為建構雜糧種子有機生產模式，本研究分別就品種篩選、種子採收調製及倉儲節能等方面進行探討。根據肥培試驗結果顯示，不同肥培處理對於9 個玉米參試品種之調查性狀表現具有不同程度之影響，其中參試品種1401 在不施肥處理下，其穗長、穗徑、脫實率、百粒重及單穗重等表現與慣行化肥施用處理者相比無明顯下降，具備作為有機適用品種之潛力。而就單株鮮重表現方面，因參試品種在不施肥處理下之表現均未達篩選標準 (444 g/株)，故尚無可供有機青割栽培直接利用之參試品種。在採收調製試驗部份，結果顯示不同機具在小麥採收作業效能上，水稻聯合收穫機在收穫率、排出損失率及破損率等方面之表現，均較雜糧聯合收穫機為佳，然其夾雜物率較高。就種子調製程序而言，與單一使用風選者相較，採篩盤及風選作業方式可有效提高種子潔淨度。在冷藏倉儲節能研究上，資料顯示冷凍機組運轉頻率及用電度數受大氣溫度變化直接影響，並以每日13 至17 時最高，17 時至隔日8 時為最低。
In order to establish an organic seed production system for grain crops, the three different parts of the production system including variety selection, seed harvesting and processing, and refrigerated warehouse energy efficiency are investigated in this study. The results of fertilization experiments show that the effects of different levels of fertilizer treatments on 9 varieties tested are different. Among these varieties, the ear length, ear diameter, shelling rate, 100-grain weight, and ear weight of variety 1401 in the condition without fertilizers do not decrease significantly compared to the one fertilized by chemical fertilizers conventionally, so the variety may have the potential as an organic variety. In terms of the fresh weight of single plant, there is no variety tested could be directly used for organic silage production because that all the varieties tested do not achieve the screening criteria (444 g/plant). In the harvesting and processing experiments of wheat, the results indicate that the efficiency of rice combine is better than the combine designed for grain crops in the aspect of threshing ratio, loss ratio, and broken ratio, but its impurity rate is higher. Considering the procedure of seed processing, the seed cleanliness would be improved efficiently by the utilization of sieve plates and wind selection compared to the one selected only by wind. In the research on refrigerated warehouse energy efficiency, the data shows that the operating frequency and energy consumption (kW·h) of refrigerating systems are affected directly by atmospheric temperature. The highest energy-consuming period is between 1 PM and 5 PM, and the lowest one is between 5 PM and 8 AM.
