小麦是关中地区的主要作物,其产量丰欠与气候关系极切。如1979—80年小麦生育期间长期干旱,春季又受低温影响,水旱地均减产。1980—81年小麦生育期间雨水适时,气温适宜,虽后期高温干旱,干热风,但干热风出现的早,影响不大,取得罕见的丰收。两年事例充分说明气候与小麦生产关系的密切性。 Wheat is the main crop in the Guanzhong region and its production is extremely dependent on the climate. Such as 1979-80 years of prolonged drought during wheat growth, spring is affected by low temperature, water and dry land are reduced. During the period of 1980-81, the rainwater was timely and the temperature was suitable during the wheat growing period. Although the later period was hot and dry with hot and dry wind, the dry and hot wind appeared early and had little effect and achieved rare harvest. Two years of examples fully illustrate the close relationship between climate and wheat production.
