南方芦笋留母茎栽培的施肥技术研究

Research on the Apply Fertilizer Technique of Reserved Maternal Plant Culture of Asparagus in South China

摘要: 在南方高温多雨的气候条件下,润沙土的芦笋园,留母茎栽培,较为经济合理的N、P、K亩用量为N 52kg、P2O5 13kg、K2O 47kg即N:P2O5:K2O比例为1:0.25:0.9。施肥量以采笋前、采笋期中和采笋截止后,分别占总肥量的30%、40%和30%为最佳,可发挥N、P、K肥对芦笋产量的最大效应,收到最好的经济效益。

Abstract: The reserved maternal plant culture of asparagus was applied by N P K.Its econo-reasonable rates were N 52kg,P2O5 13 kg and K2O 47 kg.N : P2O5 : K2O is 1 : 0.25: 0.9 in raing and high temperate climate in wet sand soil in asparagus garden plot.30% total application was applied before and stop of picking asparagus respectively.40% of total topdressing is best in picking period.This fertilizer of N P K gives biggest effectivity on asparagus yield.It can gain best economic effect.
