白城地区播期和播量对藜麦农艺性状和产量的影响

Effects of Sowing Date and Sowing Rate on Agronomic Characters and Yield of Quinoa in Baicheng Area

[目的]选出白城地区藜麦的最佳播种期和播种量。[方法]以白城市农业科学院系选品系编号2013-BL113藜麦为材料,在白城地区采用两因素裂区试验设计,以播期为主处理、播量为副处理,研究播期和播量对藜麦农艺性状和产量的影响。[结果]随着播期的延迟,生育期逐渐缩短;株高、无效分枝、单株重和小区产量受播期影响显著,有效分枝和第一次有效分枝部位受播种密度影响显著;在试验设计范围内,最佳播种时期为5月6日,最适宜种植密度为56700株/hm 2,产量最高达到2359.60 kg/hm 2。[结论]该研究对白城地区藜麦种植提供了理论依据。

[Objective]The best sowing period and sowing rate of quinoa in Baicheng area were selected.[Method]The effect of sowing date and sowing rate on the agronomic characters and yield of quinoa was studied by using 2013-BL113,a selected strain of Baicheng Academy of Agricultural Sciences,as the material,and using two factor split plot experiment design in Baicheng area,with the main treatment of the sowing date and the secondary treatment of the sowing rate.[Result]With the delay of sowing time,the growth period gradually shortened;plant height,ineffective branches,plant weight and plot yield were significantly affected by sowing date,the effective branches and the first effective branch were significantly affected by sowing rate;within the experimental design range,the best sowing date was May 6,the optimum sowing rate was 56700 plants/hm 2,and the maximum yield could reach 2359.60 kg/hm 2.[Conclusion]This study provides a theoretical basis for quinoa planting in Baicheng area.
