Gene editing tobacco single plant hydroponic device and hydroponic method

Abstract

The invention discloses a gene editing tobacco single plant hydroponic device and a hydroponic method. The gene editing tobacco single plant hydroponic device comprises a hydroponic cup (4), a field planting cup (3), a water absorption line (7) and a water level observation pipe (8), wherein a hydroponic cup cover (2) is arranged at the top of the hydroponic cup (4), the field planting cup (3) is fixed on the upper part of the hydroponic cup (4) through the hydroponic cup cover (2), and tobacco seedlings (1) and a substrate for culturing the tobacco seedlings (1) are loaded in the field planting cup (3); the water level observation pipe (8) is positioned in the hydroponic cup (4) and is used for observing the water level height of a nutrient solution (5) in the hydroponic cup (4); and the hydroponic cup (4) and the hydroponic cup cover (2) are black and light-proof. A single-plant hydroponic device is constructed, a nutrient solution of each plant is independently added, exchange and sharing of the nutrient solution among plants are avoided, and cross infection of tobacco diseases due to nutrient solution exchange is prevented. In addition, the problem of breeding of hydroponic green algae is solved by selecting a light-proof material or coating a shading material.

Description

technical field [0001] The invention belongs to the field of tobacco cultivation, and in particular relates to a gene-edited tobacco single-plant hydroponic device and a hydroponic method, and its application in gene-edited material screening. Background technique [0002] Tobacco is an important economic crop in my country, and it is also a commonly used model plant for molecular genetics research. Tobacco traits are not only affected by its own genetic material, but also by planting environmental factors. Planting conditions such as different temperature, climate and soil have a great influence on the traits, yield and quality of tobacco. [0003] Hydroponics is a relatively advanced cultivation method in soilless cultivation, which directly contacts the root system of the plant with the nutrient solution. The production of plants that are nourished by a nutrient solution. Hydroponics can precisely control the growth and development of plants and is easy to manage. The...

Problems solved by technology

[0007] In order to solve the problem of cross-infection of pathogenic sources, the present invention constructs a single-plant water culture device, and the nutrient solution of each plant is added separately, which avoids the exchange and sharing of nutrient solution between plants, realizes the separate use of each planting nutrient solution, and prevents tobacco Disease cross-infection through nutrient solution exchange

In addition, the present invention chooses opaque materials or coats light-shielding materials to solve the problem of hydroponic green algae breeding, and at the same time adds a water level observation tube 8 to observe the water level of the nutrient solution in the hydroponic cup simply and efficiently.
