壤质土叶面喷施不同养分对强筋小麦产量和蛋白质组分的影响

Effect of Leaves Spraying of Different Nutrients on the Yield and Protein Component of Strong Glutinous Wheat Growing on Loam Soil

在壤质土条件下,不同养分叶面喷施对强筋小麦的株高、成穗数影响不显著;叶面喷洒0.1%MnSO4、0.05%(NH 4)2M oO2和0.3%KH 2PO4、2%CO(NH 2)2等能提高强筋小麦的千粒重和产量。喷洒2%CO(NH 2)2和0.1%M nSO4有利于蛋白质和蛋白组分的提高。

Results of field trials during 2003-2005 showed that the effect of leaves spraying of different nutrients on the stem height and ear number per hectare of strong glutinous wheat growing on loam soil was not significantly. Leaves spraying of 0.1% MnSO4, 0.05% （NH4）2MoO2, 0.3%KH2PO4 and 2% CO（NH2）2 at 750 kg per hectare increased the yield and 1 000-grain weight, and leaves spraying of 2% CO （NH2）2 and 0.1% MnSO4 at 750 kg per hectare increased the content of crude protein and protein component.
