摘要
研究不同密度对江西车前产量及其构成因素的影响以及产量与产量构成因素的相关性。结果表明,在8.0～13.6422万株/hm2范围内,车前产量随着密度的增大而增加;超过13.6422万株/hm2,则产量呈下降趋势。通过二次曲线拟合得出车前高产栽培最适密度为13.6422万株/hm2。
The effects of the different densities on the yield and yield components of Plantago asiatical L. were studied. The result indicated that the yield increased with the density when the density was in the range of 8.0～13.642 2 million plants/ hm^2,and it had a descend tendency when the density was more than (13.642 2) million plants/ hm^2. According to the result of simulation by the quadratic curve model, the density of (13.642 2) million plants/ hm^2 of Plantago asiatical L. was the best for high yield.
