Description of the Related Art In order to efficiently cultivate plants and reduce cultivation labor, the soil is suitable for plant cultivation, and the soil contains abundant nutrients necessary for plant growth. It is necessary to meet the conditions such as supplying water necessary for the growth of plants. Therefore, when the soil in which the plant is cultivated has a soil quality such as clay and sand that is not suitable for plant cultivation, a soil improver is mixed into the soil,
BACKGROUND ART Conventionally, a method of improving soil quality suitable for cultivation or, when nutrients are insufficient, mixing fertilizer such as livestock dung into the soil to increase nutrients has been widely used.

い。However, although water is necessary for the normal germination and growth of plants, the above-mentioned soil conditioners and fertilizers generally have poor water absorption, and they are mixed in the soil. However, improvement in water retention can hardly be expected. Therefore, if the water supply to the soil is insufficient, the soil will be dried and the plant will not be able to absorb enough water for germination and growth, resulting in poor germination and growth. For this reason,
The water supply must be frequent, and the effort is large.
【０００４】本発明はこのような事情のもとになされた
ものであり、その目的は、保水性能が高く、植物の発芽

発芽・成育が助長される。[Function] The water supplied to the medium for plant cultivation absorbs and retains a large amount of water by the water absorbent resin, and this retained water gradually exudes into the culture soil as the culture soil dries, and further Water is absorbed. Moreover, since nutrients such as compost are abundantly contained in the culture soil, this nutrient is absorbed into the plant together with the water that has exuded into the culture soil, thereby promoting germination and growth of the plant.

効率的な栽培や栽培労力の軽減が図れる。Therefore, the water in the culture soil is not depleted for a long period of time, and sufficient water is given to the plants, so that the germination and growth of the plants are promoted, and the efficient cultivation of the plants is carried out. And the labor required for cultivation can be reduced.

行なったものである。First, in order to confirm the water retention of the medium according to the present invention, water is supplied to each of the test pot and the control product pot, and the weight of how much the increased water content due to this water supply is retained is measured. When tested by Table 2,
The results shown in are obtained. In this test, water was supplied only once at the start of the test, and no water was supplied during the test.
The water retention confirmation test after the lapse of days and after the lapse of 35 days was conducted in different periods from August 5 to August 10 and from August 29 to October 3, respectively.

る。[Table 2] As is clear from the results in Table 2, in the comparative test after 5 days from the start of the test, the test product had 87.5% (833.5%) of the increased water content (952.5 g) due to water supply.
The water content of g) is retained, which is considerably higher than 66.9% of the control product. In the comparative test after 35 days, the test product retained 5.7% (45.0 g) of the increased water content due to water supply (789.0 g), while the control product increased water content due to water supply ( 386.0 g) was all dried, and 227.0 g of the water originally contained in the culture soil at the start of the test was lost. From the above, it is understood that the water retention of the medium according to the present invention is dramatically superior to that of the conventional culture soil alone.

示すとおりである。Next, an example of actually cultivating Komatsuna using the medium for plant cultivation according to the present invention will be described. Six test pots and 6 control pots were prepared, and seeds of Komatsuna seeds were planted in each pot and water was supplied to the pots. It is shown.

おりである。[Table 3] The number of each pot at the number of days 0 in Table 3 shows the weight after water supply, but the total weight of each pot before water supply and the medium for plant cultivation is 1300 g, and water supply is only once at the start of cultivation. So, I haven't done any water supply after that. And
For each of the test product and the control product, the average value of the total weight of 6 pots was calculated every number of days elapsed (the test start date is 0), and the total weight of the pot and the plant cultivation medium was 13 from the average value.
The average value of the weight gain due to water supply was calculated by subtracting 00 g, and the water retention rate was calculated for each of the test product and the control product based on the following formula (1) from the average value of the weight gain. was gotten. The time-dependent changes in water retention of the test product and the control product are shown in FIG.

を少なくすることができる。[Table 4] As is clear from Table 4 and FIG. 1, in the test product using the medium for plant cultivation according to the present invention, the water retention rate is remarkably higher than that of the control product using only the conventional culture soil. It is shown that even when the medium for plant cultivation according to the present invention is used for cultivating a plant, the above-mentioned dramatically excellent water retention is maintained. Therefore, when the medium for plant cultivation according to the present invention is used, it is possible to reduce the frequency of water supply and to reduce the growth failure due to depletion of water.

できる。The total weight of Komatsuna grown in the test pot and the control pot was 36.5 g and 24.7 g, respectively, and converted to an average weight per pot of 6.1 g.
/ Pot, 4.1 g / pot, and the collected amount of the test product was about 1.5 times the collected amount of the control product. As can be seen from these results, when the medium for plant cultivation according to the present invention is used, the growth of Komatsuna can be expected to be dramatically improved as compared with the case where only the conventional culture soil is used.
