"Sixteenpipe-beds(Fig. 1 and 2), two of a device for measuring evapotranspiration (Fig. 4 and 5), 16 sand pots (Fig. 7), and aditch-bed(Fig. 5) were established. These were devised to subirrigate by capillary movement of water or diluted liquid fertlizer throughwater-conducting pipesinwater-storage pipes, cylinders, containers, and a ditch. Sand and soil were used for media. Sumitomo Liquid Fertilizer No.2 (10-5-8) were diluted in water. With the device for measuring evapotranspiration, experiments were made on the adaptability of various materials for conductibity of water. Fine sand screened through plastic screen (1.1mm open spaces) was satisfactory. The sand pots were made for the purpose of conducting fertilizer tests, but the individual pots had greatly different evaporation rates due to microenvironmental factors, and fertilizer tests could not be done. The ditch-bed was good for raising seedlings. Although a ditch-bed can store rain water, capillary water from underground can not be utilized. Therefore, water may not be economically used. The C-type of pipe-beds used in the the eggplant culture are considered to be satisfactory for most crops. For root crops the D-type should be used. In weedy fields the B-type is better. And in soils where soil-borne diseases are problems the A-type can be advantageously used. It is considered that water-conducting pipes are made just to extrude from the water-storage pipes (11cm long) and spaced 10cm when inner diameter thereof is 13mm. Although the studies are on the exploratory stage, it is expected to be practical. The method of water and fertilizer application is not only effective and efficient for plant growth and saving labor but also not too expensive for constrution and operation and also durable.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/4565"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0370-4246"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250548"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u8fb2\u5b66\u90e8\u5b66\u8853\u5831\u544a"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "The Science Bulletin of the Faculty of Agriculture.
