广灵县全县有近51.6万亩耕地,就有34.9万多亩旱地,其中20万亩山区丘陵旱地历年产量低而不稳。这种落后的土地条件,加上不太理想的气候因素,使广灵县的小麦生产难以发展。平川区和丘陵区试种过冬小麦,因不能正常越冬而失败。平川区多年推行种植春小麦,由于干热风为害不断发生,至今种植面积不足百亩。 1985年,广灵县开始引进夏播小麦。望
There are nearly 516,000 mu of cultivated land in Guangling County. There are 349,000 mu of dry land. Among them, 200,000 mu of mountainous hilly dry land have low and unstable annual output. This backward land conditions, coupled with less than ideal climatic factors, make wheat production in Guangling County difficult to develop. Hirakawa and hilly areas have been planted with winter wheat, because they can not normally win over the failure. Hirakawa for many years to promote the cultivation of spring wheat, due to dry and hot wind damage continue to occur, so far less than acres planted area. In 1985, Guangling County began to introduce summer sowing wheat. hope
