Provided is a light emitting device that includes a light emitting element having a light emission peak wavelength ranging from 380 nm to 490 nm, and a fluorescent material excited by light from the light emitting element and emitting light having at a light emission peak wavelength ranging from 580 nm or more to less than 680 nm. The light emitting device emits light having a ratio R/B of a photon flux density R to a photon flux density B ranging from 2.0 to 4.0 and a ratio R/FR of the photon flux density R to a photon flux density FR ranging from 0.7 to 13.0, the photon flux density R being in a wavelength range of 620 nm or more and less than 700 nm, the photon flux density B being in a wavelength range of 380 nm or more and 490 nm or less, and the photon flux density FR being in a wavelength range of 700 nm or more and 780 nm or less.

The present invention relates to the use of specific active substances, alone or in combination, for controlling virus infections in plants and to a method for using said specific active substances for controlling said virus infections in the field of plant protection and the protection of materials.

A method for cultivating plants of the Asteraceae family, which promotes flower bud formation in the reproductive phase. A method for cultivating plants of the Asteraceae family, wherein the cultivation temperature in the reproductive phase is set lower by at least 5 C. than the cultivation temperature in the vegetative phase to promote flower bud formation in the reproductive phase.

The following invention is a system for protecting tall bamboo plants from winter weather. The system includes several improvements over existing plant covers. It uses a simple method involving a vertical funnel for covering bamboo. A two-piece funnel is clamped around the base of the bamboo. A long strip of fabric with hook and loop on both sides is connected to the bottom of the funnel. The funnel is then pulled by a rope to the top of the bamboo. The hook and loop is fastened around the bamboo while the funnel is raised. A wireless relay allows the funnel and sleeve to be remotely disconnected. For extra cold protection and aesthetic beauty, Christmas lights can easily be included inside the cover.

Provided is a binding machine used to erect a post and bind a stem or branch of a plant to the post to enable the stem or branch to maintain a desired posture during the cultivation of fruits, vegetables, or flowers or gardening. The binding machine is configured not to allow an operating lever to be moved down when a binding tape is hooked to a tape pulling needle to prevent an erroneous operation while the binding tape is being drawn out and configured to prevent an iron pin bundle from being loaded upside down onto an iron pin supply part and to prevent an iron pin push bar from arbitrarily escaping the iron pin supply part and being lost when the iron pin push bar is separated from the iron pin supply part.

System (1) for separating bulk-supplied plant-bulbs into a single-file stream of spaced plant-bulbs and a method for transporting and spacing objects. The system comprises a bulk-conveyor (2) for conveying a plurality of plant-bulbs as a bulk mass; a single-file vibration-trough (3) downstream of the bulk-conveyor, arranged to receive plant-bulbs from the bulk-conveyor and to further convey received plant-bulbs in single-file; a single-file conveyor (4) downstream of the single-file vibration-trough, arranged to receive plant-bulbs from the vibration-trough; wherein the bulk-conveyor has a discharge edge (21) and the single-file vibration-trough is longitudinally aligned substantially parallel to the discharge edge; wherein the vibration-trough is configured to progress the plant-bulbs at a first speed, wherein the single-file conveyor is configured to progress the plant-bulbs at a second speed, and wherein the second speed is higher than the first speed whereby during use plant-bulbs transferring from the vibration-trough to the single-file conveyor are spaced on the single-file conveyor.

A method for promoting growth and bioactive substances of Crepidiastrum denticulatum including performing a stress treatment on Crepidiastrum denticulatum during cultivation thereof, in which the stress treatment includes at least of applying visible light, drying, exposing to low temperature, irradiating ultraviolet rays, and applying a chemical elicitor.
