Problems solved by technology

[0007] In order to solve the problem of cross-infection of pathogenic sources, the present invention constructs a one-way infusion water culture device, each plant hydroponic device is relatively independent, and communicates with the entire hydroponic system through the one-way input and output of nutrient solution, and at the same time realizes the The nutrient solution used by the plants is relatively independent, avoiding the exchange and sharing of nutrient solution between plants, realizing the separate use of each planting nutrient solution, and preventing cross-infection of tobacco diseases through nutrient solution exchange
[0008] In addition, the present invention chooses opaque materials or coats light-shielding materials to solve the problem of hydroponic green algae breeding, and can automatically adjust the water level of the nutrient solution to solve the problem that the water level of the nutrient solution caused by the opaque materials is not easy to observe

Embodiment 1

[0056] According to attached figure 1 Form an automatic nutrient solution delivery device.

[0057] Single-plant hydroponic device: a shading hydroponic cup with a diameter of 8cm and a height of 10cm, the cup cover is concaved by 2cm; the diameter of the planting cup is 5cm, the height is 5cm, and the diameter of the fixed edge of the planting cup is 0.5cm larger than that of the hydroponic cup, and it can bear weight More than 2kg in weight. The height of the nutrient solution was set to 8cm.

[0058] The gene-edited tobacco and the female parent control tobacco were raised in normal floating. After the tobacco seedlings reached the standard of normal transplanting and strong seedlings, 20 tobacco seedlings with uniform growth and uniform size were selected for transplanting. When transplanting, pull out the tobacco seedlings from the seedling tray, wrap the tobacco roots with black polyester fiber (wrapped together with the seedling growth substrate attached to the roots)...

Abstract

The invention discloses a gene-edited tobacco one-way liquid-conveying and multi-plant automatic hydroponic device. The device comprises a liquid conveying metering pump (1), a liquid input main pipe (2), a liquid output main pipe (3), liquid input branch pipes (4), liquid output branch pipes (5), a field planting plate (6), single-plant hydroponic units (7), hydroponic cup liquid level monitoring sensors (8) and a liquid level control computer. The one-way liquid-conveying hydroponic device is constructed, each plant hydroponic device is relatively independent and communicates with the whole hydroponic system through one-way input and output of a nutrient solution, independent use of the nutrient solution is achieved, and cross infection of tobacco diseases due to nutrient solution exchange is prevented; meanwhile, each liquid level monitoring sensor monitors the water level in real time and is matched with a conveying pump, and automatic water culture of plants is achieved; and the equipment is low in cost and simple to operate, can realize automatic planting, saves a large amount of labor, and can be directly used for screening of tobacco gene editing materials and factory-like hydroponic planting.

Description

technical field [0001] The invention belongs to the field of tobacco cultivation, and in particular relates to an automatic hydroponic device and method for one-way infusion of gene-edited tobacco and its application in screening gene-edited materials. 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 man...
