【摘要】 玉米栽培应突出玉米的生物学特性。玉米是典型异花授粉作物,杂交当代起就有杂种优势。玉米的主要功能叶是棒三叶,边行优势大,叶面高光效。在玉米栽培形式上应适应玉米生物学特性。将目前大面积清种改成株高、品质、育性不相同的3个杂交种按一定行比间种,形成波浪起伏的立体栽培,可充分发挥和利用玉米生物学特性,稳产、丰产,改善玉米的品质,降低生产投入,提高效益。更多还原

【Abstract】 Maize planting technology should emphasized biology characteristic.Maize is the representative cross pollination crop,had better photosynthetic efficient and the marginal effect.Mostly function leaves were ear-leaf and the below and above ones.Solid cultivation was planting three different hybrids together,such as different qualities or plant heights,based on row proportion.Solid cultivation promoted to use maize biology characteristic,promoted yield and quality etc.更多还原
