在日本西南温暖多雨地带的干草生产,常受天气的影响而只能在盛夏的持续晴天里进行,但在水田地里由于土壤不象旱田那样干燥,所以即使在夏季也难以用割后就地晾晒的办法获得优质干草。为此,提出一种利用太阳能和低成本而随时调制干草的办法,也就是下述的利用塑料大棚的干燥设备。它是把原料草装在大棚里,棚内暖空气从草中通过的办法制成干草。 Dry grass production in the warm and rainy southwest of Japan is often affected by the weather and can only be carried out in the midsummer, but in the paddy fields, the soil is not as dry as the dry fields, making it difficult to cut the ground even in summer Dry the way to get quality hay. To this end, proposed a way to use solar energy and low cost at any time to adjust the hay, which is the following use of plastic shed drying equipment. It is the raw material installed in the greenhouse grass, greenhouse warm air from the grass through the way made of hay.
