户单1号是我省户县种子公司利用引进的黄早4作母本与莫17杂交而成,具有早熟、高产、抗病、制种方便等特点。现已在我省夏玉米地区推广。为探讨该品种的高产生理基础,近几年我们进行了一些试验与调查研究。一、生育特点与一些生理特性 1.生育进程:据1981—1983年观察,生育期97—100天。播种至出苗7天,出苗至拔节25天,拔节至抽雄20天,抽雄至成熟38—40天。夏播播期对生育进程影响不大。见表1。
Household No. 1 is the province of Huxian seed companies to use the introduction of the yellow as early as 4 mother made with the hybrid Ma 17, with early maturity, high yield, disease resistance, easy to seed and so on. Now in the province of summer corn to promote. In order to explore the high-yielding physiological basis of this variety, we conducted some experiments and investigations in recent years. First, the characteristics of reproductive and some physiological characteristics 1. Fertility process: According to 1981-1983 observation, the growth period of 97-100 days. Sowing to emergence 7 days, emergence to jointing 25 days, jointing to tasseling 20 days, tasseling to mature 38-40 days. Summer sowing period has little effect on the fertility process. See Table 1.
