Industrial production and cultivation system of cordate houttuynia and using method

Abstract

The invention discloses an industrial production and cultivation system of cordate houttuynia and a using method. The cultivation system mainly comprises a supporting structure, a cultivation system,a nutrient solution supply system and a light source. The multi-layer cultivation system can realize multi-layer three-dimensional cultivation of the cordate houttuynia and improve the production efficiency of the cordate houttuynia per unit area; in addition, the arrangement of a light source and a time control device can accurately control the supply of illumination and nutrition in the production process, reduce the waste of resources, and further can observe and record the growth state of the cordate houttuynia at any time; and meanwhile, the root and stem of the cordate houttuynia can bepartially harvested, and the retained root and stem can continue to grow, and thus the continuous harvesting and planting of the cordate houttuynia are realized. A water culture method is adopted toavoid the direct contact between the cordate houttuynia product and the soil, and thus the hygiene and safety of the cordate houttuynia product can be ensured; and compared with the traditional fieldcultivation, the step of post-harvest cleaning is saved, and thus the production efficiency is improved.

Description

technical field [0001] The invention relates to the related fields of modern agricultural planting, in particular to a system for industrialized production and cultivation of fennel roots and a method for using them. Background technique [0002] The plant factory is an efficient agricultural system with controllable environment and multiplied production capacity. It is known as "disruptive technology of land use and farming methods". It can expand cultivated land resources, ensure the supply of vegetable baskets and strategic needs of special places, and is an important part of modern agriculture. Partly, the plant factory has the following advantages and characteristics: 1. The production process is not affected by the external environment, and annual production can be realized; 2. Three-dimensional cultivation can be carried out, with high output per unit area and resource utilization; 3. No pesticide use, product safety High; 4. Less limited by land, production can be ca...

Problems solved by technology

[0003] At present, some leafy vegetables and traditional Chinese medicine plants have achieved plant factory production, and Zheergen, as a characteristic economic crop and medicinal and edible plant in Southwest China such as Sichuan, is favored by the market. At the same time, Zheergen has low demand for light. It meets the design and construction requirements of production-type plant factories. The traditional cultivation of Zheer root is carried out under field conditions. The economic benefits are considerable, and the yield per mu can reach 2500-3000 kg. However, there are still problems such as extensive fertilizer application, complicated harvesting methods, and long cultivation time. and food safety issues. In particular, due to problems such as continuous cropping obstacles and wild germplasm degradation, it is difficult to guarantee the quality of Zheergen, and it is difficult to meet people's dietary health needs.
