Tianxian County is a mountainous area in southwestern Guangxi. Grain production mainly uses corn. In the past two years, we have focused on the production of late maize seeds, matching the combination of natural conditions, reforming seed production techniques, reforming the seed production system and increasing the yield and quality of hybrids. In late 1987, 3246.95 acres of maize were planted with an average yield of 174.4 kilograms per mu and a maximum yield of 449.3 kilograms per mu. Despite the serious threat of autumn drought, the average yield per mu is still 175 kg, of which 1074 mu of high-yield demonstration project prepared “South School No. 8 × Mo Bai 1” with an average yield of 289 kg per mu ,highest
