摘    要:采用盆栽试验,研究了不同氮源条件下,钼酸铵浸种对油菜产量、品质及氮磷钾(NPK)吸收的影响。结果表明:NH4NO3+Mo对提高鲜食油菜的鲜重和干重具有显著作用;NH4Cl+Mo对油菜Vc含量和叶绿素含量具有显著的提高作用,NH4NO3和(NH4)2SO4与钼配施效果不及NH4Cl。同一时期内的油菜植株Vc含量与叶绿素含量呈正相关;在NPK的吸收方面,不同种类氮肥的阴、阳离子与钼互作效应不同,硝酸铵与钼配施时,钼与NPK均表现协同作用,而NH4Cl和(NH4)2SO4与钼配施时,钼与氮、磷表现协同作用,而钼与钾表现拮抗作用。

关 键 词:鲜食油菜  钼酸铵浸种  产量与品质  NPK吸收

Abstract:Basin cultivate experiment was carried out and the effect ofimmensing seed on the yield and quality of rape and the absorption of N P K at different N source was studied.The result shows: the effect of applying (NH_4)_2MoO_4 to match Mo on increasing fresh weight and dry weight of rape is remarkable, and the effect of applying NH_4NO_3 to match (NH_4)_2SO_4 was worse than NH_4Cl.The relation between rape Vc content and chlorophyll content is positive. On the absorption of N P K side, the reciprocal function of positive and negative ions of different N types and Mo is different .When applying NH_4NO_3 to match Mo, Mo works in coordination with N P K but when applying NH_4Cl(NH_4)_2SO_4 to match Mo, Mo works in coordination with N P but resist with K.
Keywords:ofimmensing seed  pak-chor  yield and quality  absorption of N P K
