%X <span style=\"font-size:14px;\">本文对江孜县2005~2020年藏红花生长季的气象因子等资料进行分析，分析表明近16年江孜气温呈增长趋势，9月中旬~10月下旬藏红花球茎抽芽期间，江孜平均气温在7℃~12℃，满足藏红花生长；开花期江孜气温明显偏低，因此需要加温。降水主要集中在6月~9月。其中7月和8月总降水量占全年总数的35%；其余各月降水较少，少雨时段会影响藏红花的发根和出苗，需要松土适时浇水，保持田间土壤湿润，促进藏红花子球茎的壮大。江孜相对湿度较低，藏红花生长季相对湿度一般在80%左右，因此在这个期间需要增加大棚的相对湿度。江孜光能资源丰富，能满足藏红花生长季的光照需求。通过对藏红花种植各发育阶段的影响，为藏红花种植提供一定的科学依据。</span><br />
<span style=\"font-size:14px;\">This paper analyzes the meteorological factors and other data of the saffron growing season in Gyantse County from 2005 to 2020. The analysis shows that the temperature in Gyantse has shown an increasing trend in the past 16 years. During the budding period of saffron bulbs from mid-September to late October, the average temperature is 7？C~12？C in Gyantse, which meets the growth of saffron; the temperature in Gyantse during the flowering period is obviously low, so it needs to be heated. Precipitation is mainly concentrated in June-September. Among them, the total precipitation in July and August accounts for 35% of the total of the whole year; the precipitation in the rest of the months is less, and the period of less rain will affect the rooting and emergence of saffron. It is necessary to loosen the soil and water in time to keep the field soil moist and promote the growth of saffron. The relative humidity in Gyantse is low, and the relative humidity in the saf-fron growing season is generally around 80%, so it is necessary to increase the relative humidity in the greenhouse during this period. Gyantse is rich in light energy resources, which can meet the light demand of saffron growing season. Through the influence on each developmental stage of saf-fron planting, a certain scientific basis is provided for saffron planting.</span>
