The wood picked out in the mountains has many left things. As for the quantity of thinning materials felling in Shinshiro-city, Aichi of 2011, in 38,543㎥; inner; non-use is 22,000㎥, and, as for the availability, it is to around 44%. The introduction of the firewood stove (brand name Gronta) is considered as the countermeasure. When this puts three logs of 20cm in diameter (100cm in length), It burn more than eight hours, and a combustion calorie is up to 40,000kcal/ 1hour and is equal to a heavy oil boiler 150 type. It is thought that it leads to the utilization of local resources if I use this thinning materials as a thermal energy source of the horticulture and inspects the utility.

The LED such as low fever, the low power consumption is characteristic, and can expect photosynthesis promotion by the proximity irradiation. Furthermore, it is thought that irradiating it with light under the night stable temperature, humidity, the carbon dioxide density contributes to productivity improvement, but there are really few inspected examples. Therefore, using LED of the white red mixture, I irradiate proximity at irradiation distance of approximately 10cm than a plant body and confirm influence to give to the growth of the plant and examine the utility.

Introduction of Small-flowered chrysanthemum cultivation is considered as an item without the birds and beasts damage in mountainous regions, and the cultivation spreads. As a saving of labor technology of the cutting and planting, the purpose of the introduction of the direct planting of the planting unrooted cuttings technology of the bare ground time, a method (vinyl, poly, cheesecloth, covering method) of the planting unrooted cuttings ,influence on establishment by the difference in cultivated variety examine growth, influence on flowering afterwards.
