Planting method for mesembryanthemum crystallinum in plant factory

Abstract

The invention belongs to the field of agricultural planting, and discloses a planting method for mesembryanthemum crystallinum in a plant factory. The mesembryanthemum crystallinum is illuminated by light emitted by an LED lamp with a ratio of red blue light of 60%-99%; and the planting method comprises the steps of management in a seeding germination-accelerating stage, management in a seedling stage, management in a root recovering stage, management in a base leaf growth stage, management in a branching slow stage, management in a branching robust stage and management in a harvesting stage,wherein the mesembryanthemum crystallinum can be picked after one day of harvesting, the remaining mesembryanthemum crystallinum after picking is completed returns to the branching slow stage, and enters the branching robust stage and a post-harvesting stage for circular picking. The planting method for the mesembryanthemum crystallinum in the plant factory disclosed by the invention has the advantages that planting costs are low and ripening time is fast.

Description

Technical field [0001] The invention belongs to the field of agricultural planting and relates to a planting method of ice vegetable. Background technique [0002] The plant factory is an efficient agricultural system that achieves annual continuous production of crops through high-precision environmental control in the facility. It uses computers to control the temperature, humidity, light, and CO of plant growth. 2 Environmental conditions such as concentration and nutrient solution are automatically controlled, so that the growth of plants in the facility is not restricted or seldom restricted by natural conditions for labor-saving production. The plant factory has a high multiple cropping index, which allows annual production and avoids continuous cropping obstacles. Leafy vegetables are not easy to store, but annual production is needed to meet market demand, so plant factories are particularly suitable for growing leafy vegetables. [0003] In plant factories, the quality of...

AI Technical Summary

Problems solved by technology

In a plant factory with a uniform height, about 2-3 kWh of electricity is needed to produce 100g of ice vegetables. Due to high energy consumption and high heat, a cooling system is required to discharge heat, which further increases the cost of planting

[0006] To sum up, the deficiencies of ice vegetables currently grown in plant factories are: 1. The germination rate is low and the emergence of seedlings is uneven, which is not conducive to the standardization and large-scale production of plant factories; 2. High energy consumption and high planting costs; 3. The nutrient solution, light source, temperature and other facilities and environments used in each growth stage of ice vegetables are consistent, the growth cycle is slow, the branching is slow and the growth is abnormal;
