配方肥对党参产量及品质的影响

Effect of Special Fertilizer on Yield and Quality of Codonopsis pilosula

田间条件下党参配方肥对党参产量及经济效益的影响。结果表明,合理施用氮、磷、钾肥、生物炭及硫酸锌能够产生显著的增产、增收效果。党参产量为2323.38±155.76kg/hm^2,较农民习惯施肥增产33.89%,增加纯收益12845元/hm^2;党参炔苷含量、多糖含量分别较农民习惯增加0.02、1.34百分点。因此,党参推荐施肥过程中,在均衡氮磷钾养分的基础上,还需结合考虑土壤调理,才够能提高党参的产量和品质。

Effects of different fertilization on Codonopsis pilosula yield, quality and economic benefit were studied by using field experi- ment. The results showed that reasonable application of nitrogen, phosphorus, potassium fertilizer, biochar and ZnSO4 could signifi- cantly increase the production. The average yield was 2323.38 ± 155.76kg/hm2 , increased by 33.89% ; and the net income increased by 12845 yuan/hm2 ;also the lobetyolin content, the polysaccharide content, increased by 2% and 1.34%, respectively. Therefore, considering the fertilization using on Codonpsis pilosula , it was necessary considering not only nitrogen, phosphate and otassium fertil- izer balance but also the nutritive characteristics of different conditioner. A reasonable usage of fertilizers may increase both the yield and quality of Codonpsis pilosula.
