Description
Technical Field
The invention relates to the technical field of plant factory planting, in particular to a luminous environment regulation and control method for regulating and controlling the growth and development of a hevea brasiliensis root system.
Background
Natural rubber is an important strategic material and industrial raw material. The rubber grass is also called as Russian dandelion, is a perennial herb of Taraxacum of Compositae, has latex at the root and more than 20% of rubber in the root system, can extract rubber, is used for manufacturing general rubber products, has excellent quality, is commonly called as three glue-producing plants in the world together with Brazilian rubber tree and guayule, and is one of important glue-producing crops which are concerned in recent years.
At present, the rubber grass is mainly cultivated in open fields, is easily limited by natural environment, can not realize annual cultivation production, has no report of indoor rubber grass cultivation, and lacks a technology for regulating and controlling the expansion of the root of the rubber grass by some technical means.
The light is used as an important environmental factor in the growth and development process of plants, not only provides energy for photosynthesis, but also is used as an environmental signal factor, and plays an important role in the aspects of plant morphogenesis and growth and development. The literature shows that the light has the function of regulating and controlling plant seed germination, root growth, stem growth, leaf growth, flowering and the like. Although the root system is not directly irradiated by light, the light can pass through the internal light environment, is transmitted to the underground root from the overground part under the regulation of a light receptor, and regulates and controls the growth and development of the root system.
However, in the prior art, although red light and blue light are the main absorption bands for plant growth and development, the light quality affects the control of the plant root growth and development, and the light quality has been studied on the growth of the plant root. The research of the Korean English shows that the red light has no influence on the formation of the root system shape of the purple pakchoi or inhibits the growth of the root system. The study on the influence of different light qualities on the growth and physiological characteristics of the tomato seedlings proves that the development of the root systems of the tomato seedlings is relatively unfavorable under red light treatment. Researches of Wikstra et al find that the combined treatment of more red light and less blue light is not beneficial to the growth of the root system of the sightseeing wood nursery stock. Therefore, the light quality plays an important role in regulating the growth and development of the root system. However, the growth of the light quality control root system is different according to different plant varieties. In the prior art, a specific scheme of a luminous environment formula for accurately regulating and controlling the growth and development of the roots of the hevea brasiliensis is not provided, so that the annual production of the hevea brasiliensis can be realized, and the expansion of the roots of the hevea brasiliensis can be promoted.
