本文探讨了适期早播对大豆“满贯”生长发育规律及产量的影响.结果表明,不同播期处理,大豆叶面积指数增长和生物产量的累积动态有所不同,大豆适期早播使始花期提前,末花期不推迟,全花期延长,最终产量差异达极显著水准.
The effects of early sowing date on growth and development and yield of Soybean “Slam” were studied in this paper. The results showed that the accumulation of Soybean leaf area index and biomass was different under different sowing dates. The initial flowering period, the late flowering is not delayed, the full flowering extended, the final output difference reached a significant level.
