小麦遭受高温,产量降低.这种降低取决于在分蘖、小穗、小花和籽粒形成阶段,温度的提高使它们的数量有所减少(Evans和Wardlaw,1976).利用可控的环境设备,测定上述生长阶段作物对温度的反应,是可以避免田间难以解释的变化的.然而,这些数据的推断再回到田间去验证可能是困难的,因为在温度和其他环境变化之间可能相互有影响.养分效应是环境因素之一,它能减轻小麦
Wheat is exposed to high temperatures and yields are reduced.This reduction is due to a decrease in the number of tillers, spikelets, florets and kernels as temperatures increase (Evans and Wardlaw, 1976). Using controlled environmental equipment, The response of crops to temperature during the growth phase described above can avoid uninterpretable changes in the field, however, extrapolation of these data back into the field to verify can be difficult because of possible interactions between temperature and other environmental changes. Nutrient effect is one of the environmental factors, it can reduce wheat
