The city is located in the northeastern edge of Hebei Province, with an average of 2,770.2 hours of sunshine and 180 days of frost-free period. The annual rainfall of 698.5 mm, of which 618.6 mm in early April to early September, rainfall characteristics are: two less, the middle and more meteorological conditions are suitable for spring maize production, therefore, the main grain production of corn, dry land accounted for maize The total sown area of 93.3%. Since the establishment of the Collaborative Group on Maize Cultivation in 1978, the area under maize cultivation has increased from 33.5% of the total grain output in 1978 to 62% in 1983, with the total output accounting for 63% of the total grain output in the year. In 1978-1983, the average yield per mu for a 6-year period was 847.8 kilograms. In 1983, the average mu yield was 862 kilograms. The main technical measures are as follows.
