中文摘要 | 目前國內水耕蔬菜栽培(Dynamic Root Floating System, DRF system)是以海棉做為苗床與成苗後移植於栽培床之固定介質,播種時必需將種子逐一播入海棉中,作業速度緩慢,在整體生產過程中已形成一瓶頸,本場為改善此一狀況,並考慮農民每天所需作業量,經研製完成頂桿式與撥桿式播種器各一種,可一次完成一片海棉共96小格之播種工作。 頂桿式播種器利用一具有96支頂桿之頂桿組將種子強制推送進入海棉中;完成播種。種子定位及數量控制分別由頂桿長度與種子量控制板來決定。其播種深度容易控制,每片海棉播種時間約一分鐘,但播種給小種子時,易將種子壓碎,影響發芽率,且每組頂桿所適用種子大小範圍有限,對所播之種子大小具選擇性。 撥桿式播種器採用一組撥桿,利用腳踏板操作連桿來帶撥桿,使撥桿上的塑膠撥片向下壓迫海棉,將海棉間隙強制分開,讓種子落入海棉間隙中,再鬆開撥片使海棉閉合,完成播種,黃作速度較快,每片海棉播種時間約30秒。對不同大約的種子,只需更換種子量控制板即可,但播種深度不易控制,影響發芽率。 |
英文摘要 | At the present time sponge are most popularly used for seedbed for hydroponics in Taiwan. As the seeds are usually put into the sponge by hand piece by piece, it is very slow or very low in efficiency. In order to overcome this seed sowing problem, two prototypes of seeders were developed in Taichung District Agricultural Improvement Station as follows: 1. Push-rod type seeder: This type of seeder use a push-rod set to push the seed into the sponge and deposit the seed in an acceptable position. Its seeding ability is about 1 min./piece of sponge. 2. Separate-blade type: This type of seeder use a plastic separate-blade to separate the sponge and let the seeds drop into the gaps. Its seeding ability is about 30 sec/piece of sponge. |
