为探明适合重庆地区春播种植甜荞的栽培技术，以信农1号为材料，采用3种播期（主区）、3种播种量（裂区）和3种施肥量（再裂区）的3因素裂-裂区试验，研究不同播期、播种量和施肥量对甜荞产量及主要农艺性状的影响。结果表明，播期对产量和千粒重有极显著影响，对株高有显著影响，对主茎节数、分枝数、单株粒数、单株粒重无显著影响；播种量对产量有显著影响，对主要农艺性状的影响不显著；施肥量对产量、株高、主茎节数、分枝数、单株粒数、单株粒重有极显著影响，对千粒重影响不显著。对产量与主要农艺性状的相关性分析表明，产量与株高、分枝数、单株粒数、单株粒重呈极显著正相关，与主茎节数呈显著正相关，而与千粒重呈不显著的正相关。在重庆地区春播种植甜荞时，以播期为3月5日，播种量为67．5 kg/hm2，施肥量为225 kg/hm2较好。

To explore the cultivation techniques suitable for planting F.esculentum in Chongqing in Spring,F.esculentum Xinnong 1 was grown in a experiment of three-factor crack-split plot design with three sowing dates (main plots),three seeding rates (split plots)and three fertilizations (again split plots) to study the influence of sowing date,seeding rate and fertilization on yield and main agronomic traits of F.esculentum.The result showed that the yield and 1000-grain weight were extremely significantly influenced by sowing date.Sowing date had a significant effect on plant height and no significant effect on primary stalk pitch number,branch number,grain number per plant and grain weight per plant.Seeding rate had a significant effect on yield and no significant effect on main agronomic traits.Fertilization had extremely significant effects on yield,plant height,primary stalk pitch number,branch number,grain number per plant and grain weight per plant and no significant effect on 1000-grain weight.The results of correlation analysis between yield and main agronomic traits indicated that the yield had a extremely significant positive correlation with plant height,branch number,grain number per plant and grain weight per plant,and a significant positive correlation with primary stalk pitch number,but no significant positive correlation with 1000-grain weight.In conclusion,the combination of sowing date of March 5,seeding rate of 67.5 kg/hm2 and fertilization of 225 kg/hm2 is recommended for F.esculentum cultivation with spring planting in Chongqing.
