Indoor production technology for water planted sonchus oleraceus

Abstract

The invention discloses an indoor production technology for water planted sonchus oleraceus, and belongs to the technical field of vegetables. The indoor production technology includes the steps that after sprouted for two to three days, seeds of the sonchus oleraceus are directly seeded on the surface of sponge square block matrixes, water planting is carried out on seedlings in a nutrient solution till each seedling has four main leaves, then the seedlings of the sonchus oleraceus are wrapped by sponges to be seeded into planting holes in a foam panel floating in a water planting groove, and then water planting is carried out for fifty days under combined LEDs, wherein the blue LEDs, the red LEDs and the yellow LEDs are 5:2:1 in ratio. A combined light source with the blue LEDs, the red LEDs and the yellow LEDs 5:2:1 in ratio is most suitable for growth of the sonchus oleraceus. The indoor production technology has the advantages that operation is simple, plants are rapidly and robustly grown, energy is saved, and the environment is protected, and can be applied to the fields such as industrialized production of indoor rapid seedling growing, planting and seedling planting of the sonchus oleraceus.

Description

technical field [0001] The invention relates to a technology for indoor production of hydroponic chicory, belonging to the technical field of vegetables. Background technique [0002] Hydroponic vegetables refer to vegetables whose roots grow in layers of nutrient solution and only provide water, nutrients, and oxygen through nutrient solution, which is different from traditional soil cultivation. Hydroponic vegetables have a short growth cycle and are rich in a variety of vitamins and minerals necessary for the human body. Chicory is a plant of the genus Chicory in the Compositae family, also known as bitter cabbage and dog tooth lettuce. It has antibacterial, antipyretic, anti-inflammatory, and eyesight effects. Bitter chrysanthemum has a slightly bitter taste and is green in color. It can be fried or served cold. Because of its sweet and slightly bitter taste, and the effect of clearing heat and relieving summer heat, it has been widely praised. However, there is no ma...

Problems solved by technology

The artificial light sources used in agriculture and biology for a long time mainly include fluorescent lamps, incandescent lamps, sodium lamps, and dysprosium lamps. Among them, high-pressure sodium lamps and dysprosium lamps are light sources with high luminous efficiency and effective photosynthetic efficiency, but they consume a lot of power and emit spectrum. It cannot be well matched with the photosynthetic absorption spectrum of plants, and the efficiency of supplementary light is low; and it produces a lot of heat radiation, which cannot be close to the plants, and the light excitation efficiency for plant growth is not high, and the cost of artificial light sources is very high
