在牧草轮作制中插入豆科作物所显示出的优越性,使有关它们的营养需求的资料显得非常重要,在热带和亚热带地区的酸性条件下,尤其是这样。为此,利用盆栽试验,研究了9种豆科牧草在施用不同量石灰的酸性灰棕色砂壤土上的生长情况。一切必要元素都按正常水平施入,利用14公斤容量的米氏营养钵在温室内的受控条件下进行试验。每钵定苗12株。模拟田间持水量施入去离子水。淋出液与随 The superiority shown by the introduction of leguminous crops in pasture rotation makes information relevant to their nutritional needs important, especially under tropical conditions and in subtropical regions. Therefore, the pot experiment was conducted to study the growth of 9 leguminous species on acidic beige sandy loam soil with different amounts of lime. All necessary elements were applied at their normal level and were tested under controlled conditions in a greenhouse using a 14 kg Miellit bowl. 12 plants per pot Dingmiao. To simulate field water holding capacity of deionized water. With leaching fluid and with
