摘要： 试验于1999～2001年在内蒙古中西部地区的呼和浩特市初步研究了麦茬复栽油用向日葵种植模式.研究结果表明:该地区适宜的油用向日葵移栽育苗时间是在6月25日前后,叶龄为8片展开叶,株高为40～50 cm;较适宜油用向日葵品种为新葵杂四号,其次是KWS;复栽油用向日葵的单产可达到2 820～ 570 kg/hm2.综合成本分析表明,麦茬后复栽油用向日葵种植模式比小麦单作经济效益提高101.81%,较单作油用向日葵提高6.92%.

Abstract: The authors began to primarily study the planting pattern of replanting oil sunflower afterwheat in Huhhot of the middle and western Inner Mongolia in 1999-2001.The results show :the optimum date was about Jun 25th to transplant oil sunflower seedling, expanding leaves was eight, and its height was 40 -50 cm;the optimum variety was Xinkuiza 4, secondary was KWS;the yield per area arrived at 2 820 -3 570 kg/ha in this planting pattern.According to synthesizing cost analysis, this planting pattern could increase economic profit 101.81 % than single wheat planting,63.92 % than single oil sunflower planting.
