摘要
为探讨黑龙江中部地区万寿菊合理栽培密度及群体活动,进行了种植密度与万寿菊植株生物学性状和总产量关系的研究,结果表明,不同密度下,寒地万寿菊株高、茎粗、株冠直径和干物质积累均存在差异,且总产量差异显著,最适宜的种植密度为4.05～4.5万株/hm2。
In order to discuss the rational sowing density of tagetese recta L. in the middle area of Heilongjiang province, the biological characters in different growth stages and total yield of tagetese recta L. in different planting density were analyzed. The results indicated that the plant heights, stem thick, crown diameter, dry matter accumulation existed obvious difference under different sowing density and the difference of total yield was ultra-significant. The appropriate planting density should be 4.05～4.50 ten thousand plants/hm^2.
