山区地形复杂,气候特殊,因而山区小麦生产也应采取相应的技术策略,趋利避害,才能获得较高的产量。自1986年以来,我们在涉县不同类型区进行了连续的试验、观察,总结出了一套对应技术,推广41万亩,取得经济效益2200余万元。一、山区气候特点: 山区地表面积大,散热快,海拔高度每升高100米,气温下降0.4℃。一年中的气温,以3—11月变化明显,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、5厘米地温、10厘米地温到15厘米以下地温纵向剖析,随着海拔高度的增加,积温减少的趋势为:地表积温较气积温明显,5厘米较地表更明显,15厘米减少到最大值,以后随深度的增加,减少回缓。海拔高度每增加100米,小麦成熟期推迟1.5—2天,且叶
Mountainous terrain is complex, the climate is special, so mountainous area wheat production also should adopt the corresponding technical strategy, seek benefits and avoid damage, in order to obtain higher yield. Since 1986, we conducted continuous tests in different types of districts in Shexian County, observed and summarized a set of corresponding technologies to promote 41 million mu and achieved economic benefits of more than 22 million yuan. First, the mountain climate characteristics: mountainous area of large surface, fast cooling, elevation of 100 meters above sea level, the temperature dropped 0.4 ℃. The temperature in the year changed obviously from March to November, with the biggest difference in June and September, and the change was most intense in March and November. Winter temperature difference is not obvious. From the temperature, surface temperature, 5 centimeter ground temperature, 10 centimeter ground temperature to 15 centimeter below the ground temperature longitudinal analysis, with the increase of altitude, the accumulated temperature decreases: the surface temperature is more obvious than the gas accumulated temperature, 5 cm more obvious than the surface, 15 cm Reduce to the maximum, with the depth of the increase, reduce back to slow. For every 100 meters above sea level, wheat maturity is postponed for 1.5-2 days, and leaves
