To explore the relationship between the growth of Yu-1 corn organs, master these laws in order to provide a basis for the development of high-yielding cultivation techniques. First, the test method Yuyu one early maturity corn single cross, 19 leaves per plant, ears with the last sixth leaf position, the whole growth period of 89 days. Summer planting in 1985, sowing the right time, planting 3750 acres of mu, 450 kg of mu production. Field fixed sample 5,
