Problems solved by technology

There may be studies on the four growth stages of rice, but at least two different spectra are proposed, and the lights have to be changed during rice cultivation, which increases equipment procurement costs and management costs
[0008] In addition, the number of light quanta that the existing rice LED lights can provide to rice is far from enough, and the light saturation point of some varieties of rice at the heading stage even reaches 2000 μmol·m -2 ·s -1 The above; the existence of these problems makes it difficult to efficiently plant rice indoors using artificial light sources

Embodiment 1

[0037] A method for cultivating in an LED artificial light environment suitable for the whole growth period of rice, comprising the steps of:

[0038] (1) Disinfect and soak the rice seeds evenly on the soaked seedling paper in the seedling tray, and then cover the top with a layer of soaked seedling paper;

[0039] (2) Place the seedling tray at 28-32°C, and cultivate and accelerate germination in a dark room;

[0040] (3) After the seeds are exposed and the chest is broken, they are placed in the nutrient soil of the 32-hole seedling tray, and cultivated at 24-26° C. to obtain seedlings;

[0041] The specific culture conditions are as follows: the light intensity on the surface of the nutrient soil in the plug tray is 150-250 μmol m -2 ·s -1 , the light cycle is 12-16h / d, and the spectral energy distribution in the above light cycle is as follows:

[0042] The energy at the wavelength of 280-320nm is 0.3-0.5W / m 2, independent power control, light cycle 2h / d (before using...

Embodiment 2

[0048] The spectral energy distribution in step (3) to step (6) of embodiment 1 is preferably:

[0049] The energy at a wavelength of 310nm is 0.35W / m 2 , independent power control, light cycle 2h / d (before using the LED, adjust the smart switch to adjust the UV-B light time to 0:00-2:00), the proportion of light quanta of 380-399nm is 0.05%, and the wavelength is 400-499nm The proportion of light quantum number is 26.56%, the proportion of light quantum number with a wavelength of 500-599nm is 33.27%, the proportion of light quantum number with a wavelength of 600-699nm is 40.17%, and the proportion of light quantum number with a wavelength of 700-780nm The ratio is 2.9%. Its correlation spectrum is as Figure 1-2 shown.

[0050] The rest of the planting steps and related parameters remained unchanged.

[0051] In order to highlight the beneficial effects of the present invention, the following comparative examples are cited.

Description

technical field [0001] The invention relates to the technical field of rice planting, and specifically relates to a method for cultivating rice in an artificial light environment during the whole growth period. Background technique [0002] Rice is one of the most important food crops in my country, and the research on indoor rice cultivation in artificial climate is of great significance to rice production. Indoor cultivation of rice in an artificial climate requires a suitable light environment, and the use of suitable artificial light to grow rice can regulate the number of planting stubbles. It has environmental potential in the study of rice environmental stress response, disease and insect pest control, rice breeding, reproduction, improvement and germplasm resource renewal. control advantage. However, when growing rice indoors, the environmental parameters for planting still need to be studied and optimized. A suitable light environment is one of the key factors affe...
