| 摘 要： | 以花溪辣椒为试材,试验设置了5个施氮水平每桶分别施纯氮0.0 g3、.0 g6、.0 g(CK)9、.0 g1、2.0 g],以正常施氮水平(每桶施氮6.0 g)为对照,研究了不同施氮量对花溪辣椒的株高、株幅、茎粗及落花的影响。结果表明:辣椒生长前期每桶施纯氮3.0 g水平下的辣椒株高、株幅和茎粗生长协调合理;自中期开始以每桶施纯氮6.0 g水平下(CK)辣椒的株高、株幅和茎粗营养生长和生殖生长协调合理,辣椒落花最轻,表现最好。施氮过多和过少都能导致辣椒株高、株幅和茎粗生长不协调,落花严重。

| Abstract: | Five nitrogen application amount 0.0 g,3.0 g,6.0 g(CK),9.0 g,and 12 g/hole] was applied to investigate effects on plant height,plant width,stem diameter and flower drop of Huaxi pepper variety.The results show that the growth under 3.0 g/hole of N application amount is normal at the growth prophase in plant height,plant width and stem diameter and the growth under 6.0 g/hole of N application amount is normal from the growth intermediate stage in plant height,plant width and stem diameter,reproductive development and slightly flower drop,which is the best growth performance in tested treatments. |
