干旱风是小麦生育后期常常发生的一种災害性天气康贝合闹?北方干冷的气流南下侵入华北地区,增温变性,因高气压位置的关系,淮北地区往往形成干热的偏西南气流,群众称为“西南风”,又称为“火风”。淮北地区每年春末夏初,正当小麦灌浆到成熟期间,常遭受干旱风的危害,使植株迅速失水,“急死”“假熟”,不仅会形成疮粒,千粒重减轻,严重地影响产量,而且也会影响小麦质量,降低出粉率,出现所谓“风干不实”和“籽粒干疮”的现象。正如群众所说:“‘小满’不满,‘芒种’不管”“麦到‘芒种’怕假麦”等,都说明麦到“小满”尚未顶满仓、灌满浆,极易受災而导致减产虼?进一步研究干旱风发生规律,探讨经济有效的防御措施,是争取小麦高产稳收的一项值得重视的研究课题。 Arid wind is a kind of disastrous weather which often occurs in the late stage of wheat growth. The dry and cold airflow in the north intrudes into the North China area, which causes the temperature and denaturation. Due to the high atmospheric pressure position, the dry and warm southwest of Huaibei usually forms Air flow, the masses called “southwest wind”, also known as “fire wind.” In the late spring and early summer of each year in Huaibei region, wheat is often endangered by arid wind during grain filling to maturity, causing rapid water loss. Rapid death and fake ripening will not only result in the formation of sores and reduce the grain weight, but also seriously affect the yield, But also affect the quality of wheat, reduce the rate of flour, the so-called “dry” and “dry seized grain” phenomenon. As the masses said, “Little Man’s dissatisfaction”, “Manchu no matter”, “Wheat to ’Manchu’ ’s fear of fake wheat,” etc. all show that wheat has not yet reached the peak of full capacity and is prone to suffer losses and lead to a decrease in output Further research on the occurrence of drought wind and the discussion of cost-effective defensive measures are worthy of our attention in this field.
