不同施肥措施对竹节参根茎产量的影响

Study on Effects of the Yield of Panax japonicus Adopting Different Spreading Measure

采用田间试验的方法,研究了不同施肥措施对我省地道药材竹节参根茎产量的影响,同时分析了在不同施肥措施下竹节参的经济效益。结果表明:氮磷钾肥与有机肥配合施用是获得最好增产效果和最佳经济效益的施肥措施。亩施腐熟有机肥2 500 kg+尿素20 kg+普通过磷酸钙25 kg+硫酸钾15 kg是最优的处理。比对照根茎鲜重增产52.7 kg/亩,增产66.5%,增加产值2 698.4元/亩。

Objective To study on the yield of Pana.r japonicus adopting ditterent spreading measure, and also analyze economic benefit of increasing yield of Panax japonicus Methods To adopt methods of farm experiment. Results Comparison with reference groups, the experiment groups may increase wet weight of Rhizoma Panax japonicus ,when every mu supplying organic fertilizer of compost 2 500 kg and adding urea 20 kg and adding calcium super phosphate 25 kg and adding potassium sulphate 15 kg, increased yield is over to 52.7 kg,increased per cent is over to 66.5% and output value is to 2 698.4 yuan RMB. Conclusion It is showed that spread measure is one of the best for N,P,K fertilizers and organic compost cooperate spread and may well increase yield and economic benefit of Rhizoma Panax japonicus
