Method for cultivating red celery in plant factory

Abstract

The invention provides a method for cultivating red celery in a plant factory. The method includes: cultivating the red celery indoors by utilizing artificial light and a water cultivating technologyin a seed germination stage, a seedling stage, a field planting stage and a harvesting stage, controlling nutrient solution conductivity, pH (potential of hydrogen), and temperature and humidity environments of the red celery, and setting corresponding light intensity and light illumination time according to growing habits of the red celery in different stages. The method for cultivating the red celery in the plant factory has the advantages that by cultivating the red celery in different light environments, limits to the red celery from seasons and temperatures are eliminated, annual and clean production of the red celery can be realized, a germination rate of the red celery is guaranteed, a growing period of the red celery is shortened, the red celery can grow stronger, yield per unit area is increased, and excellent and stable conditions and flavor of the red celery are guaranteed.

Description

technical field [0001] The invention relates to a plant factory cultivation technology of red celery, in particular to a plant factory cultivation method of red celery. Background technique [0002] Red celery (Red Celery) is an emerging special vegetable variety of the genus Celery in the family Umbelliferae. It is a new variety cultivated in my country in recent years. The growth period is about 90 days. The petiole is red, rich in calcium, iron and other trace elements. Rich in nutrition, it is suitable for cold salad and fried food. The petiole can also be squeezed as a celery juice drink. It is a vegetable variety with high value. Under the conditions of the facilities, it can be produced every year and be marketed all year round. It is known as "vegetables without seasons". The color of red celery is special, the petiole is red, and the leaves are green. As the plant grows, the color of the petiole gradually fades from the inside to the outside. The inner petiole is re...

AI Technical Summary

Problems solved by technology

However, there are the following problems in the cultivation of red celery: the seeds of red celery are small, the seed coat is thick, the water permeability is poor, and the germination is slow; the cultivation is greatly affected by climate and season; Less pigment accumulation, lighter color; long growth cycle, for small celery cultivation (plant height 20-30cm), the growth period generally takes about 90 days, for medium plant and large plant cultivation (plant height 60cm), the growth period takes half a year above; continuous cropping obstacles are obvious, and crop rotation needs more than 2 years

In order to prevent diseases, it is necessary to use chemicals to sterilize and disinfect in advance, or use chemicals to control after the outbreak of diseases and insect pests, and after harvesting, it is necessary to select another suitable land for planting, and continuous farming is not allowed

The growth cycle of red celery is long, and it needs to prepare the soil and apply basal fertilizer three months in advance. It takes at least three months to plant after the seedlings are raised, which consumes a lot of land, space, labor and time.

[0004] In summary, due to the long germination time of red celery, the germination rate is relatively low, the germination process is complicated, the growth rate is slow, the soil cultivation management is cumbersome, and the cost of planting and pest control is relatively high.
