氮磷钾不同施肥水平对橡胶草生长发育的影响
Effects of Different Fertilizer Treatments on Taraxacum kok-saghyz Growth and Development
摘要
Abstract
This study was conducted to determine the effects of different fertilizer applications (nitrogen and phosphate and kalium) on the agronomic traits of Taraxacum kok-saghyz (TKS) at different growth stage,and their correlation analysis was carried out.The results showed the growth indices of the main agronomic characters including leaf length,leaf width,leaf index and so on were affected at different degrees,and the indices were significantly higher than the control (p＜0.05).TKS plants were mainly influenced by N at growth period with rapid growth,and gradually influenced by P at squaring period,and remarkably influenced by P at flowering and seedsetting stage with slow growth.Scape length and scape number was significantly affected by P,and inflorescence size was affected by K and P at flowering and seed-setting stages.In addition,the leaf length had a significant positive correlation with leaf width,leaf index,plant width,scape length,scape number,inflorescence length and inflorescence width.Leaf width had a remarkable positive correlation with leaf index but a striking positive correlation with plant width,scape length,and scape number.Plant width had a remarkable positive correlation with scape length,scape number and inflorescence width.Scape length had a remarkable positive correlation with scape number and inflorescence width.关键词
