河南小麦生长期长(230天左右),经历秋冬春夏四个季节,旱、冰雹、大风、霜冻、干热风等气象灾害频繁。为了更好地发挥优良品种的优质高产特性,确保下年小麦增产丰收、农民增效,有必要对河南气候、不同生态麦区做以分析,提出种植参考品种。一、气候特点及其多样性河南具有四季分明、雨热同期、复杂多样、气象灾害频繁等气候基本特点,存在着自南向北亚热带向暖温带气候过渡、自东向西由平原向丘陵山地气候过渡的两个特。气候多样性和气候过渡
Henan wheat grows long (about 230 days), experiences four seasons of spring and summer of autumn and winter, and frequent meteorological disasters such as drought, hail, windy, frost and dry hot wind. In order to give full play to the high quality and high yield characteristics of elite varieties, ensure the yield increase of wheat in the next year, and increase the efficiency of farmers, it is necessary to make an analysis of Henan climate and different ecologic wheat areas and propose planting reference varieties. First, the climate characteristics and diversity Henan has four seasons, rain and heat over the same period, complex and diverse, frequent meteorological disasters and other climate basic characteristics, there is a transition from warm to warm temperate climate from south to north, from plain to hilly mountains from east to west Two specialties of the climate transition. Climate diversity and climate transition
