Description

Light directing system for plant cultivation.
Background 5 The present invention relates to a light directing system to promote crop growth for a plant cultivation system wherein crop is arranged in line, and wherein a passageway extends along the line of crop.
Such a light directing system is known from US2986842A which relates to the growing of plants, more particularly, to increase of the solar radiation received by the 10 plants so as to regulate and increase the photosynthesis of these growing plants. The apparatus of US2986842A essentially comprises a reflecting structure and a supporting structure. However this apparatus renders in circumstances areas between pair of rows not or poorly passable for a machine or operator.
US2940219A relates to a means for promoting plant growth and has for its object 15 to provide a means for promoting plant growth by reflecting sunlight on to the rows of plants and directing sprinkled water on to the rows rather than between the same. A more specific object is to provide an improved means for promoting plant growth comprising a sheet to be placed between rows and having a highly reflective outer surface for reflecting the sun's rays on to the plant rows and so formed as to direct the 20 water on to the rows of plants. However this sheet placed between rows and so formed as to direct the water on to the rows of plants renders in circumstances areas between the rows not or poorly passable for a machine or operator.
Likewise, FR928023A discloses a removable waterproof and reflective element which is placed between the lines of crop and creates an extremely hot and humid 25 atmosphere favourable to vegetation, causing a remarkable precocity. However this reflective element which is placed between the lines of crop renders in circumstances areas between the lines of crop not or poorly passable for a machine or operator.
