山区地型复杂,气候特殊,因此根据小麦气候生态的特异性,采取相应的技术对策,趋利避害,是一条有效增产途径。一、山区的气候特点1.山区地表面积大,散热快,一年中以3～11月的气温变化明显,海拔每升高100米气温下降0.4℃。以6月、9月相差最大,3月、11月变化最为强烈。冬季气温相差不明显。从气温、地表温度、5cm 地温、10cm 地温……纵向剖析,温度与海拔高度的年变化总体趋势,呈抛物线型,即积温减少的趋势为:地
Mountainous terrain is complex and has a special climate. Therefore, according to the specificity of wheat climatic ecology, it is an effective way to increase production by adopting appropriate technical countermeasures and avoiding disadvantages. First, the mountain climate features 1. Mountain area of large surface area, heat dissipation, a year to 3 to November temperature changes significantly, elevation of 100 meters for each elevation of 0.4 degrees Celsius. In June, September the biggest difference, March, November changes the most intense. Winter temperature difference is not obvious. From the temperature, surface temperature, 5cm ground temperature, 10cm ground temperature ... ... longitudinal analysis, the annual trend of temperature and altitude overall trend, showing a parabolic pattern, that is, the trend of reducing the accumulated temperature:
