研究甜菜分期播种环境因子对甜菜糖锤度及产量的影响,为黑龙江省的甜菜合理栽培提供科学依据。对甜菜品种KWS3418在5个不同播期条件下的环境因子、产量和糖锤度进行测定,分析它们之间的相关性。结果表明,播期对土壤含水量影响较小;气温积温与产量、糖锤度显著正相关;在黑龙江省甜菜品种KWS3418适宜早播;各环境因子与产量的相关性为气温积温>土壤积温>平均土壤含水量>平均空气相对湿度。
The effects of sugar beet staging sowing environmental factors on the brix and yield of sugar beet were studied to provide a scientific basis for the rational cultivation of sugar beet in Heilongjiang Province. The environmental factors, yield and sugar brix of KWS3418 under five different sowing dates were determined, and the correlation between them was analyzed. The results showed that sowing date had little effect on soil water content; temperature accumulated temperature was significantly and positively correlated with yield and sugar brix; in Hebei province, the sugar beet variety KWS3418 was suitable for early sowing; the correlation between environmental factors and yield was temperature accumulated temperature> accumulated soil temperature> Average soil moisture content> average air relative humidity.
