Problems solved by technology

The domestic plant light source market has developed rapidly in recent years. Most LED manufacturers have not done in-depth research on the high-efficiency light environment of crops in different periods. The conventional mode is to use visible light continuous broadband spectrum LED equipment as plant light sources. The use of ambient light intensity, use time and other environmental factors has not set a range, which leads to low absorption and utilization of light energy by plants, resulting in a waste of energy

Abstract

The invention relates to the technical field of plant cultivation, in particular to a light environment regulation and control method for promoting growth of cucumbers. The light environment regulation and control method for promoting growth of the cucumbers in each growth period comprises the step of providing an artificial light source for growing cucumber seedlings so as to promote the growth of the cucumber seedlings. The light environment regulation and control method for promoting growth of the cucumbers in each growth period has the beneficial effects that light environment parameters suitable for the growth of the cucumbers are regulated in the growth process of the cucumbers in the growth periods, an optimal light supplementing scheme is provided for plants, the whole growth period from sowing germination to fruiting harvesting of the cucumbers is covered, the light energy absorption rate and utilization rate of the cucumbers are improved, electric energy is promoted to be converted into biochemical energy of cucumbers, the seedling strengthening rate and disease resistance of cucumber seedlings in winter or in a light-deficient environment are improved, early flowering is promoted, and the yield and quality of the cucumbers are improved.

Description

technical field [0001] The invention relates to the technical field of plant cultivation, in particular to a light environment regulation method for promoting cucumber growth. Background technique [0002] Light is closely related to the growth of crops. Capturing light energy to the greatest extent and giving full play to the potential of plant photosynthesis will be directly related to the benefits of agricultural production. In recent years, in order to meet the market demand, greenhouses are widely used to produce off-season flowers, fruits, vegetables, etc. Due to the short sunshine time in winter and spring, or the lack of sunshine such as continuous smog or rainy and snowy weather, the growth of crops is limited, and the growth rate is limited. The period is longer and the output is reduced, so it is urgent to supplement the light with artificial light sources. [0003] Plant light source is a device that uses artificial light sources to make up for insufficient sun...
