

Embodiment 3

[0033] Biochar, peat, vermiculite and perlite are mixed in a volume ratio of 3:2:1:1. In each cubic meter of the original matrix, 2.8 kg of potassium sulfate compound fertilizer, 8.5 grams of fulvic acid, and zeolite powder are added. 7.0 kg of agent, 80.0 kg of vermicompost, 12.0 g of chitin, just mix evenly.

Abstract

The invention discloses a biological carbon nutrient substrate for raising tobacco seedlings without soil. The formula comprises an original substrate containing biological carbon, peat, vermiculite and perlite with a volume ratio of (2-3):2:1:1, and 2.5-3.0kg of potassium sulphate-type compound fertilizer, 8-10g of fulvic acid, 5-8kg of a zeolite powder adsorbing agent, 80kg of wormcast, and 10-15kg of chitin are added to each cubic meter of the original substrate, and uniform mixing is performed. The biological carbon nutrient substrate for raising the tobacco seedlings without the soil disclosed in the invention can satisfy the growth and development requirements in a whole tobacco seedling stage, have multiple effects of nutrition, drought resistance and disease resistance, and is suitable for promotion and application.

Description

technical field [0001] The invention relates to the technical improvement of the tobacco seedling raising substrate, in particular to the preparation of the nutrient substrate for the soilless seedling raising of the biochar tobacco, and belongs to the field of industrialized seedling raising in agriculture. Background technique [0002] Soilless seedling cultivation is the core technology of industrialized seedling raising technology reform. Most of the traditional soilless seedling cultivation adopts solid substrate (for example, the choice of solid substrate recognized at home and abroad is the compound of "peat: vermiculite 2-3:1 according to the volume ratio". For mixed substrates, the nutrient method has always been to water the nutrient solution. The preparation of the nutrient solution is cumbersome and expensive, and a certain preparation container and irrigation machinery are required. There are certain risks, and it is not easy to control watering too much and wat...
