嘉南地區主要什糧作物施肥技術及生產潛力之測定

鄭耀輝 黃和炎

摘  要

選擇本區主要什糧產區,測定玉米(學甲、麻豆)、高粱(朴子)、落花生(東勢)及大豆(義竹)之生產潛力,以明瞭現行栽培技術與自然條件下生產潛力之差距。本項工作在68年度辦理,由什糧作物加強施肥推廣示範區內,隨機選取學甲、麻豆、朴子各10處,義竹、東勢、各5處進行。其方法分成3個處理:一、示範區-依土壤速測值推肥料用量。二、無磷區-不施磷肥外,氮鉀同處理一、。三、農家慣用區(對照)-依當地農家習慣施肥。經產量等調查結果發現:示範區產量優於慣用區;慣用區優於無磷區。施肥量氮鉀肥示範區與慣用區相近,而磷肥用量慣用區顯然比示範區為少。學甲、麻豆、義竹等農家現行栽培技術已相當水準,增產潛力較小;而朴子、東勢如施以正確的施肥方法,其增產潛力仍大。


Fertilization and Potential Yield of Various Up-land Crops in Chia-nan Area

Y. H. Cheng, H. Y. Huang

Summary

        To test the potential yield of corn (Shynejea, Matou), sorghum (Putzu), peanut (Tungshyh) and soybean (Yitzu) for understanding the difference of potential yield under culturing and natural condition, the study had been done at Shynejea (10), Matou (10), Yitzu (5) and Tungshyh(5) where fertilization had been demonstrated in 1979.  Three treatments as follows: 1. Demonstration plot-recommending the quantity of fertilizer depended on the soil analysis.  2. Without phosphate plot- the same as treatment 1.  Without phosphate.  3. Check plot – following the usual fertilizer by farmer.

        We got the result as the yield of demonstration plots was the highest, and that without phosphate plots was the lowest.  The quantity of phosphate at check plot was less than that at demonstration plot but the quantity of nitrogen was the same at both plots.  Because the cultural technique has raised to the level so the potential yield is small at Shynejea, Matou and Putzu, and if using the correct fertilization the potential yield is larger at Putzu and Tungshyh.
