不同播种量对小麦农艺性状及产量的影响

Effects of Different Sowing Rates on Agronomic Characters and Yield of Wheat

为研究不同播种量对小麦农艺性状及产量的影响,设置4个播种量,研究小麦干物质积累量和产量性状的差异特征。结果表明,播种量显著影响小麦干物质积累量,在播种量为16 kg/667 m^(2)时小麦干物质积累量最高,产量在16 kg/667 m^(2)处理时达到最大值,达到541.44 kg/667 m^(2),经济效益最好,因此,在宿州市埇桥区蕲县镇淮麦44的最佳播种量为16 kg/667 m^(2)。

In order to study the effects of different sowing rates on wheat agronomic traits and yield,four sowing rates were set up to study the difference characteristics of wheat dry matter accumulation and yield traits.The results showed that seeding amount significantly affected wheat dry matter accumulation.When seeding amount was 16 kg/667 m^(2),wheat dry matter accumulation reached the highest value,and the yield reached the highest value at 16 kg/667 m^(2),reaching 541.44 kg/667 m^(2),which was the best economic benefit.The best sowing amount of Huaimai 44 in the Yongqiao district of Suzhou City was 16 kg/667 m^(2).
