Means for Solving the Problems The present invention has the following configurations. 1. Soil for seed plants in which natural organic fibers or lightweight inorganic substances are added to the bran obtained when wheat is milled. 2. A growing floor formed by molding the above-mentioned soil into a pot shape, a mat shape or a bed shape. 3. 20 to 30 parts of water for 100 parts by weight of the above soil
A method for producing a growing bed, which comprises mixing 0 parts by weight, molding it into a pot shape, a mat shape or a bed shape and heating it to 50 to 100 ° C. 4. A growing method for growing a plant using the above-mentioned growing bed.

The soil for seed plants of the present invention is obtained by blending natural organic fibers or lightweight inorganic substances in the bran obtained when wheat is milled. The soil of the present invention has a high air ratio, excellent water permeability, water retention, inexpensive and excellent growth,
It is a soil for growing active roots and can be used as it is in pots, planters, etc., or as a soil conditioner.
The bran used in the present invention is a mixed product containing wheat rind as a main component, which is generated when wheat is milled, and is a residue of wheat milling. Examples of the natural organic fiber used in the present invention include natural organic fibers such as peat moss, coconut husk, and cellulose, and the mixing ratio thereof is 10 to 90% by weight, preferably 30 to 70% by weight. Examples of the lightweight inorganic material used in the present invention include lightweight inorganic materials such as vermiculite and pumice (foaming), and the mixing ratio thereof is 10 to 90% by weight, preferably 30 to 70% by weight. The soil of the present invention may be added with an inorganic substance such as a fertilizer, a pH adjuster, a fungicide, sand, borax, zeolite and calcium carbonate, if necessary.

The growing bed of the present invention is formed by shaping the above-mentioned soil into a pot shape, a mat shape or a bed shape, and more specifically, a round or square pot shape having a diameter or side of 2 to 10 cm and a thickness. 1-30 cm mat shape,
It is molded into a bed shape with one side of about 50 cm to 3 m. The growing bed can be more strongly solidified by using a water-soluble organic polymer compound such as starch or a solidifying agent such as clay in combination. The method for producing the growing bed is as follows. Water is mixed with the above-mentioned soil and charged into a mold made of paper, wood, metal, resin or fiber, and then heated to 50 to 100 ° C., and preferably 60 to Various methods, from small to large, can be obtained by heating to 80 ° C to obtain a growing bed, mixing the above-mentioned soil with water and press-molding or extruding, and adding water after molding to obtain a growing bed. It is possible to produce growing beds of different sizes. Seed plant cultivating soil of the present invention, a raising bed and a seedling raising method include raising seedlings of vegetables such as komatsuna and cucumber, raising seedlings such as strawberries, raising seeds of grains such as rice and wheat, raising grasses, raising grasses, raising young trees. It can be used in various ways.

[0016]

BEST MODE FOR CARRYING OUT THE INVENTION The growth floor is prepared by adding water to the bran,
It is obtained by making paste and drying. The reason for this is that wheat bran contains flour starch, and this starch is glued and becomes an adhesive to solidify the soil by drying.

EXAMPLES Next, examples will be described, but the present invention is not limited to these examples. The performance test of the present invention was conducted for the following items. Performance test of growing floor (1) Measurement of surface hardness of growing floor It was measured with a Kiya type hardness meter [model KHT-20]. The measurement is the load when the pressure test rod penetrates 4 mm from the surface of the material. The larger the measured value, the higher the surface hardness of the growing floor, and the better the shape retention when carried. (2) Measurement of underwater shape retention of growing floor Put 500 g of water in a 1 liter beaker and put the growing floor. Leave at room temperature and change water once a day. The thing which maintains the shape for one week shall be 7 days, and the thing which disintegrates in the middle shall describe the time until it disintegrates. The longer the measurement time, the better the growth floor because it does not collapse during plant growth. (3) Measurement of air ratio of growing floor It was measured with a soil three-phase meter [model DIK-1121]. The growth floor is placed in a cylindrical data room with a diameter of 5 cm, and the change in pressure is measured. Calculate the air and solid fractions. The higher the measured air ratio, the better the growth floor.

Growth test The test period is from November 6th, 1995 to November 16th.
It was carried out for 0 days. Regarding the test content, 20 seeds of Japanese mustard spinach were placed on the growth floor, and the seeds were thinly covered with soil as cover soil. Water is added to the height of the growing floor and germination is observed at room temperature. The test items were germination rate, growth rate and growth weight. (4) The germination rate is a percentage of the number of germinated seeds among 20 seeds. (5) The growth rate is a percentage of the number of 20 seeds that have grown to Futaba. (5) Growth weight is the weight of the total number of cut leaves (above the growth bed) grown on the last day of the test period. The higher the germination rate and the higher the growth rate,
Are better. Also, the higher the growth weight, the better.

Example 1 10 g of bran having an average particle diameter of 0.4 mm was mixed with 10 g of vermiculite [manufactured by Chisso Corp. V-2] to make a soil, to which 10 g of water was added and stirred by hand to obtain a diameter of 5 cm. Put the whole amount into the paper cylinder type and heat it in a 90 ° C oven for 5 hours.
