摘要
为筛选适宜的施肥配方,促进茎瘤芥产业的绿色发展,本试验根据茎瘤芥需肥量和需肥规律以及对氮、磷、钾的吸收比例设计施肥方案,开展4个施肥配方的比较试验。通过对植株生长、瘤茎品质、产量效益和化肥减量等指标的综合分析,基肥N∶P∶K=15∶15∶15、追肥N∶P∶K=25∶10∶16和基肥N∶P∶K=15∶15∶15、追肥N∶P∶K=21∶6∶13两个施肥配方的瘤状茎商品性好、产量效益较好、化肥减量幅度大,适宜在生产中示范应用。
In order to screen out the suitable fertilization formula,promote green development of tuber mustard industry,the comparison experiment of four fertilization formulations about the fertilization scheme was designed according to the amount and rule of fertilizer requirement and the absorption ratio of N,P,K in tuber mustard.Through the comprehensive analysis of plant growth,stem quality,yield and benefit and fertilizer reduction,the two fertilizer formulations had good effects,including basal manure N∶P∶K=15∶15∶15,top application N∶P∶K=25∶10∶16,and basal manure N∶P∶K=15∶15,top application N∶P∶K=21∶6∶13.The two fertilizer formulas had good marketability,good yield,good benefit and large fertilizer reduction,which were suitable for demonstration application in production.
