| 摘 要： | 目的]为了解决在生产中黑皮大豆庐州黑农艺措施不当、单产不稳的问题,发挥该品种的增产潜力。方法]采用正交试验设计L(934)研究播期、密度、施氮量对优质黑皮大豆庐州黑产量的影响。结果]播种期为5月31日,密度为10.5万株/hm2,施纯氮为69.0kg/hm2处理的产量居第一位,达4183.5kg/hm2。结论]庐州黑为迟熟大豆品种,对温、光条件较为敏感,在巢湖市种植的适宜播期为5月下旬、密度为10.5万株/hm2,中等肥力地块施纯氮37.5～52.5kg/hm2;低肥力地块施纯氮52.5～67.5kg/hm2;高肥力地块不施或少施氮素。

| Abstract: | Objective] The purpose was to solve the problems of improper agronomic measures and unstable single yield in the production of black soybean Luzhouhei and develop its increase potential. Method] The influences of seeding date, density and nitrogen application on the yield of Luzhouhei were studied by orthogonal test design L9 (34). Result] The yield of seeding at 31st May with density at 1.05 × 105 plants/ha and fertilizing 69.0 kg/ha pure nitrogen was the first, being 4 183.5 kg/ha. Conclusion] Luzhouhei was late-maturing variety and more sensitive to temperature and light. For planting in Chaohu City, the suitable seeding date was late May, density was 1.05 × 105 plants/ha, pure nitrogen application was 37.5~52.5 kg/ha and 52.5~67.5 kg/ha in middle and low fertility lands and was no or less in high fertility land. |
