Embodiment 1

[0020] Plant the seedlings of green stems or Chinese cabbage with the same specifications into the cultivation equipment and divide them into two groups. The first group is only irradiated with conventional white light, and the second group is irradiated with low-dose UV-B light for conventional white light ( figure 1 ). Set the light environment parameters as follows: the photon flux density of conventional white light is 80 μmol m -2 ·s -1 , the light time is 14h / d, and the light quantum flux density of low-dose UV-B light is 3μmol·m -2 ·s -1 , the light time is 3h / d, and the ambient temperature is 20-24°C.

[0021] During the test, the rosette diameter was counted every 7 days, and the chlorophyll content was detected on the 14th day.

[0022] After growing for the same number of days under the above two conditions, we observed the morphology of Qinggengcai and Sijiucaixin, and found that only under conventional white light irradiation, Qinggengcai and Sijiucaixin grew ...

Abstract

The invention provides a lighting culture method capable of increasing size and promoting green for green terrier and brassica parachinensis bailey, and relates to planting and culturing of green terrier and brassica parachinensis bailey. In the seedling growth period of the green terrier and the brassica parachinensis bailey, an artificial light source is adopted for irradiating green terrier andbrassica parachinensis bailey seedlings, growth of leaves of the green terrier and brassica parachinensis bailey seedlings is facilitated, leaves change green, and chlorophyll is accumulated. A lightsupply manner of the artificial light sources adopts conventional white light and low-dosage UV-B lighting. The wavelength of low-dosage UV-B light is 280-320nm, and light quantum flux density is 3<mu>mol.m<-2>.s<-1>. The method disclosed by the invention is suitable for growth of total artificial light green terrier and brassica parachinensis bailey seedlings. The lighting method is adopted, sothat growth of the green terrier and brassica parachinensis bailey seedlings can be promoted, the production cycle can be shortened, and energy consumption is reduced. The method is simple and convenient to operate, and has wide application space and market prospects for agricultural modernization production.

Description

technical field [0001] The invention relates to the planting and cultivation of green stem vegetables and four-nine Chinese cabbage hearts, in particular to a light cultivation method for promoting the growth and greening of green stem vegetables and four-nine Chinese cabbage hearts. Background technique [0002] Light is one of the most important environmental factors affecting the life activities of animals and plants. It is not only the energy source of plant photosynthesis, but also acts as a signal molecule to regulate multiple processes of plant growth and development. UV-B light is an inherent part of sunlight, and high doses of UV-B light can cause plant damage, while low doses of UV-B light can act as a signal factor to promote the photomorphogenic response of plants. [0003] The artificial light plant factory is a form of facility that relies on artificial light sources to provide crops with a growth light source and the environment is precisely adjustable. Leaf...
