摘  要:
为确定玉米在冀东地区日光温室加代繁殖中的适宜播种期,选择了春播玉米2个品种,夏播玉米5个品种(玉米杂交种4个,自交系3个)。对其在简易日光温室内的生长发育阶段及生育期特点进行了试验观察,明确了不同播期情况下各玉米品种的主要发育阶段特点,分析归纳出了玉米生育期依播种期变化的直线回归方程。

摘  要:
Two strains of spring-sown maize and five strains of summer-sown maize (4 strains of hybrid, 3 strains of purities) were selected for determining suitable sowing time of adding-generation propagation maize in sunlight greenhouse in East Hebei Province. The growth stages and characteristics of the maize in simply-equipped sunlight greenhouse were observed, the main developing characteristics of every strains in different sowing time were clarified, and the linear regression equation of growth period (Y) to date of planting (X) was analyzed and obtained.
