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％。
The treatment with better synchronization between high-energy and high-energy seasons increased 19.71% (r = 0.7701) compared with the less synchronized treatment. There was a significant positive correlation (r = 0.9315) between the length of synchronization and yield, the regression equation was Y = 169.40 + 3.24x. The boll intensity and yield were also significantly positively correlated (r = 0.8268) 127.14 + 10.97x. Therefore, increasing the synchronization time and increasing the intensity of bolls is the main direction of high yield and quality of cotton. The results showed that the total dry matter weight and the dry weight of reproductive organs accumulated during the synchronization period were 584.7 and 289.3 kg / mu respectively, accounting for 64.6% and 69.6% of the total lifetime, respectively, compared with 37.74% 87.25%. The number of bells in the synchronization period was 53,200, accounting for 82.4% of the final number of bells and 42.9% of the worst. The average utilization rate of synchronic light energy was 1.73% and the average treatment rate was 0.50% .
