皖南烟区烤烟干物质和养分的积累研究

Research on Dry Matter and Nutrient Accumulation in Flue-cured Tobacco in Growing Area of South Anhui

摘要

摘要: 对皖南烟区烤烟干物质和养分积累规律进行了研究,结果表明烟苗移栽后30d内烟株干物质积累较少,仅占总积累量的3%;移栽后31~75d,烟株干物质积累量达到总积累量的69%;移栽后75d至采收,干物质积累量占总积累量的28%。在烟株生长发育早期,干物质在叶后中分布比例较高,栽后75d趋于相对稳定,根、茎、叶的干物质重分别约占全株干重的14%、32%和54%。烟株移栽后30d至75d时氮、磷、钾、氯、镁、锰、锌、铜的积累量分别占总积累量的69.18%、56.66%、79.82%、58.54%、73.75%、48.03%、53.28%、71.06%。

Abstract: The dry matter and nutrient accumulation in flue-cured tobacco in tobacco growing area of south Anhui was studied.The results showed that less dry matter was accumulated during 30 days after transplanting, which only accounted for 3 percent of the total accumulation, the amount of dry matter accumulation during 31-75 days after transplanting was 69 percent of the total.From then until harvest, the amount of dry matter accumulation was 28 percent of the total.The distribution ratio of dry matter was high in leaf during early growing stage, and became relatively stable in 75 days after transplanting.The amount of dry matter in root, stalk and leaf was 14%, 32%, 54% of the total accumulation, respectively.During 31-75 days after transplanting, the amounts of N, P, K, Cl, Mg, Mn, Zn, and Cu were 69.18%, 56.66%, 79.82%, 58.54%, 73.75%, 48.03%, 53.28%, and 71.06% of the total, respectively.
