[目的]探明适合江西省长治地区春播种植谷子新品种“长农39号”的栽培技术。[方法]采用3个播期(主区)、3个密度(裂区)和3个施肥量(再裂区)的3因素裂—裂区试验,研究不同播期、密度和施肥量对谷子产量及主要农艺性状的影响。[结果]播期对产量、单穗粒重、穗重和千粒重有显著影响,对株高、茎粗、穗长、穗粗无显著影响;密度对产量、株高有显著影响,对茎粗、穗长、穗粗、单穗粒重、穗重和千粒重影响不显著;施肥量对产量、茎粗、穗长有显著影响,对株高、穗粗、单穗粒重、穗重和千粒重无显著影响。对产量与主要农艺性状的相关性分析表明,产量与单穗粒重、穗重、千粒重、茎粗、穗长呈不显著的正相关关系,与株高、穗粗呈负相关关系。[结论]在长治地区春播种植“长农39号”谷子时,以播期为5月15日,密度为45.0万株/hm2,施肥量为农家肥3万kg/hm2+硝酸磷300kg/hm2较好。
[Objective] The research aimed to find out the cultivation techniques suitable for the spring sowing of the new millet variety Changnong 39 in Changzhi of Jiangxi Province. [Method] The 3-factor fissure-split zone experiment of 3 sowing dates (main area), 3 densities (split areas) and 3 fertilization areas Yield and major agronomic traits. [Result] Sowing date had a significant effect on grain yield, grain weight per panicle, panicle weight and grain weight per plant, but had no significant effect on plant height, stem diameter, ear length and ear diameter. Seed density had a significant effect on yield and plant height, , Spike length, spike diameter, grain weight per spike, spike weight and 1000-grain weight had no significant effect. The amount of fertilizer had a significant effect on the yield, stem diameter and spike length. The plant height, ear diameter, No significant effect. Correlation analysis between yield and main agronomic traits showed that there was no significant positive correlation between grain yield and grain weight per panicle, panicle weight, 1000-grain weight, stem diameter and panicle length, but negatively correlated with plant height and ear diameter. [Conclusion] When sowing “Changnong 39” millet in spring in Changzhi area, the planting date was May 15, the density was 450,000 plants / hm2, the amount of fertilizer was 30000 kg / hm2 of farmhouse fertilizer and 300kg / hm2 better.
