摘要
为探究不同播种量对新春37号小麦农艺性状及产量的影响,设置5个播种量处理(26~34 kg/667 m^(2)),测定农艺性状、产量及效益指标。结果表明,播种量对小麦农艺性状影响显著(P<0.05),其中32 kg/667 m^(2)处理(D)的株高、单位面积穗数、分蘖成穗率、穗粒数及千粒质量均最优;小麦产量随播种量增加呈先增后减的趋势,D处理的产量最高(636.5 kg/667 m^(2)),单位面积产值与效益也最大。综上,32 kg/667 m^(2)为新春37号小麦的最佳播种量。作—秸秆还田及智能水肥一体化等玉米旱作节水种植技术的集成应用模式,并通过试点示范量化了其经济、社会与生态效益。
To explore the effects of different sowing rates on the agronomic traits and yield of Xinchun No.37 wheat,five sowing rate treatments were set up to determine the agronomic traits,yield and benefit indicators.The results showed that the sowing rate had a significant effect on the agronomic traits of wheat.Among them,the treatment of 32 kg/667 m2(D)had the best plant height,number of panicles per unit area,tillering spike formation rate,number of grains per spike and quality per thousand grains.The wheat yield showed a trend of first increasing and then decreasing with the increase of sowing amount.The yield of treatment D was the highest,and the output value and benefit per unit area were also the greatest.In conclusion,32 kg/667 m2 was the optimal sowing rate for Xinchun No.37 wheat.
