For a long time, the crop varieties in dryland in Jingtai County are numerous, chaotic and miscellaneous, which seriously hampered the development of dry food production. In recent years, the county started from the crop varieties, through the introduction, testing, product ratio, screening work, from the 45 crop varieties out of the 78-141 wheat, Bei Nongyi wheat, tobacco single 14 corn, red meat sweet potato, Hebei Province, No. 11 Valley of Ji Valley, No. 2 Valley of Yugu Valley, No. 1 Sesame of Jizhi No. 1, No. 4 Soybean No. of Jizu No. 4, No. 1 of Middle Green No. 1, Peanut No. 4 of Peanut No. 4 and No. 4 Peanut. The promotion area is 100,000 mu, This has played a significant role in promoting grain production in dry farming areas. By contrast, these varieties mainly show the following four special
