【摘要】 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.更多还原

【Abstract】 Proper early sowing to let soybean to have "full season" development can increase LAI andaccumulate biological yield of soybean. Under proper early sowing condition first flowering ap-pears earlier and appearance of last flower is postponed, and flowering season is then prolorged,yield then increases significantly.更多还原
