[0059] The first embodiment is a field where crops are to be planted is covered with a light reflective sheet or a fluorescent emissive net or a fluorescent emissive sheet as the above-mentioned light reflective material, and the above-mentioned fluorescent emission is arranged in a manner to cover the crops. Sexual mesh or the method of the above-mentioned fluorescent emissive sheet, will refer to figure 2 schematic diagram for illustration.

[0060] figure 2 (a) is an example of combining a fluorescent emissive net as a material for covering crops and a light reflective sheet as a material for covering the field, figure 2 (b) is an example combining a fluorescent emissive net as a material for covering crops and a fluorescent emissive sheet as a material for covering the field, figure 2 (c) is an example in which a fluorescent emissive net is used as a material to cover crops, and a light reflective sheet and a fluorescent emissive sheet are used as a material to cover...

[0200] (Cultivation experiment of cherry white radish in the open field using the combination of fluorescent emissive net and fluorescent emissive sheet)

[0201] On a field in the Nishiyama area of ​​Miyagawa, Chino City, Nagano Prefecture, four plots (hereinafter referred to as ridge A, ridge B, ridge C, and ridge D) were prepared at intervals of 140 cm or 200 cm, about 120 cm from east to west, Cherry white radish was cultivated in the open field on a ridge of about 90 cm in the north-south direction. The cultivation time was 25 days from May 28, 2008 to June 21, 2008. During this period, the average temperature was 18.0°C, the average sunshine duration was 5.9 hours, and the cumulative value of incident light was 114.3kWh / m 2 .

[0202] The cultivation test was carried out by digging holes of about 3 cm x about 3 cm in size at twenty-four places at intervals of about 18 cm. In addition, a white ground covering sheet (hereinafter also referred to as "white plas...

[0209] (cultivation test of cherry radish)

[0210]On the campus of Suwa Tokyo University of Science in Chino City, Nagano Prefecture, a cultivation experiment of Japanese cherry radish was carried out during 28 days from June 3 to June 30, 2009. During this period, the average atmospheric temperature was 23.0°C, the average sunshine duration was 6.1 hours, and the cumulative value of incident light was 105Wh / m 2 .

[0211] Eight planting boxes (called planting boxes A, B, C, D, E, F, G, H) with a width of about 50 cm, a length of about 120 cm, and a height of about 50 cm were prepared for the cultivation test, and fluorescent emission was used as agricultural materials. Sexual net B (mesh: about 0.5cm × 0.5cm, porosity: about 40%, also called fluorescent net B), fluorescent emissive sheet S (also called fluorescent sheet S) and the same materials as those used in Example 1 Light reflective sheeting (also known as white mulch).

Abstract

Provided is a farm crop cultivation method comprising using a fluorescent emitting material for activating the photosynthesis of a farm crop, whereby the crop weight can be increased or the crop growth can be quickened to thereby establish a high cultivation efficiency with little variation in crop quality.  Also provided is a farm crop cultivation method using a fluorescent emitting material, whereby the sugar concentration or the like of a crop can be elevated and the content of a component such as lycopene contained in vegetables or fruits, for example, tomato, watermelon or pink grapefruit can be increased. A farm crop cultivation method which comprises using, as a material for farm crop cultivation, a fluorescent emitting net and a fluorescent emitting sheet either alone or as a combination thereof, or a combination of a light reflective material with a fluorescent emitting net and / or a fluorescent emitting sheet, wherein the material for farm crop cultivation is located in such manner that, under light irradiation, the farm crop can be irradiated from multiple directions by the fluorescent light emitted from the fluorescent emitting net or fluorescent emitting sheet to thereby promote photosynthesis.

Description

technical field [0001] The present invention relates to methods of growing crops using fluorescent emissive materials and materials therefor. Background technique [0002] Recently, in order to achieve a stable supply of agricultural products such as vegetables, the construction of plant factories for setting up factories for growing vegetables using light-emitting diodes and the like as light sources is in full swing. Such plant factory construction uses light-emitting diodes that irradiate light in a wavelength range that contributes to photosynthesis of plants, etc., to achieve planned cultivation. [0003] However, although this method can carry out planned cultivation, on the other hand, it consumes a large amount of electricity for cultivation, and has a great impact on environmental and energy issues such as global warming and the depletion of fossil fuels. People are worried. [0004] In addition, in open field cultivation, etc., pesticides are usually sprayed in o...
