摘要
甘肃河西走廊是中国最大的杂交玉米种子生产基地,干旱、缺水是制约该区玉米制种产业发展的瓶颈因素。对6种不同栽培模式下制种玉米的产量表现和水分利用效果进行对比研究,结果表明:全膜覆盖、垄植和沟播栽培模式均有利于提高制种玉米的产量和水分利用效率。其中,全膜覆盖沟播栽培模式节水增产效果最为显著,比对照半膜平作增产1 730.8kg/hm2,水分利用效率提高0.412kg/m3。
Abstract：The Hexi corridor of Gansu Province is the biggest production base of hybrid seed corn in China. Drought and water short- age are the bottleneck factors that limit the seed corn industry development in that area. The yield and water use effect under six different cultivation modes are studied in this paper. The results show that the three cultivation methods, including whole covered with plastic film, raised bed planting and furrow planting, are advantaged to improve the yield and water use efficiency. Among them, the cultivation method of whole covered with plastic film raised-bed planting has the most obvious effect of yield increasing and watersaving. Compared with CK of half covered with plastic film flat planting, the yield is increased by 1 730. 8 kg/hm2 and the water use efficiency is improved bv 0. 412 k~/ma.
