摘  要:
Three key factors,varieties,population density and PP333 which influence developmental process and yield formation of broadcast transplanted double rice crops in Tai lake region were studied.The results showed:The best set of techniques for early seasoned rice was cultivar Jiayu 293, basic seedling number of 2.4×10 6 or more per hectar and PP333 dosage of 450 g/hm 2 applied in the seedling field, while the best one for the late seasoned rice was correspondingly Zhengdao 88, 3.15×10 6 or more, and 450 g.
