PROBLEM TO BE SOLVED: To provide a sowing machine intended for solving such problems that when performing sowing or soil covering after a watering device waters a nursery cabinet, sowing or soil covering is performed in a condition that sprinkled water is accumulated without being absorbed, on the top of bed soil filled in a nursery cabinet, and seeds which are sown on the top of bed soil are apt to be shut between bed soil and cover soil together with accumulated water, so there is a fear that sown seeds cause oxygen deficiency and become bad in germination.SOLUTION: This sowing machine which sows on a nursery cabinet 2 has a transportation path 3 which transports the nursery cabinet 2 to one direction. The sowing machine has such constitution that a bed soil filling device 6 which fills bed soil in the nursery cabinet 2, a sowing device 7 which sows on the nursery cabinet 2, and a soil covering device 8 which covers soil on the nursery cabinet 2 are set in the order from the upper side of the transportation path 3 along the transportation path 3, while a watering device 29 which waters to the nursery cabinet 2 is set between the bed soil filling device 6 and the sowing device 7, or between the sowing device 7 and the soil covering device 8, and it is possible to change an interval from a watering position of the watering device to a sowing position of the sowing device 7 or a soil covering position of the soil covering device 8 in the next process.COPYRIGHT: (C)2010,JPO&INPIT【課題】 灌水装置が育苗器に灌水した後に播種又は覆土を行うとき、育苗器に詰めた床土の上面に灌水した水が吸水されずに溜まった状態で播種又は覆土され、床土の上面に播種された種子が溜まった水と共に床土と覆土の間に閉じ込められやすくなり、播種された種子が酸欠を起こし出芽不良となるおそれがある。【解決手段】 育苗器2に播種する播種機であって、前記育苗器2を一方向に搬送する搬送経路3を備え、該搬送経路3に沿って該搬送経路3の上手側から順に育苗器2に床土を詰める床土詰装置6と育苗器2に播種する播種装置7と育苗器2に覆土する覆土装置8とを設け、床土詰装置6と播種装置7の間又は播種装置7と覆土装置8の間に育苗器2に灌水する灌水装置29を設け、灌水装置の灌水位置から次工程の播種装置7の播種位置又は覆土装置8の覆土位置までの間隔を変更できる構成とした。【選択図】 図2
