於藺草臺農選1號之生育中、後期,配合氮肥施用鉀肥,每公頃施用鉀素(K2O)量為75、150、225及300 kg/ha四種變級,分別以氯化鉀施用(A)125、(B)250、(C)375與(D)500 kg/ha,及以硫酸鉀施用(E)150、(F)300、(G)450與(H)600 kg/ha,計八種處理,並以不施鉀肥區(Ⅰ)為對照,探討對藺草品質與產量之影響。結果發現一、二級草總和莖數率(100 cm以上)以施用250 kg/ha氯化鉀處理最高,對藺草品質之提昇有最好的效果。每公頃乾草產量以施用氯化鉀375 kg/ha處理稍高,唯長草量較低。施用鉀肥確可提昇藺草品質,但對產量影響較小。肥效比較發現施用氯化鉀之肥效有比硫酸鉀優異之趨勢,顯示藺草品質似受氯根之影響較不明顯。鉀素利用率對藺草品質與產量並無直接影響,但鉀素吸收量與植體含鉀濃度均與長草率有顯著相關。
The effects of KCl and K2SO4 fertilizers applied at the middle and late growing stages on the grass quality and yield of mat rush cv. Tainung No. 1 was studied. Four levels of K2O, i.e., 75, 150, 225 and 300kg/ha, were applied for both KCl (designated as A, B, C and D treatments, respectively) and K2SO4 (E, F, G and H treatments, respectively) fertilizers. A check plot (treatment Ⅰ) without K fertilization was also included. Experimental results inicated that treatment B (150kg K2O/ha as KCl) produced more grass in the 1st and 2nd grades (with length over 120 and 100 cm, respectively) but less grass in the 3rd (with length between 75 and 99 cm) than other treatments. Treatment C (225kg K2O/ha as KCl) gave the highest grass yield, however, the effect of K fertilization on yield was not significant in general. Treatments B and D (300kg K2O/ha as KCl) were most effective in terms of the percentage of 1st grade grass produced. Based on the above results, potassium fertilization effected more on quality than on yield of mat rush grass. Comparison between the two types of K fertilizer revealed that KCl was superior to K2SO4 in mat rush production. The assumption that chloride ion did not affect grass quality was also proposed. The K utilization efficiency was not correlated to either the quality or yield of mat rush. However, K concentration in plant tissue and the amount of K uptaked were positively correlated to the percentage of grass of the 1st and 2nd grades.
