摘要:目的:研究党参的生长变化动态及其在不同栽培条件下的干物质消长规律,确定科学合理的田间管理。方法:采用2因素4水平随机区组法进行试验。结果与结论:掌握了党参各生长发育阶段干物质的消长变化规律,不同生长发育时期开始和结束的时间及其生物学特性的变化过程;在栽植密度和施肥量2因素效应下,对茎叶重的增加最具优势的处理组合为密度105万株/hm2和施肥量240 kg.hm-2,对单根鲜重增加最具优势的处理组合为密度60万株/hm2和施肥量240 kg.hm-2。有利于党参的规范化生产、产量的提高和质量的稳定。
Objective: To study on the dynamic changes of Codnopsis pilosula for the guidance of the field management. Method: Using the random method the influences of the ctdtivating density and fertilizing weight at four different levels was observed. Result and Conclusion: The dynamic changes of the biomass, growth period and biological changes at different growth stages were found out. The most predominant combination of the two factors, the 1.05 million roots/hm^2 of the cultivating density and 240 kg· hm^-2 of the fertilizing weight reached the highest accumulation of sterns & leaves; 652 mg·d^-1 the 0.6 million roots/hm^2 and 240 kg·hm^-2 reached the heaviest single fresh mot. The results could be used for the cultivating, fertilizing and practicing SOP of C. pilostda.
