食材溯源之田間管理個案研究－以落葵施用不同有機肥料之效益分析

食材溯源不只是消費者對於農糧產品食用安心的訴求，更是對永續農業與環境保護的意義表露支持。本文以食材溯源於田間實務管理的個案研究，選擇落葵（Basella alba Linn.）為研究對象，以施用不同有機肥料對落葵生長性狀之影響研究，即是提出滿足消費者信任對食材溯源之研究。所使用之有機肥料區分為有機固體肥料（對照組）與有機液體酵素（試驗組）等二組，自播種至生長熟成耗時六週42天採收，以量測去根全株重量與去根全株長度，進行差異化分析研究，目的在鑑定施用此二種肥料，對於落葵生長之效益分析。試驗落葵種植農園位於臺灣苗栗縣。試驗組與對照組的試驗面積，各為90公分 × 200公分 × 2區塊，進行田間試驗。二組各播種200顆種子，42天熟成後隨機採收80株調查生產量。試驗資料以SPSS軟體進行平均數差異之描述性統計與獨立t檢定之研究方法分析。田間試驗結果顯示，使用有機液體酵素之試驗組，優於對照組有機固體肥料的生長，試驗組去根全株鮮重，較對照組重5.86 g（p≦0.001）；試驗組去根全株長度，較對照組長2.20 cm（p≦0.001）。此結果證明，田間管理添加有機液體酵素優於有機固體肥料，並有效提升有機栽培落葵之產能，以此提供農民做為田間管理效益提升之參考。

The food traceability is not only a consumer's demand for the safety of Agri-Food products, but also a support for sustainable agriculture and environmental protection. This is a case study on the food traceability from field practice management. Basella alba Linn. was selected as the research object, and the effect of applying different organic fertilizers on its growth traits was studied, and then the research on the food traceability to satisfy consumers' trust was proposed. The organic fertilizers used in this study were divided into solid fertilizers (control group) and liquid enzymes (experimental group).It took 42 days from sowing to maturity. After harvesting, the weight of the whole plant without roots and the length of the whole plant without roots were measured for differential analysis. The purpose was to identify the benefits of applying these two kinds of fertilizers to the growth of Basella alba Linn. The experimental Basella alba Linn. Planting farm is located in Miaoli County, Taiwan. The planting areas of the experimental group and the control group were 90 cm × 200 cm × 2 blocks each. 200 seeds were sown in each of the two groups, and 80 trees were randomly harvested after 42 days of ripening for production survey. The experimental data were analyzed by SPSS software for descriptive statistics and independent t test. The results showed that the growth of the test group using organic liquid enzymes was better than that of the control group with organic solid fertilizers. In terms of fresh weight of the whole plant without roots, the experimental group was 5.86 g heavier than the control group ( p≦0.001); In the length of the whole plant without roots, the experimental group was 2.20 cm longer than the control group ( p≦0.001). This result addresses that the addition of organic liquid enzymes in field management was superior to organic solid fertilizers, and could effectively increase the yield of organically cultivated Basella alba Linn. This found can provide farmers as a reference for improving the efficiency of field management.
