【摘要】 采用育苗移栽方法研究了对生玉米杂交种对玉 99- 3的生长发育特性及产量构成规律 ,结果表明 :对生玉米杂交种株形紧凑 ,单株总叶数、叶面积、单株产量、抗旱性等方面都明显优于互生玉米。对生玉米杂交种具有较大的增产潜力。通过进一步选育改良 ,将来有望应用于生产更多还原

【Abstract】 By transplanting, the oppositifolious maize DUIYU99 3 has been studied in the growth characteristics and the rules of yield constitution . The result shows that the oppositifolious maize DUIYU99 3 has obvious superiority than the mutual maize in the compact shape, the total of leaves, leaf area, the yield of every strain and drought resistance. It has a large potential on the respect of increasing yield, and it will be applied on farm after being improved deeply .更多还原
