Method for cultivating mesembryanthemum crystallinum L. using LED light source

Abstract

The invention relates to a method for cultivating mesembryanthemum crystallinum L. using an LED light source, and belongs to the field of cultivation of medicinal plants. The method comprises sowing seeds of the mesembryanthemum crystallinum L. in a flat plate or a plug tray taking vermiculite as a matrix, watering to make the matrix totally wet, putting the flat plate or the plug tray on a three-dimensional cultivation shelf in a plant factory having an LED light source, and spraying water to keep the matrix wet, wherein the temperature in the plant factory is within the range from 20 DEG C to 23 DEG C; irradiating seedlings after the seeds germinate, and spraying a nutrient solution to cultivating the seedlings; distributing the seedlings after two leaves and one core grows up on each seedling, cleaning the matrix on roots of the seedlings, fixedly planting the seedlings on field planting plates of a three-dimensional multilayer hydroponic system in the plant factory via sterilized sponge, irradiating the seedlings, supplying a nutrient solution by an automatic circulatory system, cultivating; and harvesting in 60 to 70 days after sowing. The production period of the mesembryanthemum crystallinum L. can be fixed, the mesembryanthemum crystallinum L. can be produced and supplied year round, the mesembryanthemum crystallinum L. is safe without pesticides, and contains no heavy metal, more functional substances of the mesembryanthemum crystallinum L. can be accumulated in a controllable environment.

Description

Technical field [0001] The present invention relates to a cultivation method of IcePlant under LED light source, in particular to the cultivation technology of IcePlant under LED light source in plant factory, and belongs to the technical field of medicinal plant cultivation. Background technique [0002] Artificial light technology is one of the most important technologies in plant factory technology, and it is also the most important part that distinguishes it from other technologies. It not only directly affects the production of plants, but is also closely related to operating costs. The development of artificial light technology with high light efficiency and energy saving is the key to the popularization of plant factories. [0003] Currently, the most commonly used light sources in production are sodium lamps, fluorescent lamps, etc., but they have the problems of short service life and poor light efficiency. LED light sources are light-emitting diodes (LEDs). LED lig...
