摘  要:
棉花高能期与高能季节同步性较好的处理比同步性较差的处理增产19.71%(r=0.7701)。同步期长短与产量呈极显著正相关(r=0.9315),其回归方程Y=169.40+3.24x;同步期成铃强度与产量也呈极显著正相关(r=0.8268),其回归方程Y=127.14+10.97x。因此,增加同步时间和提高成铃强度,是棉花高产优质的主攻方向。 同步性较好的处理,在同步期内积累的总干物重和生殖器官干物重分别为584.7,289.3kg/亩,各占一生中的64.6%,69.6%,比较差的处理分别高37.74%,87.25%;同步期成铃数为5.32万个,占最终成铃数的82.4%,比较差的处理高42.9%;同步好的光能利用率平均为1.73%,比较差的处理平均高0.50%。

摘  要:
The yields of cotton with better synchronism between actively energyconserving period and high energy season were 19.71% (r=0.7701) higher than those with poorer synchronism. The cotton yields showed a significantly positive correlation with the synchronous time (r=0.9315) and set intensity of cotton (r=0.8268) and their regression equations were y=169.40+3.24x and y=127.14+10.97x, respectively.Dry weight of the whole plant, dry weight of reproductive organ and boll number formed during the synchronous period of better synchronism exceeded those of the poorer by 37.74%, 87.25%, 42.9%, respectively.
