In recent years, Lingtai County Agricultural Technology Center to actively explore ways to improve planting, summed up a dry plate clam Sorghum interplanting sorghum three-dimensional efficient cultivation techniques, a single planted as a composite planting, to achieve a quarter of two crops for the dry land Peasants increased production and opened up a new way. According to the survey, from 2004 to 2006, 28,000 mu of prunus mongolica intercropped sorghum in the county, with an average yield of 126kg per mu and 550kg of sorghum; an increase of 87.3% over that of a single prickly heat and an increase of 87.3% over that of a single type of sorghum Yuan, an increase of 28.8%.
