摘要
通过在温室内对兰考泡桐实生幼苗营养的试验.结果表明,稳态营养能按指数增长地供应营养物;幼苗每天相对生长速率、生物量增加及其分配、营养物利用率等均明显地优于传统营养.揭示出稳态营养为生理学及生态生理学深入研究提供了必要条件和手段,为施肥研究开辟了新途径.
The results of greenhouse pot experiments with Paulovunia elongata seedlings indicate that the daily relative growth rate,biomass increment and partition of seedlings as well as nutrient use efficiency in the treatment of steady state mineral nutrition (in which the nutrients can be supplied exponentially according to the growth of seedlings) are much better than treatments in traditional culture.It reveals that the steady state mineral nutrition provides a necessary condition and means for further study of plant physiology and ecophysiology,and opens a new path for fertilization research
