以常规早籼稻中早39为试验材料,通过研究不同播种量与壮秧剂用量对水稻秧苗素质和产量的影响,来确定中早39在当地的最佳播种量和壮秧剂使用量。结果表明,机插秧播种量以125~150 g/盘为宜,壮秧剂适宜用量为50~75 g/m2。
Using the early-season indica rice Zhongzao 39 as material, the tests concerning different seeding rate and dosage of seedling strengthen agent were conducted. The results indicated that the proper seeding rate is 125~150 g per disk and the reasonable dosage of seedling strengthen agent is 50~75 g/m2.
