Abstract
土壤添加物可調整農田土壤的物理、化學及生物性質，藉由增加有機質含量改善土壤通氣性、補充作物所需微量元素、增加根圈微生物族群數量及多樣性，減緩植物病害對作物的負面影響，進而增加作物產量。本研究針對市售土壤添加物進行篩選，以溫室盆缽試驗與苦瓜萎凋病病田的田間小區試驗，評估土壤添加物對苦瓜萎凋病的影響。溫室試驗中，發現處理棕櫚灰、海鳥磷鈣、菜籽粕的苦瓜罹病率，較對照組分別降低 46.9%、34.3% 及 40.6%。而田間小區試驗結果發現對照組苦瓜於定植後第 25 天即開始發病，隨病程發展罹病率逐漸增加至72.2%，12 株苦瓜總產量僅有 4.1 公斤。處理組苦瓜於定植後第 53 天開始發病，隨病程發展罹病率僅增加至 38.9%，12 株苦瓜總產量共有 53.1 公斤。因此，棕櫚灰補充鉀肥與鈣肥促進苦瓜根系發展，而減緩病害發展速度。
Soil amendments can adjust the physical, chemical, and biological properties of agricultural soil. Those re-use of organic wastes improve soil aeration, replenish micronutrients, increase the quantity and diversity of root zone microorganisms, and suppress plant pathogens. This study tested commercially available soil amendments. To evaluate the effect on bitter gourd Fusarium wilt, we designed greenhouse pot experiment and field trials. In the greenhouse, the disease severity of bitter gourd treated with palm ash, seabird guano phosphate, and rapeseed meal was reduced 46.9%, 34.4%, and 40.6%, respectively, compared to the mock control. In the Ligang township field trials, bitter gourd Fusarium wilt symptoms of mock control showed on 25 day and bitter gourd of treatment showed on 53day. During 89-136 day, disease severity of bitter gourd Fusarium wilt increased to 72.2%, and total yield was 4.1kg/12 bitter gourd. Disease severity of treatment bitter gourd increased to 38.9%, and total yield was 53.1kg/12 bitter gourd. Therefore, soil amendments such as palm ash can supplement potassium and calcium fertilizers, promote bitter gourd root development, and slow down plant disease progression.
