| 中文摘要 | 本研究目的在於探討臺中區農業改良場新研發的四輪乘坐式油壓鑽孔機應用於梨園施用有機質肥料之作業效率,以及對於梨樹生長、葉片養分含量、土壤理化特性等之影響。試驗處理包括兩種施肥法(梨溝淺施法與鑽孔深施法)及兩種有機肥料(蔗渣木屑堆肥及牛羊糞堆肥),組合成四級處理。由連續兩年試驗結果顯示,使用四輪乘坐式油壓鑽孔機進行鑽孔深施有機質肥料的作業效率為使用中耕機進行梨溝淺施法之1.38倍。採用鑽孔深施處理之底土(20~40 cm)的土壤EC值、有機質含量、有效性磷及交換性鉀含量等土壤肥力特性較高,且可以降低土層的土壤硬度等特性。在梨樹採收期結果枝成熟葉片養分含量分析結果顯示,不同處理間無顯著性差異。由第二年高接梨果實產量調查結果顯示,鑽孔深施有機質肥料處理的果實產量較梨溝淺施有機質肥料處理可高約5~8%。 |
| 英文摘要 | The objective of this research was to evaluate the application efficiency and the effects, the fruit qualities of pear, leaf nutrient contents and soil characteristics at pear orchard on the application of organic fertilizer by using new self-propelled hydraulic digger. The new self-propelled hydraulic digger was developed from TaichungDARES. Two-year field experiment was conducted with two kinds of application methods (shallow furrow by using plough and digging cylindrical hole by using new self-propelled hydraulic digger) and with two kinds of organic fertilizer (bagase-sawdust compost and cattle- goat waste manure). The result showed that the efficiency of application organic fertilizer with new self-propelled hydraulic digger was higher than that with plough by 1.38 time. The EC, OM, available P and exchangeable K contents of sub-soil (20-40 cm) were higher on the treatment with new self-propelled hydraulic digger; the sub-soil hardness was reduced on the same treatment. No clear behavior of nutrient concentrations in leaf (N, P, K, Ca and Mg) was detected in relation to treatments. The fruit yield of grafted pear on the application of organic fertilizer with new self-propelled hydraulic digger was higher than that on the treatment with plough by 5-8% during the second year of cultivation. |
