摘要
为合理确定人工栽培何首乌的最佳采收期，采用多指标综合评价分析方法，对1～3年生不同采收期何首乌样品进行了综合评价。结果表明：二苯乙烯苷含量以2年生11月中旬至12月上旬达最大，且相对稳定；蒽醌类成分含量高峰期在12月中旬；产量在12月中上旬最高。综合考虑产量、有效成分含量变化、经济效益、劳动成本、时间成本和实际生产因素等，何首乌以大田种植2年，12月中下旬采收为宜，可达产量高、质量优和效益最大化的目标。
The P. multiflorum samples with 1 -3 years old collected in different harvesting periods was evaluated by the multi-index comprehensive scoring method to determine the optimum harvesting period rationally. The results showed that the stibene glucoside content of P. multiflorum with two years old harvested from the middle ten-day period of November to the first ten-day period of December reached the maximum, the anthraquinones content of P. rnultiflorurn was up to the peak in the middle ten-day period of December and the highest P. multiflorurn yield was in the first ten-day period and the middle ten-day period of December. The rational harvesting period of P. rnultiflorurn with two-year old should be in the middle ten-day period and the last ten-day period of December to realize the goal of high yield, good quality and best economic benefit.
