All artificial light control method of leaf vegetable forms

Abstract

The invention discloses an all artificial light control method of leaf vegetable forms. The ratio of the number of photons with the wavelength of 710-740 nm to the number of photons with the wavelength of 400-499 nm in a light environment is 0.87-1.10; the wavelength range of the light environment is 380-780 nm; the proportion of the number of photons with the wavelength of 710-740 nm is 9.3-14.5%; and the specific spectral composition is as follows: the proportion of the number of photons with the wavelength of 400-499 nm is 10-15%; the proportion of the number of photons with the wavelengthof 500-599 nm is 21-27%; the proportion of the number of photons with the wavelength of 600-699 nm is 37-54%; and the proportion of the number of photons with the wavelength of 700-780 nm is 12-22%. In an environment that other growth conditions are kept and the light intensity is same, brassicaceous vegetables, which are upright in plant type, better in waist binding, relatively tight in cabbagecore compactness and relatively compact in whole plant form can be bred in the light environment; and thus, the commodity of leaf vegetables is improved.

Description

technical field [0001] The invention relates to the technical field of plant lighting, in particular to a method for regulating the morphology of leafy vegetables with full artificial light. Background technique [0002] As an important environmental factor in the process of plant growth and development, light not only provides energy for photosynthesis, but also acts as a signal factor that plays an important role in regulating plant morphogenesis and growth and development. Among them, the morphological establishment of plants will be affected by light quality, light intensity, photoperiod, light mode, and light angle. [0003] Leafy vegetables are the main vegetable varieties planted in plant factories at present. In the plant factory environment with limited space, when vegetables are produced, the shape of vegetables will directly affect the planting density and output per unit area. Therefore, some vegetables are often selected in plant factories. Vegetable planting o...

AI Technical Summary

Problems solved by technology

[0006] At present, in the clean space of the plant factory, the cruciferous vegetables produced will not suffer from pests and diseases, but the cruciferous vegetables produced are prone to problems such as the shape of the cabbage is not firm enough, the waist is not tight, and the cabbage is biased. The loose form is not conducive to product packaging first, and secondly, the commodity is also poor

Therefore, it is urgent to take some measures to solve the problems that cruciferous vegetables are not waisted, not upright, and loose in the cultivation of plant factories.
