In-house production technology for hydroponic swamp cabbages

Abstract

The invention discloses an in-house production technology for hydroponic swamp cabbages, belonging to the field of a vegetable technology. The technology comprises the steps of directly seeding swamp cabbage seeds on the matrix surface of a square sponge after the swamp cabbage seeds are sprouted for 1 to 2 days, hydroponically culturing 2 to 3 true leaves with a nutrient solution in a water culture tank, and then seeding swamp cabbage seedlings covered by sponges into planting holes in a cystosepiment floating in the water culture tank, and then placing under a rear earth plant light source with the blue-red combination of 5:2 to culture for 35 days. The rear earth plant light source with the blue-red combination of 5:2 is best for the growth of the swamp cabbages. The in-house production technology provided by the invention has the advantages of simple operation, quick and healthy plant growth, energy saving, environmental protection and the like, thereby being applicable to the fields of the industrialized production of in-house rapid seedling, cultivation, sprouting of the swamp cabbages and the like.

Description

technical field [0001] The invention relates to a technique for indoor production of water spinach, 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. Water spinach, formerly known as Yongcai, also known as rattan vegetable, water spinach, spinach, macaroni, spinach, urn vegetable, empty tube vegetable, bamboo leaf vegetable, has white trumpet-shaped flowers and the center of the stalk is empty, so it is called "Spinach". It is widely cultivated as vegetables in rural areas of southern China. However, there is no mature and reliable technology for the provision of light sources for indoor production of wat...

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
