Abstract
The experiment was carried out in the Agricultural Research Farm of the National Taiwan University during the winter of 1997. There were four kinds of treatments in total including a conventional chemical fertilizer control and three rates (30, 60 and 120 Mg ha-1) of compost-treated plots. The cabbage (Brassica oleracea L. Capitata Group, cultivar early spring) was harvested after 94 days of transplanting. After being washed, the plants were divided into the root, the wrapper leaf petioles, the wrapper leaf blades, and the head (the marketable portion). The dry weight and the concentrations of the total nitrogen (N), phosphorus (P), potassium (K), nitrate N (N03-N), ammonium N (NH-N) and insoluble N in various parts of the plants were determined. The results showed that there were no significant differences in the growth of various treatments, However, the productivity of the head of 120 Mg ha-1 compost- and chemical fertilizer-treated plots were higher than those of the 30 Mg ha-1 and 60 Mg ha-1 compost-treated plots. The total N and K concentrations of various parts of the plants were not significantly different for the treatments. However, the P concentrations in the chemical fertilizer-treated plants were lower and those in compost-treated plants increased with increasing the compost rate. The NO-N concentrations in the whole plant, the wrapper leaf blades, and the head of the chemical fertilizer-treated plants were the lowest among all treatments and there were no significant differences in the NO-N concentrations of the head among the compost treated-plots. There were no significant differences in the concentrations of NH4-N, soluble organic N, and insoluble N in various parts of the plants among the treatments. In conclusion, even though with the application of 120 Mg ha-1 of compost, there was no disadvantageous effect on the growth of cabbage, on the other hand, a good yield was obtained.
本研究之目的在探討不同量之豬糞堆肥對甘藍生長、氮、磷與鉀吸收及氮素組成分之影響，試驗在國立台灣大學農業試驗場進行。堆肥處理為每公頃30、60與120公噸三種，以施用化學肥料之處理為對照。甘藍於移植後94天採收，以水洗淨後，分成根、外葉葉片、外葉葉柄及球四部分，經烘乾後分析氮、磷、鉀、硝酸態氮、銨態氮與不溶解性氮濃度•結果顯示各種不同處理之不同部位之氮與鉀濃度無顯著差異，但是化學肥料處理之磷濃度顯著低於堆肥處理者，堆肥處理之磷濃度則隨堆肥施用量增加而增加；化學肥料處理之整株植物、外葉葉片及球之硝酸態氮濃度為各處理中之最低者，而堆肥處理間球之硝酸態氮濃度則無顯著差異；各處理不同部位之銨態氮、溶解性有機態氮及不溶性氮無顯著差異。整體而言，豬糞堆肥之用量高達每公頃120公噸，在第一年之結果裡對甘藍之生長顯出無不良之影響。
