草苺健康種苗隔離設施生產整合管理技術

本試驗研究於農業試驗所現有半封閉式開頂溫室為種苗量產之基礎運作平台，以溫室正壓送風暨環境隔離系統之技術、水質淨化處理和介質滅菌處理，利用種苗繁殖場無病毒之原種苗，並利用養液供水降溫維持體系，可將草苺生長的根溫控在28-31℃，再結合低農藥之病蟲害監測管理等技術之整合與運用，已建立草苺健康種苗生產環境整合管理體系，供草苺種苗產業之利用。隔離設施內106 年三個草苺品種在苗株生長期之EC 在夏季8 月17 日到11 月30 日EC 調控在0.4-0.7 之間，草苺種苗生長因在高溫的夏季繁殖，病蟲害發生頻率高且易有生理障礙現象，栽培介質供給的養分(EC) 不需過多，可避免苗株生長過盛而提早老化。另pH 三個草苺品種在苗株生長期之pH 範圍在4.5-6.0 間呈弱酸性，維持在草苺適合生長的弱酸性。三個品種母株之葉片數、走莖數和蔓苗數如圖所顯示，葉片數以香水和芳玉最多可達60-67 片，走莖數以豐香較少在10 以下，芳玉的走莖數和蔓苗株數量最多可達17 條、54 株，其次為香水，豐香最少。 Facility experiments were conducted in the existing semi-enclosed greenhouse of Taiwan Agricultural Research Institute, which is the basic operation platform for the production of strawberry healthy seedlings. The healthy seedlings without virus and pathogens of Taoyuan No.1, Fangyu and aroma were based on the technology of greenhouse positive pressure air supply and high-density isolation system, irrigation purification treatment and medium sterilization treatment from August 17 to November 30 2017. When seedlings production, the concentration of the nutrient solution was control that the EC is maintained at 0.4-0.7 m S cm-1 and the pH is maintained at a weak acidity of 4.5-6.0. The leaf number per plant was the highest in aroma (67), followed by Fangyu (62), the lowest is Taoyuan No.1 (28), the runner and seedling per plant was the highest in Fangyu (17 and 54), the lowest is Taoyuan No.1 ( 6 and 39).
