| 摘 要： | 根据施肥和密度2个因素3个水平9个处理,研究了小花盾叶薯蓣的块茎形成规律.结果表明,1年生和2年生的小花盾叶薯蓣次生根茎的生长规律基本一致,都是典型的单峰曲线,但峰值时间不一致.不同肥料配比之间差异不显著,不同密度水平之间差异极显著;连续生长2年的次生根茎的产量是1年生的1.70～3.87倍.影响产量的因素主要有密度、生长年限以及栽培模式等.

| Abstract: | The field test by 9 treatments with 3 levels of 2 factors of fertilization and density in 21303 - 2004 showed the growth law of secondary rhizome was basically consistent for 1-year-old and 2-year-old D. parviflora. They were typical single peak curve with peak value time unconsistent. The difference between different fertilizer combinations was not significant and that between different density level was specially significant. The yield of secondary rhizome growing continuingly for two years was 1.70-3.87 times of that of 1-year-old secondary rhizome. The main factors effecting yield were density, growth duration and cultivation model etc. |
