中文摘要 | 有機質肥料是重要的肥田物質,不同的農業廢棄物所製得之有機質肥料性質不 同。本研究之目的探討在溫室條件下栽培短生長期之葉菜,長時期連用同一種有機質 肥料對土壤一般化學性質與土壤氮與磷組成的影響,作為肥料施用之參考。共有6 種 處理,即牛糞堆肥、豬糞堆肥、雞糞堆肥、大豆粕、豌豆苗殘體堆肥與輪施處理(牛 糞堆肥-豌豆苗殘體堆肥-豬糞堆肥-大豆粕-雞糞堆肥依次輪流施用),每處理4 重複,採逢機完全區集設計。經4 年栽培25 作葉菜後,採取土壤分析其一般性質及 以Bremner 的方法將氮劃分,以Sui 和Thompson 之續列萃取法將磷劃分。結果顯示 連續施用相同的有機質肥料,對土壤性質、氮與磷組成分均造成顯著影響。牛糞堆肥、 大豆粕與豌豆苗殘體堆肥使土壤pH 值下降,5 種有機質肥料均使土壤中的無機態氮、 有效磷與鉀累積至極高量,且超過一般作物栽培所需之有效養分量。連用大豆粕,無 法增加土壤有機質與總氮,且有明顯的促發反應而減少之,輪流施用不同的有機質肥 料,使土壤綜合表現各種有機質肥料之特性,是較理想的選擇。但是,施肥前之土壤 診斷是非常重要,否則將導致土壤無法用於作物生產。不同的有機質肥料長時間施用 的結果,不但改變土壤中氮與磷各劃份濃度且改變其佔總氮或總磷的比例之高低順 序。 |
英文摘要 | The organic fertilizer is an important material for fertilizing the soil. Organic fertilizers which are composted from different organic sources show different effects on soils and plants after applying to the soils. The objective of this study was to evaluate the effects of different fertilizers on the different fractions of soil nitrogen (N) and phosphorus (P) in the soil of leafy vegetable cultivation after 25 crops continuous application under greenhouse condition. There were six treatments, including: 1. Applying cattle dung compost (CDComp); 2. Applying hog dung compost (HDComp); 3. Applying poultry dung compost (PDComp); 4. Applying soybean meal (SBM); 5. Applying pea residue and rice hull compost (PSRComp) and 6. Applying the five organic fertilizers mentioned above in turn (RotAPP). All treatments were repeated four times and arranged in randomized complete block design. After 25 crops of leafy vegetable being cultivated, the soils were sampled for analysis. The methods proposed by Bremner and Sui and Thompson were used to fractionate N and P, respectively, into different fractions. The results indicated that different organic fertilizers had different effects on soil chemical properties, N fractions, and P fractions. Treatments of CDComp, SBM, and PSRComp resulted in accumulation of inorganic N, available P and potassium to very high concentration. Continuous application of SBM results in the soil decrease in pH value, organic carbon content and total nitrogen content. The disadvantage of continuous application of one kind of organic fertilizer could be avoided through application of different organic fertilizers in turn. Long-term application of different organic fertilizer not only change the concentrations of different fractions, but the proportion of different fractions of N and P in soil, respectively. In summary, soil testing before fertilization is very important or will result in degradation of the soil. |
