摘要
[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.
Abstract
[Objective] The aim was to explore appropriate cultivation technology of Changnong 39 in Changzhi Region,Jiangxi Province.[Method] Using three factors of crack-split plot experiment including three sowing periods (main area),three densities(crack area)and three fertilization amount(crack area),effects on millet yield and main agronomic traits were studied.[Result] Sowing period had significant effects on yield,grain weight per spike,spike weight,1 000-grain weight,and had no significant effects on plant height,stem diameter,spike length,spike width;density had significant effecrs on yield,plant height,and had no significant effects on stem diameter,spike length,spile width,grain weight per spike,spike weight and 1 000-grain weight;fertilization amount had significant effects on yield,stem diameter,spike length,and had no significant effects on plant height,spike width,grain weight per spike,spike weight,1 000-grain weight.Yield was positively correlated with grain weight per spike,soike weight,1 000-grain weight,stem diameter,spike length,and was negatively correlated with plant height,spike width.[Conclusion] The conditions of sowing date May 15,density 45.0 × 104 plants/hm2,fertilization farmyard manure 3 × 104 kg/hm2 + nitric acid phosphate 300 kg/hm2 are good for Changnong 39 cultivating in Changzhi Region.
