A method of rice cultivation based on LED plant lights without natural light

Abstract

A rice breeding technology based on an LED plant lamp in the absence of natural light is characterized in that the irradiation time of the LED plant lamp is 10 h every day, the period is more than 120 days, and different ratios and illumination intensity of red and blue light of the LED plant lamp at rice breeding stages are as follows: at the seedling stage, the ratio of red light to blue light of the LED plant lamp is 5:1 and the illumination intensity is 130 mu mol / (m<2>*s); at the seedling tillering stage, the ratio of red light to blue light of the LED plant lamp is 7:1 and the illumination intensity is 180 mu mol / (m<2>*s); at the young ear developmental stage, the ratio of red light to blue light of the LED plant lamp is 7:1 and the illumination intensity is 180 mu mol / (m<2>*s); at the flowering and fruiting stage, the ratio of red light to blue light of the LED plant lamp is 7:1 and the illumination intensity is 150 mu mol / (m<2>*s). The rice breeding technology has the benefits that the LED plant lamp simulates the sunlight and rice can be bred indoors throughout the year; the survival rate can reach 99%; the utilization rate of unit land, the output rate and the economic benefit are increased, and order-oriented and factory production can be met; a feasible way is explored for crop production adopting the factory mode in areas lacking land resources; safety production of grain can be realized.

Description

technical field [0001] The invention belongs to the field of plant cultivation, and in particular discloses a rice cultivation method based on LED plant lights without natural light Background technique [0002] Rice is one of the three major crops in the world, and nearly half of the world's population uses rice as a staple food. With the increase of the world's population and the improvement of people's living standards, the demand for rice is also increasing. However, because rice is a sun-loving and temperature-loving crop, it requires high light and temperature. Therefore, the cultivation of rice in alpine regions and long-term rainy and less sunny regions or spaces is greatly restricted. [0003] Agricultural science and technology workers and rice growers at home and abroad have tried to use geothermal heating for rice planting and adopt fluorescent lamps, incandescent lamps, high-pressure mercury lamps, etc. to keep warm and supplement light to make up for the lack ...

AI Technical Summary

Problems solved by technology

However, in the spectrum of these lamps, there are very few wavelengths of light that can enable plants to produce photosynthesis, so the light efficiency is low and the energy consumption is large, which cannot meet the needs of rice seedlings.

Continuous rainy days will inevitably lead to low survival rate and poor quality of rice
