1 种株培育1.1 播种育苗早熟春甘蓝双亲的生育特点有明显差异,对两个亲本冬前苗子大小的要求也不相同,因此,应掌握好适期播种,总的来说,因圆球型属晚花型,其半成株的开花期比成株的开花期提早3～5天;相反,尖球类型属早花型,其半成株的开花期比成株的开花期略晚。这种现象有利于花期相遇,所以,将早熟春甘蓝的双亲都适当晚播,使之在冬前长成具有松散叶球的半成株,增加春季花期相遇的机会。根据试
1 seed culture 1.1 sowing seedlings early spring cabbage parents have significant differences in the characteristics of reproduction, the size of the two parents of pre-winter seedlings are not the same, therefore, should grasp the appropriate sowing, in general, due to spherical The late flowering type, the semi-mature flowering stage than the adult flowering stage early 3 to 5 days; the contrary, the tip type is early flowering, semi-mature flowering stage than adult flowering slightly later. This phenomenon is conducive to the flowering encounter, therefore, early maturing spring cabbage parent appropriate late sowing, so that before winter, grow into semi-mature with loose leaf ball, increase the chance of spring flowering encounter. According to the test
