Method and system for plant culture

Abstract

The invention discloses a method and a system for plant culture. Through obtaining the illumination intensity of a light-supplementing light source for a plant and judging whether the illumination intensity is more than a first set value or not, the illumination intensity of the light source is regulated to be more than the first set value when the condition that the illumination intensity is more than the first set value is not met; through obtaining the frequency of the light source and judging whether the frequency of the light source meets that f is not less than 1Hz but is not more than 10KHz or not, when the condition that the f is not less than 1Hz but is not more than 10KHz is not met, the frequency f of the light source is regulated to meet that the f is not less than 1Hz but is not more than 10KHz; through obtaining the duty ratio of the light source and judging whether the duty ratio meets that D is not less than 50 percent but is not more than 90 percent or not, when the condition that the D is not less than 50 percent but is not more than 90 percent is not met, the duty ratio of the light source is regulated to meet that the D is not less than 50 percent but is not more than 90 percent. Through setting three parameters at the same time, the control on the plant culture is realized. By adopting the method and the system, which are provided by the invention, the chlorophyll content, the fresh weight, the dry weight and the leaf area of the plant are all improved to different extents; the power consumption is decreased to some extent; the electric-energy conversion efficiency is improved to some extent; therefore, the energy-saving and yield-increasing effects are achieved to different extents.

Description

technical field [0001] The invention relates to the field of plant cultivation, in particular to a plant cultivation method and system. Background technique [0002] In the process of agricultural development, as a system for plant cultivation, plant factories are a common form. Because of its advantages of not being limited by time and space, controllable environment, and reducing labor force, it has been widely used all over the world since its establishment in the 1950s. According to the different ways of light energy utilization, plant cultivation systems can be divided into full sunlight utilization type, artificial light utilization type (full control type), and both sunlight and artificial light utilization type. [0003] The biggest problem facing the plant cultivation system is its high construction cost, including equipment construction, artificial light source and operating cost of air conditioning system. According to reports, energy consumption costs account fo...
