摘要
生物学温度指标是某一品种应用范围和运用栽培技术措施的一个重要依据。本文以谷子牡育6号为例,分析各不同生长发育阶段和整个生育期所需生物学下限温度、有效温度和活动积温指标值。全生育期所需生物学下限温度为7.0℃,有效温度1435.9℃,活动积温为2213.8℃。在应用某一品种时不仅以全生育期生物学温度为依据,更应注意各不同发育阶段生物学下限温度值、有效温度值和活动积温值等参数。
Biological temperature target is an important basis of selecting planting range and planting technique for a variety. Here is an analysis of biological low temperature, effective accumulated temperature and active accumulated temperature in different growing period and all growing duration. For example the biological low temperature of Grain No. 6 bred by Mudanjiang agricultural research insitute is 7. 0C , effective accmulated temperature 1435. 9C and active accumulated temperature 2213.8C. When planting, not only should we be according to the target of biological temperature in all growing period, but also pay more attention to the target of biological low temperature, effective accumulated temperature , and active accumulated temperature in different growing periods.
