Cultivation method for improving quality of fruits and beans produced from coffee trees in agricultural vinyl greenhouses

Abstract

To address the issue of quality deterioration due to the effects of ultraviolet rays in sunlight and high temperature when cultivating coffee trees in agricultural vinyl greenhouses to produce fruits and beans, in view of the disadvantages of conventional methods.SOLUTION: A carbon dioxide gas injection port is provided in the space between a shading sheet and coffee trees within an agricultural vinyl greenhouse to create a high-concentration carbon dioxide environment. Then, blue LED light is applied to a position corresponding to the height of the coffee trees.SELECTED DRAWING: Figure 1

Description

Technical Field

[0001] This invention relates to irradiating blue LEDs in a high-concentration carbon dioxide environment after reducing the intrusion of sunlight in a greenhouse with a light-shielding sheet or the like.

Background Art

[0002] In the conventional method, the fruits and beans of coffee trees cultivated in a greenhouse are affected by quality deterioration due to ultraviolet rays and high temperatures from sunlight.

Summary of the Invention

Problems to be Solved by the Invention

[0003] Prevent adverse effects such as ultraviolet rays and high temperatures from sunlight on coffee trees in the greenhouse. Means for Solving the Problems

[0004] This invention provides a light-shielding sheet or the like that reduces the intrusion of sunlight between the ceiling in the greenhouse and the coffee trees. Irradiate the coffee trees with colored LEDs such as blue between the light-shielding sheet or the like and the coffee trees. Increase the carbon dioxide concentration in the greenhouse with a liquefied carbon dioxide cylinder or a carbon dioxide generator. Effects of the Invention

[0005] According to this invention, by reducing the influence of sunlight in the greenhouse, it is possible to improve the yield and quality of fruits and beans obtained from coffee trees cultivated in the greenhouse.

Embodiments for Carrying Out the Invention

[0007] In the embodiment for carrying out this invention shown in FIG. 1, the light-shielding sheet 2 is provided between the ceiling of the greenhouse and the coffee trees. The colored LED 3 is provided with a light-shielding sheet between the coffee trees. The carbon dioxide injection port 4 is installed at a position where it can be injected from above the coffee trees.
