干旱是影响我省小麦生产的主要灾害天气之一。从小麦需水量看,我省大部分地区年平均降水在600—1000毫米之间,完全可以满足一般小麦产量对水分的需要。但由于雨量在季节上和地区上分配不匀,致使经常出现南涝北旱,春旱秋涝。特别近两三年来,我省中北部长时期的严重春旱,造成这些地区小麦大面积大幅度减产。据报导,我省小麦高产县的偃师县、温县八-年就是由于春旱而严重减产,为了探讨干旱对小麦的生理、产量及品质的影响,为抗旱种麦夺丰收提供一些理论依据,结合八二年抗旱在小麦
Drought is one of the major disastrous weather affecting wheat production in our province. Water demand from the wheat point of view, most of our province in the annual average precipitation between 600-1000 mm, fully meet the general wheat yield on the water needs. However, due to the uneven distribution of rainfall in the seasons and in the region, it has caused frequent occurrences of south floods, northern drought and autumn floods. In particular, in the past two to three years, the severe drought in the middle and northern part of our province led to a large-scale reduction of wheat in large areas in these areas. It is reported that in Yanshi County and Wengxian County in the high-yielding counties of wheat in our province, the eight-year period was severely reduced due to the spring drought. In order to explore the effect of drought on the physiology, yield and quality of wheat and provide some theoretical basis for drought-resistant wheat harvest , Combined with drought drought in wheat in 1982
