干热风是影响小麦高产(禾文)产的主要灾害之一。农谚有“麦怕四月(农历)风,风过一场空”。“小满不满,麦有一险”的说法,就是指的干热风。在五月中下旬,正当小麦浂浆、乳熟期间,我省常出现干热风。小麦受干热风危害后,一般减产10%左右,重则减产20%以上,予东沙区更为严重,因此,我们在睢县屈庄进行了调查,开展了防御小麦干热风的研究。 Dry hot air is one of the major disasters that affect the high yield of wheat (WoWen). Agricultural proverb “Mai fear April (Lunar) wind, the wind had an empty air.” “Xiaoman dissatisfaction, wheat has a risk,” saying, refers to the dry hot air. In mid-to-late May, while wheat pulp, milk cooked during my province often appear dry hot air. After the wheat is harmed by the hot and dry winds, it generally reduces the output by about 10% and reduces the output by more than 20% to the Dongsha District. Therefore, we conducted a survey in Yizhuang County of Yixian County and conducted a study on the defensive wheat dry-hot wind.
