【摘要】 利用实测资料分析得出新疆主要红花产区≥5℃积温基本符合红花生长的需求,故选用≥5℃积温值作为红花适生种植区划的主导指标;其次实验观测发现红花在苗期温度低则分枝多,花期温度高则花盘大、产量高,灌浆期温度低则籽粒饱满,故将这三个关键生长期的平均气温作为辅助指标。据此进行了红花适生种植气候区划,并提出了充分利用气候资源在南疆种植复播红花的新思路更多还原

【Abstract】 By analyzing the observation data in main producing Carthamus tinctorius L. areas of Xinjiang,the results showed that the accumulated temperature (≥5℃)was match to the requirement of Carthamus tinctorius L. growing, and the low temperature during seedling stage would make more branches, and the high temperature in blooming period would make bigger flower and high yield, and the low temperature during grouting period would make more fertile seeds. So the accumulated temperature (≥5℃)was recommended as the primary index and the daily average temperature during three key growth phases such as seeding stage, blooming period and grouting period,as an assistant index to regionalize the climatic compartment of Carthamus tinctorius L. in Xinjiang.更多还原
