Select high-quality improved varieties, generally choose mid-late maturity varieties with high yield potential, strong density tolerance and large panicle type to ensure strong lodging resistance and good disease resistance.
The varieties with strong lodging resistance have hard stems and developed roots. Varieties with strong disease resistance are resistant to leaf spot in high population, such as Zheng Dan 958, Agricultural University 108, Denghai No.9 and Lu Dan 98 1 planted in Shudong Town. Seed purity is higher than 96%, germination rate is higher than 85%, and purity is higher than 98%. If a single seed is sown with precision, the germination rate of the seed should be above 94%.
