摘要
本文是在酸性土上对新银合欢种苗期内通过不同措施处理,以探索它的生态特性与培育技术的相关性。研究结果表明,施过磷酸钙而不施石灰或不供尿素也能获得较高的苗期生物量;一定量的石灰对生物量有显著促进作用;在施磷肥时,少量尿素对幼苗生长有明显效果,但它显著抑制种子发芽。
For working out the relation between the ecological property and cultivation technique of Leucaena leucocephala cv Salvador, the growth and behaviour of several seedlings were studied with different treatments in acid soils. The studies reported in this paper on the seedlings showed that with calcium superphospate applicaion relatively high biomass could be gained even though no lime or urea was provided. Moderate liming improved growth markedly. A little urea promoted growth when accompanied by P application. Urea repressed germination.
