Abstract: | 植物營養診斷過去之遲遲未能全面推展,除了社會經濟因素外,(1)營養診斷基準之試驗依鋸欠缺及研究人員之拘泥於基準之探討,未能積極將已得試驗結果善加應用,(2)土壤、植体之分析以及分析結果之判釋效率不高,未能爭取時效,以廣得農民興趣,等亦甚重要。 其實葉片分析、營養診斷基準之試驗依鋸,除了構成植体之大量要素較難確定外,功能與植休內酵素活性有關之其他要素應可直接引用外國資料應用,蓋其受作物品種、氣候、栽培管理因素之影響較小,其臨界濃度或適宜濃度範圍之變異亦是較小,可以通用。大量要素之適宜濃度標準因受品種、氣候、栽培管理因素之影響較大,變異亦大。但若要等到肥料試驗之客觀分析,歸納出確切基準才應用,實嫌太遲,並且亦不符實際。應以既定基準出發,在實際診斷服務過程中依照個別狀況機動調整、再調整,才是較妥方法。 至於診斷效率之提高則可由:(l)高效能分析儀器之引進及分析自動化之加強,(2)營養診斷系統之發展,(3)診斷組織之加強;即基層服務單位、分析中心以及診斷研究單位之密切配台,等方面加以改進。 The factors hindering the popularity of leaf diagnosis in Taiwan have been assessed. A positive attitude of researchers towards unification of the searches on optimum nutrient criteria of leaves and its confirmation of applicability in practical diagnostic service rather than an ordi nary attitude of conservative researchers who conduct trials solely for the searches was emphasized. The necessity of raising diagnostic efficiency by 1) improving the analytical facility, 2) developing a computerized diagnosis informatio.n system, and 3) strengthening the system of researchers and extension workers was also emphasized. |
