Method for rapid propagation of tomato seedlings by air culture

Abstract

The invention discloses a method for rapid propagation of tomato seedlings by air culture. The method comprises the following steps: construction of an air culture seedbed, establishment of a water supply system of the air culture seedbed, construction of a physical disinfection system composed of an ozone generator, a collection and treatment method of tomato in-vitro materials, a management method of the tomato in-vitro materials when the tomato in-vitro materials are put in the air culture seedbed, and a transplantation method after the tomato in-vitro materials are rooted. According to themethod disclosed by the invention, the substrate-free air culture seedbed is established in the implementation process, plant cuttings are in a substrate-free environment, so that the plant cuttingscan sufficiently obtain carbon dioxide and oxygen, formation of callus of grafting unions is facilitated, and the callus is rooted to form seedlings as soon as possible; the method saves investment ofsubstrate materials, and ensures that the production environment is clean and pollution-free; an optimal parameter of environmental humidity is artificially set by a timer to command a water pump tospray water and mist to create a very good growth environment for the plant in-vitro materials cultivated in the air culture seedbed, so that the plant in-vitro materials are rooted to form the seedlings as soon as possible; and automation of the whole seedling raising process is realized, and a large amount of management labor is saved.

Description

technical field [0001] The invention relates to the technical field of asexual propagation of plants, in particular to a method for rapid propagation of tomato seedlings through aeroponic cultivation. technical background [0002] Currently, the tomato propagation method is usually to propagate by seeds. Its reproduction method is roughly as follows: [0003] 1. Soil preparation. Prepare nutrient soil according to a certain ratio. It is required that the porosity of nutrient soil is about 60%, ph6-7, containing more than 100 mg / kg of available phosphorus, more than 100 mg / kg of available potassium, and 150 mg / kg of available nitrogen. Water retention, complete nutrition. Spread the prepared nutrient soil evenly on the seeding bed (thickness 10 cm), or in the seedling tray. [0004] 2. Seed treatment. Seed soaking in warm soup means soaking the seeds in clear water for 1-2 hours, then remove the seeds and put them in hot water at 55 degrees Celsius, keep the water temper...

Problems solved by technology

[0008] The traditional tomato breeding method is cumbersome, the time period from sowing to seedlings is long, and it takes a lot of man-hours, and when the management is improper, tomato seedlings will produce leaf mold, canker, early blight, viral diseases, etc. during the growth process. disease

In addition, the current tomato seeds are relatively expensive, and the breeding cost is high
