中文摘要 | 本試驗目的在探討不同有機質肥料生雞糞、豬糞堆肥及化學肥料對山藥生育及產量之影響,以提供農民肥培之參考。試驗結果顯示:施用豬糞堆肥可提高土壤pH值0.1-0.2單位不等,EC值亦提高0.01-0.02dS/m,土壤有機質含量則以施用豬糞堆肥10t/ha處理為最高,較對照化肥區增加0.2-0.3%,葉片各元素養分含量以施用豬糞堆肥較生雞糞及化肥區為高,山藥種薯萌芽率及塊莖生長情形,以施用豬糞堆肥為較佳,而現莖產量則以施用豬糞堆肥5t/ha之38.3t/ha為最佳,較化肥對照區之31.1t/ha增重7.2t/ha,增產率23.1%,其餘施用生雞糞及豬糞堆肥10t/ha,亦則分別較對照化肥區增產19.9%及15.8%。 |
英文摘要 | The experiment was conducted at Shin-Lin district of Taipei City to evaluate the effect of applying different organic fertilizers VS. chemical fertilizers on the growth and yield of yam plants (Dioscorea spp.) The results of our experiments indicated that application of hog compost could raise the soil pH value from 0.1 to 0.2 units as well as the EC value by 0.01 to 0.02 dS/m. The organic matter content of soil that received 10 t/ha of hog compost was the highest among the treatments, which was 0.2-0.3 % higher than that of chemical fertilizer treatment (N-P20cK20= 90-60-120 kg/ha). The nutrients content of yam leaves that sampled from hog compost treatment was higher than those of raw chicken manure and chemical fertilizer treatments. The germination rate and the growth of the yam tubers was better in the hog compost treatment. In terms of the tuber production, the hog compost treatment (5 t/ha) gave the highest yield at 38.3 t/ha, which was 7.2 t/ha (23.1 %) higher than that of chemical fertilizer treatment. The yield of raw chicken manure and hog compost (10t/ha) treatments were 19.9 % and 15.8 % higher than that of chemical fertilizer treatment. |
