活体植物搭架对药用党参产量的影响

Effects of Plant Scaffolding Cultivation on the Yields of Medicinal Codonopsis pilosula

为了研究活体植物搭架对药用党参产量和经济效益的影响及对根系病害的降低效应,采用随机区组设计,以常规不搭架和人工竹子搭架为对照,设蚕豆、油葵、谷子3种活体植物搭架方式,研究了活体植物搭架对党参生长和产量的影响。结果表明,活体植物搭架的党参产量均高于人工竹子搭架和常规不搭架,且收获的相应活体植物蚕豆、油葵和谷子增收均在1000元/hm^(2)以上。党参产量以蚕豆搭架最高,其次是油葵搭架,谷子搭架排第3,分别为6119.2、5985.8、5865.5 kg/hm^(2);产值分别为48953.6、47886.4、46924.0元/hm^(2)。综合性状表明,蚕豆搭架的党参地上部和根系农艺性状较好,增产作用大,经济纯收益高,特级和一级品党参的生产率高,根腐病发病率和病情指数低。因此,蚕豆搭架栽培有利于提高党参的产量,适宜在高寒二阴区推广应用。

In order to study the effects of plant scaffolding cultivation technique on yields,economic return and reduction of root diseases of medicinal Codonopsis pilosula,a randomized block design was used to design the scaffolding technology treatments with broad bean,oil sunflower and millet.The conventional non-scaffolding(CK1)and artificial bamboo scaffolding technology(CK2)were used as controls,and the effects of plant scaffolding on the growth and yield of Codonopsis pilosula were studied.Results showed that yields in plant scaffolding were all higher than these of the two controls and the harvest of scaffolding crop could all generate an extra income of over 1000 Yuan/ha on average.Yield in broad bean scaffolding was the highest,followed by oil sunflower scaffolding and millet scaffolding,which were 6119.2,5985.8 and 5865.5 kg/ha,respectively,and the economic return was 48953.6,47886.4 and 46924.0 Yuan/ha,respectively.To sum up,the above ground and root agronomic characters of Codonopsis pilosula planted on broad bean were ideal,which showed large yield increase,high economic net income,high productivity of super grade and first grade Codonopsis pilosula,and low incidence rate and disease index of root rot.Therefore,the cultivation of broad bean scaffolding is beneficial for increasing the yield of Codonopsi spilosula,and is suitable for promotion and application in alpine humid regions.
