摘要
对小麦拔节期到开花期的气孔阻力(或其倒数气孔导度)进行分析认为,影响小麦气孔阻力(气孔导度)的主要气象因子是光照强度和水汽饱和差,并对它们进行了计算,效果较理想。这使得利用常规观测得到的气象资料计算作物气孔阻力成为可能。同时,还根据计算和观测的结果,分析了小麦气孔阻力的变化规律。
Abstract Wheat stomatic resistance from jointing to flowering phaseis analysed. It shows that main weath-er factors which affect wheat stomatic resistance are light intensity and air humidity. The simulationmodel is set up, and is satisfied.SO it is possible to calculate crop stomatic resistance by routine data ofwcather observation. According to the calculation and observation, analysed the varational features ofwheat stomatic resistance. Kcy words:Wheat Stomatic resistance Weather factors
