漯河市是河南省小麦生产的特殊生态区。其光温等自然气候条件虽然适宜小麦生长,亩产比较容易达到250—300kg。但因其处于北亚热和暖温带气候交界区,南北两种气候类型中对小麦生长发育不利的因素共存(如阴雨、干旱等),达到豫北高产区产量水平有很大困难。特别是年际间降水量的大幅度波动(5月份旬降水量年际间波动达10倍以上),对小麦品种的适应性和栽培技术要求都较高。为了使该区小麦产量再上新台阶。漯河市“一二五工程”小麦高产开发协作组,通过大量的调查、试验和分析,总结出了五项适 Luohe City, Henan Province, wheat production is a special ecological zone. Its natural light and temperature and other natural climatic conditions, although suitable for the growth of wheat, mu yield is relatively easy to reach 250-300kg. However, due to the coexistence of negative factors (such as overcast and drought) in wheat growth and development in both North and South climate types, it is very difficult to reach the yield level in the high-yielding areas of North of Henan Province because of its north and subtropical temperate climatic junction. In particular, the large-scale fluctuation of annual precipitation (more than 10 times of annual variation in the monthly precipitation in May), the adaptability to wheat varieties and cultivation techniques are high. In order to bring the area’s wheat production to a new level. Luohe City, “one two five” wheat high yield development collaboration group, through a lot of investigation, test and analysis, summed up the five fitness
