主要作物施肥適量試驗(四)苧麻施肥適量試驗

Abstract

為深討苧麻三耍素施用適量，於民國43年開始在臺北、臺南兩地辦理試驗，其設計包括各要素施用不同量之處理共17，重覆4次，經統計分析結果氮施用量之增加達到顯著平準，由本試驗之成績可以推測苧麻之三要素施用量為每公頃氮90，磷30，鉀75公斤/公頃。 This experiment was conducted from 1954-4958 in Taipei and. Tainan in order to get information about the N-P-K requirement for ramie. It has 16 fertilizer treatments with four replication. Accerding to statisical analysis, the effect of nitrogen was very significent, the ramie yield in the plot at medium level of N-P-K varied from 300 to 1,000 kg/ha, from which we suppose that some other facters might have effected the crop yield. Certain difficulties here encountered in this experiment. From this ex periment we propose for the optimum N-P-K ratio the following 90-30-75 kg/ha.
