摘要
引进黑龙江省大豆品种黑河38,对不同播期处理的产量性状、生育期结构、叶面积指数消长、生物产量积累动态、器官平衡等进行了比较。结果表明:该品种在沈阳地区种植,随着播期延迟,生育日数逐渐缩短,最大叶面积指数下降、单株生物产量的积累减少。各播期间单株粒数、百粒重、小区产量差异显著,单位面积产量以6月9日播种最高,迟至7月11日播种,仍可获得较高产量,可作为春小麦或马铃薯下茬利用。以黑河、沈阳两地同期播种相比较,产量和品质差异较大。
There are few soybean varietes suitable for summer planting in Liaoning Province, and soybean germplasm introduced from higher latitude would solve this problem. The soybean variety Heihe 38, introduced from Heihe, Heilongjiang Province, was planted in Shenyang from 23th, April to 11 th, July. Yield character, structure of growing stage, dynamic change of leaf area index（LAI） and biomass accumulation and equilibrium of plant organ were determined. Result showed that biological yield accumulation ,LAI ,and growing days were decreased with the delaying of sowing time in Shenyang. The highest yield was got when Heihe 38 was planted on 9th June. There were significant difference of seeds per plant, weight of 100- seed and yield among different sowing date treatment, a good yield was also obtained when planting on 11 th July. There were significant difference on yield traits and quality between Shenyang and Heihe in the same sowing date. The results suggest that Heihe 18 can be planted in Shenyang as an relay - planting crop after harvesting spring wheat and potato.
