施氮量对幼龄胡椒根系生长及抽穗的影响
Nitrogen Rate on Root Growth and Heading of Pepper
摘要
Abstract
In order to evaluate the nitrogen (N) rate on root growth and heading of pepper,the experiment was conducted with five N treatments in pots.The five N treatments named N1,N2,N3,N4 and N5 were 0,1,2,3 and 4 g N per pot,respectively.The results showed that appropriate N rate increased SPA D reading,dry matter,root growth,and flower of pepper.Length,surface area,length per volume,and volume of pepper mot increased in appropriate N rate.Appropriate N rate promoted early flowering and more flower spike of popper.However,excessive N rate reduced SPAD reading,dry matter,mot growth,and flower of pepper.Length,surface area,length per volume,and volume of pepper root decreased in excessive N rate.And excessive N rate delayed flowering and reduced the flower spike.Therefore,the appropriate N rate is 1 to 2 g per pot of pepper in this container experiment.关键词
