摘要

為解決穴盤育苗之播種問題，本場已研製成一套簡易式蔬菜育苗播種一貫作業機。為提昇該機之播種精確度，本研究將其播種機構加以改良，以縮短落種口與穴盤間之距離，以減少種子掉落時之跳動情形。本播種機經過改良後，落種口與穴盤間之距離可縮短6 cm，經過組裝後，以甘藍種子作播種測試結果得知，每箱72格之穴盤，其播種率可達99.72%，缺播率為0.28%，每格播二粒者為0.42%；每箱128格之穴盤，其播種率亦可達99.38%，缺播率為0.62%，每格播二粒者亦僅0.70%。由本試驗結果得知，本機械經過改良後，其播種精確度可顯著提高。本機不僅可作為蔬菜育苗播種用，亦可作為穴盤葉菜類栽培用。

In order to solve the seeding problem of vegetable plug seedling production, a simple type automatic vegetable seeding machine was previously developed by the station. However, the seeding mechanism of the automatic seeding machine was improved again in this study for the purpose of increasing its seeding accuracy. After improvement by reducing the size of seeding mechanism, the distance between the seed dropping aperture to the seedling tray could reduce 6 cm. Therefore, the occurrence of the seed rebounding phenomenon during seed dropping was also decreased. The results of seeding tests with cabbage showed that the seeding accuracy on 72 cell tray could reach 99.72%, missing plant was only 0.28% and the No. of cell with two seeds was 0.42%, while the seeding accuracy on 128 cell tray could also reach 99.38%, missing plant was 0.62% and the No. of cell with two seeds was only 0.70%. The results indicated that after improvement, the seeding accuracy of the simple type automatic vegetable seeding machine was significantly increased. Therefore, this automatic seeding machine was not only very useful for plug seedling production, but also very pratical for growing leaf vegetables on seedling trays.
