叶面喷肥对强筋小麦产量和品质的影响

Effect of Different Foliar Fertilizers on Grain Yield and Quality of Strong Gluten Wheat

研究了在中、高肥力壤质潮土上叶面喷施不同品种肥料对强筋小麦产量和品质的影响，结果表明：基础产量为4500～6500kg／hm^2的试验点上喷施0．3％磷酸二氢钾、0．2％硫酸锌、0．05％钼酸铵均有较好的增产效果；喷施2％尿素或0．3％磷酸二氢钾可提高小麦籽粒粗蛋白含量。基础产量迭7000kg／hm^2的试验点喷肥对小麦产量及粗蛋白含量无显著影响。

The studies on yield and protein of strong gluten wheat sprayed with different foliar fertilizers and grown in aquatic soil were conducted and the result was as follow： in the wheat yield of 4 500 - 6 500 kg/hm^2, the yield was increased when 0.3 % KH2PO4,0.2 % ZnSO4 or 0.05 % （ NH4 ）6Mo7 O-24 was sprayed in wheat leaf and the protein content was increased when 2% urea or 0.3% KH2P04 was sprayed. In the wheat yield of 7000 kg/hm^2,there was no obvious effect of the fertilizer sprayed on yield and protein content.
