摘要
目的：对铁皮石斛的最佳采收期进行理论探索，以期更好地指导生产实践。方法：通过成分分析与数学计算相结合的方法对铁皮石斛不同生长期的产量、有效成分含量及功效进行综合评价，并求算出各种评价指标及综合采收指数。结果：１～４年茎的采收指数依次清音明目为５６９，９５４，１７９，２２２；增强免疫１１２，１４６，２１６，１７６；综合采收指数依次为８４，１２１，１９７，１９９。结论：以清音明目为治疗目的时，应在第４年采收；以增强免疫为治疗目的时，宜在第１或第３年采收；若兼顾上述两者及产量。
Objective:To explore the theory on the best time for harvesting Dendrobium candidum so that the production of the herb can be directed more effectively.Method:Based on a component analysis in combination with mathematical calculation, a synthetical appraisal on the yield,contents of effective components and efficacy of D.candidum in different growing periods has been made ,and different appraisal indexes and synthetical harvesting indexes have been worked out. Result:The harvesting indexes from the first year to the fourth year are as follows:569,954,179,222(curing throat and eye diseases); 112,146,216,176(strengthening immunity);844,121,197,199(the abovementioned indexes and yield factor considered together). Conclusion:The best time for harvesting D.candidum is in the fourth year for curing throat and eye diseases;in the third or first year for strengthening immunity;and in autumn of the third year if the abovementioned indexes and yield factor are to be considered together.
