| 摘 要： | 1、生菜的N、P、K含量与生育期有一定的关系,不论氮肥施用情况如何,生菜生长的前后期体内N、K的含量均表现为逐渐下降的趋势,而P则没有明显的规律;2、施肥后较短的时间范围内,生菜体内N、P、K的含量均随着氮肥用量的增加而升高;而生菜生长的中后期,体内N、P、K的含量与氮肥用量之间则没有明显的相关性.

| Abstract: | (1) There are certain relations between grow period and contents of N,P,K in romaine lettuce, no matter what about fertilizer nitrogen uses, in the all grow periode , the contents of N,K in the body of romaine lettuce show a downward trend gradually , P does not have obvious regulation. (2) After applying fertilizer nutrition in a short time, the contents of N,P,K in the body of romaine lettuce raise with increase of fertilizer nitrogen; Later stage in the grow of romaine lettuce, there are no abvious dependence between internal N,P,K and quantity of applying fertilizer nitrogen. |
