中文摘要 | 本省專業化之蔬菜育苗中心及一般菜農已普遍地採用育苗箱培育菜苗,隨著蔬菜移植機之推廣,今後蔬菜大面積之育苗必將和水稻育苗方式一樣,完全走向育苗箱式之育苗法。然而到目前為止,蔬菜育苗箱之播種仍然依賴人工一粒一粒的播種,不僅工作效率低,且播種量不易控制。 本機械係睛真空吸力原理,利用針尖磨平之注射針作為種子吸附器,以一般家用之吸塵器作為真空泵浦,在適當壓力之控制下,即可精確的播種,每吸一次可播種一箱,且可使苗箱之每一方格僅播一粒種子。 使用本機播種甘藍及花椰菜時,可採用19號之種子吸附器(孔徑0.72mm),調整吸力為30mm Hg即可精確地播種,操作熟練時,每6秒鐘即可播種一箱,加以人工播種需3分半鐘始可播種一箱,因此採用本機播種之效率約較人工播種是35倍。 |
英文摘要 | In Taiwan, seedling boxes are commonly used by nursery centers and farmers to raise vegetable seedlings. It was estimated that raising vegetable seedlings on seedling boxes would become popular as well as raising rice seedlings in the near future due to the extension of vegetable transplanter. However, sowing vegetable seeds on seedling boxes by hand was not only labor-consuming but also inaccurate. In order to solve the sowing problem of seedling boxes, a vacuum seeder was developed in the Taoyuan station based on vacuum pickup principles. The seeder consisted of a number of changeable vacuum–operated nozzles and a vacuum pump. During operation, each of the nozzles could pick up one seed, and each operation could sow one box. The results of the tests showed that for precision sowing of cabbage and cauliflower seeds, nozzles of 0.72mm diameter (No. 19 hypodermic needles) and vacuum pressure of 30mm Hg were the best combination recommended. For a skilled operator, it would take only 6 seconds per box for sowing with this seeder, while it would take 3 and a half minutes for sowing with hand. |
