摘要
通过蒜青施肥试验,研究了硼钼镁不同施肥水平对蒜青产量和养分吸收的影响。结果表明:合理施用硼钼镁能够提高蒜青的产量和经济效益;当B、Mg、Mo施用量分别为0.03、0.016、0.3kg/667m2时,效益最好,增幅分别为:8.68%、10.12%、1.83%;施硼促进蒜青可食部分及全株对N、K和B的吸收;施钼提高可食部分及全株对N的吸收,降低对P、K的吸收,同时降低了不可食部分对于N、P、K的吸收;施镁可以提高可食部分及全株对N和Mg的吸收,降低对P的吸收,施镁降低蒜青不可食部分对N、P、K的吸收,少量施镁促进蒜青对K的吸收,大量施用抑制蒜青对K的吸收。
Effects of B,Mo and Mg on yield and nutrient uptake of garlic plants was studied through experiment of different fertilizer levels.The results showed that fertilize B,Mo and Mg properly can increase yields and economic profit of flowering chinese cabbage.The best economic profict was got when the amount of B,Mo,Mg were 0.03,0.016,0.3 kg/667m2,meanwhile,the increase amount were reached 14.27%,13.1%,14.51%.Fertilizing B could add absorption of N,K,B in esculent parts and total of garlic plants.Fertilizing Mo could promote the absorption of N and reduce the absorption of P,K in esculent parts of garlic plants;In inesculent parts,fertilizing Mo could reduce the absorption of N,P,K.Small amounts of Mo restrained Mo absorption,but increasing Mo concentration could improve Mo absorption in garlic plants.Fertilizing Mg could promote the absorption of N,Mg in esculent parts of garlic plants,at the same time,reduce the absorption of P in inesculent parts.Richness Mg could depress the absorption of K,however,large amounts of it restrained K absorption.
