発明の名称 (英語) NUTRIENT LIQUID CULTIVATION METHOD FOR CULTIVATED PLANT, AND CULTURE SOLUTION FOR NUTRIENT LIQUID CULTIVATION NEW
発明の概要(英語) The present invention is a method for cultivating during the period from seeding to harvest using a culture liquid that includes the fertilizer components necessary for the maturation of a plant body. The method is characterized in that, when the abovementioned period is divided into a germination period in which a seedling-raising device is used for cultivation from seeding to germination, a seedling-raising period in which the seedling-raising device is used for cultivation until a seedling that has germinated at the seedling-raising device has grown to a prescribed size, and a maturation period in which the seedling that has been grown to the prescribed size is transplanted from the seedling-raising device to a maturation device and cultivated until being harvested from the maturation device, a seedling-raising culture solution that has a magnesium ion concentration of 24–120 ppm and a nitrate nitrogen concentration of 4–50 ppm is used during the seedling-raising period, or a maturation culture solution that has a magnesium ion concentration of 48–120 ppm and a nitrate nitrogen concentration of 150–200 ppm is used during the maturation period.
従来技術、競合技術の概要(英語) BACKGROUND ART
Magnesium, (ribosomal particle association) protein synthesis, DNA synthesis, the synthesized RNA, 300 to modulate the activity of one or more enzymes, ATP and stabilization of the elements involved, in addition, the constituent elements of chlorophyll and the like, required to support the life activities of element has been known.
Plants, cell division parts of the stems shoot meristem tissue located on the top and therefore, high in order to maintain the activity of cell division, are supplied at a relatively high concentration of magnesium to the tissue needs to be. In particular, DNA polymerase is directly related to the cell division, a relatively high concentration of the catalytic activity that requires a magnesium ion is known (for reference, Taq DNA polymerase activity of the catalyst required for the magnesium of 4mm (=96 PPM) the optimal concentration). Therefore, the top of the stem to shoot meristem and if there is insufficient supply of magnesium, cell division rate slows down, and thus the growth rate of an individual plant is reduced. On the other hand, the tissue if the magnesium sufficiently supplied, the growth rate of the individual plant is increased.
Magnesium is absorbed by the root. Most of the magnesium is absorbed by the roots, stem and root meristem tissue Meristematiccells the top of the direct delivery is not, first, the flow proceeds to the leaf by evaporation, then, the top of the stem on a stream of the tube screen shoot meristem and supplied to the tissue. Sieve pipe flow from the lower side to the high concentration of solute for flow, meristem tissue (sink side) than the magnesium concentration is required, comprises a supply side (source side) is higher than the magnesium concentration is required. That is, high (and thus the faster the growth rate) of the active cell division in order to maintain, the sink and source side of the magnesium concentration drop is required.
Plants such as flowers or vegetables of the cultivation method of liquid fertilizer to one of (for example Patent Document 1) is grown. Cultivated culture liquid fertilizer formulation is used, the prescribed course gardening, Yamazaki prescription, the prescription is the house by Otsuka A, both the formulation of these compositions, the growth of plants is essential for the three elements (nitrogen, phosphoric acid, potassium) as the center, depending on the type of target plants are combined to form an appropriate fertilizer component. Magnesium, due to the fact that greatly contribute to the growth of a plant, then the three elements included in the formulation of the culture medium is one of many fertilizer component.
Each formulation of the composition of the fertilizer component, components of each fertilizer plants such as the analysis result and the rate of absorption of the reference from the root, and are determined empirically, it is confirmed that the normal growth of the composition. In particular, the essential three elements and nitrogen, phosphoric acid, potassium, various types of plant fertilizer long been used as a component. And the nutrient solution cultivation between the service provider, a traditional prescription on experience and the best formulation, other formulations that is not susceptible to a misconception to try out for a strong, conventional culture without review the prescription, is continuously used in certain countries.
