Improvement and Localization on Environmental Control System of Enclosed Broiler Houses

加入世界貿易組織( WTO )是我國勢在必行的政策, 對於台灣地區的整體農業必將造成極大的衝擊.肉雞飼育業者育在強大的進口壓力下自強圖存, 唯有設法降低成本一途.引進密閉式籠飼雞舍, 為台灣的肉雞業者帶來新的契機.此種自動化的雞舍在歐洲裝設成果優良, 由於其環控技術適用於溫帶氣候, 在亞熱帶的台灣是否有同樣的效果? 本研究擬利用於台南欣達牧場及嘉義新全一牧場之密閉式環控籠飼雞舍取得之溫度與溼度紀錄, 並分析雞舍的作業環境條件及肉雞飼育結果, 配合理論分析, 建立環控策略之最佳模式, 針對不同型狀之擾流板及強制風扇評估其經濟效益.利用座談會來了解業者之問題與需求, 建立雙向溝通之聯絡網路, 結合經驗與理論來落實密閉式環控籠飼肉雞舍環控系統本土化之改良.以便成為台灣地區養雞業者可以選用的生產利器.To enroll the WTO ( World Trade Organization )is the strict policy for Taiwan government.This would impact the entire agriculture in Taiwan region.The broiler farmers struggle to survive in facing the huge pressure of importing.The only way would be to lower the cost as possible as they could.Importing the enclosed cage-feeding house brought some hope for the broiler farmers in Taiwan.This type of automatic controlled broiler house located in Europe and having performed well.However, the environment control technique was developed and applied in the warm region of the world.Would it be working properly in the subtropical region as well? This project, thus, will try to record some data in both Hsingda and Hsing-Chyu-Yi farms located in Tainan and Jiayi County, Taiwan, respectively.Both broiler farms have installed enclosed cage-feeding houses.Temperature and moisture will be recorded in both farms.The operating environment in the broiler houses and growth results associated with theoretical analysis will be involved to establish the optimal environment control model.And, it will be evaluated for the economic availability using various disturbing boards and electrical fans in the house.There will be several conversaziones held to learn the farmer's demand and establish two-way communication network as well.It works with experience and theory to settle the enclosed cage-feeding broiler house and localize the control system so that this type would be an alternative house for broiler farmer in Taiwan

Electrostatic Crop Spraying Device Used in Green House

至目前為止,農藥灑佈仍是防治作物病蟲害 最有效的方式.但傳統的施藥方法,可能只有 20% 的農藥被有效利用,其餘皆因飄移或流失而被 浪費,造成財物損失及環境污染.研究成果顯示: 將高電壓(4.0~ 35KV,DC) 低電流(10.mu.A 以下)的靜 電噴灑技術用於農藥灑佈作業,可以增加農藥 對作物植株的附著率,減少霧粒飄浮的作用,可 增加藥效,因而降低農藥用量,節省成本並有助 於環境保育. 國內目前正推行農業自動化政策,許多精緻作物皆置於溫室或棚架內種植生產, 由於栽培環境日趨密閉,設施內飄移的農藥極 易累積,對環境與工作者皆構成危害.既然靜電 噴藥系統可降低農藥用量,則其必然有助於減 緩農業設施內的藥害危機.目前國內鑽研靜電 噴藥的專家甚少,國外的研究多以開放田區為 主,且其所用之設備成本頗高.本計畫因而擬以 下列兩項為執行目的:(1)證明靜電噴藥系統可 提升農業設施內之施藥效果,減少藥害.(2)研究 開發廉價的靜電產生裝置,以降低靜電噴藥系 統的設備成本

Study of the Application and Loss Area Evaluation from Natural Disaster Using Satellite Image-Example on Forest Fire

本計畫係針對無法避免的森林火災，利用衛星影像進行對於災害的成因之探討、損失面積的推估、建立推估模式、與提供即時救災機制等作初步的分析與評估，期能對台灣地區的森林火災損失提供初步的推估模式，同時為將來防災救災機制提供使用衛星影像的可行性建議。衛星影像與地理資訊系統均將在此計畫中使用，透過台灣中部地區的森林歷史資料的參考，輔以衛星影像的套疊，加上小部分現場量測，將災害損失推估做一比較與評估，期能得到一可行之推估模式，對於未來的災害損失提供一方便有效的管道。The project is mainly focused on the inescapable disaster, forest fire. Satellite image will be applied on the preliminary study and evaluation of the discussion of disaster causes, damage area estimation, establishing the estimating model for loss area, and applying real time system for rescue work. Hopefully, this project could provide a basic estimating model for the forest fire damage area in Taiwan as well. There will be possibly providing a valid suggestion using satellite image for rescue work. Satellite image and GIS will be used in the project to overlap both information and check with some field measurement in the same area to check the validity of the estimating model. Thus, a valid estimating model for disaster area is expected. This model would provide a convenient and efficient way to estimate the real loss after disaster happened as well
