| 摘 要： | 通过砂培试验,研究了不同供钾水平对四种水稻幼苗生长特性的影响,结果表明:缺钾条件水稻幼苗生长受到明显的抑制,表现为生长缓慢,生物量减少,根系生长受抑制;低钾条件对辽粳294影响较小,对高优35影响较大;高钾条件影响植株生长,使根冠比下降,鲜重增长缓慢;相关分析表明,全钾含量与株高成正相关.

| Abstract: | Influences of growing and nutrient characters of four kinds rice seedling are studied at different potassium levels by sand culture.The results shows: growth of seedlings are restrained obviously from potassium deficiency,and seedlings grows slowly,biomass decreases,at the same time,growth of root are checked.Influence of low potassium on Liaojing 294 is very small,and on Gaoyou 35 obviously.High potassium level decrease root /shoot ratio.Fresh weight increases slowly.Correlation analysis indicates there is a positive relationship between potassium content and plant height. |
